Abstract

Antidesma ghaesembilla is an important medicinal and food plant in many Asian countries. Ten substances could be isolated from the dichloromethane and methanol extract: sitostenone (3), daucosterol (4), chavibetol (5), asperphenamate (6), protocatechuic acid (7), vanillic acid-4-O-β-D-glucoside (8), 1-O-β-D-glucopyranosyl-3-O-methyl-phloroglucinol (9), and aristolic acid II-8-O-β-D-glucoside (10), and two new aristolic acid derivatives, 10-amino-5,7-dimethoxy-aristolic acid II (= 6-amino-9,11-dimethoxyphenanthro[3,4-d]-1,3-dioxole-5-carboxylic acid; 1) and 5,7-dimethoxy-aristolochic acid II (= 9,11-dimethoxy-6-nitrophenantro[3,4-d]-1,3-dioxole-5-carboxylic acid; 2). Exposure to humans of some of these compounds is associated with a severe disease today known as aristolochic acid nephropathy. Therefore, the traditional usage of this plant has to be reconsidered carefully.

* Dedicated to Professor Dr. Max Wichtl in recognition of his outstanding contribution to phytotherapy research.
