1 Kev Taw Qhia
Resveratrol hmoov (3-4'-5-trihydroxystilbene) yog non-flavonoid polyphenolic compound uas nws lub npe tshuaj yog 3,4',5-trihydroxy-1,2-diphenylethylene (3,4 ',5-stilbene), cov mis mos molecular yog C14H12O3, thiab qhov hnyav molecular yog 228.25. Cov khoom ntshiab ntawm resveratrol yog dawb rau lub teeb daj hmoov, tsw tsw, insoluble nyob rau hauv dej, yooj yim soluble nyob rau hauv organic solvents xws li ether, chloroform, methanol, ethanol, acetone, ethyl acetate, melting point 253-255 degree, Sublimation kub 261 degree.
Ntuj resveratrol hmoov muaj ob lub qauv, cis thiab trans. Los ntawm cov tawv nqaij los yog knotweed, nws tsuas yog muaj nyob rau hauv kev hloov pauv hauv qhov xwm txheej. Ob lub qauv tuaj yeem ua ke nrog cov piam thaj los tsim cis thiab trans resveratrol glycosides. Cov cis- thiab trans-resveratrol glycosides tuaj yeem tso resveratrol raws li kev ua ntawm glycosidases hauv plab. Raws li UV teeb irradiation, trans-resveratrol tuaj yeem hloov mus rau cis-isomer.
