Kugwiritsa ntchito ma polyphenols nthawi zambiri kumalumikizidwa ndi kuchepa kwa matenda osokonekera.Ambiri mwa ma antioxidants achilengedwewa amachokera ku zipatso, ndiwo zamasamba, zonunkhira, mbewu ndi zitsamba.Pachifukwa ichi, pakhala kuwonjezeka chidwi kudziwa zomera Tingafinye mankhwala.Ma polymeric tannins ndi monomeric flavonoids, monga catechin ndi epicatechin, mu khungwa la paini ndi zotulutsa tiyi wobiriwira zitha kukhala ndi udindo wopanga ma antioxidant azinthu izi.Cholinga cha phunziroli chinali kuwonetsa mankhwala a phenolic mu khungwa la pine ndi tiyi wobiriwira wokhazikika pogwiritsa ntchito chromatography yamadzimadzi yogwira ntchito kwambiri komanso electrospray ionization mass spectrometry (HPLC-ESI-QTOF-MS).Okwana 37 ndi 35 mankhwala kuchokera paini khungwa ndi wobiriwira tiyi akupanga, motero, ankadziwika kuti a m'makalasi osiyanasiyana structural, makamaka flavan-3-ol ndi zotumphukira zake (kuphatikiza procyanidins).Mphamvu ya antioxidant yazinthu zonse ziwirizi idawunikidwa ndi njira zitatu zovomerezeka za antioxidant: Trolox equivalent antioxidant capacity (TEAC), ferric reduction antioxidant power (FRAP) ndi oxygen radical absorbance capacity (ORAC).Zochita zapamwamba za antioxidant mwa njira iliyonse zidapezedwa.Kuphatikiza apo, polyphenol yonse ndi flavan-3-ol zomwe zili mkati, zomwe zidatsimikiziridwa ndi Folin-Ciocalteu ndi vanillin assays, motero, zidawonetsa kuchuluka kwa gallic acid ndi (+) -catechin ofanana.
