title: [Chemical Constituents of Citrus medica Fruit].
abstract: OBJECTIVE
  To study the chemical constituents of Citrus medica fruit.
  
  
  METHODS
  The fruit of Citrus medica was extracted with 95% EtOH, and the compounds were separated and purified by silica gel, RP-18 and Sephadex LH-20 column chromatography. The structures were identified by spectroscopic analysis.
  
  
  RESULTS
  A total of 16 compounds were isolated and identified, including methyl ferulic acid (1), dihydro-N-caffeoyltyramine (2) acacetin (3), β-ecdysterone (4), (-)-balanophonin (5), p-methoxy cinnamic acid (6), umbelliferone (7), ferulic acid (8), pyrocatechualdehyde (9), diosmetin (10), 4-methoxy salicylic acid (1), β-amyrin acetate (12), epigallocatechin (13), betulinic acid (14), lupeol (15) and nicotinamide (16).
  
  
  CONCLUSIONS
  All the compounds are isolated from the fruit of Citrus medica for the first time.
