Tam sim no, muaj ntau yam kev tshawb fawb txog cov txheej txheem hluavtaws, kev hloov kho cov qauv, tshuaj ntsuam xyuas tshuaj thiab kev tshawb nrhiav cov txheej txheem ntawm ursolic acid. Nyob rau hauv lub neej yav tom ntej, nws yog ib qho yuav tsum tau ua kom zoo dua cov txheej txheem ntawm ursolic acid los txhim kho nws purity thiab stability; txhawm rau tshawb nrhiav cov hom phiaj ua haujlwm thiab cov txheej txheem molecular ntawm ursolic acid kom nthuav tawm nws cov kev cuam tshuam thiab kev sib koom ua ke nrog lwm cov tshuaj; thiab txhawm rau ua qhov kev sim tshuaj ntxiv los xyuas nws cov txiaj ntsig tiag tiag thiab kev nyab xeeb ntawm tib neeg kev noj qab haus huv.

Nws muaj qhov tshwj xeeb tsw, loj thiab ci iab prismatic crystals nyob rau hauv anhydrous ethanol, thiab zoo plaub hau zoo li koob muaju muaju nyob rau hauv dilute ethanol. mp285 degree -288 degree , [ ]D20 ntxiv rau 66 degree (pyridine), yooj yim soluble hauv dioxane, pyridine, soluble hauv methanol, ethanol, butanol, butanone, me ntsis soluble hauv acetone, me ntsis soluble hauv benzene, chloroform, ether, insoluble hauv dej thiab roj av ether. Nws muaj ntau yam tshuaj lom neeg xws li sedative, tiv thaiv kab mob, tiv thaiv kab mob, tiv thaiv ntshav qab zib, tiv thaiv kab mob, thiab txo cov ntshav qab zib. Nyob rau hauv xyoo tas los no, nws tau pom tias muaj cov tshuaj tiv thaiv kab mob, tiv thaiv kab mob carcinogenic, inducing F9 teratoma cell txawv thiab anti-Chemicalbook angiogenesis cov teebmeem, uas yog heev yuav dhau los ua ib yam tshiab ntawm cov tshuaj tiv thaiv kab mob uas tsis muaj toxicity thiab high efficiency. . Tsis tas li ntawd, ursolic acid muaj cov txiaj ntsig zoo antioxidant thiab muaj zog antioxidant. Cov nyhuv antioxidant ntawm ursolic acid muaj txiaj ntsig zoo rau tib neeg los tiv thaiv kev laus, kev tshem tawm ntawm daim tawv nqaij thiab tshem tawm cov xim, yog li nws yog dav siv los ua cov khoom siv raw rau tshuaj thiab tshuaj pleev ib ce ntuj. Qee qhov kev sim tau pom tias ursolic acid tuaj yeem cuam tshuam 5-lipoxygenase thiab cyclooxygenase kev ua haujlwm hauv cov txheej txheem ntawm arachidonic acid metabolism thiab tiv thaiv prostaglandin thiab leukotriene tiam, uas yog vim li cas ursolic acid inhibits inflammatory teb thiab lipid peroxidation.

Loquat nplooj ursolic acid yog ib yam khoom ntuj uas feem ntau siv hauv tshuaj pleev ib ce thiab tshuaj.
