Chemical constituents from Trichosanthes kirilowii Maxim.

Abstract The present phytochemical investigation on Trichosanthe s kirilowii led to the isolations of 17 compounds, including terpenoids, sterols, flavonoids, saccharide derivatives and alkaloids. In this study compounds ( 10 – 11 ), ( 1 – 2 , 13 ) and ( 8 – 9 , 12 , 15 – 17 ) were isolated for the first time from T. kirilowii , the genera Trichosanthe s, the family Cucurbitaceae respectively. The found of compounds ( 1 – 6 and 13 ) indicate a close relationship among the four genera Cucumis , Luffa , Cucurbita and Trichosanthes , which may be as chemotaxonomic markers for the family Cucurbitaceae. The presences of compounds ( 8 , 9 ) might be employed as the common characteristic constituents of both Cucurbitaceae and Rutaceae families.
