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 13 C-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.
