Does [ Studies on the chemical constituents from stem and leaves of Lonicera macranthoides ]? Context: 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).
