- Abstract
[Objective]To isolate and purify the xanthones from Lomatogonium, carinthiacum. [Methods] High-speed counter-current chromatography method (HSCCC), combined with macroporous resin chromatography were applied to the separation and purification of xanthones from L. carinthiacum; and the chemical structural identification was carried out by spectroscopic methods, including HR-ESI-MS and extensive ID and 2D NMR techniques. [Results] Seven xanthones were obtained., namely 1,4,8-trimethoxyxanthone-6-0-β-D-glucoronyl-(1-6) -0-β-D-glucoside (1), 1,2,6-trihydroxyxanthone-8-0-β-D-glucoside (2), 1,5,8-trihydroxy-3-methoxyxanthone (3), 1,8-dihydroxy-3,4,5-trime-thoxyxanthone (4), 8-hydroxy-l,3,5-trimethoxyxanthone (5), l-hydroxy-3,5,8-trimethoxyxanthone (6) and 1,8-dihydroxy-4,5-dimethoxy-6, 7-methylenedioxyxanthone (7) [Conclusions] Compounds 1, 2 and 7 were separated from L. carinthiacum for the first time.
