In our effort to find antioxidants from the higher fungi, we isolated three new compounds (1-3) with a known compound, spirobenzofuran (4), from the culture broth of Hericium coralloides. Bioassay-guided fractionation led to the isolation of these compounds, and we determined the chemical structures through spectroscopic methods. These compounds exhibited antioxidant activity in the range of IC₅₀ values of 29-66 μM in the 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical-scavenging assay.

来自猴头菌的培养液中的新抗氧化剂。

为了从高等真菌中寻找抗氧化剂，我们从猴头菌的培养液中分离了三种新化合物（1-3）和一种已知化合物，螺苯并呋喃（4）。生物测定指导的分级分离导致这些化合物的分离，我们通过光谱方法确定了化学结构。这些化合物在2,2'-叠氮基双-（3-乙基苯并噻唑啉-6-磺酸）（ABTS）自由基清除试验中的IC ₅₀值范围为29-66μM，表现出抗氧化活性。
