[Chemical constituents from stems of Lonicera macranthoides].Zhong Yao Cai. 2012 Jan; 35(1):66-9.ZY
To study the chemical constituents of Lonicera macranthoides.
Many chromatography means were used in separation and purification, and the structures of all compounds were identified by the means of spectroscopic analysis (MS, 1H-NMR, 13C-NMR) and physicochemical properties.
13 compounds were elucidated as beta-sitosterol (1), daucosterol (2), chlorogenic acid (3), luteolin (4), quercetin (5), diosmetin-7-O-beta-D-glucoside (6), kaempferol-3-O-beta-D-glucoside (7), 3,4-O-di-caffeoylquinic acid methylester (8), 1,3-O-di-caffeoylquinic acid (9), scopoletin (10), macranthoidin B (11), macranthoidin A (12), eriodictyol (13).
The compounds 6,7 and 13 are obtained from this plant for the first time.
