Waxaan baarnay xasilloonida jireed ee kala firdhinta curcumin-ka amorphous iyo doorka isdhexgalka intermolecular curcumin-polymer ee dib u dhigista crystallization.Curcumin waa qaab-dhismeed xiiso leh maadaama ay ka sameysan tahay isku-xidhka hydrogen intra iyo intermolecular labadaba ee crystal.Qayb qaabdhismeed ahaan kala duwan oo polymers-ka kala firdhiyey amorphous ayaa la baadhay;poly (vinylpyrrolidone), Eudragit E100, carboxymethyl cellulose acetate butyrate, hydroxypropyl methyl cellulose (HPMC) iyo HPMC-acetate succinate.Mid-infrared spectroscopy ayaa loo isticmaalay si loo go'aamiyo loona qiyaaso xadka isdhexgalka curcumin-polymer.Xasilooni jireed oo hoos yimaada xaalado deegaan oo kala duwan ayaa lagu kormeeray kala-duwanaanta raajada budada.Xasiloonida kiimikada Curcumin waxaa kormeeray UV-Vis spectroscopy.Go'doominta curcumin amorphous deggan waxay ahayd mid adag maqnaanshaha polymers.Polymers waxay caddeeyeen inay yihiin kuwa wax ku ool ah curcumin crystallization inhibitors oo awood u siinaya soo saarista kala firidhsan adag amorphous;si kastaba ha ahaatee, polymers-yadu waxay muujiyeen awoodo aad u kala duwan si ay u joojiyaan crystallization inta lagu jiro kaydinta muddada-dheer.Curcumin intramolecular hydrogen bonding waxay hoos u dhigtay xadka isku xidhka hydrogen ee polymers;Sidaa darteed polymers-yada intooda badani ma aysan ahayn kuwa wax-ka-qabashada crystallization inhibitors.Guud ahaan, polymers waxay caddeeyeen inay yihiin xannibaadayaasha crystallization, laakiin xannibaadda ayaa xaddidnayd sababtoo ah isku-xidhka hydrogen intramolecular ee curcumin, taas oo horseedaysa hoos u dhaca awoodda polymers si ay ula falgalaan heerka molecular.
