Two alpha-glucosidase inhibitors were isolated from the flowers of Sesbania grandiflora and named SGF60 and SGF90. The procedure involved extraction with phosphate buffer, precipitation with ammonium sulfate, ion-exchange chromatography on DEAE-cellulose and gel filtration on Superdex-200. These proteins were identified by using tandem mass spectrometry. The results show partial amino acid sequences of SGF60 similar to p27SJ, a protein from Hypericum perforatum found to suppress HIV-1 gene… CONTINUE READING
