ABSTRACT
Objective To investigate the chemical constituents in the vines of Piper hancei for obtaining a more comprehensive understanding on its effective components. Methods Compounds were separated by column chromatography with silica gel and polyamide, and their structures were elucidated by spectral analysis and chemical evidence (IR, UV, MS, (~1H-NMR), (~(13)C-NMR)). Results Nine compounds were isolated from the chloroform extract fraction. Their structures were identified as futoamide (Ⅰ), trichostachine (Ⅱ), retrofractamide A (Ⅲ), pipercide (Ⅳ), guineensine (Ⅴ), piperine (Ⅵ), piperettine (Ⅶ), piperovatine (Ⅷ), and (2E, 4E)-N-isobutyl-7-(3, 4-methylenedioxyphenyl)-hepta-2, 4-dienamide (Ⅸ). (Conclusion )Compounds Ⅱ-Ⅳ and Ⅶ-Ⅸ are isolated from the plant for the first time.
