Exploring antioxidant and α-glucosidase inhibition in L. extracts: a comprehensive phytochemical study.

This study analysed extracts obtained from the leaves of , , and to determine their chemical composition, antioxidative properties, and α-glucosidase inhibitory capacity. By using liquid chromatography with a diode array detector, we identified chlorogenic acids, flavonoids, tannins, proanthocyanidins, saponins, and triterpenes in the extracts. The antioxidant activities of the extracts were found to be directly related to their total phenolic, flavonoid content and enzyme inhibition.

Leishmanicidal, Trypanocidal and Antioxidant Activity of Amyrin-Rich Extracts from Cambess.

Aims: This study aimed to characterize and evaluate leishmanicidal and trypanocidal action as well as cytotoxicity on macrophages and antioxidant ability of extracts, obtained by supercritical CO and ultrasound-assisted extractions of Uvaia () leaves.

Methods: Leaves from were submitted to supercritical CO (E1) and ultrasound-assisted (E2) extractions. The characterization of extracts was done using GC-MS and HPLC.
