Abstract

A new sesquiterpene, incarnal, was isolated from culture fluid of Gloeostereum incarnatum (Japanese name: Nikawaurokotake). Incarnal inhibited the growth of gram-positive bacteria at 6.25-12.5 micrograms/ml. The structure of incarnal has been determined to be (1-hydroxy-2,10,10-trimethyl)-3-methylene- tricyclo[6.3.0.0(2.6)]undec-5,7-diene-4,9-dione by X-ray diffraction and spectroscopic methods.

摘要

从日本日光盘菌（日文名：日光ワロコタケ）的培养液中分离出一种新的倍半萜——肉色盘菌素。肉色盘菌素在浓度为6.25 - 12.5微克/毫升时可抑制革兰氏阳性菌的生长。通过X射线衍射和光谱学方法确定肉色盘菌素的结构为(1-羟基-2,10,10-三甲基)-3-亚甲基-三环[6.3.0.0(2.6)]十一碳-5,7-二烯-4,9-二酮。
