Taw qhia thiab siv CAS97-53-0|EUGENOL
Kev siv eugenol (97-53-0):
Cov khoom no muaj ib tug muaj zog dianthus musk tsw thiab yog lub hauv paus rau blending Kangji essences. Nws yog siv rau hauv kev sib xyaw ntawm cov tshuaj pleev ib ce, xab npum, zaub mov thiab lwm yam tshuaj tsw qab.
Nws yog tsuas yog siv los npaj mint, txiv ntseej, ntsim zaub mov flavors thiab haus luam yeeb tsw. Qhov ntau npaum li cas yog raws li kev xav tau ntau lawm. Cov koob tshuaj hauv cov nqaij yog 40~ 2000mg / kg; hauv cov pos hniav 500mg / kg; nyob rau hauv condiments 9.6 ~ 100 mg / kg; 33 mg / kg hauv cov khoom ci; 32 mg / kg hauv khoom qab zib; 3.1 mg / kg hauv dej txias; 1.4 mg / kg hauv cov dej qab zib; 0.6 mg / kg hauv puddings. Nws muaj zog bactericidal zog, yuav siv tau raws li ib tug zos analgesic rau cov hniav caries, thiab muaj ib tug antiseptic nyhuv. Eugenol yog ib qho nruab nrab ntawm qee lwm cov txuj lom, thiab nws cov derivatives suav nrog isoeugenol, methyl eugenol, methyl isoeugenol, acetyl eugenol, acetyl eugenol, benzyl isoeugenol, thiab lwm yam.
Thaum eugenol yog rhuab nyob rau hauv poov tshuaj hydroxide, ob daim ntawv cog lus ntawm pawg propenyl rearranges thiab ua ib pawg -propenyl conjugated nrog lub nplhaib benzene, yog li tau txais isoeugenol. Tom qab acetylation thiab oxidation me ntsis, -propenyl pawg tau txais. Cov pab pawg propylene tau tawg kom tau txais vanillin, uas yog cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob tseem ceeb. Eugenol kuj tseem siv tau los ua isoniazid, ib qho tshuaj tshwj xeeb rau kev kho mob tuberculosis.
Txoj kev npaj ntawm eugenol (97-53-0):
Lilac, zoo ib yam nrog clove, yog paj paj ntawm genus Syzygium ntawm tsev neeg Myrtaceae. Muaj ntau tshaj 500 hom Syzygium nyob hauv lub ntiaj teb thiab txog 72 hom hauv Suav teb.
Lilac yog cov nroj tsuag hav zoov hav zoov hav zoov, tsim rau cov huab cua sov thiab av noo, tsis tiv taus txias, thiab xav tau dej nag ntau; tob, fertile, zoo-drained loam yog nyiam. Nws yog feem ntau sau los ntawm lub Cuaj Hli mus txog Lub Peb Hlis ntawm xyoo tom ntej thaum lub paj buds tig los ntawm ntsuab mus rau liab. Tom qab sau qoob, tshem cov peduncles thiab qhuav lawv nyob rau hauv lub hnub.
Nws ib txwm muaj nyob rau hauv ntau yam roj yam tseem ceeb, tshwj xeeb tshaj yog cov roj clove (muaj 80%), clove basil roj (muaj 60%), thiab bay nplooj roj (muaj 80%). Nws yog ntau tshaj nyob rau hauv violet roj, camphor roj, acacia roj, Ob leeg muaj nyob rau hauv ylang ylang roj. Kev lag luam, nws tuaj yeem raug cais tawm los ntawm cov roj yam tseem ceeb, lossis nws tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm o-methoxyphenol thiab allyl bromide, ua raws li cov cua sov thiab rov kho dua.
1. Natural tseem ceeb roj cais txoj kev: Siv perennial subshrub clove thiab basil li raw khoom, ib tug sib tov ntawm tseem ceeb roj thiab dej yog tau los ntawm chav distillation. Ntxiv 20% sodium hydroxide rau cov roj-dej sib tov, thiab tom qab ntawd ua cov dej distillation kom tshem tawm cov khoom tsis yog acidic. Ntxiv cov sodium eugenol tov rau 30% sulfuric acid ntawm 50 degree, do thiab neutralize kom txog thaum Ph=2 ~ 3 (dej txheej). Tom qab sawv, cov roj clove crude nyob rau hauv qis txheej yog sib cais thiab distilled nyob rau hauv lub siab txo kom tau cov khoom tiav ntawm eugenol.
2. Txoj kev siv tshuaj lom neeg: Ntxiv allyl bromide, o-methoxyphenol, anhydrous acetone thiab anhydrous potassium carbonate rau hauv cov tshuaj tiv thaiv kettle, thiab cua sov thiab reflux rau ob peb teev. Tom qab txias, dilute nrog dej thiab extract nrog ether. Cov extract tau ntxuav nrog 10% sodium hydroxide thiab qhuav dhau anhydrous potassium carbonate. Tom qab lub siab ib txwm distillation kom rov qab tau ether thiab acetone, ua lub tshuab nqus tsev distillation los sau cov feem ntawm 110 ~ 113 degree (1600Pa), uas yog o-methoxyphenyl allyl ether. Boil thiab reflux rau 1 teev thiab tom qab ntawd txias. Lub resulting roj yog yaj nyob rau hauv diethyl ether, thiab ces muab rho tawm nrog 10% sodium hydroxide tov. Cov extract yog acidified nrog hydrochloric acid thiab muab rho tawm nrog diethyl ether. Cov extract yog qhuav nrog anhydrous sodium sulfate, thiab ether yog zoo los ntawm distillation nyob rau hauv ib txwm siab kom tau cov khoom tiav ntawm clove hmoov. Cov khoom tiav tuaj yeem tau txais los ntawm reacting o-methoxyphenol thiab allyl chloride nyob rau hauv catalysis ntawm metallic tooj liab thiab cov kauj ruam tom ntej ntawm 100 degree.
