Kuv, Qhov chaw thiab keeb kwm ntawm pterostilbene
Pterostilbene yog ib yam tshuaj muaj nyob rau hauv rosewood, tab sis cov kws tshawb fawb kuj tau pom muaj pterostilbene nyob rau hauv lwm yam nroj tsuag. Txawm li cas los xij, vim tias nws tau pom thawj zaug nrog hom rosewood, nws tau hu ua pterostilbene. Pterostilbene yog ib qho dawb los yog dawb dawb hmoov siv lead ua nrog nplua nuj nqi tshuaj. Nws yog ib qho tshuaj tiv thaiv kab mob hauv cov khoom siv ntshav qhuav thiab muaj qee yam cuam tshuam rau kev kho mob ntshav siab thiab hyperlipidemia. Pterostilbene yog cov khoom siv tshuaj tua kab mob hauv cov khoom siv ntshav. Nws yog polyhydroxy stilbene compound thiab homologue ntawm resveratrol. Ntxiv rau qhov ua ib feem zoo ib yam li resveratrol hauv nws cov tshuaj pharmacological, nws kuj muaj zog Antifungal kev ua haujlwm (nws cov tshuaj tiv thaiv kab mob yog tsib npaug ntawm resveratrol).
II, Cov khoom noj khoom haus ntawm Pterostilbene
Pterostilbene yog nplua nuj nyob rau hauv ntau yam as-ham, nrog rau cov vitamins, amino acids thiab polysaccharides. Cov khoom xyaw no muab cov khoom noj muaj txiaj ntsig zoo rau tib neeg lub cev, thiab muaj lub luag haujlwm ntawm kev tswj lub cev ua haujlwm thiab txhim kho kev tiv thaiv.
III, Kev ua tau zoo ntawm pterostilbene
1. Anti-aging Pterostilbene yog nplua nuj nyob rau hauv antioxidant tshuaj, xws li flavonoids thiab vitamin C, uas yuav neutralize dawb radicals nyob rau hauv lub cev, inhibit cell aging, thiab ncua kev laus.
2. Txhim kho kev tiv thaiv kab mob Pterostilbene muaj kev tiv thaiv kab mob, uas tuaj yeem txhim kho lub cev tiv thaiv kab mob thiab txhim kho kab mob. Nws tuaj yeem nce tus lej thiab kev ua haujlwm ntawm cov qe ntshav dawb, txhawb kev loj hlob ntawm lymphocytes, thiab txhim kho qib ntawm cov tshuaj tiv thaiv hauv lub cev, yog li txhim kho kev tiv thaiv kab mob.
3. Txo cov ntshav qab zib, tiv thaiv ntshav qab zib
Cov polysaccharide hauv pterostilbene muaj cov txiaj ntsig ntawm kev txo cov ntshav qab zib, tuaj yeem tswj hwm kev tso tawm ntawm insulin, txhim kho qhov rhiab heev ntawm insulin, yog li txo cov ntshav qab zib, thiab muaj cov txiaj ntsig ntawm kev kho mob ntshav qab zib.
4. Txhawb cov ntshav ncig Pterostilbene tuaj yeem txhawb cov ntshav ncig, txhim kho microcirculation tsis zoo, nce elasticity thiab permeability ntawm capillaries, yog li txhim kho cov ntshav thiab oxygen, thiab txhim kho cov kab mob plawv thiab cerebrovascular.
5. Txo qhov mob Pterostilbene muaj kev tiv thaiv kab mob, tuaj yeem tiv thaiv kev mob, txo cov tsos mob, thiab txo qhov mob thiab tsis xis nyob los ntawm kev mob.
IV, Pterostilbene yog dab tsi
Pterostilbene, uas muaj nyob hauv ntau cov txiv hmab txiv ntoo, muaj ntau yam txiaj ntsig kev noj qab haus huv, suav nrog tshuaj tiv thaiv hypertriglyceridemic, anti-hypercholesterolemic. Blueberries, cranberries thiab liab txiv hmab txiv ntoo feem ntau muaj qee qhov pterostilbene. Kev noj cov txiv hmab txiv ntoo no thiab lwm yam khoom noj uas muaj cov tshuaj no tuaj yeem pab txo qis kev pheej hmoo ntawm kab mob plawv thiab kuj tseem tuaj yeem pab ntxiv dag zog rau kev nco.Tom qab xyoo ntawm kev sim ntawm cov tsiaj, Asmeskas cov kws tshawb fawb pom tau tias cov tshuaj tau muab rho tawm los ntawm blueberries thiab txiv hmab txiv ntoo tuaj yeem inhibit ib qho enzyme hu ua. P450 cytochrome, uas tuaj yeem qhib cov tshuaj carcinogens, thiab tuaj yeem txo qis lipoprotein cholesterol. Rosewood stilbene yog ib tug muaj ntxhiab hydrocarbon hu ua "styrene", uas yog ib tug derivative ntawm resveratrol. Thaum ntxov xyoo 1990, Asmeskas cov kws tshawb fawb pom tias resveratrol muaj cov haujlwm ntawm kev tiv thaiv kab mob plawv, thiab nws pom muaj ntau hauv cov tawv nqaij liab liab.
V, Pterostilbene&Resveratrol
Pterostilbene - muaj qee yam zoo sib xws ntawm resveratrol, yog ib qho zoo dua dimethylated derivative, muaj qhov nqus tau zoo tshaj plaws, Pterostilbene muaj cov methylated stilbene molecule zoo ib yam li resveratrol qauv, qhov txawv tsuas yog Pterostilbene molecules hloov resveratrol molecules, vim hais tias ntawm pawg hydroxyl. Pterostilbene muaj ob methoxy-methylation, Nws kuj tseem zoo dua hauv qhov ncauj nqus thiab tej zaum yuav muaj zog antioxidant. Resveratrol txhawb nqa cell apoptosis thiab yog ib qho tseem ceeb hauv kev cuam tshuam rau lub hom phiaj tsiv teb tsaws ntawm qia hlwb los ntawm cov ntshav mus rau cov ntaub so ntswg. Txawm li cas los xij, Rosewood tuaj yeem txo qis- tswj kev qhia ntawm iNOS thiab COX-2 noob, uas tuaj yeem pab txhawb kev noj qab haus huv ntawm cov ntaub so ntswg.
Cov nyhuv ntawm resveratrol ntawm qis concentration yog ntau dua li cov nyhuv anti-inflammatory ntawm resveratrol. Rosewood kuj yog phytoantitoxin (phytochemical tiv thaiv) zoo ib yam li resveratrol, teej tug mus rau stilbene molecule, hu ua Rosewood cog genus.
VI.Cov nyhuv hauv Kev Kho Hniav:
1. inhibit melanin. Pterostilbene muaj lub peev xwm muaj zog los tiv thaiv melanin, txawm tias dhau ntawm glabridin, hu ua "whitening gold", thiab muaj cov nyhuv freckle tshem tawm tau zoo heev.
2. inhibit tyrosinase. Tyrosinase yog qhov tseem ceeb enzyme ntawm melanin synthesis. Glabridin, hu ua "whitening gold", muaj qhov qis tshaj ib nrab inhibitory concentration IC50 tus nqi ntawm tyrosinase ntawm tag nrho cov khoom. Pterostilbene yog me ntsis qis dua glabridin, tab sis nws yog obviously superior rau lwm cov ntaub ntawv whitening raw li VC thiab arbutin.
3. Antioxidant. Dawb radicals nyob txhua qhov chaw, ob qho tib si sab hauv thiab sab nraud. Thaum cov dawb radicals nyob rau hauv tib neeg lub cev muaj ntau tshaj ib tug tej yam, lawv yuav ua rau ntau yam kev puas tsuaj rau peb lub cev. Dawb radicals nyob rau hauv cov huab cua yuav ncaj qha mus rau ntawm daim tawv nqaij, txeeb electrons los ntawm daim tawv nqaij hlwb, ua rau daim tawv nqaij poob nws elasticity, ua rau tawv tawv thiab wrinkles, thiab aggravate lub oxidative kev puas tsuaj ntawm daim tawv nqaij. Pterostilbene muaj cov tshuaj antioxidant zoo heev. Nws cov pa oxygen dawb radical absorption ORAC tus nqi yog siab li 12508μmol trolox sib npaug / g, uas yog 3 npaug ntawm Vc thiab glabridin; nws lub peev xwm los inhibit DPPH dawb radicals yog qis dua li ntawm Vc.
4. Tiv thaiv ultraviolet rays. Cov pterostilbene-kho thiab tsis kho nas fibroblasts feem ntau irradiated nrog ultraviolet rays, thiab lub peev xwm ntawm pterostilbene tiv thaiv ultraviolet rays tau paub los ntawm kev kuaj xyuas cov kev ua ntawm fibroblasts.
5. Anti-inflammatory nyhuv. Muaj qee qhov kev puas tsuaj rau tib neeg lub cev, xws li elastase thiab collagenase, uas yuav rhuav tshem cov qauv ntawm daim tawv nqaij, ua rau daim tawv nqaij xoob thiab laus. Pterostilbene muaj ob lub peev xwm inhibitory, inhibiting ob lub enzymes puas tsuaj tib lub sijhawm.
6. Anti-glycation. Cov tshuaj tiv thaiv glycation hauv thaj tsam ntawm daim tawv nqaij yog hais txog kev sib sau ntau dhau ntawm kev txo cov suab thaj hauv daim tawv nqaij vim tias cov metabolism qeeb. Cov suab thaj yog ib qho yooj yim rau react nrog collagen thiab elastin nyob rau hauv daim tawv nqaij los tsim irreversible xim av terminal glycation khoom (AGEs). Collagen los yog elastin yog denatured thiab cross-linked, thiab daim tawv nqaij ua wrinkled, ntxhib thiab tsaus daj. Pterostilbene tuaj yeem txo cov ntsiab lus ntawm cov protein sib txuas, inhibit qhov glycation cov tshuaj tiv thaiv, txo cov AGEs, thiab ua tiav cov nyhuv ntawm dispelling jaundice thiab tiv thaiv kev laus.
