Muaj Ultrasound Equipment

Nqe lus piav qhia:

Hauv kev rho tawm ultrasonic, lub zog siv hluav taws xob tsim los ntawm ultrasonic tsis yog siv rau cov qauv (raws li qhia hauv daim duab hauv qab no). Qhov no sonication tshwm sim hauv cavitation, tsim cov npuas me me los yog voids hauv cov kua uas tawg mus rau cov qauv khoom, uas ua rau muaj qhov kub thiab txias (~ 4500 degree) thiab siab (~ 50 MPa). Cov rog no tsim cov teebmeem xws li sonication, cuam tshuam ntawm cell membranes thiab extraction ntawm intracellular khoom.

1. Daim ntawv thov nyob rau hauv nicotine extraction

Cov nicotine tivthaiv hauv cov luam yeeb muaj txiaj ntsig zoo siv hauv kev ua liaj ua teb thiab tshuaj, thiab cov nicotine tivthaiv hauv cov luam yeeb tuaj yeem raug muab rho tawm los ntawm kev siv tshuab ultrasonic extraction. Nyob rau hauv no nam ntawm daim ntawv thov kev tshawb fawb, cov kws tshawb fawb tau tshawb xyuas qhov cuam tshuam ntawm yam xws li extractant concentration, solid-kua ratio, extraction time, and ultrasonic temperature on the extraction efficiency of nicotine components. 40% methanol li cov extractant, cov khoom-kua piv yog 1:20, lub sij hawm rho tawm yog 30 feeb, lub ultrasonic kub yog 150 degree, thiab cov extraction tus nqi ntawm nicotine yuav ncav cuag li 7%. Chu Zhibing thiab lwm tus siv 0.4% NaOH raws li cov extractant, cov khoom-kua piv yog 1:40, thiab ultrasonic extraction lub sij hawm ntawm chav tsev kub yog 4 teev, thiab cov extraction tus nqi ntawm nicotine yog 2.12%. 78% ethanol tau siv los ua cov extractant, cov khoom-kua piv yog 1: 5, lub sijhawm rho tawm yog 30min, thiab qhov kub ntawm ultrasonic yog 52 degree.

Qhov rho tawm ntawm nicotine yog 23.1mg / mL. Siv 95% ethanol nrog pH=4 raws li hnyav, khoom-kua piv 1:15, ultrasonic kub 80 degree extraction ob zaug, txhua 45min, nicotine extraction tus nqi tuaj yeem ncav cuag 95.42%, kev soj ntsuam sib piv qhia tau hais tias nws cov nyhuv extraction yog pom tseeb zoo dua. tshaj li cua sov Reflux extraction (tom kawg tsuas yog 84.79%).

2. Daim ntawv thov nyob rau hauv extraction ntawm tag nrho cov flavonoids los ntawm lotus noob lub plawv

Noj lotus noob lub plawv raws li cov khoom siv kuaj thiab ethanol tov raws li cov extractant, ultrasonic extraction txoj kev tau siv los ua ib qho kev xeem thiab L9 (34) orthogonal test los kawm txog cov teebmeem ntawm ethanol concentration, lub sij hawm rho tawm, solid-kua ratio thiab extraction kub. nyob rau hauv qhov extraction tus nqi ntawm tag nrho cov flavonoids. Kev npam. Cov txiaj ntsig tau pom tias qhov tseem ceeb cuam tshuam rau kev rho tawm ntawm tag nrho cov flavonoids hauv cov noob paj noob hlis yog qhov concentration ntawm ethanol, ua raws li qhov kub thiab txias, qhov sib piv ntawm cov kua dej, thiab lub sij hawm rho tawm ultrasonic; Qhov kev pom zoo rau kev rho tawm yog: ethanol concentration 60%, extraction kub 70 degree, Ratio 1:24g/mL, ultrasonic extraction lub sij hawm 30min, lub extraction tus nqi ntawm tag nrho cov flavonoids tau nyob rau hauv cov mob no yog 10.86mg / g .

3. Daim ntawv thov hauv Lycium barbarum polysaccharide extraction

Cov txheej txheem rho tawm ntawm Lycium barbarum polysaccharides tau muab rho tawm los ntawm ultrasonic yoj, cov ntsiab lus ntawm Lycium barbarum polysaccharides tau ntsuas los ntawm spectrophotometric colorimetry, thiab cov txheej txheem rho tawm ntawm Lycium barbarum polysaccharides los ntawm ultrasonic-pab dej leaching tau raug kawm los ntawm kev sim nres-cross, thiab Cov txheej txheem zoo tau txiav txim siab, xws li: ntawm 50 degree, cov khoom siv-dej piv ntawm 1:60, soaking rau 2.5 teev, ultrasonic extraction rau 5 feeb, lub siab tshaj plaws extraction tus nqi ntawm polysaccharides yog 50.36%.

Parameter:

Qhov zoo

1) Tsis xav tau qhov kub thiab txias. Ultrasonic intensified extraction ntawm 40 degree -50 degree dej kub F, ultrasound tuaj yeem txhawb cov nroj tsuag

2) Atmospheric extraction, kev nyab xeeb zoo, kev ua haujlwm yooj yim thiab kev saib xyuas yooj yim.

3) High extraction efficiency. Qhov zoo tshaj plaws extraction tus nqi yuav tau tom qab 20-40 feeb ntawm ultrasonic enhanced extraction, yeej

4) Nws muaj broad spectrum. Kev siv tau yog dav, thiab feem ntau ntawm ntau yam khoom ntawm Suav cov khoom siv tshuaj tuaj yeem muab rho tawm los ntawm ultrasonic.

5) Ultrasonic extraction muaj me ntsis kev sib raug zoo nrog cov khoom ntawm cov kuab tshuaj thiab lub hom phiaj extract. Yog li ntawd, muaj ntau ntau hom extraction kuab tshuaj xaiv los ntawm thiab ntau hom phiaj extracts.

6) Txo kev siv hluav taws xob. Vim tias ultrasonic extraction tsis xav tau cua sov lossis cua sov kub tsawg, lub sijhawm rho tawm yog luv, yog li kev siv hluav taws xob txo qis heev.

7) Lub peev xwm ua tiav ntawm cov khoom siv tshuaj yog loj, ob npaug los yog ob peb zaug siab dua, thiab muaj ob peb impurities, thiab cov khoom xyaw zoo yog yooj yim cais thiab purify.

8) Cov txheej txheem rho tawm muaj tus nqi qis thiab cov txiaj ntsig kev lag luam tseem ceeb.
