1. Pharmacological & Phytochemical Evaluation Of Gastric Anti-Ulcer Activity of Parthenium hysterophorus In Different Models
Ananda Kumar. Chettupalli, Vasudha. B, Krishna Sanka
Abstract
The cause of ulceration in patients is mainly due to hyper secretion of gastric juice and also due to hyper secretion of pepsin. In traditional system of medicine a number of herbal preparations have been used for the treatment of peptic ulcers. There are various medicinal plants has been used for the treatment of gastrointestinal disorders. In view of this, in present study we have to evaluate the anti-ulcer activity of parathenium hysterophorus. Study was carried out, by using three methods i.e., alcohol, paracetamol and stress induced ulcers in rats pretreated with the doses of 250 mg/kg AQPH and ALPH, 20mg/kg Omeoprazole and 50 mg/kg Ranitidine. To evaluate the antiulcer activity of aqueous and alcoholic extracts of parathenium hysterophorus leaves (AQPH and ALPH) at 250 doses using different experimentally induced gastric ulcer models in rats. Gastric ulcers were induced in rats by 80% alcohol, paracetamol and forced immersion stress induced methods. In alcohol induced ulcer model, paracetamol induced ulcer model and stress induced model the ulcer index was determined. Where as in stress induced ulcers stress plays an important role in ulcerogenesis. In alcohol-induced ulcers, AQPH and ALPH were effective in reducing lesion index and increasing the gastric mucus content. It was also effective in decreasing ulcer index in paracetamol-induced ulcers. All the results obtained with parathenium hysterophorus were dose dependent.  The results suggest that AQPH and ALPH possesses significant and dose dependent antiulcer activity. The antiulcer activity of AQPH and ALPH can be attributed to its cytoprotective and antisecretory action.

Abstract
The radical scavenging activity of acetone, ethanol and aqueous extracts from Agaricus placomyces, Cantharellus cibarius and Pleurotus ostreatus from the Niger Delta region of Nigeria was determined with their metal chelating and reducing power. The extracts exhibited significant free radical scavenging activities in the DPPH assay (IC50 = 2.11 to 4.37 mg/mL) with the aqueous extract from P. ostreatus being the most potent. Also, the aqueous extracts exhibited better metal chelating abilities and reducing power than the ethanol and acetone extracts. In addition, higher content of total phenolics and flavonoids was found in the aqueous extract of A. placomyces (55.63mg GAE/g) and P. ostreatus (15.55 mgQE/g) respectively, whereas ascorbic acid ranged from 0.33 to 1.22 mgAAE/ in all the extracts. Overall, our results indicate that mushrooms particularly Agaricus placomyces, and Pleurotus ostreatus contain high amount of polyphenolic compounds with significant free radical scavenging abilities,  notable metal chelating activities and promising reducing power. These properties indicate that the mushrooms are functional foods with the potential to attenuate oxidative stress associated with free radical damage in biological systems.

Jigni Mishra, Ankit Tripathi, Kshipra Misra, Sarada S K S
Abstract
Curcumin, an important phytoconstituent obtained from Curcuma longa L. (turmeric) is used traditionally in the treatment of various inflammatory diseases like arthritis, stroke and bowel diseases, etc. Despite its many health benefits, instability of curcumin in plasma is a major issue. The retention of curcumin in plasma must be properly evaluated in order to establish its stability in biological systems. The current study presents an HPTLC method undertaken for detection of curcumin and determination of its stability in plasma and different tissues of rats. The plasma and tissue samples were appropriately processed to render them suitable for HPTLC analysis. The method employed HPTLC glass plates precoated with silica gel 60F254 as the stationary phase. The mobile phase developed consisted of chloroform, methanol and glacial acetic acid which successfully gave distinct bands for curcumin with a Rf value of 0.95. This newly developed HPTLC method was found to be reproducible and accurate in quantifying curcumin in mammalian samples. This method was further utilized to efficiently estimate the time for which curcumin is retained in its native form in mammalian tissues and plasma alike.

Esseid Chahrazed, Hamadou Meriem Hadjer, Ameddah Souad, Ahmed Menad, León Francisco, Brouard Ignacio, Marchioni Eric, Benayache Samir, Benayache Fadila
Abstract
Phytochemical investigation of the n-butanol soluble part of the aqueous-MeOH extract of the aerial parts of Pituranthos battandieri Maire collected from the region of Bechar in the south-west of Algeria, led to the isolation and structural elucidation of mannitol 1, xanthotoxol 2, 8-(6’,7’-dihydroxygeranyloxy)-psoralen 3 and isorhamnetin 3-O-ß-D-glucopyranoside (cacticin) 4. The structures were established by spectral analyses, mainly ESI-HRMS, UV and NMR experiments (1H, 13C, DEPT, COSY, HSQC and HMBC) and comparison with literature data.  All these compounds were described for the first time from this endemic species. The free radical scavenging activity of this extract was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydrogen peroxide (H2O2) scavenging activity models. Antihemolytic property was performed using H2O2 induced red blood cell hemolysis model. Antiperoxidative effect was evaluated using lipid peroxidation-ammonium thiocyanate model. Both DPPH and H2O2 assays indicated antioxidant ability of n-BuOH extract of P. battandieri (BEPB), that were reflected by IC50 values 876.16±7.96 µg/mL and 603.8±71.06 µg/mL, respectively. In addition, the results of the present study clearly indicated that BEPB inhibited rat erythrocytes hemolysis induced by H2O2 in a dose dependent way with IC50 value 782.38±89.97 μg/mL. The inhibition of lipid peroxides generated from linoleic acid was recorded at IC50: 496.04±117.06 µg/mL. The antiperoxidative and the antihemolytic activities of P. battandieri appear as a consequence of synergistic interactions between active constituents among them mannitol 1, the furanocoumarins 2 and 3, and the flavonoid 4.

S Soufane, A. Bouzidi, N Mahdeb, S Krache
Abstract
In this study, we investigated the effects of acute and subacute administration of the methanolic fruit extract of  Citrullus colocynthis (CCT) in male Albino Wistar rats. The acute toxicity study was undertaken firstly to determine the acute median lethal dose (LD50) of the fruit extract. Then, the second step aimed to evaluate its toxic effects when administered at single daily oral dose 440mg/kg (1/3 of the LD50) after one, three, five, seven, ten and fourteen days on liver function indices (AST, ALT, ALP, total proteins), kidney function parameters (uric acid, urea and creatinine), haematological parameters and electrolyte concentrations (Na+, K+, P, Ca+2) using standard methods. The sub-chronic toxicity was undertaken to evaluate the toxic effects of the same extract and the target organs after its oral administration for six weeks (265 mg/kg) to male rats. The median lethal dose (LD50) of the extract was found to be 1311.45 mg/kg. After acute oral administration of the methanolic extract a dose of 440mg/kg (1/3 of the LD50), there were remarked a loss in body weight and a significant reduction in the relative weights of liver, kidney, lungs, spleen and testis of treated rats. The RBC, WBC count, HCT and HGB concentration were also significantly lower in treated groups than control one. The liver enzymes ALT and AST activities were higher for the main treated groups and significantly elevated in the group sacrificed after three days of the treatment. The ALP has enregistered a significant elevation for the majority of the tested groups. The analysis of kidney function parameters revealed a significantly high creatinine levels for all treatment group (exceptely for the group sacrificed after 14 days), a significant increase in urea level for the group sacrificed after three days of treatment with no remarkable changes in uric acid concentrations. Electrolyte concentrations (Na+, K+, Ca+2) were not significantly affected by CCT alcoholic extract, but the levels of PO4 have shown a significant reduction for the main treatment groups. Histo-pathological examination revealed a discreetly congestion in hepatic and renal parenchyma in groups sacrificed after one and five days of treatment. The present study showed that the intake of extract of ripe Citrullus colocynthis fruit induced a characteristic signs of poisoning: diarrhea, ruffled hair, loss in organ weight and feed intake. The effects on the functions of the liver, kidney and bone marrow in rats resulted in alterations in serum AST, ALT and ALP activities, in the levels of total proteins, urea, uric acid, creatinine and electrolytes as well as in organ lesions.

Lima A L A, Pérez A L A L, Sousa J P, Pinheiro L S, Oliveira-Filho A A, Siqueira-Júnir J P, Lima E O
Abstract
Geraniol is a plant-derived monoterpene alcohol that has antifungal effect. The aim of this study was to evaluate the geraniol for antifungal activity against Candida albicans isolates of pediatric clinical importance. The minimum inhibitory concentration (MIC) and the minimum fungicidal concentration (MFC) were determined by the broth microdilution techniques. We also investigated possible geraniol action on cell walls (0.8M sorbitol) and cell membranes (Geraniol to ergosterol binding). For 90% of isolates, the MIC and MFC of the phytochemical was 64 𝜇g/ml. Involvement with the cell wall and ergosterol binding were excluded as possible mechanisms of action. Thus, geraniol showed in vitro antifungal potential against strains of C. albicans, but did not involve action on the cell wall or ergosterol and further study is needed to completely describe its mechanism of action.

The combined antifungal effect were be determined from the Fraction Inhibitory Concentration index – checkerboard technique. The results obtained in this study showed that eugenol in combination with amphotericin B had antagonistic effect against the strains of C. neoformans, LM 615 and INCQS 40221 (FIC index 6.0 and 4.0), respectively. The combination of the isoeugenol and amphotericin B also showed antagonistic effects for both the LM 615 strain and INCQS 40221 (FIC index 6.0 and 5.0), respectively. This study contributed to the understanding of the antifungal effects of the association of phenylpropanoids (eugenol / isoeugenol) with amphotericin B. Further studies are needed to evaluate and compare the effects of the association of these phytochemicals with other conventional antifungal drugs used against C. neoformans.

Abstract
Some of the plant species of the genus Salacia are considered as an important anti-diabetic drug in ayurveda. Among them S. chinensis, S. fruticosa and S. oblonga possess great medicinal importance, mostly because of its promising anti-diabetic activity. The increasing demand of this drug, resulted in a huge decline in its availability and it is replaced by spurious ones mainly because of lack of adequate quality standards. There is now a felt need to develop a systematic approach for the authentication of these plants and to develop well-designed methodologies for its standardization. The present study focused on the Pharmacopoeial parameters like pharmacognostical characterization and preliminary phytochemical screening of these three species. which were found to be sufficient to evaluate the raw material and can also be used as reference standards for the quality control/quality assurance purposes. The pharmacognostic study revealed that there are specific diagnostic features for distinguishing these three species among themselves and also from other related species. The external morphology of these three species are also shows variation in their colour, odour and taste. Both the species of Salacia ie, S. chinensis is having bitter taste and S. fruticose is with astringent taste whereas S. oblonga has no characteristic taste of its own. The TLC profile showed similar pattern in S. chinensis and S. fruiticosa  where as S. oblonga showed more band in the profile than that of the other two. This reveals that the S. chinensis and S. fruiticosa having similar compounds responsible for therapeutic efficacy, whereas S. oblonga has more chemical constituents.
