Taw qhia

Levomenthol yog ib qho organic compound nrog lub npe tshuaj (-)-menthol. Nws muaj cov tshuaj tsw qab ntawm cov roj yam tseem ceeb thiab tsis muaj xim rau cov kua daj daj. Lub ntsiab tseem ceeb ntawm levomenthol yog menthol.

Levomenthol muaj ntau yam physiological thiab pharmacological kev ua ub no, xws li tshuaj tua kab mob, anti-inflammatory, analgesic, antipyretic, anthelmintic thiab lwm yam teebmeem.

Ib txoj hauv kev ua rau levomenthol yog los ntawm distillation ntawm peppermint nroj tsuag. Lub mint nplooj thiab stems yog thawj zaug rhuab nyob rau hauv ib tug dej tseem, thiab thaum lub distillate txias, ib tug extract uas muaj levomenthol yog tau. Tom qab ntawd nws yog distilled rau purify, mloog zoo, thiab cais menthol.

Levomenthol muaj qee yam kev nyab xeeb, tab sis nws tseem yuav tsum tau ua tib zoo saib xyuas cov hauv qab no: tsis txhob cuam tshuam los yog nqus tau cov levomenthol siab los tiv thaiv kev ua xua lossis khaus khaus. Ib puag ncig zoo-ventilated yuav tsum tau khaws cia thaum siv. Tsis txhob sib cuag nrog lub qhov muag thiab tawv nqaij thiab dilute ua ntej siv.

Yav dhau los: 9-Decen-1-ol (CAS #13019-22-2)
