  Abstract The new isocoumarin, 9,10-dihydroxy-5, 7-dimethoxy-1H-naphtho(2,3 c )pyran-1-one, was isolated from the capitula of Paepalanthus bromelioides . The structure was established by means of the spectral data of the natural product and its derivatives. The natural isocoumarin isolated has strong antibiotic activity.

  摘要 从Paepalanthus bromelioides的头状花序中分离得到新的异香豆素9,10-二羟基-5, 7-二甲氧基-1H-naphtho(2,3c)pyran-1-one。该结构是通过天然产物及其衍生物的光谱数据建立的。分离出的天然异香豆素具有很强的抗菌活性。
