Isticmaalka polyphenols ayaa inta badan lala xiriiriyay dhacdooyinka hoose ee cudurrada xumaaday.Inta badan antioxidants-ka dabiiciga ah waxay ka yimaadaan miraha, khudaarta, xawaashka, badarka iyo geedo yaryar.Sababtan awgeed, waxaa jiray xiisaha sii kordhaya ee lagu ogaanayo xeryahooda laga soo saaro dhirta.Polymeric tannins iyo monomeric flavonoids, sida catechin iyo epicatechin, oo ku jira jilif geed iyo shaaha cagaaran ayaa mas'uul ka noqon kara hawlaha sare ee antioxidant-ka ee waxyaabahan.Ujeedada daraasadda hadda jirta waxay ahayd in lagu sifeeyo xeryahooda phenolic ee jilif geedka iyo shaaha cagaaran ee xoogga leh iyadoo la adeegsanayo chromatography dareeraha waxqabadka sare leh oo ay weheliso spectrometry mass spectrometry (HPLC-ESI-QTOF-MS).Isku-darka 37 iyo 35 oo ka kooban jilif geed iyo shaaha cagaaran, siday u kala horreeyaan, ayaa loo aqoonsaday inay ka tirsan yihiin fasallo dhismeed oo kala duwan, oo u badan flavan-3-ol iyo waxyaabaha ka soo baxa (ay ku jiraan procyanidins).Awoodda antioxidant-ka ee labada qayboodba waxaa lagu qiimeeyay saddex hab oo firfircoonida antioxidant-ka ah: Awoodda antioxidant u dhigma ee Trolox (TEAC), ferric yaraynta awoodda antioxidant (FRAP) iyo awoodda nuugista xag-jirta oksijiinta (ORAC).Qiimaha firfircoonida antioxidant sare ee hab kasta ayaa la helay.Intaa waxaa dheer, wadarta guud ee polyphenol iyo flavan-3-ol, kuwaas oo lagu go'aamiyay Folin-Ciocalteu iyo vanillin assays, siday u kala horreeyaan, waxay muujiyeen xaddi sare oo ah galic acid iyo (+) -catechin oo u dhigma.
