【 摘 要 】

Three flavanones, two chalcones and one dihydrochalcone were isolated from the branches of Piper glandulosissimum. All isolated compounds were characterized based on IR, UV, 1H and 13C NMR, including 2D NMR analyses (HMQC, HMBC, COSY and NOESY) and comparison with the literature. The compound 7-hydroxy-5,8-dimethoxyflavanone displayed antimicrobial activity against Staphylococcus aureus, S. epidermidis, Trichophyton mentagrophytes and Microsporum canis.
