[Chemical constituents from stems of Lonicera macranthoides].
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).


CONCLUSIONS
The compounds 6,7 and 13 are obtained from this plant for the first time.
