Chemical constituents in root bark of Torricellia angulata var. intermedia (III) / 中草药

ABSTRACT

Objective: To investigate the chemical constituents in the root bark of Torricellia angulata var. intermedia. Methods: The compounds were isolated by means of column chromatography on silica gel, macroporous resin, Sephadex LH-20, and ODS, and their structures were elucidated by physicochemical properties and spectra. Results: Ten compounds were obtained and identified as syringaresinol (1), stigmasterol (2), 3,4,5,7-tetrahydroxy benzeneacetic acid (3), stigmasta-5,11-dien-3β-ol (4), 22,23-dihydrostigmasterol (5), β-daucosterol (6), 26,27-dinor-4,4-dimethyl-cholesta-8,14-dien-3-ol (7), octadecanoic acid (8), palmitic acid (9), and 4-hydroxy-3,5-dimethoxyl benzaldehyde (10). Conclusion: Compound 3 is isolated from natural plant for the first time and compounds 1, 2, 4, 5,7, and 10 are isolated from this plant for the first time.
