I-Salicin, eyaziwa nangokuthi i-willow alcohol kanye ne-salicin, inefomula i-C13H18O7. Itholakala kabanzi emagxolweni nasemaqabungeni ezitshalo eziningi ze-willow kanye ne-poplar, isibonelo, amagxolo e-willow ansomi angaqukatha i-salicin efika ku-25%. Ingenziwa ngokwenziwa kwamakhemikhali. I-Salicinogen kanye ne-salicylic acid zingatholakala emchameni imizuzu eyi-15-30 ngemva kokuphathwa ngomlomo, ngakho-ke, inemiphumela yokulwa nokuvuvukala, ukudambisa ubuhlungu kanye nokuvuvukala, ukulwa namathambo. Ngenxa yokuthi ukuguqulwa okunjalo akuhlali njalo, ngakho-ke inani layo lokwelapha liphansi kunele-salicylic acid. Iphinde ibe nomphumela obabayo wesisu kanye nowokubulala izinzwa wendawo. Ingasetshenziswa futhi njenge-reagent yamakhemikhali. Kuwukuhlakanipha ukukhetha i-China Active Salicin. SingabantuIfektri ye-Active Salicin; Umkhiqizi we-Active Salicin; Amafektri e-Active Salicin.

I-Salicin iyikristalu emhlophe; ukunambitheka okubabayo; iphuzu lokuncibilika 199-202℃, ukujikeleza okuthile [α]-45.6° (0.6g/100cm3 i-ethanol engenamanzi); 1g incibilika emanzini angu-23ml, amanzi abilayo angu-3ml, i-ethanol engu-90ml, i-ethanol engu-30ml engu-60°, incibilika kwisisombululo se-alkali, i-pyridine kanye ne-glacial acetic acid, ayincibiliki ku-ether, i-chloroform. Isixazululo samanzi sibonisa ukungakhethi ephepheni le-litmus. Alikho iqembu le-phenolic hydroxyl yamahhala ku-molecule, linge-phenolic glycosides. I-hydrolyzed yi-dilute acid noma i-enzyme ye-almond ebabayo, ingakhiqiza i-glucose kanye ne-salicyl alcohol. Ifomula yama-molecule ye-salicyl alcohol yi-C7H8O2; iyikristalu yenaliti engenambala ye-rhomboidal; iphuzu lokuncibilika 86 ~ 87℃; i-sublimation ku-100℃; incibilika emanzini nase-benzene, incibilika kalula ku-ethanol, i-ether kanye ne-chloroform; umbala obomvu uma uhlangana ne-sulfuric acid.

I-Salicin inemiphumela yokulwa nokuvuvukala kanye neyokudambisa ubuhlungu, futhi yayisetshenziswa ekwelapheni i-rheumatism esikhathini esidlule, kodwa isithathelwe indawo eminye imithi. Ngenxa yokuthi ingakhiqiza utshwala be-salicylic ngemva kwe-hydrolysis, ingafakwa kalula e-oxidized ukuze ikhiqize i-salicylic acid, ngakho-ke yayiwumthombo oyinhloko wemithi ye-salicylic acid yokwenziwa, futhi manje imboni yezokwelapha isithathe indlela yokwenziwa ukuze ikhiqize i-salicylic acid.

I-Salicin, isithako esilwa nokuvuvukala, esaziwa nangokuthi i-Willowbark extract, inezakhiwo zokulwa nokuvuvukala ezithatha indawo ye-salicylic acid, ebangela ukucasuka kwesikhumba.

Ukusebenza kahle kwe-salicin

Ukusebenza kahle kwe-salicin: I-Salicin iyi-ejenti yokulwa nokuvuvukala eyenziwe ngegxolo le-willow, eliguqulwa ngumzimba libe yi-salicylic acid. Ngokusho kwencazelo ye-Wikipedia, ifana ngokwemvelo ne-aspirin futhi isetshenziswa ngokwesiko ukwelapha amanxeba nobuhlungu bemisipha. Nakuba ukuguqulwa kwe-salicin ibe yi-salicylic acid emzimbeni womuntu kudinga ama-enzyme, i-salicin yangaphandle nayo iyasebenza ngoba inezakhiwo ezifanayo zokulwa nokuvuvukala ne-aspirin futhi isetshenziswa ekukhiqizeni imikhiqizo ye-acne ukuze kuncishiswe i-acne nezinye izinkinga zesikhumba.
