• YiniI-Caffeic Acid ?
I-Caffeic acid iyinhlanganisela ye-phenolic enezici ezibalulekile ze-antioxidant ne-anti-inflammatory, ezitholakala ekudleni okuhlukahlukene nasezitshalweni. Izinzuzo zayo zezempilo ezingaba khona kanye nokusetshenziswa kokudla, izimonyo, kanye nezithasiselo kuyenza ibe isakhi esibalulekile ocwaningweni lwezempilo olunomsoco.
I-Caffeic acid ingakhiqizwa izitshalo noma ihlanganiswe ngamakhemikhali. Kunezindlela ezimbili ezijwayelekile zokukhiqiza i-caffeic acid:
Ukukhipha emithonjeni yemvelo:
I-caffeic acid itholakala ezitshalweni ezihlukahlukene, njengekhofi, ama-apula, nama-artichokes. Indlela ejwayeleke kakhulu yokuthola i-caffeic acid ukuyikhipha kule mithombo yemvelo. Inqubo yokukhipha ihlanganisa ukusebenzisa izincibilikisi ezifana ne-methanol noma i-ethanol ukuze kuhlukaniswe i-caffeic acid kuso sonke isitshalo. Ukukhishwa bese kuhlanzwa ukuze kutholwe i-caffeic acid.
I-Chemical synthesis:
I-Caffeic acid ingabuye yenziwe ngamakhemikhali kusuka ku-phenol noma ama-phenol esikhundleni. I-synthesis ihilela ukusabela kwe-phenol noma ama-phenol esikhundleni nge-carbon monoxide kanye ne-palladium catalyst ukuze kukhiqizwe i-hydroxypropyl ketone intermediate, ephinde isabeleke nge-catalyst yethusi ukukhiqiza i-caffeic acid.
Le ndlela yokuhlanganisa amakhemikhali ingakhiqiza i-caffeic acid ngobuningi futhi ingalungiswa ukuze kwandiswe isivuno nokuhlanzeka komkhiqizo. Nokho, indlela yokukhipha emithonjeni yemvelo ihambisana nemvelo futhi ikhiqiza umkhiqizo wemvelo owengeziwe.
