Synopsis

Plants such as Eryngium foetidum, Eucharis moorei, Mansoa alliacea, Pourouma cecropiifolia, Salacca zalacca, and Siparuna pauciflora are traditionally used by Kichwa communities to treat various diseases. The integration of ancestral and scientific knowledge represents an alternative strategy for the management of type II diabetes.

In this study, the content of bioactive compounds, antioxidant capacity, enzymatic inhibition, and hemolytic activity on human erythrocytes were determined using UV-Vis spectrophotometry. The results showed high antioxidant capacity, with IC₅₀ values of 3.53 ± 0.74 and 29.34 ± 2.37 µg/mL (ABTS; DPPH) in P. cecropiifolia, and 14.95 ± 0.30 and 61.70 ± 3.43 µg/mL (ABTS; DPPH) in S. zalacca. Regarding α-amylase inhibition, P. cecropiifolia exhibited strong inhibitory capacity, with an IC₅₀ of 21.77 ± 0.75 µg/mL. Likewise, the extracts showed low cytotoxicity, with hemolytic activity below 2 %. These findings position P. cecropiifolia as a promising species for the management of hyperglycemia.
