Cov txheej txheem extraction raw khoom feem ntau suav nrog cov organic hnyav extraction, alkali extraction, thiab enzyme extraction. Cov txheej txheem tshiab xws li microwave-pab extraction, CO2 supercritical extraction, thiab ultrasound assisted extraction kuj tau siv. Lub hom phiaj tseem ceeb ntawm kev ua kom huv yog cais cov cis thiab trans isomers ntawm resveratrol thiab resveratrol extract los ntawm crude resveratrol, thiaj li yuav tau trans resveratrol. Cov kev siv purification feem ntau muaj xws li chromatography, silica gel kem chromatography, nyias txheej chromatography, high-performance kua chromatography, thiab lwm yam.
