Abstract: In order to screen out the best variety from 17 kind of different Zanthoxylun bungeanum pericarp, the contents of total polyphenols, total flavonoids, hemp flavor substance and the antioxidant ability of the extracts of 17 different varieties of high yield Zanthoxylum bungeanum pericarp were studied in this paper, and the correlation analysis was also conducted. The results showed that the content of total polyphenols, total flavonoids and hemp flavor substances were the highest in the sample of M37, M1 originated from Mianchi and S1 obtained from Shanxian, respectively.And the sample of M31 had the lowest content of total polyphenols and total flavonoids. The lowest content of hemp flavoring was sample of M4. The extracts of different Zanthoxylum bungeanum pericarp presented favorable reducing power and DPPH scavenging ability.And the total polyphenols and total flavonoids showed highly correlation with the reducing power and DPPH scavening capacity.The study showed that the main active ingredients of different Zanthoxylun bugeanum pericaip present significant difference, and the M37, M1, L1 and S1 originated from Mianchi, Mianchi, Lingbao, Shanxian, respectively, could be used to further cultivate.
