黄桐树皮的化学成分研究

Chemical Constituents from Barks of Endospermum chinensis Benth

摘要:

从黄桐树皮中分离获得了10个化合物。通过光谱分析，分别鉴定为3-羰基齐墩果酸（1）、齐墩果酸（2）、7-羰基谷甾醇（3）、β-谷甾醇（4）、β-胡萝卜甙（5）、7-羰基-β-胡萝卜甙（6）、4-羟基-3-甲氧基苯甲醛（7）、7-羟基-6-甲氧基香豆素（8）、2-羟基-4-甲氧基苯甲酸（9）和壬二酸（10）。10个化合物均为首次从黄桐树皮中分离得到。

Abstract:

Ten chemical constituents were isolated from the barks of Endospermum chinensis Benth. On the basis of spectral data, they were identified as 3-oxo-12-oleanen-28-oic acid (1), oleanolic acid (2), 7-oxo-β-sitosterol (3), β-sitosterol (4), β-daucosterol (5), 7-ketone-β-daucosterol (6), 4-hydroxy-3-methoxybenzaldehyde (7), scopoletin (8), 2-hydroxy-4-methoxybenzoic acid (9) and nonanedioic acid (10). All these compounds were obtained from the species for the first time.
