Lub peev xwm ntawm qee cov txiv hmab txiv ntoo thiab zaub los txhim kho kev ua haujlwm ntawm qee lub cev hauv nruab nrog cev tau paub ntev los ntawm noob neej. Raws li kev tshawb fawb, nws tau paub tias cov khoom muaj txiaj ntsig no muaj los ntawm cov khoom tshwj xeeb uas muaj nyob hauv cov nroj tsuag thiab ua lub luag haujlwm tseem ceeb hauv lawv lub neej. Thiab cov tshuaj no hu ua "flavonoid". Nws yog dab tsi thiab nws cuam tshuam li cas rau tib neeg lub cev tuaj yeem pom hauv kab lus no.
keeb kwm me ntsis
Cov kws kho mob thaum ub tau siv cov khoom muaj txiaj ntsig ntawm qee yam zaub thiab txiv hmab txiv ntoo los kho ntau yam kab mob. Txawm li cas los xij, lawv tseem tsis tau xav txog cov lus nug ntawm cov tshuaj dab tsi uas ua rau cov nroj tsuag no ua rau cov khoom muaj peev xwm kho tau ib qho mob. Thawj thawj zaug, cov lus nug, flavonoid - nws yog dab tsi, tau teb los ntawm Nobel nqi zog yeej nyob rau hauv cov tshuaj thiab physiology Albert de Szent-Györgyi nyob rau hauvXyoo 1936. Nws txoj kev tshawb fawb tsom mus rau cov flavonoids pom hauv cov kua txob liab. Albert de Szent-Györgyi nrhiav pom tias noj cov zaub no pab ntxiv dag zog rau cov phab ntsa ntawm cov hlab ntsha vim muaj qee cov xim liab liab, thiab hu ua vitamin P. Txawm li cas los xij, lub npe no tsis muaj cag. Ntxiv mus, nyob rau tsib caug xyoo tom ntej no, lub ntsiab lus no tsis muaj kev txaus siab rau kev tshawb fawb, tab sis nyob rau hauv thaum ntxov 90s ntawm lub xyoo pua xeem, ib tug tshiab boom pib pom. Qhov no yog vim qhov tseeb tias ib pawg neeg Asmeskas cov kws tshawb fawb tau tshawb pom cov khoom antioxidant ntawm flavonoids pom hauv qee yam zaub thiab txiv hmab txiv ntoo. Tom qab ntawd, nws tau txiav txim siab siv cov txiaj ntsig zoo ntawm cov nroj tsuag no kom tsis txhob muaj cov dawb radicals.
YDab tsi yog flavonoid?
Ib pawg ntawm cov tshuaj muaj nyob hauv zaub, txiv hmab txiv ntoo, txiv ntoo thiab tshuaj ntsuab uas cuam tshuam rau kev ua haujlwm ntawm cov enzymes hauv lub cev hu ua flavonoids. Lawv tau dav siv nyob rau hauv ob qho tib si pej xeem thiab tsoos tshuaj, pharmacology. Cov tshuaj no kuj muaj lub luag haujlwm rau cov xim ntawm cov txiv hmab txiv ntoo, lawv koom nrog hauv photosynthesis. Dab tsi yog flavonoid? Qhov no yog dab tsi - vitamin lossis lwm yam? Qhov no yog heterocyclic compound. Nws tsis zoo soluble hauv dej, nws tuaj yeem muaj xim sib txawv (daj, liab, txiv kab ntxwv, thiab lwm yam). Flavonoids tseem tuaj yeem hu ua ntuj cog dyes. Txawm li cas los xij, lawv tsuas pom muaj nyob hauv cov nroj tsuag xwb, tab sis tsis muaj nyob hauv lub cev tsiaj.
Flavonoids: kev faib tawm thiab hom
Hnub no, cov kws tshawb fawb tau txheeb xyuas ntau dua 6500 flavonoids, uas tau muab faib ua 24 pawg. Ntawm lawv yog lipophilic thiab dej-soluble compounds. Ib txhia ntawm cov pab pawg no yog pigments ntawm zaub keeb kwm. Lawv txiav txim siab xim ntawm cov txiv hmab txiv ntoo ntawm cov nroj tsuag thiab paj. Nyob ntawm qhov degree ntawm oxidation ntawm 3-carbon fragment, muaj cov nram qab no cov chav kawm ntawm flavonoid tebchaw:
- leukoanthocyanidins (leukocyanidin, leukodelphinidin, leukopelargonidin);
- catechins;
- flavonones;
- chalcones;
- Ydihydrochalcones;
- flavononols;
- anthocyanins thiab anthocyanidins;
- aurons;
- flavonols (bioflavonoids);
- Yisoflavones.
Ntawm no lub npe nrov tshaj plaws ntawm cov flavonoids hnub no yog rutin los yog, raws li nws yog hu ua lwm yam, vitamin C2, los yog R. Nws yog nto moo rau dab tsi? Cov tshuaj no muaj cov khoom tshwj xeeb vasoconstrictive. Rau qhov no, nws (los yog nws cov hluavtaws analogue) yog ib qho ntawm cov khoom siv ntawm ntau cov tshuaj, piv txwv li, rutin yog ib feem ntawm cov tshuaj Ascorutinum, tsim los ua kom cov elasticity ntawm capillaries thiab cov hlab ntsha.
Flavonoids: kev ua ntawm lub cev
Cov khoom muaj txiaj ntsig ntawm flavonoids rau tib neeg lub cev tsis txwv rau kev txhawb nqa vascular. Tsis tas li ntawd, lawv muaj cov teebmeem tseem ceeb xws li:
-
flavonoids hauv cov nroj tsuag dej;
- venotonic;
- Yvasodilator;
- Yantiatherosclerotic;
- membrane stabilizing;
- antiallergic;
- antihypertensive;
- anti-inflammatory;
- cardioprotective;
- immunomodulating;
- tshuaj tiv thaiv kab mob;
- Yantioxidant;
- detoxifying;
- antihypoxant;
- zoo li estrogen thiab lwm yam
Raws li qhov no, peb tuaj yeem hais tias flavonoids muaj antioxidant, tiv thaiv hluav taws xob, antispasmodic, anti-ulcer, antitumor, anti-inflammatory, qhov txhab kho, hypotensive, estrogenic, bactericidal, diuretic zog, thiab lwm yam.
khoom siv tau zoo
Raws li koj tuaj yeem pom, flavonoids muaj txiaj ntsig thiab tseem tsim nyog rau tib neeg. Lawv pab txhawb rau kev ua haujlwm ntawm lub cev, thiab lawv qhov kev ua haujlwm tsis yog kev txhoj puab heev. Paub txog lawv cov txiaj ntsig zoo, nws yooj yim rau nws tus kheej los pab koj lub cev hauv kev daws qee qhov teeb meem. Yog li, piv txwv li, vim muaj cov nyhuv antioxidant, liab caw (nyob rau hauv moderation) yog pom zoo rau cov neeg nyob hauv ib cheeb tsam uas muaj hluav taws xob ntau ntxiv. Txawm li cas los xij, flavonoids, cov nyhuv ntawm lub cev uas tau raug tshawb fawb pov thawj, txawm li cas los xij, tsis yog cov tshuaj kho mob tseem ceeb. Lawv tsuas tuaj yeem dhau los ua tus pabcuam, nrog rau kev kho lub ntsiab. Txawm li cas los xij, txawm tias qhov tseeb tias flavonoids hauv cov nroj tsuag muaj ntau txaus, txawm li cas los xij, lawv feem ntau tsis ruaj khov. Yog tias ua tsis raug, lawv yuav tuag.
Khoom noj muaj flavonoids
Hnub no, kev npaj muaj flavonoids tuaj yeem yuav ntawm lub tsev muag tshuaj lossis xaj online. Txawm li cas los xij, nws muaj txiaj ntsig ntau dua los noj zaub thiab txiv hmab txiv ntoo, uas suav nrog cov khoom muaj txiaj ntsig no. Cov flavonoids nyob qhov twg? Ntawm no yog qhov tsis tiavdaim ntawv teev cov khoom noj uas muaj cov khoom muaj txiaj ntsig:
- cocoa;
- tshuaj yej, tshwj xeeb tshaj yog tshuaj yej ntsuab (flavones thiab catechins);
- liab txiv hmab txiv ntoo thiab cawv liab;
- Apricots, plums, txiv apples, txiv duaj, txiv duaj, quince, thiab lwm yam;
- berries: cherry, blueberry, raspberry, blueberry, strawberry, dub thiab liab currant, dub mulberry, hawthorn, barberry, thiab lwm yam;
- citrus txiv hmab txiv ntoo: txiv qaub, txiv kab ntxwv, txiv kab ntxwv, txiv kab ntxwv (flavonones, flavones);
- zaub: zaub qhwv, carrots, beets, eggplant, thiab lwm yam.
Flavonoids yog cov zaub thiab txiv hmab txiv ntoo nplua nuj tshaj plaws uas muaj xim burgundy lossis ntshav liab, nrog rau cov txiv hmab txiv ntoo qus. Nws tau raug pov thawj tias yav tas los cov ntsiab lus ntawm cov xim ntuj yog ntau dua thiab cov no feem ntau yog leukoanthocyanidins, thaum rosaceae muaj flavones, thiab legumes muaj isoflavonoids.
YYuav ua li cas noj flavonoids?
Tam sim no, tsis tshua muaj leej twg tsis tau hnov lo lus "flavonoid", nws yog dab tsi thiab nws yog "noj nrog". Nyob rau hauv xyoo tas los no, cov tshuaj no tau ua kom pom tseeb ntawm cov kws kho mob, uas tau siv ntau ntxiv rau kev tsim tshuaj. Los ntawm txoj kev, ntau tus kws tshawb fawb hauv daim teb no "kab mob" nrog lub tswv yim los tsim lub npe hu ua elixir ntawm cov hluas, siv tag nrho cov tib yam flavonoids. Cov txiaj ntsig ntawm cov tshuaj no rau tib neeg lub cev yog pom tseeb. Txawm li cas los xij, lawv cov khoom muaj txiaj ntsig puas tuaj yeem tiv thaiv cov cim ntawm kev laus? Txawm li cas los xij, lawv twv yuav raug hu ua qhov zoo tshaj qhov ua phem. Yog vim li casKev siv zaub, txiv hmab txiv ntoo, txiv hmab txiv ntoo, zaub ntsuab nplua nuj nyob rau hauv flavonoids yuav tsuas nyiam koj kev noj qab haus huv, ua rau koj lub cev muaj zog. Koj yuav xav tias hluas dua, tshiab dua, ceeb toom thiab noj qab nyob zoo. Tsis tas li ntawd, cov khoom noj no tuaj yeem noj tsis tau qhov ntau. Ntseeg kuv, tsis muaj kev noj ntau dhau ntawm flavonoids hem koj, tau kawg, yog tias peb tsis tham txog cov tshuaj bioactive. Tsis muaj teeb meem lawv yuav tsum tau siv yam tsis muaj kev pom zoo los ntawm kws kho mob lossis tsis tau kawm cov lus qhia, tshwj xeeb tshaj yog cov khoom "dosage".
