Suresh Joghee,   Nagamani

Abstract
Natural  products  of  plant  and  animal  origin  offer  a  vast  resource  of  newer medicinal  agents  with  potential  in  clinical  use.  Some  of  these  are  believed  to  promote  positive  health  and  maintain  organic  resistance  against  infection  by  re-establishing  the  body’s  equilibrium  and  conditioning  the  body  tissues.  Artemisia abrotanum  commonly  known  as  “Southern  wood”  traditionally  considered  as  antiseptic,  astringent,  emmenagogue,  expectorant,  febrifuge,  stimulant,  tonic,  anti inflammatory,  vermifuge,  spasmolytic  and  used  for  treating  upper  respiratory  tract  disease.  An  infusion  makes  a  bitter  tonic,  used  against  cancer,  cough  fever  and  tumors. Ethanolic  extract  of  Artemisia  abrotanum  was  administered  orally  at  doses  of  100  and  200  mg/kg/day  to  healthy  mice  (Albino)  divided  into  three  groups  consisting  of  six  animals  each.  The  assessment  of  immunomodulatory  activity  was  carried  out  by  testing  humoral  (antibody  titer)  and  cellular  (foot  pad  swelling)  immune  responses  to  the  antigenic  challenge  by  sheep  RBCs.  Oral  administration  of  extract  showed  a  significant  decrease  in  delayed  type  hypersensitivity  (DTH)  response  and  the  humoral  response  to  sheep  RBCs.  Ethanolic  extract  of  AA  shows  non-significant  reduction  in  primary  antibody  titer and  at  the  doses  of  200mg/kg/day  shows  significant  reduction  in  secondary  antibody  titer  and  foot  pad  thickness

Walvekar M. V., Deshmukh V. M., Pol S. B.
Abstract
The study was undertaken to evaluate protective effect of fenugreek seed extract (FSE) on the salivary glands of aging induced mice. For that we have studied the histology as well as histochemistry of the salivary glands. So to evaluate protective effect of fenugreek against accelerated aging, male albino mice (Mus musculus L.) were divided into four groups viz, a) Control group- received subcutaneous injection of 0.5 ml sterile water for 20 days. b) Aging accelerated group- received injection of 0.5 ml of 5% of D-galactose/ day for 20 days. c) Protective group- received injection of D-galactose + FSE (50 mg/kg body weight of animal) for 20 day. d) Curative group- received D- galactose for 20 days then after FSE (50 mg/kg body weight) for 20 days. The histological study by HE showed loss of their normal architecture and cellular integrity .Histochemical study by PAS, AB-1, AB-2.5 showed decreased staining intensity of salivary glands in D-galactose injected aged mice as compared to control. While protective and curative groups showed recovery in architecture of salivary acini and increase in acini number. Increased staining intensity indicates increase in glycoprotein content. Better results are seen in curative group as compared to protective group. Thus above results elucidate the protective action of fenugreek seeds against aging in salivary glands of mice.

Abstract
The present study was conducted with the objective of phytochemical investigation, safe dose determination and evaluation of anti-inflammatory activity of the toluene and methanolic extract of whole plant of Dipteracanthus prostratus Nees.. Preliminary phytochemical investigation was performed after the successive extraction of whole plant of Dipteracanthus prostratus and found to contain a rich amount of important bioactive compounds. The dose determination studies were carried out according to OECD guidelines no. 425 on Wistar albino rats and the safe dose determined was 2000 mg/kg. Hence on the basis of toxicity studies two dose level i.e. 100 mg/kg and 200 mg/kg, body weight were selected for the present anti-inflammatory activity using carrageenan induced paw edema model. The percentage reduction in paw volume observed against carrageenan induced paw edema for toluene extract was found to be 20.68% and 25.86% at the dose level of 100 mg/kg and 200 mg/kg, body weight respectively whereas in methanolic extract it was 17.24 % and 22.41% at the dose level of 100 mg/kg and 200 mg/kg, body weight respectively. The data were found statistically significant by using one way ANOVA (P<0.05). Although both the extracts were able to exhibit anti-inflammatory activity as compared with standard drug Diclofenac Sodium but the overall effect of toluene extract of whole plant of Dipteracanthus prostratus at the specified dose level of 200 mg/kg, body weight was found to be more statistically significant compared to methanolic extract

11. Phytochemicals as Antimicrobial Agents Against Opportunistic Candidiasis: A Review
Amit Bhattacharya, Hardeep Kaur
Abstract
Globally, over 300 million people suffer from a serious fungal infection and about 25 million of them have high risk of dying or loss of sight. The serious fungal diseases can be either severe (such as cryptococcal meningitis and fungal eye infection), periodic (such as Candida vaginitis or oral candidiasis in AIDS patients) or chronic (such as chronic pulmonary aspergillosis or fungal hair infection). Candida albicans is accountable for most fungal infections in humans. The vaginal yeast infection, termed as vulvovaginal candidiasis or vulvovaginitis, and oral candidiasis, a common type of yeast infection that occurs on the tongue or palate as thick white patches, are most common yeast infections found in humans. Invasive mycoses, mainly caused by Candida, are life-threatening opportunistic infection that has emerged as a major cause of morbidity and mortality in hospitalized patients. Despite the introduction of new and novel antifungal drugs, growing antifungal resistance is a major health concern for the clinicians and researchers across the globe. Phytochemicals represents the most abundant and extensively distributed substances in the plant kingdom. Several woody plant and herb cells produce and gather these range of medicinal phytochemicals such as phenolic compunds (hydroxybenzoic and hydroxycinamic acids, acetophenone, and flavonoids), oligo-or polymeric compounds (such as tannins and lignins) etc. The developing antifungal drug resistance has forced the attention of researchers towards herbal products, mainly phytochemicals, in search of development of novel, safe and economically viable antifungals

Zarshenas Mohammad M., Sakhteman Amirhossein, Etemadfard Hamed, Moein Mahmoodreza
Abstract
Essential oil and hydrosol of Trachyspermum ammi (L.) Sprague (Apiaceae) are traditionally applied for chronic pain and neural ailments such as tremor, paralysis, and palsy. Unlike numerous studies on the chemical composition of T. ammi essential oil, no certain report has been performed on the hydrosol chemical compositions. Current study aimed to chemically evaluate different T. ammi hydrosols. Ten hydrosol samples collected from Fars (Iran) markets and as well as a standard hydrosol were subjected to GC and GC/MS following recovering by a liquid extractor. Hierarchical Cluster Analysis and Principal Component Analysis methods were performed to determine the similarity of those samples. Out of 14 constituents identified in studied sample, thymol (84.33-95.62%) was found as the main component (97.77% for the standard hydrosol). Cluster Analysis divided the samples into two main groups. As a by-product in the extraction of plants’ essential oil, T. ammi hydrosol can be considered as an almost pure, but cheap and easy producible resource of natural thymol. In accordance with the pharmacological properties of thymol, this preparation can be applied in numerous relevant clinical and phytopharmaceutical approaches.

Abstract
Antioxidative and antidiabetic compounds were successfully extracted from Musa spp. ABB cv. (Pisang Awak) leaves. Effects of extraction time (0.5–4 h), solvent-to-sample ratio (10–80 ml/g), ethanol concentration (50–100 %), extraction temperature (25–60 °C) and pH (2–7) were examined. The selected key variables were optimized using response surface methodology (RSM). Quadratic models were obtained and 3D-response surfaces were plotted. An optimum condition (i.e. extraction time of 0.5 h, solvent-to-sample ratio of 48.3 ml/g and 88.5% ethanol) was obtained. This condition gave TPC of 21.54 mg GAE/g sample, DPPH scavenging activity of 6.49 mg GAE/g sample, FRAP of 9.35 mM Fe2SO4 and a-amylase inhibition activity of 26.62%. A total of 7 major compounds (i.e. chlorogenic acid, procyanidin, epicatechin, rutin, isoquercitrin, quercetin and kaempferol-7-neohesperidoside) were identified using liquid chromatography-quadropole time-of-flight-mass spectrometer.

Razali Mohamed Salleh, Mizaton Hazizul Hasan, Aishah Adam
Abstract
Roots of Prismatomeris glabra (P. glabra), family Rubiaceae, have been traditionally used by rural indigenous people for wellness and stamina purposes. However there is no scientific evidence to support the folkloric use of this plant. Ergogenic effects were studied in weight-bearing mice (load: 10% of body weight) by a modified forced swim test (FST) following treatment with PG. Control groups were given vehicle or L-arginine. Effect was studied on exercised and non exercised groups. Nine exercise bouts were performed with each bout comprising of 3 consecutive days of FST till exhaustion and a rest day between bouts. Body weight, water and food intake were recorded. Mice were killed immediately after the final FST and blood was collected for glucose, lactate and serum assays. Serum corticosteroid was measured using enzyme immunoassay (EIA) kits. Results showed that mice treated with P. glabra exhibited significantly greater exercise performance than control (p=0.000) or L-arginine (p=0.001) groups. Effect of P. glabra on post-exercise blood glucose was greater than control exercised group (p=0.011) but similar to control non-exercised and L-arginine groups. Effect of P. glabra on blood lactate was similar to all other exercised groups. Serum cortisterone of P. glabra-treated group was significantly higher (p<0.001) than that of control non-exercised group, but similar to control exercised and L-arginine groups. In conclusion, findings of this study provide evidence to confirm the traditional use of P. glabra roots for improving stamina and physical performance.

Abstract
The use of medicinal herbs in traditional system of medicine is a common practice in many cultures around the world, especially in African society. Medicinal plants are a great source of bioactive molecules for treatment of different pathology. Khaya senegalensis A. Juss belongs to the family Meliaceae. Khaya species are highly priced in traditional medicine in Bénin. The present study aims to: (i) evaluate the phytochemical, antiradical and antihyperglycemic activities of aqueous extract of stem bark of K. senegalensis; (ii) determine the effect of aqueous extract of K. senegalensis stem bark on liver function parameters wistar rats. The screening was performed for triterpenoids, alkaloids, anthraquinones, coumarins, flavonoids, saponins, tannins, anthocyanes, leucoanthocyanes, reductor sugar, mucilage and Cyanogenic compound. The color intensity or the precipitate formation was used as analytical responses to these tests. The total antihyperglycemic capacity was evaluated by using the complex method. Antiradical activity was made by using the DPPH method. Toxicological evaluation of aqueous extract of K. senegalensis stem bark on some liver function parameters of wistar rats (150-200g) were critically examined. Results from phytochemical screening indicated the presence of high level of phenolic compounds and alkaloids in bark-stem of K. senegalensis. With a concentration of 491.11 ± 20.67 mmolEAA /mg, the plant was determined to have a high potential antioxidant activity.  Moreover, an increase of concentration to 2000 mg/kg was non-toxic for the rats. No toxicity activity was observed. Blood biochemical parameters and hematological parameters remain constant after administration of the plant aqueous extract. A dosage of antihyperglycemic activity revealed a reduction of glycemia with a dose of 500 mg/kg. The important results obtained from this study justify the use of this plant in traditional medicine for treatment of diabetes. However, it will be useful to confirm a non-toxic effect of the plant extract through histological dissection of liver and kidney

26. Is Berberine Superior to Metformin in Management of Diabetes Mellitus and its Complications?
Tatyasaheb Patil1*, Snehal Patil2, Anuprita Patil3, Shreedevi Patil
Abstract
Diabetes is a fast growing non infectious disease affecting people of both developed and developing countries across the globe. Treatment of diabetes mellitus requires multisystemic approach to control the disease and prevent complications. Existing oral antidiabetics though potent, exhibit multiple adverse drug reactions and side effects. Berberine would prove to be an effective alternative to these drugs as it offers protection from systemic complications and has minor side effects. This review attempts to compare the efficacy of berberine and metformin as antidiabetic and their role in deterrence of diabetic complications. Berberine scores over metformin as a antidiabetic by certain pharmacological mechanism like alpha glucosidase reductase inhibition, release of GLP 1, modification of gut microbiota, inhibition of enzyme dipeptidyl pepetidase 4 and as a insulin mimetic. Lipid lowering action and effect on polycystic ovarian disease is more superior with berberine than metformin. Thus it can be concluded that berberine can be superior to metformin in management of diabetes and in prevention of its complications.

Abstract
Malaria, the most devastating disease in the tropical region, continue to be the subject of research work by many researchers  because of the increasing resistance of the malaria parasite to antimalarial drugs sold in the market . These researches aim at finding effective curative drugs and especially affordable to the population of which majority are very poor mainly in the developing nations. Our objective also is to discover new active natural compounds effective on Plasmodium falciparum. It consisted of screening for the phytochemical composition of eight plants traditionally used to treat malaria in the Region of Toumodi in central Côte d’Ivoire. These are Anthocleista djalonensis (Loganiaceae), Cochlospermum planchonii (Cochlopermaceae), Harungana madagascariensis (Hipperiacaceae), Hoslundia opposita (Lamiaceae), Mangifera indica (Anacardiaceae), Margaritaria discoidea (Euphorbiaceae), Pericopsis laxiflora (Fabaceae) and Terminalia glaucescens (Combretaceae). Samples consisted of leaves and bark of plant, were harvested, dried and then extracted with solvents of increasing polarity (water, ethanol, and methanol). The obtained powders were subjected to quantitative phytochemicals analysis based on reactions of coloration and precipitation. The results showed that the extraction efficiency varies between 6.3% and 12.1% for the aqueous extract, 8.8% to 20.1% ethanolic extract and 5% to 21.2 % for the methanolic extract. This extraction efficiency is not significantly different from each other whatever the solvent and the plant (P> 0.05). The phytochemical analysis showed that polyphenols are present in 23 of the 24 extracts that is a rate of 95.8%, 95.8% for the alkaloids, 79.2% for the flavonoids, 62.5% for sterols and polyterpenes and 25% saponins and tannins in a small proportion of 16.7% for gallic tannins and 8.3% for catechin tannins. The abundance of chemical compounds of which their pharmacological activities have been shown by other authors, make us to conclude that our plants are very good sources of natural molecules for the fight against malaria and other emerging diseases in our country.

Abstract
The leaves of M. indica are used as a source of mangiferin for the pharmaceutical industry. The present study deals with the phytochemical and physicochemical evaluation of different varieties in order to identify the most suitable one. The parameters included in this comparative study are extractable matter, mangiferin content, water content and total ash. ANOVA revealed a significant difference between the physicochemical parameters of the different cultivars. The Hierarchical Ascendant Classification divided the 29 cultivars into 4 clusters. Eventhough the Filipino and Biscochuelo cultivars showed a higher content of Mangiferin, the cluster of cultivars including the cultivar Corazón is the most suitable one taking the results of the extractable matter into account. In addition, the seasonal variation was investigated for the latter cluster, which revealed that optimal collection period includes the flowering and green fruit stages. Furthermore, based on the investigation of the influence of the drying and storage conditions, plant material for industrial isolation of mangiferin, can be dried using a sun dryer and stored in glass or polypropylene containers for one year.

Maria P. Dimitrova, Nadezhda Tr. Petkova, Panteley P. Denev, Iordanka N. Aleksieva
Abstract
The aim of the current study was to investigate the carbohydrate composition, total phenolic content and in vitro antioxidant activities of 70 % (v/v) ethanol extracts obtained from fruits and leaves of three Morus species: white mulberry (Morus alba), black mulberry (Morus nigra) and red mulberry (Morus rubra) grown in Bulgaria. The carbohydrate content was determinated by spectrophotomeric, TLC and HPLC-RID methods. The total phenolic content was analyzed by Folin–Ciocalteau method. The antioxidant activities of above mentioned extracts were evaluated by DPPH and FRAP assays. From the obtained results, monosaccharides fructose and glucose were found to be the main sugars in all investigated extracts, as their content reached to 3.0 g/100 g fw in fruits and 0.6 g/100g fw in leaves. M. alba and M. rubra fruits were evaluated as a natural source of prebiotic, due to the presence of 1-kestose, nystose and inulin. The absence of sucrose in all mulberry fruit extracts was also established. The total phenolic content was reported to be the highest in black and red mulberry leaves, as their values reached up to 2 mg GAE/g fw. The extracts from M. nigra leaves demonstrated the highest antioxidant activity for both assays: for DPPH were 10.9 mM TE/g fw and for FRAP – 6.0 mM TE/g fw, respectively. The current research was the first comprehensive study for detailed analysis of carbohydrate composition and antioxidant properties of three mulberry species grown in Bulgaria. Therefore, mulberry fruits and leaves could be assumed as a rich source of biologically active substances with great importance for human nutrition
