Abstract

To research the chemical constituents from stems and leaves of Lonicera macranthoides.Various column chromatographies were employed to isolate and purify the constituents. Their structures were elucidated by spectral analysis (IR, MS, 1H-NMR, 13 C-NMR) and chemical evidence.Nine constituents were obtained and identified as loganin (I), loganic acid (II), morroniside (III),7-O-ethyl-morroniside (IV), scopoletin (V), caffeic acid (VI), chlorogenic acid (VII), beta-sitosterol (VIII), daucosterol (IX).Compounds I-VI are isolated from the plant for the first time. All the compounds are found for the first time from the stems and leaves of Lonicera macranthoides.
