- New lanostanoids of Ganoderma tsugae
-
Three new compounds, (24R,S)-3α-acetoxy-24-hydroxy-5α-lanosta-8,25- dien-21-oic acid, named tsugaric acid C (1); 3α-acetoxy-5α-lanosta-8,24- diene-21-O-β-D-xyloside, named tsugarioside B (2); and 3α-acetoxy(Z)-24- methyl-5α-lanosta-8,23,25-trien-21-oic acid ester b-D-xyloside, named tsugarioside C (3), and a mixture of two known steroids were isolated from the fruit bodies of Ganoderma tsugae. The structures of 1-3 were determined by spectral and chemical methods. The cytotoxic activity of the lanostanoid constituents of this fungus was evaluated against several different cancer cell lines.
