Screening of phytochemical and antibacterial activity of Hemidesmus indicus (L.) and Vetiveria zizanoides (L.)

Ratha, M, Subha. K, Senthilkumar. G and Panneerselvam.A

The screening and study of selected Indian medicinal plants Hemidesmus indicus (L.) and Vetiveria zizanoides (L.) were selected for phytochemical screening and antibacterial studies. The solvents used for the extraction of plant roots were ethanol,methanol and distilled water. The invitro antibacterial activity was performed by agar well diffusion method. The most susceptible Gram-Postive and Gram-negative bacteria were tested. The extracts of plant Hemidesmus indicus (L.) and Vetiveria zizanoides (L.) inhibited the growth of the bacterial strains investigated. The most active extracts were compared with the standard antibiotics, penicillin, Streptomycin and Ampicillin 100mg/disc). The results obtained in the present study suggest that preliminary phytochemical analysis detected the presence of Alkaloids, Aminoacid, Flavonoids Saponins and Tanins. The Hemidesmus indicus (L.) and Vetiveria zizanoides (L.) could be used in treating diseases caused by the test organisms. The results are discussed in detail.
