| Abstract : Universiti Pendidikan Sultan Idris |
| The chemistry of Piper species has been widely investigated and phytochemical investigations conducted in all parts of the world have led to the isolation of a number of physiologically active compounds. Thus, this study was carried out to investigate the phytochemicals from Piper magnibaccum from Malaysia. Fractionation and purification of the leaves led to the isolation and identification of linoleic acid (1), 24S-ethylcholesta-5,22,25-trien-3β-ol (2), oleic acid (3), β-sitosterol (4), cepharadione A (5), piperumbellactam A (6), and stigmast-3,6-dione (7). The structures of these compounds were obtained by analysis of their spectroscopic data, as well as the comparison with that of reported data |
