Preparative isolation of closely-related xanthones from Gentianella amarella ssp. acuta by High-speed countercurrent chromatography.

Abstract

INTRODUCTION A methanolic extract from Gentianella amarella ssp. acuta was shown to contain several xanthones exhibiting acetylcholinesterase inhibitory activity. These xanthones were difficult to separate by conventional LC techniques, which prevented the isolation of pure compounds in sufficient amounts to perform in-depth biological testing.
