Mhodzi yemazambiringa inobvisa imhando yepolyphenols yakatorwa kubva kumbeu yemazambiringa. Inonyanya kuumbwa neprocyanidins, makatechini, epicatechins, gallic acid, epicatechin gallate uye mamwe mapolyphenols.
hunhu
Antioxidant simba
Mhodzi yemazambiringa inotorwa chinhu chakachena chepanyama. Ndiyo imwe yeanonyanya kushanda antioxidants kubva kune chirimwa masosi. Muedzo unoratidza kuti iyo antioxidant mhedzisiro ndeye 30 ~ 50 nguva yevhitamini C uye vhitamini E.
chiitiko
Procyanidins ine basa rakasimba uye inogona kuvharidzira kenza mufodya. Kugona kwavo kubata mahara radicals muchikamu chemvura ndeye 2 ~ 7 nguva dzakakwirira kupfuura iyo yeanowanzo antioxidants, senge α- Basa re tocopherol rinopfuura zvakapetwa kaviri.
extract
Yakawanikwa kuti pakati pemiti yakawanda yemiti, zvinyorwa zveproanthocyanidins mumhodzi yemazambiringa uye pine bark extract ndiyo yakanyanyisa, uye nzira huru dzekubvisa Proanthocyanidins kubva kumbeu yemazambiringa dzaive solvent extraction, microwave extraction, ultrasonic extraction uye supercritical CO2 extraction. Mbeu yemazambiringa proanthocyanidins inobvisa ine tsvina yakawanda, inoda kumwe kucheneswa kuti ivandudze kuchena kweproanthocyanidins. Nzira dzinowanzo shandiswa dzekuchenesa dzinosanganisira kubviswa kwe solvent, membrane filtration uye chromatography.
Ethanol concentration yakave nemhedzisiro yakakosha padanho rekutorwa kwembeu yemazambiringa proanthocyanidins, uye nguva yekuchera uye tembiricha yakanga isina mhedzisiro yakakosha pakutorwa kwembeu yemazambiringa proanthocyanidins. Iyo yakanyanya kudhirowa paramita yaive inotevera: ethanol concentration 70%, yekubvisa nguva 120 min, solid-liquid ratio 1:20.
Iyo static adsorption kuyedza inoratidza kuti iyo yepamusoro adsorption mwero wehpd-700 yeproanthocyanidins i82.85%, ichiteverwa neda201, inova 82.68%. Pane musiyano mudiki. Uyezve, iyo adsorption kugona kweaya maviri resin e proanthocyanidins zvakare akafanana. Muchiyedzo che desorption, da201 resin ine yakanyanya desorption rate yeprocyanidins, inova 60.58%, nepo hpd-700 ine 50.83 chete%. Yakasanganiswa neadsorption uye desorption miedzo, da210 resin yakatemwa kuve yakanakisa adsorption resin yekuparadzaniswa kweprocyanidins.
Kuburikidza nekugadzirisa maitiro, kana huwandu hweproanthocyanidins huri 0.15mg/ml, chiyero chekuyerera chiri 1ml / min, 70% ethanol mhinduro inoshandiswa seyakajeka, chiyero chekuyerera chiri 1ml / min, uye huwandu hwehuwandu huri 5bv, iyo yakatorwa. yembeu yemazambiringa proanthocyanidins inogona kucheneswa pakutanga.
