New terpene-linked cyclohexenone epoxides, macrophorin A, B and C, produced by the fungus caused Macrophoma fruit rot of apple.

Abstract

In the course of our search for fruit rot phytotoxins produced by the fungus caused Macrophoma^fruit rot of apple, we isolated a new terpene-linked cyclohexenone epoxide, which is designated as macrophorin A, from the culture filtrate. Its antimicrobial and cytotoxic activities were considerably high,
