Grape noob Extract yog ib yam khoom ntuj tsim, thiab nws yog ib qho zoo tshaj plaws antioxidants los ntawm cov nroj tsuag qhov chaw pom kom deb li deb. Kev ntsuam xyuas qhia tau tias nws cov nyhuv antioxidant yog 30-50 npaug ntawm cov vitamin C thiab vitamin E. Nws yog ib qho sib xyaw ntawm polyphenols muab rho tawm los ntawm cov noob txiv hmab txiv ntoo. Qhov tseem ceeb tshaj plaws yog oligomeric proanthocyanidins, uas yog ib hom tshiab ntawm cov khoom muaj txiaj ntsig zoo antioxidant uas tsis tuaj yeem ua rau tib neeg lub cev.

Cov kev tshawb fawb tau pom tias ntawm ntau cov ntaub so ntswg, txiv hmab txiv ntoo thiab ntoo thuv bark extracts muaj cov ntsiab lus siab tshaj ntawm proanthocyanidins, thiab lub ntsiab txoj kev rau extracting proanthocyanidins los ntawm grape noob yog hnyav extraction, microwave extraction, ultrasonic extraction thiab Supercritical CO2 extraction txoj kev thiab hais txog. Grape noob proanthocyanidin extract muaj ntau impurities, thiab ntxiv purification yog xav tau los txhim kho lub purity ntawm proanthocyanidin.
Cov ethanol concentration muaj qhov cuam tshuam tseem ceeb tshaj plaws ntawm kev rho tawm ntawm cov noob txiv hmab txiv ntoo proanthocyanidins, thiab lub sij hawm rho tawm thiab qhov kub thiab txias tsis muaj qhov cuam tshuam tseem ceeb ntawm kev rho tawm ntawm cov noob txiv hmab txiv ntoo proanthocyanidins. Cov txheej txheem tshem tawm zoo tshaj plaws yog: ethanol concentration 70 feem pua, lub sijhawm rho tawm 120min, cov khoom siv-kua piv 1:20.
Qhov kev sim adsorption zoo li qub tau pom tias qhov adsorption tus nqi ntawm HPD-700 rau proanthocyanidins yog qhov siab tshaj 85 feem pua, ua raws li DA201, uas yog 82. Tib yam; Hauv kev kuaj desorption, DA201 resin muaj qhov siab tshaj plaws desorption ntawm proanthocyanidins ntawm 60 feem pua 58 feem pua, thaum lub desorption tus nqi ntawm HPD-700 ntawm proanthocyanidins tsuas yog 50 feem pua 83 feem pua. Kev sib xyaw adsorption thiab desorption thwmsim, DA210 resin tau txiav txim siab los ua qhov zoo tshaj plaws adsorption resin rau cais cov proanthocyanidins.

Cov nyhuv ntawm grape noob extract hauv txo cov ntshav lipids. Cov noob txiv hmab txiv ntoo yog nplua nuj nyob rau hauv ntau tshaj 100 yam tshuaj zoo. Ntawm lawv, unsaturated fatty acid linoleic acid (uas yog ib qho tseem ceeb tab sis tsis yog synthesized los ntawm tib neeg lub cev) account rau 68-76 feem pua thiab nyob rau hauv qeb thawj ntawm cov roj qoob loo. Kev noj 20 feem pua ntawm cov cholesterol tuaj yeem txo cov ntshav lipids.
