| description |
This work was aimed at isolating and characterizing the bioactive constituents from the crude methanol extract of the whole plant of Phaulopsis barteri. The crude extract which was subjected to a silica gel column chromatography separation using petroleum ether/ethyl acetate blend, eluted a white crystalline substance with a melting point of 215-2160C. PBA shows recognizable peak at 79.02ppm which is characteristic of a carbon carrying an oxygen and the 1HNMR spectrum which shows an olefinic proton at δ 4.71 and 4.56 respectively was identified as lupeol which is a C30H50O moiety. Identification of the compound was purely by spectral analysis.
