Phytochemical and Biological investigations of <i>Phoenix paludosa</i> Roxb.
Keywords:Phoenix paludosa, Aracaceae, Lupeol, Epi-Lupeol, ?-sitosterol, Brine shrimp lethality bioassay, Antimicrobial
AbstractLupeol (1), epilupeol (2) and β-sitosterol (3) were isolated from the n-hexane and the carbon
tetrachloride soluble fraction of a methanol extract of the leaves of Phoenix paludosa Roxb. The n-hexane, carbon
tetrachloride and chloroform soluble materials from the concentrated methanol extract were subjected to
antimicrobial screening and brine shrimp lethality bioassay. All of the partitionates showed insensitivity to microbial
growth, while the n-hexane, chloroform and methanol soluble fractions showed significant cytotoxicity having LC50
2.17 μg/ml, 2.77 μg/ml and 2.46 μg/ml, respectively. This is the first report of isolation of the compounds 1-3 and
bioactivities of P. paludosa.
