【 摘 要 】

Three new compounds: two flavonoids [(S)-8-formyl-3',5-dihydroxy-7-methoxy-6methylflavanone (1) and 3'-formyl-3,4',6'-trihydroxy-2'-methoxy-5'-methylchalcone (2)] and one phenylpropanoid [ethyl 3,4-methylenedioxy-5-methoxy-7,8-dihydrocinnamate (3)] were isolated from dried branches of Piper montealegreanum. Their structures were established by UV, IR, MS, 1D and 2D (1H and 13C) NMR spectroscopic techniques, besides interpretation of spectral data (1H and 13C NMR) of methylated derivatives of 1 and 2 compounds.
