1.Indlela entsha yokuthuthukisa i-ninhydrin noma izigxivizo zeminwe ezifihlekile ezilashwe yi-1,8-diazafluoren-9-one (DFO) ephepheni elishisayo zizochazwa.Iningi lezindawo ezishisayo zephepha elishisayo ziba mnyama lapho ziphathwa nge-DFO noma isixazululo se-ninhydrin petroleum ether (NPB).Lo mphumela unciphisa umehluko phakathi kwezigxivizo zeminwe ezithuthukisiwe nengemuva.Indlela entsha echazwe inciphisa lokhu kungcola okumnyama ngaphandle kokukhipha isendlalelo se-thermosensitive kanye nezingxenye zeminwe ethuthukisiwe, njengoba kwenzeka ngokugeza i-acetone.Ngokusebenzisa indlela entsha, izigxivizo zeminwe ezithuthukisiwe zivela emigqeni ebukhali kanye nokugqama okuphezulu.Ukuhlolwa okubanzi kwenziwa, okuholele esixazululweni sokusebenza esithuthukisiwe, esikhokhisa iphepha ngobuncane bamakhemikhali, ishibhile, futhi senza isamba esikhulu samaphepha selashwe ngesikhathi esifushane.Isixazululo esisebenzayo siqukethe izinhlanganisela eziphilayo ezitholakala kwezohwebo, ezingaguquki, ezine-nitrogenous futhi zingasetshenziswa njengokusetshenziswa kwesisombululo se-NPB ngokucwiliswa.
2.Leli phepha lichaza ucwaningo lokusabela phakathi kwe-1, 8-diazafluoren-9-one (DFO) ne-amino acid L-alanine ku-methyl alcohol.Kwakhokhwa inzalo ethile endimeni engaba khona yesincibilikisi ebonakala isabelana ne-DFO ukuze yakhe i-hemiketal okuwuhlobo olusebenzayo.Indlela yokusabela engase ibe khona ihlongozwa ngokusekelwe kudatha yamanje eqoqiwe.Ukusabela okuphakathi nemikhiqizo kukhonjwe ngezindlela ezihlukahlukene ze-spectroscopic ezihlanganisa i-mass spectrometry (MS), i-nuclear magnetic resonance (NMR) spectroscopy, kanye ne-X-ray crystallography.
