Abstract

From the root of Pseudostellaria heterophylla a cyclopeptide, heterophyllin B, was isolated by high-speed countercurrent chromatography. Fused-silica capillary columns containing heterophyllin B as a main stationary phase component were prepared. The chromatographic selectivity of heterophyllin B showed toward aromatics, electron attracting compounds and amino acid.
