Tahira Foyzun, Koly Aktar, Mohammad Ashraf Uddin
Abstract
The aim of present study was to evaluate antioxidant, cytotoxic and antimicrobial activities of methanolic extracts of pulp and seed of Phyllanthus acidus. The antioxidant potential were evaluated in terms of total phenolic content, total flavonoid content and DPPH radical scavenging potential by specific standard procedures. Maximum phenolic (25.672± 0.645 mg gallic acid equivalents/mg of plant extract) and flavonoid (13.893 ± 0.320 mg catechin equivalents/mg of plant extract) contents were found in pulp extract than seed extract. Both the pulp and seed extracts showed the potent antioxidant activity with IC50 value of 5.96 µg and 6.79 µg/mL respectively which are very close to the IC50 value of standard ascorbic acid having 2.16 µg/mL). The cytotoxic activity was evaluated by using brine shrimp lethality bioassay and compared with vincristine sulfate as standard. The cytotoxicity exhibited by both extract was promising with LC50 value of pulp and seed were 6.25 µg/mL and 6.7925 µg/mL respectively comparing with the LC50 value 0.4687525 µg/mL of standard vincristine sulphate as a positive control. Furthermore, the extracts were examined for antimicrobial activity against a panel of microorganisms where both the extracts CMEP and CMES showed mild to moderate antimicrobial activity. Moreover, CMEP have exhibited highest zone of inhibition which was 12mm against Pseudomonous aeruginosa. The results suggest into the plant extracts could be used as a potential therapeutics in many pathological conditions.

Z Benouadah, N Mahdeb, A Bouzidi
Abstract
Datura stramonium L. or jimson weed is a wild shrub which belongs to Solanaceae family. It contains a number of toxic alkaloids such as atropine, hyoscamine and scopolamine. The objective of this study was to evaluate the acute and sub-acute toxicity of alkaloids extracted from the seed of Datura stramonium sp. In mice. Biochemical, hemodynamic, histological parameters were investigated. Experiments on acute toxicity on alkaloids, injected intraperitoneally, showed that these substances are moderately toxic (lethal dose 50 %: 303.4 mg/kg). The resulting intoxication triggered tachycardia, difficulty in breathing, convulsions and a decrease in locomotor activity in mice. The acute treatment for 24 hours and 5 days at a dose of 1/5 LD50, i.e., 60 mg/kg of alkaloids, did not show any difference in body weight. There was an increase in heart beat and respiratory cycle on day 1 in injected mice compared to control animals. These parameters became normal after 5 days of treatment. The hematological observations show that alkaloids at a dose of 60mg/kg induced a significant decline in the number of red blood cells (RBC), hemoglobin and hematocrit. The plasma AST, ALT, LDH, K+, urea and creatinine levels were significantly affected after alkaloid administration. The sub-acute dose (16 mg/kg) after 28 days resulted in a significant increase in AST, ALT, GGT, PLA, Na+ and K+ concentrations accompanied by a significant decrease in RBC, hemoglobin, hematocrit and platelets levels. Heart beat and respiratory cycle also increased in treated-animals compared to the controls. Histopathological examination revealed high degree of vacuolization and inflammation in liver and the same up to lesser extent in kidney. In conclusion, the Datura stramonium. sp alkaloids modulate biochemical, hematological and histological parameters in mice.

Yele S U, Veeranjaneyulu A

Abstract
In recent years there has been a renewed interest to screen plant extracts, juices, combinations of two or more plant drugs for a possible beneficial uses in diabetes. Momordica charantia (MC) commonly known as karela and Eugenia jombolina (EJ), have been reported to have antiviral, antidiabetic, antitumor activities etc. The inhibitory effects of aqueous fruit extract of MC and aqueous stem bark extract of EJ on the transport of d-glucose, l-tyrosine was studied across rat-everted intestine in vitro. Krebs–Henseleit bicarbonate buffer was used as mucosal medium to incubate the gut sacs. Increasing concentrations (1.5–12 mg/ml) of MC and EJ extract were incubated in the mucosal solution. The serosal appearance and mucosal disappearance of d-glucose and l-tyrosine were significantly inhibited with increasing concentrations of MC, EJ bark extracts and their combination (50:50). The aqueous extracts of the selected plants were found to inhibit primarily the uptake of glucose in a dose-dependent manner and uptake of tyrosine was affected only at higher concentration of extract especially in case of MC. Most importantly, the study has shown inhibition of the active transport of d-glucose, l tyrosine across rat intestine which may be effect of saponins and tannins in MC extract and EJ stem bark extract respectively. Results demonstrate tolerability and efficacy of herbal combinations of two plants that seem to act differently but synergistically to regulate glucose-homeostasis.

Sahu R A, Itankar P R, Mishra R R, Maliye A N
Abstract
Astavarga group have a long history of use in traditional system of indigenous medicine. It is used in chyawanprash as a rejuvenator and health motivator. However, no systematic & scientific data is available to validate the claim. Hence, immunomodulatory activities of Roscea procera (kakoli) and Lilium polyphyllum (kshirkakoli) plants were studied on mice for haematological parameters, delayed type hypersensitive reaction and lymphoid organ weighing. There was significant modulation of immune reactivity in all the three animal models. Treatment with ethanol extract of kakoli and ethyl acetate extract of kshirkakoli (200 mg/kg of b.w.) was found to enhance WBC count (p<0.001 & p<0.01 respectively) and weight of thymus and spleen. Ethanolic extract of kakoli was accompanied by significant increase in delayed type hypersensitive reaction. In conclusion increase in immunomodulaory potential of EEK and EAEKS over the other extracts could be due to partial purification and separation achieved by successive extraction procedure which might result in increase in degree of polymerization and segregation of secondary metabolites such as alkaloids, flavonoids, steroids etc. in extracts showing highest activity.

Amise A F, Lennox J A, Agbo B E
Abstract
The antimicrobial potential and phytochemical analysis of Dacryodes edulis (African pear) was investigated using standard microbiological procedures. Phytochemical screening of the raw and boiled African pear seed and mesocarp showed the presence of glycosides, tanins, flavonoids, saponins, reducing compounds, alkaloids and polyphenol in their ethanol extracts while the absence of saponins, tanins and alkaloids was observed in aqueous extracts of both the raw and boiled African pear seed and mesocarp. The aqueous and ethanolic extracts of both the African pear seed and pulp at varying concentrations of 1g/10ml, 2g/10ml, 4g/10ml, 5g/10ml was tested against some selected human pathogens such as Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus vulgaris, Staphylococcus aureus and Enterococcus faecalis. The results of the ethanol extracts of the African pear seed showed marginally higher zones of inhibition against the clinical bacterial isolates tested. The organisms were resistant to the aqueous extracts of both the African pear pulp and seed. The African pear seed ethanol extracts showed a higher zone of inhibition of 21mm against Klebsiella pneumoniae and 18mm against Proteus vulgaris as compared to 18mm against Klebsiella pneumoniae and 17mm against Proteus vulgaris by Gentamycin used as standard antibiotic control. However, African pear (Dacryodes edulis) can be of immense benefit to pharmaceutical industries for the development of new antimicrobial drugs.

16. Proteus species: Characterization and Herbal Antibacterial: A Review
Ghaidaa Jihadi Mohammed, Mohanad Jawad Kadhim, Imad Hadi Hameed
Abstract
Plants are rich source of antibacterial agents because they produce wide array of bioactive molecules, most of which probably evolved as chemical defense against predation or infection. A major part of the total population in developing countries still uses traditional folk medicine obtained from plant resources with an estimation of WHO that as many as 80% of world population living in rural areas rely on herbal traditional medicines as their primary health care, the study on properties and uses of medicinal plants are getting growing interests. In recent years this interest to evaluate plants possessing antibacterial activity for various diseases is growing. Proteus spp. are part of the human intestinal flora and can cause infection upon leaving this location. They may also be transmitted through contaminated catheters (particularly urinary catheters) or by accidental parenteral inoculation. The specific mode of transmission, however, has not been identified. Antimicrobials of plant origin have enormous therapeutic potential and have been used since time immemorial. They have been proved effective in the treatment of infectious diseases simultaneously mitigating many of the side effects which are often associated with synthetic antibiotics. Many infectious diseases have been known to be treated with herbal remedies based on ethno-botanical knowledge. Natural products, either as pure compounds or as standardized plant extracts, provide unlimited opportunities for new drug leads because of the unmatched availability of chemical diversity. Therefore, researchers are increasingly turning their attention to folk medicine, looking for new leads to develop better drugs against microbial infections. Thus, it is anticipated that phytochemicals with adequate antibacterial efficacy will be used for the treatment of bacterial infections. The present antibacterial review of the plant extracts demonstrates that folk medicine can be as effective as modern medicine to combat pathogenic microorganisms. The millenarian use of these plants in folk medicine suggests that they represent an economic and safe alternative to treat infectious diseases.

Amir Siahpoosh, Amir-Mehdi Taleb, Hanieh Almasi
Abstract
This study was aimed at evaluating polyphenolic compounds and antioxidative capacity of Berhi variety of Date as well as comparing the methanolic extract and methanol-chloroform and methanol-aqueous fractions. The methanolic extract was prepared by maceration method. Concentratrd methanolic extract was suspended in water and extracted by chlorophorm. Water and chlorophorm fractions were dried with freeze drier. In this paper, the antioxidant activity of extracts has been analyzed using DPPH (1,1-diphenyl-2-picrylhydrazyl), ABTS (2,2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) free-radical scavenging, FRAP (ferric reducing antioxidant power), Iron chelation and erythrocyte hemolysis assays. In addition total phenolic, flavonoids and oligomeric proanthocyanidins compounds were also analyzed. Quantitative phytochemical studies showed the presence abundant amount of phenolic, flavonoids and oligomeric proanthocyanidins compounds in extracts. The IC50 values of, Met-Aqu, methanolic and Met-Chl extracts for scavenging the DPPH and ABTS radical ranged from 161.64 to 238.95 and 52.3 to 152.40, respectively while that of Iron chelation, erythrocyte hemolysis and EC1 of FRAP assay ranged from 695.38 to 925.94, 147.40 to 418.87 and 0.748 to 2.32 µg/ml.  Results indicate that the amount of total phenol, flavonoids and oligomeric proanthocyanidins compounds in the extracts is rated as Met-Aqu> Methanol>Met-Chl. Results of antioxdative, iron chelation, and hemolysis tests indicate an order of Met-Aqu> Methanol>Met-Chl. Better results of Met-Aqu can be because of its more polyphenolic compound. Results above show that this method of preparing fractions from methanolic extract can cause more polyphenolic compound extraction and improvement of the antioxidative effect.

19. Anti-Microbial, Anti-Inflammatory and HIV-1 Reverse Transcriptase Activity of Selected South African Plants used to Treat Sexually Transmitted Diseases
Mamba P, Adebayo S A, Tshikalange T E
Abstract
The purpose of the study was to investigate the bioactivity of extracts of selected plant species used to treat sexually transmitted diseases (STD’s) in southern Africa. As the emergence of drug resistance pathogens in STD’s treatment and potential side effects of synthetic drugs demands the discovery of newer and safer drugs, the exploration of newer anti-microbial substances from natural sources may serve as promising alternatives. Ethanol extracts of twelve medicinal plants used traditionally to treat sexually transmitted diseases and 3 flavonoids (F1, F2 and F3) isolated from Elaeodendron transvaalense were evaluated for their antimicrobial properties against one fungus and three bacteria. To determined anti-inflammatory activities of the extracts and compounds, the inhibitory effect was measured on the pro-inflammatory enzyme, 15-lipoxygenase (15-LOX). The extracts and compounds were also investigated for their anti-HIV activity against recombinant HIV-1 enzyme using non-radioactive HIV-RT colorimetric assay. Acacia karoo and Rhoicissus tridentata extracts indicated good anti-microbial activity with MIC values ranging between 0.4 and 3.1 mg/mL. Extracts of Jasminum fluminense, Solanum tomentosum, F2 and F3 had good anti-inflammatory activity with IC50 less than positive control quercetin (IC50 = 48.86 µg/mL). Acacia karoo and F3 exhibited moderate HIV RT inhibition activity of 66.8 and 63.7% respectively. Rhoicissus tridentata and Terminalia sericea had the best RT inhibition activity (75.7 and 100%) compared to that of the positive control doxorubicin (96.5%) at 100 µg/mL. The observed activities may lead to new multi-target drug against sexually transmitted diseases.

Abstract
Context: The World Health Organization reported that more than 1 million sexually transmitted infections (STIs) are acquired daily, with an estimated 357 million new infections caused by either chlamydia, gonorrhoea, syphilis or trichomoniasis. Aim: The present study was aimed to evaluate antimicrobial, antioxidant and cytotoxicity activities of ethanol extracts of ten ethnobotanical selected plant species used to treat STD’s and related symptoms. Methods: The determination of antimicrobial susceptibility of plant extracts was done using the broth micro-dilution assay against five microorganisms. The free radical scavenging activity was determined by using DPPH (2, 2-diphenyly-1-picrylhydrazyl). Cytotoxicity activity of the plant extracts was done on Vero African monkey cells lines with 2, 3-bis [2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide (XTT) reagents. Results: Our results suggest that extracts of Acacia karroo and Rhoicissus tridentata subsp. cuneifolia are potential candidates with a good antimicrobial, antioxidant and low cytotoxicity activities. This results may support the anecdotal claims for the use of the selected plant species to treat venereal diseases.
