鹰爪叶化学成分研究

STUDIES ON THE CHEMICAL CONSTITUENTS OF THE LEAVES FROM ARTABOTRYS HEXAPETALUS

从鹰爪Ａｒｔａｂｏｔｒｙｓｈｅｘａｐｅｔａｌｕｓ叶分得５种黄酮：鹰爪甙Ａ（１），鹰爪甙Ｂ（２），黄杉素（３），木犀草素７Ｏ葡萄糖甙（４），芹菜素７Ｏ芹糖（１→２）葡萄糖甙（５），以及琥珀酸（６）和富马酸（７）。其中１和２是新的黄酮甙，其他５种成分为第一次从本植物分得。

Artabotrys hexapetalus (annonaceae) is distributed in southern China. As a Chinese folk herb medicine, its root and fruits are used to treat malaria and scrofula, respectively. Two new flavonol glycosides, artabotrysideA (1), B (2), three known flavonoids: taxifolin (3), 7Oglucoluteolin (4), apigenin7Oapiosyl(1→2) glycoside (5), and two organic acid: succinic (6) and fumaric acid (7) have been isolated from the leaves of A.hexapetalus. The structures of 1 and 2 were elucidated as quercetin3OαLrhamnopyranosyl(1→2)αLarabinofuranoside (1) and kaempferol3OαLrhamnopyranosyl(1→2)αLarabinofuranoside (2), respectively, on the basis of spectral analysis. The compounds 3 through 7 were found from A.hexapetalus for the first time.
