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