Ethnopharmacological investigation and antibacterial evaluation of the methanolic extract of Asparagus racemosus (Shatavari)
T. Kumaran* and T. Citarasu
Abstract:
Plants are the base of sophisticated traditional medicine systems including Ayurvedic, Unani and Siddha. Phytochemical analysis of Asparagus racemosus revealed that numerous compounds of plants traditionally used for medicinal purposes have several therapeutical properties. The result of the phytochemical studies revealed the presence of saponins, tannins, alkaloids, steroids and other biochemicals. Saponins, tannins and alkaloids are well known for their antibacterial properties. Experiments demonstrating the pharmacological properties of saponins have aroused considerable clinical interest in these substances. The concentrations of the plant used were 25 mg ml-1, 50 mg ml-1 and 100 mg ml-1 respectively. At these concentrations, the extract inhibited the growth of Escherichia coli, Pseudomonas aeruginosa and Vibrio parahaemolyticus and produced percentage inhibition ranging from 72.4–86.5 %. The anti-bacterial activity demonstrated by the plant extract may due to the presence of the phytochemicals present in the plant.
