Abstract

Objective: Currently, inhibiting enzymes such as angiotensin-converting enzyme (ACE), α-glucosidase, α-amylase to limit hypertension (hypertension) and diabetes mellitus (DM) is considered a popular trend. Subjects and methods: This study was carried out with the aim of evaluating the enzyme inhibition ability of total extract (TP) and fractionated extract of diethyl ether (EE), chloroform (CF), n-butanol (BU), and water (WA) from Rhinacanthus nasutus leaves at in vitro level. Results: The highest inhibitory effect was in the chloroform fractions of the enzymes ACE, α-amylase, α-glucosidase with IC50 values of 6.81; 280.05; 72.76 μg/ml. Conclusion: Rhinacanthus nasutus leaf extract can be used to support the treatment of hypertension and type 2 diabetes.
