Taw qhia
D salicin rau kev siv tshuaj cosemtic yog ib hom tshuaj organic nrog tshuaj mis mos ntawm C13H18O7. Nws yog xim siv lead ua tsis muaj xim lossis hmoov dawb. Nws yog soluble hauv dej, yooj yim soluble hauv dej npau npau, tsis yog soluble hauv ethanol (1:90), insoluble hauv ether lossis chloroform. Nws muaj cov khoom hygroscopic hauv kev hais daws teeb meem, pyridine lossis glacial acetic acid. Nws feem ntau pom muaj nyob hauv cov tawv ntoo thiab nplooj ntawm ntau cov nroj tsuag Salix thiab Populus.
Muaj nuj nqi
D salicin muaj cov nyhuv antipyretic thiab analgesic. Nws tau siv rau hauv kev kho mob rheumatism yav dhau los thiab tam sim no tau hloov los ntawm lwm cov tshuaj. Vim tias nws tuaj yeem tsim cov dej qab ntsev tom qab hydrolysis, nws yooj yim oxidized los ua cov tshuaj salicylic acid, yog li nws yog ib qho tseem ceeb ntawm cov tshuaj tua kab mob salicylic acid, thiab tam sim no txoj kev lag luam kws tshuaj tau siv cov txheej txheem hluavtaws los tsim salicylic acid.
