　　Ganoderma comphoratum Zang et Su, SP. nov., growing rarely on the inner cavity wall of Cinnamomum comphora (L) Prcsl. in Taiwan, is a new genus of Ganoderma species. The methanolic extract of the fruiting body of the ganoderma comphoratum is separated by column chromatography, normal phase high performance liquid chromatography. As a result, thirteen compounds were isolated and identified by the spectral analysis. These Compounds are:
　　＊Compound A：4α-Methylergost-8, 24 (28)-dien-3, 11-dion-26-oic acid.
　　　Compound B：4α-Methylergost-8, 24 (28)-dien-3, 7, 11-trion -26-oic acid.
　　＊Compound C：7β-Hydroxy-4a-methylergost-8, 24(28)-dien-3, 11-dion-26-oic acid.
　　　Compound D：7β-Hydroxy-4a-methylergost-8, 24(28)-dien-3, 7, 11-trion-26-oic acid.
　　＊Compound E：4α-Methylergost-8, 14, 24 (28)-trien-3, 11-dion-26-oic acid.
　　＊Compound F：7β-Hydroxy-4α-methylergost-8, 14, 24(28)-trien-3, 11-dion-26-oic acid.
　　＊Compound G：Methyl-3α, 2α-dihydroxy-4α-methylergost-8, 24(28)-dien-7, 11-dion-26-oate.
　　＊Compound H：2, 2'', 5, 5'' -tetramethoxy-3, 4, 3'', 4''-di-methylenedioxy-6, 6''-dimethyl biphenyl.
　　　Compound I：3β-Hydroxy-24-methylenelanost-7, 9(11)-dien-21-oic acid.
　　　Compound J：3β, 15α-Dihydroxy-24-methylenelanost-7, 9(11)-dien-21-oic acid.
　　　Compound K：24-Methylenedihydrolanosterol.
　　　Compound L：9(E)-Octadecenoic acid.
　　　Compound M：9, 12(E, E)-Octadecadienoic acid.
　　There were six new compounds (＊ symbol) which haven''t reported on any paper.
