摘要
Two new lanostanoids together with two known lanostanoids, 3 beta-hydroxy-5 alpha-lanosta-8,24-dien-21-oic acid and 3-oxo-5 alpha-lanosta-8,24-dien-21-oic acid, and a known steroid,ergosta-7,22-dien-3 beta-ol have been isolated from formosan Ganoderma tsugae. The new lanostanoids were characterized as 3 alpha-acetoxy-5 alpha-lanosta-8,24-dien-21-oic acid, named tsugaric acid A, and 3 alpha-acetoxy-16 alpha-hydroxy-24 xi-methyl-5 alpha-lanosta-8,25-dien-21-oic acid, named tsugaric acid B.
