title: [Chemical constituents of Trichosanthes kirilowii peels].
abstract: OBJECTIVE
  To study the chemical constituents of the peels of Trichosanthes kirilowii.
  
  
  METHODS
  Many chromatographic techniques were used including repeated silica column chromatography, polyamide resin and semi-preparative high performance liquid chromatography. According to the physical and chemical properties and spectral analysis, the chemical structures of the compounds were determined.
  
  
  RESULTS
  Thirteen compounds were isolated and identified as quercetin-3-O-[alpha-L-rhamnose(1 --> 2)-beta-D-glucopyranosyl]-5-O-beta-D-glucopyranoside (1), quercetin-3-O-rutinoside (2), apigenin-7-O-beta-D-glucopyranoside (3), diosmetin-7-O-beta-D-glucopyranoside (4), luteolin (5), apigenin (6), diosmetin (7), methyl palmitate (8), methyl stearate (9), palmitic acid (10), beta-sitosterol (11), alpha-spin-asterol (12) and stigmasterol (13).
  
  
  CONCLUSIONS
  Compounds 1 - 3, 5 - 7 are isolated from this plant for the first time.
