title: [Chemical constituents from Sinacalia davidii].
abstract: Sinacalia davidii (Franch) Koyama. grows only in China, its chemical constituents have never been studied before. The compounds were isolated by column chromatography on silica gel and Sephadex LH-20, and the structures were identified on spectroscopic data (MS, 1H-NMR, 13C-NMR). Six compounds were isolated from S. davidii, and were characterized as p-sitosterol (1), 3-oxo-2alpha, 23-dihydroxy-olean-12-en-28-oic acid (2), 28-hydroxy-olean-12-en-3, 11-dione (3), 3beta-methoxy-olean-11-oxo-18-ene (4), luteolin (5) and 2alpha-hydroxy-ursolic acid (6). All the six compounds above were isolated from S. davidii for the first time.
