Isolation and identification of two phenolic ketones and a chromone from Dysophylla stellata Benth.

Abstract

From the whole plant Dysophylla stellata Benth., 2′-hydroxy-4′,6′-dimethoxybutyrophenone (1), 1-(2-hydroxy-4,6-dimethoxyphenyl)but-2-en-1-one (2), and 5-hydroxy-6,7-dimethoxy-2-methylchromone (3)(stellatin) have been isolated. Their structures have been assigned on the basis of spectral evidence and synthetic experiments.
