The present study was conducted to test for in vivo Brine Shrimp Lethality Assay (BSLA) of the Aqueous and ethanolic extracts of Annona reticulata with Allium fistolisum and Brassica oleraceaeand correlate cytotoxicity results with known pharmacological activities of the plants. Cytotoxicity was evaluated in terms of LC50 (lethality concentration). Ten nauplii were added into three replicates of each concentration of the plant extract. After 24 h the surviving brine shrimp larvae were counted and LC50 was assessed. Results showed that the extracts of Annona reticulata with Allium fistolisumand Brassica oleraceaewere potent against the brine shrimp when compared alone with combined extracts. It indicated that bioactive components are present in these plants that could be accounted for its pharmacological effects. Thus, the results support the uses of these plant species in traditional medicine.

Alcohol abuse and its medical and social consequences are a major health problem in many areas of the world. The present study was conducted to evaluate the protective effect of methanolic fruit extract of Randia dumetorum (L.) on alcohol-induced liver damage in rats. Rats were divided into five different groups (n=6), group I served as a control, group II received ethanol (3 ml/100 g/day p.o.), group III served as standard group and received silymarin (50 mg/kg p.o.), group IV and V served as extract treatment groups and received 50 & 100 mg/kg methanolic extract of R. dumetorum. All the treatment protocols followed 30 days and after rats were sacrificed blood and liver were used for biochemical and histological studies, respectively. The activities serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), direct bilirubin (DB), total bilirubin (TB) and lipid peroxidation were statistically increased in rats exposed to alcohol while total protein and glutathione decreased compared to control rats. Treatment with R. dumetorum significantly decreased the elevated levels of ALT, AST, TG, DB, TB and lipid peroxidation compared to the group exposed to alcohol only. R. dumetorum significantly resulted in increased levels of total protein and reduced glutathione compared to the group that received alcohol only. Histology of the liver section of the animals treated with R. dumetorum improved the hepatotoxicity caused by alcohol. Hence the study concluded that R. dumetorum has potential hepatoprotective activity.

Medicinal plants are in rich source of antimicrobial agents. The present study was carriedout to evaluate the antimicrobial effect of plants from the same species as Brassica oleceraceanamely, white cabbage and red cabbage. The preliminary phytochemical analysis was tested byusing a different extract of these plants for the presence of various secondary metabolites likealkaloids, flavonoids, tannins, saponins, terpenoids, glycosides, steroids, carbohydrates, and aminoacids. The in vitro antimicrobial activity was screened against clinical isolates viz gram positivebacteria Staphylococcus aureus, Streptococcus pyogenes, gram negative bacteria Escherichia coli,Pseudomonas aeruginosa. Extracts found significant inhibition against all the pathogens.
