ABSTRACT
Objective: To study the chemical constituents from Stelleropsis tianschanica. Methods: The constituents were isolated from S. tianschanica and purified by column chromatography, and the structures were identified by spectral analysis and chemical methods. Results: A total of 12 compounds were isolated from S. tianschanica, including seven flavonoids compounds, two lignans compounds, and the other three compounds, and the structures were identified as wikstrol A (1), wikstrol B (2), viburnolide A (3), genkwanol B (4), genkwanol C (5), stelleranol (6), dipropyl phthalate (7), diisobutyl phthalate (8), 1,3,5-triol-2-methoxybenzene (9), coniferin (10), syringin (11), and acacetin (12). Conclusion: Compounds 1-2, 5-6, 9-12 are isolated from the genus Stelleropsis for the first time.
ABSTRACT
Objective: To further study the chemical constituents of Stelleropsis tianschanica. Methods: The constituents were isolated and purified by silica gel chromatography repeatedly, and the structures were identified by spectra analysis and chemical methods. Results: Twelve compounds including five lignans and three diphenylpentane derivatives were obtained, and named as kusunokinin (1), pluviatolide (2), dibutyl phthalate (3), dipropyl phtalate (4), p-dihydroxybenzene (5), daphneolon (6), 2(S)- hydroxy-1-(4-hydroxy phenyl)-5-phenyl-1-pentanone (7), (2R,3R)-1,5-diphenylpentane-2,3-diol (8). lariciresinol (9), isolariciresinol (10), matairesinol (11), and 4α,5βH-guai-9,7(11)-dien-12,8-olide-12,8α-diol (12). Conclusion: Compounds 1-12 are all obtained from the plant of S. tianschanica and the genus Stelleropsis Pobed. for the first time.
ABSTRACT
Objective: To study the chemical constituents from the arerial parts of Stelleropsis tianschanica. Methods: The constituents were isolated and purified by silica gel chromatography repeatedly, and the structures were identified by spectra analysis and chemical methods. Results: Thirteen compounds were isolated from S. tianschanica and the structures were identified as (+)-pinoresinol (1), (-)-pinoresinol (2), 3'-desmethylarctigenin (3), arctigenin (4), pluviatolide (5), umbelliferone (6), 4-(3,4- dimethoxybenzyl)-3-(4-hydroxy-3-methoxybenzyl)-tetrahydrofuran-2-ol (7), daphnogitin (8), daphnetone (9), blumenol B (10), loliolide (11), 4'-hydroxyacetophenone (12), and 4'-hydroxybenzoic acid (13). Conclusion: Compounds 1-13 were all obtained for the first time from the plant of S. tianschanica and the genus Stelleropsis Pobed.
