Ua matou suʻesuʻeina le mautu faʻaletino o faʻasalalauga curcumin amorphous ma le matafaioi a curcumin-polymer intermolecular fegalegaleaiga i le tolopoina o tioata.Curcumin ose fa'ata'ita'iga fa'a'au'au fa'ata'ita'i e pei ona fa'atūina uma i totonu ma intermolecular hydrogen fa'amau i totonu o le tioata.Sa su'esu'eina se seti fa'avasegaina o polymers ta'ape amorphous;poly(vinylpyrrolidone), Eudragit E100, carboxymethyl cellulose acetate butyrate, hydroxypropyl methyl cellulose (HPMC) ma le HPMC-acetate succinate.Sa fa'aogaina le va'aiga o le vaeluagalemu o le infrared e fa'amautu ma fa'atatau le tele o feso'ota'iga curcumin-polymer.O le mautu o le tino i lalo o tulaga eseese o le siosiomaga na mata'ituina e le pa'u X-ray diffraction.Curcumin chemical stability na mata'ituina e le UV-Vis spectroscopy.O le vavaeeseina o le amorphous curcumin mautu sa faigata ona o le leai o ni polymers.O Polymers na fa'amaonia le lelei o le curcumin crystallization inhibitors e mafai ai ona gaosia le fa'asalalau solo amorphous;ae ui i lea, na faʻaalia e le polymers ni tomai eseese e faʻafefe ai le tioata i le taimi umi o le teuina.Curcumin intramolecular hydrogen bonding na faaitiitia le tele o lona hydrogen bonding ma polymers;o le mea lea o le tele o polymers e le'o sili ona aoga le fa'aininisi fa'ama'i.I le aotelega, o polymers na faʻamaonia e avea ma inhibitors crystallization, ae na faʻatapulaʻaina le faʻasaina ona o le faʻaogaina o le hydrogen intramolecular i curcumin, lea e oʻo atu ai i le faʻaitiitia o le gafatia o polymers e fegalegaleai i se tulaga mole.
