95% ethanol feem ntau yog siv rau hauv cov nroj tsuag rho tawm vim nws cov khoom tshwj xeeb uas ua rau nws zoo rau kev rho tawm ntau yam ntawm cov nroj tsuag sib txuas. Nov yog vim li cas:
1. Polarity Ntsuas
Ethanol yog ib qho hnyav polar, thiab nws cov polarity ntawm 95% concentration yog qhov zoo rau kev rho tawm ob qho tib si polar thiab non-polar compounds.
Nws muaj peev xwm yaj ib tug dav spectrum ntawm bioactive compounds xws li alkaloids, flavonoids, terpenes, thiab glycosides.
2. Cov ntsiab lus dej
5% dej hauv 95% ethanol txhim kho nws lub peev xwm los rho tawm cov dej-soluble compounds, xws li qee cov phenolics thiab glycosides, uas ntshiab ethanol yuav tsis yaj zoo.
Qhov kev sib npaug no tso cai rau kev nthuav tawm ntau dua ntawm cov khoom cog cog piv rau cov ntshiab ethanol lossis dej ib leeg.
3. Kev khaws cia ntawm Bioactive Compounds
Ethanol ntawm qhov concentration no minimizes lub degradation ntawm tshav kub-sensitive los yog tsis ruaj tsis khov bioactive compounds thaum lub sij hawm extraction.
4. Antimicrobial Properties
Ethanol ua raws li kev khaws cia, tiv thaiv kev loj hlob ntawm microbial nyob rau hauv extract, uas yog tshwj xeeb tshaj yog zoo rau kev cia mus ntev.
5. Volatility
Ethanol yog volatile, txhais tau tias nws tuaj yeem yooj yim tshem tawm ntawm cov extract los ntawm evaporation, tawm hauv qab cov concentrated cog tebchaw.
6. Kev Nyab Xeeb Khoom Noj thiab Tshuaj
Ethanol suav hais tias muaj kev nyab xeeb rau tib neeg noj hauv cov nyiaj tswj hwm thiab tau pom zoo siv rau hauv cov khoom noj thiab tshuaj.
Siv 95% ethanol kom ntseeg tau tias cov extracts tsim nyog rau kev siv xws li tshuaj ntsuab, tshuaj pleev ib ce, lossis khoom noj khoom haus.
7. Muaj thiab Nqi-zoo
95% ethanol yog dav muaj thiab nqi-zoo rau kev lag luam thiab kev kuaj-scale extractions.
Hauv cov ntsiab lus, kev sib xyaw ua ke ntawm polarity, cov ntsiab lus dej, kev ua haujlwm zoo hauv kev khaws cov khoom siv bioactive, thiab kev nyab xeeb rau tib neeg siv ua rau 95% ethanol yog qhov hnyav tshaj plaws rau kev cog qoob loo.
