title: Tetranortriterpenoids from Chisocheton paniculatus.
abstract: Seven new tetranortriterpenoids (1-7), named chisonimbolinins A-G, were isolated from twigs of Chisocheton paniculatus. Their structures were elucidated on the basis of extensive spectroscopic analyses, and the structure of 1 was confirmed by a single-crystal X-ray diffraction study. Cytotoxic activity of compounds 1-7 was evaluated using HeLa and SMMC-7721 tumor cell lines.
