Abstract Liquid–liquidextraction of metal ions using some 1,2,4-triazole Schiff base derivatives as new extractants was studied. Fe 2+ , Zn 2+ , Cu 2+ , Co 2+ , Cd 2+ and Pb 2+ were extracted from the aqueous phase into the organic phase and the extractability for each metal ion was determined by atomic absorption. Interestingly, a competitive extraction was also investigated and then examined at
A series of novel betulinic acid (BA) derivativescontaining 1,2,4-triazole- derived schiff base have been designed and synthesized as α-glucosidase inhibitors. All the title compounds showed higher α-glucosidase inhibitory activity than acarbose and BA, with compound showing the highest α-glucosidase inhibitory activity (IC = 1.52±0.16 μM). Lineweaver-Burk plot analysis suggested that compound was
