Abstract: Various organic and aqueous extracts of aerial part of Boenninghausenia albiflora (Rutaceae) obtained by infusion and maceration were screened for their antimicrobial activity against eight animal and plant pathogenic bacteria (Bacillus subtilis, Staphylococcus aureus, Erwinia chrysanthemi, Escherichia coli, Proteus vulgaris, Xanthomonas phaseoli, Agrobacterium tumefaciens and Xanthomonas campestris) using disc diffusion method. Out of total 32 tests performed, 27 tests showed positive antibacterial activity at 1000 mg/ml concentration, whereas 15 instances exhibited zone of inhibition ³ 10 mm at same concentration. The activity shown by some of the extracts was found higher than ampicillin (10 mcg) and erythromycin (15 mcg), standard antibiotic used.

Abstract: From the methanolic extract of the leaves of Boenninghausenia albiflora MEISSNER var. japonica S. SUZUKI, a new coumarin, named matsukaze-lactone (I), C20H14O6, m.p. 267∼268°, was isolated. Methylation of I with dimethyl sulfate and methanolic alkali gave an acid (IIa), C22H22O8, which was oxidized to an acid (IIIa), C18H18O8. 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.
