ABSTRACT
Functional and health endorsing benefits of various foods are often attributed to their phytochemistry. The bitter gourd holds potential in improving the health of the individuals owing to its incredible versatility in phytochemistry. However, the efficacy of different parts of bitter gourd needs attention of the researchers. In the current exploration, different parts of bitter gourd were evaluated for their cholesterol lowering potential in cholesterol fed Sprague dawley rats. For the purpose, four types of bitter gourd part i.e. whole fruit, seedless fruit, seeds, and seed extracts were used and compared with placebo in hypercholesterolemic rats. In placebo, momentous increase in serum cholesterol, triglycerides and LDL levels was observed. All parts attenuate the cholesterol 18.79 to 40.17% triglycerides 25.97 to 37.01% and LDL 14.49 to 26.09%. However, 1% extract powder was most effective in reducing the cholesterol and triglycerides. From the present study, it is deduced that bitter gourd extract can be supplemented in food products for the management of hypercholesterolemia. However, future studies in human subjects needs to be conducted for meticulousness of the present findings
ABSTRACT
Objective: To investigate the in vitro antimicrobial activities of the leaf extract in different solvents viz., methanol, ethanol and water extracts of the selected plant Ricinus communis. Methods:Agar well diffusion method and agar tube dilution method were carried out to perform the antibacterial and antifungal activity of methanol, ethanol and aqueous extracts. Results:Methanol leaf extracts were found to be more active against Gram positive bacteria (Bacillus subtilis: ATCC 6059 and Staphylococcus aureus: ATCC 6538) as well as Gram negative bacteria (Pseudomonas aeruginosa: ATCC 7221 and Klebsiella pneumoniae) than ethanol and aqueous leaf extracts. Antifungal activity of methanol and aqueous leaf extracts were also carried out against selected fungal strains as Aspergillus fumigatus and Aspergillus flavus. Methanolic as well as aqueous leaf extracts of Ricinus communis were effective in inhibiting the fungal growth. Conclusions: The efficient antibacterial and antifungal activity of Ricinus communis from the present investigation revealed that the methanol leaf extracts of the selected plant have significant potential to inhibit the growth of pathogenic bacterial and fungal strains than ethanol and aqueous leaf extracts.
