Bycomprehensive use of phytochemical isolation methods, 37 compounds were isolated 5from the methnol-chloroform extract of P. telfairia, by methods of modern spectroscopy,six compounds' structures were elucidated, including 2 kinds of fatty acids, 2 kinds ofsterols and 2 kinds of are esters of sterol and fatty acids. Five of them were reported forthe first time on the chemical constituents' research of P. telfairia. Otherwise, weperformed GC-MS analysis of the volatile fraction in this extracts, the result revealedseveral constituents such as alkyl hydrocarbons and methyl esters of fatty acids.
