摘要
目的:研究番石榴叶的化学成分。方法:利用硅胶、Sephadex LH-20、MPLC等色谱方法进行分离纯化,根据理化性质、波谱数据进行结构鉴定。结果:从番石榴叶的正丁醇部位中分离得到7个化合物,分别鉴定为:桑黄素阿拉伯糖苷(1)、桑黄素来苏糖苷(2)、2,6-dihydroxy-4-O-β-D-glucopyranosyl-benzophenone(3)、木麻黄鞣亭(4)、2,6-dihydroxy-3,5-dimethyl-4-O-(6″-O-galloyl-β-D-glucopyranosyl)-benzophenone(5)、globulusin A(6)、山柰酚-3-O-(6″-没食子酰基)-β-D-半乳糖苷(7)。结论:其中,化合物3、5-7为首次从该植物中分离得到。
Objective: To study the chemical constituents of the leaves of Psidium guajava. Methods: The chemical constituents were isolated by column chromatography on silica gel,Sephadex LH-20 and MPLC. Their chemical structures were elucidated on the basis of special analysis. Results: Seven compounds were isolated from n-butyl alcohol fraction,whose structures were elucidated as morin-3-O-α-L-arabopyranoside( 1),morin-3-O-α-L-iyxopyranoside( 2),2,6-dihydroxy-4-O-β-D-glucopyranosyl-benzophenone( 3),casuarictin( 4),2,6-dihydroxy-3,5-dimethyl-4-O-( 6″-O-galloyl-β-D-glucopyranosyl)-benzophenone( 5),globulusin A( 6),and kaempferol-3-O-β-D-( 6″-galloyl) galactopyranoside( 7). Conclusion: Compounds 3 and 5 - 7 are isolated from this plant for the first time.
