Study on the Bioactive Constituents of Piper wallichii
摘要
Abstract
Objective: To investigate the bioactive constituents in the stem of Piper wallichii. Methods; Compounds were separated by column chromatography of silica gel, ODS-A and Sephadex LH-20. Their structures were elucidated based on spectral analysis. DP-PH scavenging activity and AchE inhibitory activity were tested. Results: 10 compounds were isolated and their structures were identified as 3 ,4-methylenedioxy-benzoic acid(l) , vanillic acid(2) , benzoic acid(3) , N-p-coumaroyltyramine(4) , futoenone(5) , futo-quinol(6), isofutoquinol A(7), 4-hydroxy- 3,5-dimethoxy-benzoic acid(8) , futoamide(9), dihydropiperlonguminine(lO). Conclusion; Compounds 1 ~6 are isolated from P. Wallichii for the first time. Vanillic acid(2)and 4-hydroxy- 3,5-dimethoxy-benzoic acid (8)show scavenging activity against DPPH radical with ED50 at 224. 33μg/mL and 11.44μg/mL, respectively. No compound shows inhibition activity against AchE.关键词
