From the ether-extracted residue of alcohol extract of fruit-body of Fomes pinicola, two substances, A[mp. 260〜263℃(decomp.), [α]^<15>_D=8.6°(in pyridine)] and B [mp. 305〜308℃(decomp.), [α]^<23>_D=+43°(in pyridine)] having their formula as C_<30>H_<46>O_4 were isolated. They have one double bond and one carboxyl group, and were likely to belong to triterpenoid on color-reactions. In A one carbonyl group is ascertained as 2,4-dinitrophenylhydrazone, but from B carbonyl derivative is not obtained. A gives a methyl ester mp. 181〜181.5℃, [α]^9_D=+20.8°(in chloroform) and a monoacetate mp. 177〜180℃, and B gives a methyleester mp. 178〜178.5℃[α]^9_D=+44°(in chloroform) and, as an acetate, a needle crystal mp. 160〜162℃, thouth its formula is corresponding to C_<32>H_<46>O_8.
