Eight species of Aphyllophorales and one species of Agaricales of Basidiomycetes were examined for the triterpenoidal constituents and six compounds (I, II, III, IVa, VIIIa, IXa) were isolated and identified (Table I). The new acid from Melanoporia rosea (as the methyl ester) (IVa) was suggested to be 12β-hydroxycarbomethoxyacetylquercinic acid methyl ester.
