Objective:
To study the chemical constituents of Lonicera macranthoides.
Methods:
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.
Results:
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).
Conclusion:
The compounds 6,7 and 13 are obtained from this plant for the first time.
