Antimicrobial activities of hexacosane isolated from Sanseveria liberica (Gerome and Labroy) plant

Abstract

The antimicrobial activity of hexacosane isolated from Sansevieria liberica was determined using standard method. The compound was isolated by directing the fractionation of ethyl acetate extract of the air dried root with microbial sensitivity test. The results of antimicrobial test showed moderately high activities against all the test microbes with the compound having zone inhibition of 29, 27, 26 and 25 cm against Klebsiela pnemoniae, Salmonela typhi, Mithecithinne staphaureus and Proteus vulgaris respectively. The structure of the compound was identified from ¹³C-NMR, ¹HNMR, IR and GC-MS spectral data. The isolation, structural elucidation, NMR spectral assignment and bioactivities are reported.

Keywords: Sansevieria liberica, antimicrobial activity, structural elucidation.
