摘要
Two novel flavonoids, myrsininone A （1）, an isoflavone and myrsininone B （2）, a flavanone, with very strong antibacterial activities, were isolated from the stems of Myrsine africana L. Their structures were elucidated by extensive spectroscopic analyses. The antibacterial activities were determined by modified Resazuric MIC methods.
