title: [Studies on chemical constitutes from callus cultures of Stellera chamaejasme].
abstract: From callus cultures of Stellera chamaejasme, 17 compounds were isolated. Based on their physical and chemical data and spectroscopic analysis, they were identified as syringaresinol (1), medioresinol (2), pinoresinol (3), (1R, 2S, 5R, 6S)- 2-(4- hydroxyphenyl)-6-(3-methoxy-4-hydroxyphenyl)-3, 7-dioxabicyclo [3, 3, 0] octane (4), epipinoresinol (5), caruilignan D (6), 3-oxo-guai-4-ene-11, 12-diol (7), (-) -lariciresinol (8), tetrahydro-2-(4-hydroxy-3-methoxyphenyl)-4-[(4-hydroxyphenyl) methyl]-3-furanmethanol (9), 5'-methoxylariciresinol (10), vladinol D (11), cyclo (L-Pro-L-Val) (12), oxomatairesinol (13), (+) -guayarol (14); acutissimalignan B (15), isolariciresinol (16), and beta-sitosterol (17), respectively. Among these compounds, 12 was a cyclodipeptide, 7 was a sesquiterpene, and the others except 17 were lignans. All compounds were first isolated from callus cultures of S. chamaejasme.
