| Abstract: | Based on the reversed-phase high-performance liquid chromatography (RP-HPLC) and electrospray ionization mass spectrometry, a HPLC/ MS method was developed to permit the rapid qualitative analyses of azadirachtin and related triterpenoids from seeds extracted with methanol. APCI standard scanning mass spectra of the ten Neem triteipenoids were recorded. It was discussed that the mass characteristic of ten neem tetranortriterpenoids gained through LC/MS with an ESI interface.Nine-tetranortriterpenoid structures were identified namely asazadirachtin A (1), azadirachtinD (2), azadirachtin (B) (3), salannolactame-21(4), 21-oxo-ochinolide(5), 6-desacetylnimbin(6), nimbin(7), salannol (8) ,salannin (9) |
