Abstract

A new nortriterpene, 2‐hydroxy‐3‐methyl‐21‐oxo‐12,24‐dinor‐D : B‐friedooleana‐1,3,5(10),7‐tetraen‐29‐oic acid (1), was isolated from the root of Celastrus hypoleucus, together with the two known compounds, celastorol (2) and pristimerine (3). Their structures were elucidated on the basis of spectroscopic analyses. Compounds 1–3 exhibited in vitro significant antioxidant (against lipid peroxidation; by the TBARS method) and antitumor activities (against cancer cell lines P‐388, A‐549, HL‐60, and BEL‐7402).
