Abstract : This work aims to purify the novel β–glucosidase enzyme from shoot of Tabebuia argentea. The enzyme extracted
by using acetate buffer pH 5.5 from the fresh sample. The fractionation using for preliminary purification by ammonium
sulfate ((NH4)2SO4) salt precipitation in the different salt concentration (0-30%, 30-60%, and >60%). The enzyme activity was
measured under basic codition by using hydrolysis reaction of glycosidic bond by using p-nitrophenyl-D-glucopyranoside
(pNPG) as an enzyme substrate. The λmax of corresponding p-nitrophenolate product under basic condition was detected at 405
nm. The enzyme activity via pNPG hydrolysis of seeds extract responds toward around 10-fold over the other part extracts of
Tabebuia argentea, follow by selected enzyme fraction of shoot extract to subject to further chromatographic purification and
enzymatic properties test before apply to be a biocatalyst in biological process.
