Three New Lanostanoids from Ganoderma lucidum

Abstract
Three new lanostanoids.sbd.ganodermenonol (1), ganodermadiol (2), and ganodermatriol (3) [isolated as its triacetate derivative (3a)].sbd.were isolated from the MeOH extract of Ganoderma lucidum, together with ergosterol and its peroxide. The new compounds were identified as 26-hydroxy-5.alpha.-lanosta-7,9(11),24-trien-3-one (1), 5.alpha.-lanosta-7,9(11),24-triene-3.beta.,26-diol(2), and 5.alpha.-lanosta-7,9(11),24-triene-3.beta.,26,27-triol (3) by their respective spectral data.
