Salicin, tseem hu ua cawv willow thiab salicin, muaj cov mis C13H18O7. Nws pom dav hauv cov tawv ntoo thiab nplooj ntawm ntau cov nroj tsuag willow thiab poplar, piv txwv li, cov tawv ntoo ntawm cov paj yeeb willow tuaj yeem muaj txog li 25% salicin. Nws tuaj yeem ua los ntawm kev tsim tshuaj lom neeg. Salicinogen thiab salicylic acid tuaj yeem pom hauv cov zis 15-30 feeb tom qab noj, yog li ntawd, nws muaj cov teebmeem antipyretic, analgesic thiab anti-inflammatory, anti-rheumatic. Vim tias qhov kev hloov pauv no tsis tas li, yog li nws cov nqi kho mob qis dua li ntawm salicylic acid. Nws kuj muaj cov nyhuv mob plab thiab tshuaj loog hauv zos. Nws kuj tuaj yeem siv ua biochemical reagent. Nws yog qhov zoo los xaiv Tuam Tshoj Active Salicin. Peb yogLub Hoobkas Salicin Nquag; Chaw Tsim Khoom Salicin Nquag; Cov Hoobkas Salicin Nquag.

Salicin yog siv lead ua dawb; saj iab; melting point 199-202 ℃, kev sib hloov tshwj xeeb [α] -45.6 ° (0.6g / 100cm3 anhydrous ethanol); 1g soluble hauv 23ml dej, 3ml dej npau, 90ml ethanol, 30ml 60 ° ethanol, soluble hauv alkali kua, pyridine thiab glacial acetic acid, insoluble hauv ether, chloroform. Cov kua dej qhia tias tsis muaj zog rau daim ntawv litmus. Tsis muaj pawg phenolic hydroxyl dawb hauv lub molecule, koom nrog phenolic glycosides. Hydrolyzed los ntawm dilute acid lossis bitter almond enzyme, nws tuaj yeem tsim glucose thiab salicyl cawv. Cov mis molecular ntawm salicyl cawv yog C7H8O2; nws yog ib qho rhomboidal tsis muaj xim koob siv lead ua; melting point 86 ~ 87 ℃; sublimation ntawm 100 ℃; soluble hauv dej thiab benzene, yooj yim soluble hauv ethanol, ether thiab chloroform; xim liab thaum ntsib nrog sulfuric acid.

Salicin muaj cov teebmeem antipyretic thiab analgesic, thiab tau siv rau kev kho mob rheumatism yav dhau los, tab sis tau hloov los ntawm lwm cov tshuaj. Vim tias nws tuaj yeem tsim cov cawv salicylic tom qab hydrolysis, nws tuaj yeem yooj yim oxidized los tsim cov salicylic acid, yog li nws yog ib qho chaw tseem ceeb ntawm cov tshuaj salicylic acid synthetic, thiab tam sim no kev lag luam tshuaj tau siv txoj kev tsim cov salicylic acid.

Salicin, ib yam khoom xyaw tiv thaiv kev o, tseem hu ua Willowbark extract, muaj cov khoom tiv thaiv kev o uas yog ib qho hloov pauv zoo meej rau salicylic acid, uas ua rau khaus tawv nqaij.

Kev ua haujlwm ntawm salicin

Qhov ua tau zoo ntawm salicin: Salicin yog ib yam tshuaj tiv thaiv kev o uas ua los ntawm cov tawv ntoo willow, uas lub cev metabolized rau hauv salicylic acid. Raws li Wikipedia piav qhia, nws zoo ib yam li aspirin thiab ib txwm siv los kho cov qhov txhab thiab mob leeg. Txawm hais tias kev hloov pauv ntawm salicin mus rau salicylic acid hauv tib neeg lub cev xav tau cov enzymes, salicin sab nraud kuj ua haujlwm vim nws muaj cov khoom tiv thaiv kev o zoo ib yam li aspirin thiab siv rau hauv kev tsim cov khoom siv pob txuv kom txo cov pob txuv thiab lwm yam kev khaus ntawm daim tawv nqaij.
