目的:研究八角科八角属小花八角的化学成分。方法:通过多种色谱方法分离化合物,通过波谱方法确定其结构。结果:从小花八角中分离并鉴定了9个化合物,分别是β-谷甾醇(1),槲皮素(2),芦丁(3),槲皮素-3-O-α-L-鼠李糖苷(4),厚朴酚(5),dictagymnin(6),(+)-syringaresinol(7),(+)-diaeudesmin(8)和没食子酸(9)。结论:化合物4～9为首次从该植物中分离得到。 Objective: To study the chemical composition of star anise Methods: Compounds were isolated by a variety of chromatographic methods and their structures determined by spectroscopic methods. RESULTS: Nine compounds were isolated and identified from Betula oculata, which were β-sitosterol (1), quercetin (2), rutin (3), quercetin-3-O-α-L- (4), honokiol (5), dictagymnin (6), (+) - syringaresinol (7), (+) - diaeudesmin (8) and gallic acid (9). Conclusion: Compounds 4 ~ 9 were isolated from this plant for the first time.
