Abstract:
Objective To study the chemical constituents from Bletilla ochracea. Methods The compounds were extracted by 95％ alcohol and isolated by column chromatography on silica gel and Sephadex LH-20. Their structures were identified by spectroscopic analysis (～1 H NMR and 13 CNMR).Results Nine compouds were obtained and identified as lusianthridin (1), 1, 2, 7-trihydroxy-4-methoxy-9, 10-dihydroxyphenanthrene (2), nudol (3), coelonin (4), batatasin Ⅲ (5), 3, 7-dihydroxy-2, 4-dimethoxyphenanthrene (6), daucosterol (7), β-sitosterol (8), stigmasterol (9).Conclus ion Compounds 2, 3, 5 were isolated from this plant for the first time.
