Abstract:
Objective To study the chemical constituents of Peperomia dindygulensis. Methods Chromatography was used to isolate and purify the chemical constituents, their structures were identified by spectral analyses. Results Eight compounds were isolated and identified as bis-(2-methoxy-4, 5-methylenedioxy)-benzophenone (Ⅰ), peperomin B (Ⅱ), peperomin C (Ⅲ), 5-hydroxy-4′, 7, 8-trimethoxy flavone (Ⅳ), 5-hydroxy-3′, 4′, 7, 8-tetramethoxy flavone (Ⅴ), 5, 3′-dihydroxy-4′, 7, 8-trimethoxy flavone (Ⅵ), ?-sitosterol (Ⅶ), hexadecanoic acid (Ⅷ). Conclusion Compound Ⅰ is a new compound named as dindygulensin. All compounds, except Ⅴ, are isolated from P. dindygulensis for the first time.
