摘要：

In addition to stigmasterol, piperiton, methyl 2,2-dimethyl-2H-chromene-6-carboxylate, methyl 3-(2-hydroxy-3-methyl-3-butenyl)-4-hydroxy-benzoate and methyl (6S)-2-trans-6-hydroxy-2,6-dimethyl-2,7-octadienoate, three new natural products were isolated from Piper aduncum and characterized as methyl 8-hydroxy-2,2-dimethyl-2H-chromene-6-carboxylate, 2,2-dimethyl-8(3-methyl-2-butenyl)-2H-chromene-6-carboxylic acid and methyl 3-(6-hydroxy-3,7-dimethyl-2,7-octadienyl)-4-methoxy-benzoate. The structures of all isolates were elucidated by spectroscopic methods, mainly 1D and 2D NMR spectroscopy. The antibacterial, antifungal and molluscicidal activities of the isolates were also investigated.
