Siphenye ukuzinza komzimba kwe-amorphous curcumin dispersions kanye nendima yokusebenzelana kwe-curcumin-polymer intermolecular ekubambezelekeni kwecrystallization.I-Curcumin iyinhlanganisela yemodeli ethakazelisayo njengoba yakha kokubili i-intra kanye ne-intermolecular hydrogen bond ku-crystal.Kwaphenywa isethi ehlukene ngokwesakhiwo yamapholymeri okuhlakazeka kwe-amorphous;i-poly(vinylpyrrolidone), i-Eudragit E100, i-carboxymethyl cellulose acetate butyrate, i-hydroxypropyl methyl cellulose (HPMC) kanye ne-HPMC-acetate succinate.I-spectroscopy ye-Mid-infrared yasetshenziselwa ukunquma nokulinganisa izinga lokusebenzisana kwe-curcumin-polymer.Ukuzinza ngokomzimba ngaphansi kwezimo ezihlukene zemvelo kwakuqashwe i-powder X-ray diffraction.Ukuzinza kwamakhemikhali e-Curcumin kwakuqashwe i-UV-Vis spectroscopy.Ukuhlukaniswa kwe-curcumin ye-amorphous ezinzile kwakunzima ngenxa yokungabikho kwama-polymers.Ama-polymers abonakale esebenza ngempumelelo i-curcumin crystallization inhibitors evumela ukukhiqizwa kwe-amorphous dispersions eqinile;noma kunjalo, ama-polymers abonise amakhono ahluke kakhulu okuvimbela i-crystallization ngesikhathi sokugcina isikhathi eside.I-Curcumin intramolecular hydrogen bonding inciphise izinga lokuhlangana kwayo kwe-hydrogen nama-polymers;yingakho ama-polymers amaningi ayengewona ama-crystallization inhibitors asebenza kahle kakhulu.Sekukonke, ama-polymers afakazele ukuthi angama-crystallization inhibitors, kodwa ukuvimbela kwakulinganiselwe ngenxa ye-intramolecular hydrogen bonding ku-curcumin, okuholela ekwehleni kwekhono lama-polymers ukusebenzisana ezingeni lamangqamuzana.
