title: [Chemical constituents and bioactivity of Kalimeris indica].
abstract: OBJECTIVE
  To study the constituents of Kalimeris indica and its bioactivity.
  
  
  METHODS
  The constituents were isolated by various chromatographic techniques and their structures were elucidated by their physicochemical properties and the spectral data analysis. Use the disk diffusion method, see whether a sample can produce inhibition zone and its round size, semi-quantitatively evaluate the samples antimicrobial activity.
  
  
  RESULTS
  Eight compounds were isolated and identified as succinic acid (1), glycerolmonopalmitate (2), protocatechuic acid (3), uracil (4), syringic acid (5), protocatechuic acid methyl ester (6), esculetin (7), medicagenic acid (8). The result of activity screening indicate that succinic and syringic acid have bacteriostasis to bacillus subtilis.
  
  
  CONCLUSIONS
  All Compounds were isolated from the genus Kalimeris for the first time, succinic acid (1) and syringic acid (5) have bacteriostasis to bacillus subtilis.
