Synthesis, characterization and biological activity of 2-Aryl -2, 3-dihydro-1H-perimidine
A series of new 2-Aryl-2,3-dihydro-1H-perimidine, derivatives (3a - j) were synthesized under reflux and at room temperature by condensation reaction of 1,8-diaminonaphthalene (2) with various substituted benzaldehyde using glacial acetic acid a catalyst. The synthesized compounds were characterized by spectroscopic methods, infrared (IR), proton nuclear magnetic resonance (1H-NMR), carbon nuclear magnetic resonance...

Instrumental and chemical characterization of Moringa oleifera Lam root starch as an industrial biomaterial
Moringa oleifera Lam. (Moringaceae family) is a deciduous plant with tuber-like root at the earlier stage. Starch was isolated from the young tuber of the plant and examined instrumentally for its functional groups, X-ray diffractometer (XRD) profile, elemental analysis and antioxidant activities. The Fourier transform infrared spectroscopy analysis shows that peaks at 3465.23 to 3577.11 cm−1 represent...
