Taw qhia

Ligustral (tseem hu ua xanthrin) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm ligustral:

 

Zoo:

- Ligustrum yog cov xim tsis muaj xim rau yellowish crystalline khoom nrog cov ntxhiab tsw muaj zog ntawm chav sov.

- Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, ethers thiab ester solvents ntawm chav tsev kub, tab sis yuav luag insoluble hauv dej.

- Ligustral muaj volatility siab thiab yooj yim rau sublimate.

 

Siv:

- Nws yog dav siv nyob rau hauv kev lag luam tsw raws li ib tug natural nroj tsuag tsw muaj peev xwm impart aromatic zog rau cov khoom.

 

Txoj kev:

- Ligustrum tuaj yeem npaj tau los ntawm oxidation ntawm ligustrum (los ntawm ligustrum txiv hmab txiv ntoo). Ligustrum tau txais los ntawm kev ua haujlwm raws li qhov tsim nyog nrog tus neeg sawv cev oxidizing xws li acidic potassium permanganate lossis oxygen.

 

Cov ntaub ntawv kev nyab xeeb:

- Ligustaldehyde feem ntau suav hais tias yog ib qho chaw nyab xeeb, tab sis nws tseem xav tau kev saib xyuas kom raug.

-Nws yog ib qho ua rau khaus khaus uas yuav ua rau khaus qhov muag, tawv nqaij, thiab ua pa.

- Kev raug rau ligustrum yuav tsum raug zam thaum lub sijhawm ua haujlwm thiab yuav tsum ua kom muaj cua zoo.

- Thaum tuav ligustrum, hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg.
