Abstract
The polyphenols were extracted with three methods from six pomegranate peels and the total polyphenol,total flavonoid and tannin of the extracts were detemined,in order to developing functional food and nutraceutical and optimizing analytical methods.The results showed that: The extraction method did not effected significantly on the extractive yield of total polyphenol and total flavonoid,but of tannin,to which the yields increased gradually with 70 % acetone,70 % ethanol and 20 % ethanol as extactive solvent respectively.The compounds’contents of different peels were different high significantly.The mutual effect between extraction method and variety of peel was no significant impact on the extractive yield.There were significant(P0.01) linear-correlations among the contents of the three compounds in anyone of the six peels,no matter which extractive method being used.
