1.Ho tla hlalosoa mokhoa o mocha oa ho ntlafatsa likhatiso tsa menoana tse patehileng tsa ninhydrin kapa 1,8-diazafluoren-9-one (DFO) pampiring e futhumatsang.Boholo ba libaka tse futhumatsang mocheso tsa pampiri ea mocheso li ba lefifi ha li phekoloa ka tharollo ea DFO kapa ninhydrin petroleum ether (NPB).Phello ena e fokotsa phapang lipakeng tsa menoana e ntlafalitsoeng le bokamorao.Mokhoa o mocha o hlalositsoeng o fokotsa litšila tsena tse lefifi ntle le ho tlosa lera la thermosensitive le likarolo tsa menoana e ntlafalitsoeng, joalo ka ha ho etsahala ka ho hlatsoa acetone.Ka mokhoa o mocha, menoana e tsoetseng pele e hlaha ka mela e bohale le phapang e phahameng.Ho ile ha etsoa liteko tse pharaletseng, tse lebisang ho tharollo e ntlafetseng ea ho sebetsa, e lefisang pampiri ka bonyane ba lik'hemik'hale, e theko e tlaase, 'me e nolofalletsa lipampiri tse ngata ho phekoloa ka nako e khutšoanyane.Tharollo ea ho sebetsa e na le lik'hemik'hale tse fumanehang khoebong, tse sa tsitsang, tse nang le naetrojene 'me li ka sebelisoa joaloka tšebeliso ea tharollo ea NPB ka ho qoelisoa.
2.Pampiri ena e hlalosa thuto ea karabelo pakeng tsa 1, 8-diazafluoren-9-one (DFO) le amino acid L-alanine ka methyl alcohol.Ho ile ha lefshoa thahasello e khethehileng karolong e ka bang teng ea solvent e bonahalang e sebetsa le DFO ho theha hemiketal e leng mofuta o sebetsang.Tsela e ka 'nang ea etsahala e hlahisoa ho latela lintlha tse bokeletsoeng hona joale.Li-intermediate tsa karabelo le lihlahisoa li ile tsa khetholloa ka mekhoa e fapaneng ea spectroscopic e kenyeletsang mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy, le X-ray crystallography.
