title: [Studies on the chemical constituents from stems and leaves of Lonicera macranthoides].
abstract: OBJECTIVE
  To research the chemical constituents from stems and leaves of Lonicera macranthoides.
  
  
  METHODS
  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.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  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.
