title: [New beta-carboline alkaloids contained in Psammosilene tunicoides].
abstract: OBJECTIVE
  To study the chemical constituents of Psammosilene tunicoides.
  
  
  METHODS
  The two chemical constituents were separated by various chromatographic methods, and their structures were identified on the basis of spectroscopic analysis.
  
  
  RESULTS
  Two beta-carboline alkaloids were separated from normal butanol fraction of P. tunicoides, and identified as 1-acetyl-3-methoxycarbonyl-beta-carboline (1) and 1-acetyl-3-methoxycarbonyl-4-hydroxyl-beta-carboline (2).
  
  
  CONCLUSIONS
  Compound 1 is separated from this plant as natural products for the first time, and compound 2 was a new compound.
