GC/MS chromatograms of the active Moringa leaves extracts. The chromatograms of (a) P/DEE, (b) P/EA, (c) O/DEE, and (d) O/EA extracts were analyzed using a GC (Agilent Technologies 7890A) interfaced with a mass selective detector (MSD, Agilent 7000) equipped with a nonpolar Agilent HP-5ms ((5%-phenyl)-methylpolysiloxane) capillary column. The carrier gas was helium with a linear velocity of 1 ml/min. The injector and detector temperatures were 200 and 250°C, respectively. A volume of 1 µl of each extract was injected. The MS operating parameters were as follows: Ionization potential 70 eV, interface temperature 250°C, and acquisition mass range 50-800 m/z.
