Potent In Vitro α-Glucosidase and β-Secretase Inhibition of Amyrin-Type Triterpenoid Isolated from Datura metel Linnaeus (Angel's Trumpet) Fruits.

ABSTRACT: This study deals with α-glucosidase and β-secretase inhibitory screening of extract/fractions and isolated daturaolone (1), namely, 3-oxo-6-β-hydroxy-β-amyrin (daturaolone) from chloroform fraction of Datura metel L. Among entire fractions, the chloroform soluble fraction showed excellent activity against α-glucosidase with % inhibition 90.8 with IC₅₀160.2 ± 1.85 μg and daturaolone (1) with 98.7% inhibition with IC₅₀840.4 ± 1.74 μM, respectively. Similarly, extract and daturaolone (1) also exhibited significant activity against the β-secretase enzyme (BACE1) with % activities 88.27 and 95.19 and with IC₅₀ values 304.21 ± 2.98 μg and 260.70 ± 1.87 μM, respective
