●Dab tsi yog Caffeic Acid?
Caffeic acid, tshuaj lub npe 3,4-dihydroxycinnamic acid (molecular mis C₉H₈O₄, CAS No. 331-39-5), yog ib tug natural phenolic acid compound dav pom nyob rau hauv cov nroj tsuag. Nws yog daj crystalline hmoov, me ntsis soluble nyob rau hauv dej txias, yooj yim soluble nyob rau hauv dej kub, ethanol thiab ethyl acetate, nrog ib tug melting point ntawm 194-213 ℃ (cov txheej txheem sib txawv), txiv kab ntxwv-liab hauv alkaline tov, thiab tsaus ntsuab nyob rau hauv kev sib cuag nrog ferric chloride.
Cov hauv paus extraction muaj xws li:
●Cov nroj tsuag tshuaj:Asteraceae Solidago, cinnamon, dandelion (muaj caffeic acid ≥ 0.02%), Ranunculaceae Cimicifuga rhizome;
●Txiv hmab txiv ntoo thiab zaub Resources:txiv qaub tev, blueberry, txiv apples, broccoli thiab cruciferous zaub;
●Cov khoom xyaw dej haus:kas fes taum (nyob rau hauv daim ntawv ntawm chlorogenic acid esters), caw (conjugated nrog tartaric acid).
Niaj hnub nimno technology siv supercritical CO₂ extraction los yog bio-enzymatic hydrolysis technology los purify caffeic acid los ntawm cov ntaub ntawv raw, nrog ib tug purity ntawm ntau tshaj 98%, ua tau raws li qib tshuaj thiab tshuaj pleev ib ce.
● Cov txiaj ntsig yog dab tsi Caffeic Acid?
Caffeic acid nthuav tawm ntau yam kev ua haujlwm lom neeg vim nws cov qauv o-diphenolic hydroxyl:
1. Antioxidant Thiab Anti-Inflammatory:
Nws muaj zog tshaj dawb radical scavenging muaj peev xwm ntawm hydrogenated cinnamic acid, thiab nws efficiency yog 4 npaug ntawm cov vitamin E. Nws blocks lipid peroxidation saw tshua los ntawm kev tsim quinone lug;
Inhibits leukotriene synthesis ( tswj kev tiv thaiv kab mob thiab o), txo UV-induced ntawm daim tawv nqaij DNA puas, thiab txo erythema Performance index los ntawm 50%.
2. Metabolic Thiab Cardiovascular Protection:
Caffeic acidInhibits low-density lipoprotein (LDL) oxidation thiab txo atherosclerotic plaque tsim;
Hauv kev sim noj zaub mov muaj rog rog, visceral rog tsub zuj zuj zuj zus los ntawm 30% thiab daim siab triglycerides txo los ntawm 40%.
3. Neuroprotection Thiab Anti-Tumor:
Txhim kho hippocampal insulin signaling, txhim kho kev nco ua haujlwm hauv Alzheimer tus kab mob qauv, thiab txo qis β-amyloid protein deposition;
inhibits kev loj hlob ntawm fibrosarcoma qog nqaij hlav cancer thiab inhibits qog loj hlob los ntawm kev txo cov DNA methylation.
4. Hemostasis Thiab Leukocyte nce:
Nws shrinks microvessels thiab txhim kho kev ua haujlwm ntawm coagulation yam. Nws yog siv nyob rau hauv kev kho mob phais hemostasis thiab leukopenia tom qab chemotherapy, nrog ib tug zoo npaum li cas ntawm 85%.
● Dab tsi yog Daim Ntawv Thov Ntawm Caffeic Acid ?
Kev siv caffeic acid npog ntau qhov chaw:
1. Tshuaj:caffeic acid ntsiav tshuaj (hemostasis, ntshav dawb nce), tshuaj tiv thaiv qog nqaij hlav (succinic acid theem II soj ntsuam)
2. Tshuaj pleev ib ce:tshuaj pleev thaiv hnub (synergistic zinc oxide kom nce SPF tus nqi), whitening essence (inhibit tyrosinase, melanin inhibition tus nqi 80%)
3. Kev lag luam zaub mov:natural preservatives (txhim ntses lipid oxidation), ua haujlwm dej haus (anti-oxidation thiab anti-inflammatory), synergistic siv ascorbic acid
4. Kev Ua Liaj Ua Teb Thiab Kev Tiv Thaiv Ib puag ncig:ecological tshuaj tua kab (inhibit paj rwb bollworm protease), wool hloov kho (antioxidant zog nce los ntawm 75%)
●Kev siv thiab kev nyab xeeb kev caiNtawmCaffeic Acid
Tshuaj noj ntau npaum:Caffeic acid ntsiav tshuaj: 0.1-0.3g ib zaug, 3 zaug hauv ib hnub, 14 hnub raws li kev kho mob, platelet suav yuav tsum tau saib xyuas (txo thaum> 100 × 10⁹ / L, yuav tsum tau sab laj nrog kws kho mob ua ntej siv);
Contraindications:Contraindicated rau cov poj niam cev xeeb tub thiab cov neeg mob uas muaj lub xeev hypercoagulable; siv nrog ceev faj nyob rau hauv cov neeg mob uas muaj lub siab tsis ua hauj lwm thiab gastrointestinal ulcers.
Cosmetic additives:0.5% -2% ntxiv rau cov khoom siv ntxuav hniav dawb, ua ntej yaj hauv ethanol thiab tom qab ntawd ntxiv rau hauv aqueous matrix kom tsis txhob agglomeration.
Cov cai cia khoom:kaw hauv qhov chaw tsaus, txias ntawm 2-8 ℃, siv tau rau 2 xyoos (kua npaj yuav tsum tau tiv thaiv oxidation thiab degradation)
