Structures and cytotoxicities of three new sesquiterpenes from cultures of Armillaria sp.

Abstract

Abstract

Three new sesquiterpene aryl esters, named 10-dehydroxy-melleoliede B ( 1), 1- O-formyl-10-dehydroxy-melleoliede B ( 2) and 10-oxo-melleoliede B ( 3) together with six known ones ( 4– 9), were isolated from the cultures of Armillaria sp. The structures of the new compounds were elucidated based on the extensive spectroscopic methods. Compounds 1, 2, and 5– 9 exhibited moderate cytotoxicities.
