Two new triterpenoids from the carpophore of Xanthoceras sorbifolia Bunge.

Two new triterpenoids 3-O-beta-d-glucopyranosyl (1-->6)-beta-d-glucopyranosyl, 28-O-beta-d-glucopyranosyl (1-->6) [alpha-l-rhamnopyranosyl (1-->2)]-beta-d-glucopyranosyl, 16-deoxybarringtogenol C (1) and 22-O-acetyl-21-O-(4'-O-angeloyl)-beta-d-fucopyranosyl theasapogenol B (2), were isolated from the dried carpophore of Xanthoceras sorbifolia Bunge (Sapindaceae). 1 and 2 were found to have activity of inhibiting the proliferation of two human tumor cell lines.
