Teb thiab Piav Qhia: Methanol yog cov kuab tshuaj zoo rau kev rho tawm thiab nws tau nquag siv hauv biology vim nws qhov sib txawv. Nws muaj peev xwm rho tawm ob leeg lipophilic

Tib neeg kuj nug, vim li cas methanol yog cov kuab tshuaj zoo dua li ethanol?

Ethanol tau paub tias yog qhov zoo hnyav rau polyphenol rho tawm thiab muaj kev nyab xeeb rau tib neeg noj. Methanol tau pom feem ntau ua kom muaj txiaj ntsig zoo dua hauv kev rho tawm ntawm qhov hnyav molecular hnyav polyphenols, qhov aqueous acetone yog qhov zoo rau kev rho tawm ntawm qhov hnyav molecular hnyav flavanols [6].

Vim li cas methanol thiab ethanol tsis siv rau kev rho tawm? Qhov no txhais tau tias yog methanol tshem tawm 20% thiab ethanol tshem tawm 30%. Chemical engineer yuav xaiv methanol rau qhov laj thawj uas tau hais los saum no vim tias nws tuaj yeem rov siv cov hnyav tom qab sib cais. Yog li qee qhov khoom ntawm cov molecule txawm hais tias zoo dua rho tawm ntawm qhov ntsuas me me tsis muaj txiaj ntsig ntawm qhov loj dua.

Ib yam li ntawd, tib neeg nug, Methanol ua haujlwm li cas hauv kev rho tawm?

Feem ntau methanol yog siv rau rho tawm ntau yam sib xyaw ncov qaumteb tab sis qee pab pawg ntawm cov tsis sib txuas ncov qaumteb qabteb yog haum haum rau hauv methanol yog tias tsis yooj yim soluble. Yog li ntawd methanol feem ntau yog siv rau rho tawm ntawm bioactive sib txuas.

Cov kuab tshuaj twg yog siv hauv Soxhlet rho tawm?

Kev rho tawm nrog cov kuab tshuaj sib txawv xws li acetone , chloroform , ua tsaug dej , ethyl acetate hmoov , ua hexane thiab methanol tau ua tiav siv soxhlet apparatus. Luv luv, rau txhua 200 ml ntawm txhua qhov hnyav, 25 g ntawm cov nroj tsuag tawg nplooj tau siv hmoov rau soxhlet rho tawm.
