The results showed that the butterfly pea extract has the refraction index from 1.382+ 0.25 to 1.390+ 0.30, specific gravity from 0.975 + 0.20 to 0.993+ 0.25, maximum wavelength at 572 and 614 nm
Structural and kinetic evidence of aging after
Near complete recovery of activity was obtained at ~200 h after GB and GF inhibition at pH 4.5, whereas less than 10% of the enzyme reactivated at pH 6.5 (~pH of urine). The trend was similar for DMP more enzyme reactivated at the low pH than at neutral. The results were consistent with aging of the OP adduct at neutral pH.
