Webagainst Trypanosoma cruzi was found (LD50 of 131.8 µg/mL). Forty-seven metabolites were detected in the infusion of A. copa including several phenolic acids and flavonoids which were rapidly identified using ultrahigh performance liquid chromatography orbitrap mass spectrometry analysis (UHPLC-Orbitrap-MS) for chemical profiling. WebThe ultra-performance liquid chromatography (UPLC) method, which involves pre-column derivatization of nitrite with 2,3-diaminonaphthalene (DAN) to form 2,3-naphthotriazole (NAT), offers the advantages of easy sample preparation, simple derivatization, stable derivatives, rapid analysis, high sensitivity and specificity and lack of interferences for …
