Abstract

Abstract: The sap of Croton lechleri Müll. Arg. (Euphorbiaceae) is well-known in South American traditional medicine. This research investigated its activity against glycation and oxidative stress (glycoxidation) to estimate its usefulness in ROS-related diseases. The activity of the sap on albumin glycation, LDL oxidation and ROS formation was detected. C. lechleri sap inhibited BSA glycation and exhibited a protective effect against LDL oxidation; at the concentration of 0.8 µg/mL, it extended the Lag phase of almost 60%. Furthermore, the sap was studied on cell viability and ROS production in HUVEC showing valuable free-radical scavenging activity. In detail, the sap (1.0 and 10.0 μg/mL) significantly decreased the baseline level and H2 O2 -induced ROS production in HUVEC. This research showed for the first time the ability of C. lechleri sap to decrease the albumin glycation, LDL oxidation and ROS formation in HUVEC, supporting its potential in vascular diseases.
