Cathayanalactone G and other constituents from leaves and twigs of Callicarpa cathayana
文献摘要：
Objective:To study the chemical constituents from the leaves and twigs of Callicarpa cathayana.Methods:The chemical constituents were isolated and purified by column chromatography on silica gel,MCI gel CHP 20P/P120,Sephadex LH-20,and HPLC.The structures of the compounds were determined by HR-ESI-MS,1D and 2D NMR data.Results:A total of 24 compounds were isolated from the 85％methanol extract of leaves and twigs of C.cathayana.They were identified as cathayanalactone G(1),a new diterpene,and 23 known compounds as patagonic acid(2),(-)-16-hydroxycledroda-3,13-dien-16,15-olide-18-oic acid(3),15-methoxypatagonic acid(4),oleanolic acid(5),ursolic acid(6),siaresinolic acid(7),pomolic acid(8),α-amyrin(9),tormentic acid(10),lupeol(11),5,7-dihydroxy-3,4'-dimethoxyflavone(12),5,4'-dihydroxy-3,7,3'-dimethoxyfla-vone(13),5-hydroxy-3,6,7,4'-tetramethoxyflavone(14),salvigenin(15),kaemferol(16),astragalin(17),pinoresinol 4-O-β-D-glucopyranoside(18),paulownin(19),β-sitosterol(20),β-sitosterol β-D-glucopyranoside(21),5-hydroxy-coumarin(22),isocopoletin(23),and 4-hydroxycinnamic acid(24).Conclusion:Compound 1 is a new labdane diterpene.Compounds 10,13,16 and 17 are isolated from the genus Callicarpa for the first time.Compounds 7,8,9,12,14,23 and 24 are reported from C.cathayana for the first time.
