Chemical Compositions of Effective Part in Total Polyphenols From Pomegranate Peel
Objective:To study the chemical constituents from n-butyl alcohol extracts of total polyphenols effective part from pomegranate peel,expound the material foundation of its anti-tumor effect,and provide scientific basis for its development and utilization.Method:Separation techniques such as silica gel column chromatography,reversed-phase silica gel column chromatography and preparation liquid chromatography were used,and 6 monomer compounds were isolated from total polyphenols effective part from pomegranate peel.Their structures were identified according to the physicochemical properties,1H-NMR spectroscopy data and 13C-NMR spectroscopy data.Result:Six monomer compounds were obtained from n-butyl alcohol extracts of total polyphenols effective part from pomegranate peel,and were identified as narcissin (1),1-O-glaloyl-β-D-glucos (2),tachioside (3),p-hydroxybenzoic acid glucose ester (4),coumaric acid glucose ester (5),2-phenylethyl rutinoside (6).Conclusion:All other compounds except compound 2 were isolated from pomegranate peel for the first time.
