From the methanolic extract of the leaves of Boenninghausenia albiflora MEISSNER var. japonica S. SUZUKI, a new coumarin, named matsukaze-lactone (I), C_<20>H_<14>O_6,m.p. 267〜268°, was isolated. Methylation of I with dimethyl sulfate and methanolic alkali gave an acid (IIa), C_<22>H_<22>O_8,which was oxidized to an acid (IIIa), C_<18>H_<18>O_8. By decarboxylation of IIIa with copper powder, 2,2', 4,6'-tetramethoxybiphenyl (V) was obtained. From these results, the structural formula (Ia), (Ib) and (Ic) were proposed for matsukaze-Iactone.
