桂木茎枝化学成分的研究

Chemical Constituents from Stems of Artocarpus nitidus subsp. Lingnanensis

摘要:

从桂木(Artocarpus nitidus subsp. lingnanensis)茎枝中分离得到13 个化合物。通过波谱分析,分别鉴定为albanin A (1)、brosimone I (2)、cycloartocarpin A (3)、artotonkin (4)、albafuran A (5)、artocarpin (6)、artogomezianone (7)、β-香树素乙酯 (8)、3,4-二羟基苯甲醛 (9)、3,4-二羟基苯甲酸 (10)、3-甲氧基-1,2-丙二醇 (11)、β-谷甾醇 (12) 和β-胡萝卜苷 (13)。这些化合物为首次从桂木中分离得到。

Abstract:

Thirteen compounds were isolated from stems of Artocarpus nitidus subsp. lingnanensis. On the basis of the spectral data, they were identified as albanin A (1), brosimone I (2), cycloartocarpin A (3), artotonkin (4), albafuran A (5), artocarpin (6), artogomezianone (7), β-amyrin acetate (8), 3,4-dihydroxylbenzaldehyde (9), 3,4-dihydroxylbenzoic acid (10), 3-methoxy-1,2-propanediol (11), β-sitosterol (12), and β-daucosterol (13). All the compounds were obtained from the plant for the first time.
