[Isoprenoids and phenylpropanoids from Saussurea deltoidea].

To investigate the chemical constituents of Saussurea deltoidea, 10 compounds were isolated from the title plant by various chromatography methods such as silica gel, RP-18 silica gel, Sephadex LH-20 column chromatography, HPLC, et al. Their structures were elucidated by spectral analysis. Five isoprenoids and Five phenylpropanoids were isolated and elucidated as (3R, 6R, 7E) -3-hydroxy-4, 7-megastigmadien-9-one (1), (3S, 5R, 6S, 7E) -5, 6-epoxy-3-hydroxy-7-megastigmen-9-one (2), 3-hydroxy-beta-damascone (3), S-(+) -dehydrovomifoliol (4), megastigman-5-ene-3beta, 9R-diol (5), coniferaldehyde (6), beta-hydroxypropiovanillone (7), 3-hydroxy-1-(4-hydroxy-3, 5-dimethoxyphenyl) -1-propanone (8), dihydrosyringenin (9), 4-[(1S) -3-hydroxy-1-methoxypropyl]-2, 6-dimenthoxyphenol (10). All the compounds were isolated from S. deltoidea for the first time.
