Cistanche(Herba Cistanches) feem ntau yog siv hauv cov tshuaj suav tshuaj los txhawb lub raum thiab tshuaj aphrodisiac. Cov kev tshawb fawb pharmacological niaj hnub ntseeg tias nws muaj kev tiv thaiv kev laus xws li kev ua kom lub neej ntev thiab ua kom lub neej ntev. Yog li ntawd, nws yog hu ua "desert ginseng. Tsiaj thwmsim qhia tau hais tias Cistanche deserticola muaj ib tug antihypertensive nyhuv, thiab nws cov pharmacological thiab tshuaj kev tshawb fawb tshuaj kuj tau qhia. Cistanche deserticola hauv tsev thiab txawv teb chaws muaj cov hydrocarbons, alkaloids, flavonoids, amino acids, phenethyl glycol, phenylpropanol glycol, iridoids, D mannitol, -sitosterol, polysaccharides, thiab inorganic kab kawm.
Nyem qhov no kom paub ntau yam khoom
Flavonoids, ntau tus neeg yuav paub, thiab ntau tus neeg yuav tsis tau hnov txog lawv. Qhov tseeb, nws yog ib qho kab uas xav tau los ntawm tib neeg lub cev. Niaj hnub no, kuv yuav tham txog cov flavonoids uas yuav tsum tau hais. Ntuj flavonoids feem ntau muaj nyob rau hauv daim ntawv ntawm glycosides, thiab ntau yam flavonoid glycosides tuaj yeem tsim los ntawm ntau hom, ntau, kev sib txuas txoj haujlwm, thiab kev sib txuas ntawm cov suab thaj. Flavonoids muaj dav nyob rau hauv qee cov nroj tsuag thiab berries nyob rau hauv cov xwm, muaj txog 4, 000 hom nyob rau hauv tag nrho, thiab lawv cov qauv molecular txawv, xws li rutin, hesperidin, quercetin, ntsuab tshuaj yej polyphenols, anthocyanins, anthocyanins, thiab lwm yam. Yog ib qho flavonoid. Cov suab thaj uas ua rau flavonoid glycosides suav nrog monosaccharides, disaccharides, trisaccharides, thiab acylated qab zib. Cov khoom flavonoid glycosides yog amorphous hmoov, thiab cov seem ntawm flavonoids feem ntau yog crystalline solids.
Flavonoids yog ib chav kawm ntawm cov xim daj tau los ntawm flavonoids (2-phenylchromone) raws li niam txiv nucleus. Ntawm lawv yog cov isomers ntawm flavonoids thiab lawv cov khoom txo qis hydrogenated, uas yog, cov khoom sib txuas nrog C6-C3-C6 raws li cov pa roj carbon monoxide. Flavonoids yog dav faib nyob rau hauv cov nroj tsuag lub nceeg vaj. Feem ntau ntawm lawv tau ua ke nrog cov suab thaj hauv cov nroj tsuag los tsim glycosides lossis carbon suab thaj, thiab qee qhov kuj muaj nyob hauv daim ntawv dawb. Lub nucleus ntawm ntuj flavonoids feem ntau muaj cov khoom siv xws li hydroxyl, methoxy, hydrocarbyloxy, thiab isopentenyloxy. Vim muaj cov auxochromes, hom tshuaj no feem ntau yog daj. Thiab vim hais tias cov pa atom ntawm lub nplhaib -pyridone nyob rau hauv lub molecule tuaj yeem tsim cov ntsev nrog cov kua qaub uas muaj zog, nws tsis muaj zog, yog li nws tau raug hu ua flavonoid compound.
Feem ntau cov flavonoids yog daj lossis xim daj, nrog 2-phenyl chromone ua cov qauv tseem ceeb, thiab feem ntau ntawm cov molecules muaj ketone pawg, yog li lawv hu ua tag nrho flavonoids, feem ntau pom hauv cov khoom noj xws li txiv hmab txiv ntoo, zaub, taum. , thiab tshuaj yej. hauv cov nroj tsuag kev sib deev. Tag nrho cov flavonoids yog cov khoom noj tseem ceeb rau tib neeg lub cev, tab sis tib neeg lub cev tsis tuaj yeem tsim lawv los ntawm nws tus kheej thiab tuaj yeem tau txais los ntawm zaub mov xwb. Nws yog ib qho tseem ceeb rau kev tswj cov kev ua haujlwm physiological ntawm tib neeg lub cev. Feem ntau ntawm tag nrho cov flavonoids ntawm kev ua lag luam yog cov khoom xyaw ntuj muab rho tawm los ntawm qee cov nroj tsuag, thiab lawv cov txiaj ntsig kev noj qab haus huv tshwj xeeb yog qhov zoo heev. Naturally sourced bioflavonoids muaj qhov hnyav molecular me me thiab tuaj yeem nqus tau los ntawm lub cev sai. Muaj ntau ntau flavonoids nyob rau hauv taum, feem ntau yog taum isoflavones thiab lawv glycosides. Citrus txiv hmab txiv ntoo yog nplua nuj nyob rau hauv flavonoids. Tsis tas li ntawd, Suav tshuaj ntsuab xws li Acanthopanax senticosus thiab Shouwu Teng kuj muaj nplua nuj nyob rau hauv flavonoids. Tib neeg lub cev xav tau ntau yam khoom noj los tswj nws txoj kev noj qab haus huv. Cov khoom noj sib txawv muaj qhov sib txawv ntawm tib neeg lub cev.
Cov teebmeem ntawm flavonoids:
Flavonoids tuaj yeem txhim kho tib neeg kev tiv thaiv. Flavonoids muaj kev tiv thaiv zoo heev rau tib neegtiv thaiv kab mob. Nws tuaj yeem txhim kho kev ua haujlwm ntawm tib neeg lymphocytes, thiab tuaj yeem txo qhov kev tiv thaiv kab mob los ntawm hluav taws xob puas. Tag nrho cov flavonoids tuaj yeem txo cov kab mob kab mob thiab lwm yam kab mob thiab lwm yam. Kev puas tsuaj rau lub cev, feem ntau noj nruab nrab ntawm tag nrho cov flavonoids tuaj yeem txhim kho lub cev tiv thaiv kab mob.
Flavonoids tuaj yeem txhawb cov ntshav ncig.zoo txhim kho cov ntshav ncig ua haujlwm, thiab nws tuaj yeem txhim kho kev ua haujlwm ntawm tib neeg lymphocytes, tiv thaiv kev puas tsuaj ntawm cov kab mob, kab mob, thiab lwm yam kab mob pathogenic rau tib neeg lub cev. Nws tau hais tias noj nws nyob rau hauv ib qho me me tuaj yeem ua lub luag haujlwm hauv kev txhim kho lub cev tiv thaiv. Flavonoids muaj PAF anticoagulant yam, uas tuaj yeem tiv thaiv kev tsim cov ntshav txhaws thiab txo cov ntsiab lus ntawm cov roj cholesterol hauv cov ntshav, yog li flavonoids tsis tuaj yeem txo qhov tshwm sim ntawm cov kab mob plawv thiab cerebrovascular, tab sis kuj rau qee cov neeg uas twb raug kev txom nyem los ntawm cov hlab plawv thiab. kab mob cerebrovascular. Kev noj nruab nrab kuj muaj qee yam kev txhim kho.
Flavonoids tuaj yeem txhim kho tib neeg lub peev xwm hematopoietic. Flavonoids yog cov tshuaj lom neeg lom neeg, uas tuaj yeem tswj hwm lub cev hematopoietic kev ua haujlwm thiab ua rau kom muaj kev tso tawm ntawm cov khoom los ntawm cov hlwb ntsig txog hematopoietic. Tsis tas li ntawd, tag nrho cov flavonoids tseem tuaj yeem txhawb kev rov qab los ntawm cov kab mob hematopoietic, ua rau lub cev muaj peev xwm tshem tawm ROS (cov kab mob reactive oxygen), thiab txo cov ntaub so ntswg hematopoietic. Nws kuj tseem txhim kho lub cev muaj peev xwm hematopoietic, uas muaj txiaj ntsig zoo rau kev tiv thaiv kab mob ntshav qab zib.
Flavonoids tuaj yeem tiv thaiv DNA thiab tiv thaiv kev hloov ntawm noob. Flavonoids tuaj yeem tiv thaiv DNA hauv tib neeg lub cev los ntawm hluav taws xob puas tsuaj, thiab tseem tuaj yeem txo qhov kev tawm tsam thiab kev puas tsuaj ntawm cov dawb radicals rau DNA, yog li zam qhov tshwm sim ntawm ntau yam tsis zoo xws li DNA tawg, noob hloov pauv, chromosomal recombination, thiab cell tuag. . Nws muaj cov txiaj ntsig zoo inhibitory ntawm cell carcinogenesis thiab qog nqaij hlav qog noj ntshav.
Tsis tas li ntawd, flavonoids muaj ntau yam kev ua ub no hauv tib neeg lub cev, uas tuaj yeem txo cov ntshav qab zib, tiv thaiv kab mob plawv, tiv thaiv hepatotoxicity, tiv thaiv kab mob, tiv thaiv mob hawb pob, tiv thaiv kab mob, thiab tiv thaiv kab mob, antispasmodic, anti-oxidative. , anti-depressant, anti-neurodegenerative kab mob, thiab lwm yam. Ob leeg ua haujlwm.
Qee cov khoom xyaw nquag muaj nyob rau hauv flavonoids muaj cov nyhuv antihistamine muaj zog thiab tuaj yeem cuam tshuam cov exudation ntawm cov tshuaj inflammatory, txhawb kev rov zoo ntawm cov qhov txhab nyob rau hauv cov cheeb tsam cuam tshuam, thiab muaj qee yam kev mob analgesic. Nws yog haum rau qee cov neeg uas muaj qhov txhab thiab tawv nqaij rhiab. Nws tau hais tias noj nws nyob rau hauv ib qho me me tuaj yeem txhim kho cov tsos mob ntawm kev tsis xis nyob zoo heev. Flavonoids yog cov tshuaj tiv thaiv antioxidant uas muaj zog antioxidant, uas tuaj yeem tshem tawm cov pa dawb radicals uas ua rau kev laus thiab kab mob hauv lub cev, ncua kev degeneration thiab aging ntawm cov hlwb, tswj qhov sib npaug ntawm cov dej thiab roj hauv daim tawv nqaij, thiab muaj cov txiaj ntsig zoo. tiv thaiv kab mob. , Kev zoo nkauj thiab kev zoo nkauj, anti-aging nyhuv.
Hauv kev xaus, muaj ntau lub tebchaw ntawm cov nqi tshuaj nyob rau hauvflavonoids. Cov tshuaj no yog siv los tiv thaiv thiab kho cov kab mob plawv thiab paj hlwb, xws li txo cov hlab ntsha tawg, txhim kho permeability ntawm cov hlab ntsha, txo cov ntshav lipids thiab cov roj cholesterol, thiab tiv thaiv thiab kho mob ntshav siab, ntshav siab, mob plawv, kab mob plawv hauv cov neeg laus. . , angina pectoris, dilation ntawm coronary hlab ntsha, nce coronary txaus. Muaj ntau cov flavonoids muaj antitussive, expectorant, anti-asthmatic thiab antibacterial kev ua ub no, thiab kuj muaj lub siab tiv thaiv, detoxification, antifungal, kho mob ntawm tus kab mob siab thiab mob ntev, daim siab cirrhosis, thiabanti-dawb radicalthiabantioxidantteebmeem. Ntxiv rau qhov no, flavonoids kuj muaj cov nyhuv tib yam li phytoestrogens. Hauv kev tsim cov tsiaj txhu tsiaj txhu, kev siv cov flavonoids tuaj yeem txhim kho kev ua haujlwm ntawm tsiaj txhu, txhim kho tsiaj lub cev tiv thaiv kab mob, thiab txhim kho tsiaj lub cev tiv thaiv kab mob.
