Ua noiʻi mākou i ke kūpaʻa kino o ka hoʻopuehu curcumin amorphous a me ka hana o ka curcumin-polymer intermolecular intermolecular i ka hoʻopaneʻe ʻana i ka crystallization.ʻO ka Curcumin kahi hui hoʻohālike hoihoi ʻoiai ʻo ia ka mea i hana i nā paʻa hydrogen intra a intermolecular i loko o ke aniani.Ua noiʻi ʻia kahi hui like ʻole o nā polymers dispersion amorphous;poly(vinylpyrrolidone), Eudragit E100, carboxymethyl cellulose acetate butyrate, hydroxypropyl methyl cellulose (HPMC) a me HPMC-acetate succinate.Ua hoʻohana ʻia ka spectroscopy mid-infrared e hoʻoholo a helu i ka nui o nā pilina curcumin-polymer.Ua nānā ʻia ke kūpaʻa kino ma lalo o nā kūlana kaiapuni like ʻole e ka pauka X-ray diffraction.Ua nānā ʻia ke kūpaʻa kemika Curcumin e ka spectroscopy UV-Vis.He paʻakikī ka hoʻokaʻawale ʻana o ka curcumin amorphous paʻa i ka nele o nā polymers.Ua hōʻike ʻia nā Polymers i nā mea hoʻopiʻi crystallization curcumin e hiki ai ke hana i nā dispersion paʻa amorphous;akā naʻe, ua hōʻike nā polymers i nā mana like ʻole e kāohi i ka crystallization i ka wā mālama lōʻihi.ʻO ka hoʻopaʻa ʻana o ka hydrogen intramolecular curcumin i hoʻemi i ka nui o kona hoʻopaʻa hydrogen me nā polymers;no laila, ʻaʻole ʻoi aku ka maikaʻi o ka hapa nui o nā polymers i nā mea hoʻopiʻi crystallization.ʻO ka holoʻokoʻa, ua hōʻike ʻia nā polymers i nā mea hoʻopiʻi crystallization, akā ua kaupalena ʻia ka inhibition ma muli o ka hoʻopaʻa ʻana o ka hydrogen intramolecular i curcumin, e alakaʻi ana i ka emi ʻana o ka hiki o nā polymers e launa pū ma kahi pae mole.
