Abstract
A new noroleanane named as karounitriol (1), together with four known compounds, 7-oxodihydrokarounidiol (2), isokarounidiol (3), karounidiol (4), and stigmasta-7,22-dien-3β-ol were isolated from the seeds of Trichosanthes kirilowii Maxim. Structure of the new compound was elucidated as 3α,7β,29-trihydroxy-D:C-friedo-olean-8-ene on the basis of spectroscopic methods including extensive 1D NMR (1H, 13C), 2D NMR (1H-1H COSY, DEPT, HMQC, HMBC, and NOESY), IR, and MS studies.
