摘要

Extracts from medicinal and aromatic plants and their mixtures have significant potential for use in the food industry due to their antimicrobial and nutraceutical properties. Acantholippia hastulata (Griseb.) (rica-rica) and Schinus areira L. (molle), are medicinal and aromatic plants that grow naturally in the Andean regions of South America. Here, extract blends of molle leaf and rica-rica flowers were screened regarding their antiradical action against DPPH• radical. A selected bioactive blend containing extracts from both species was further evaluated for its in vitro antimicrobial and antioxidant activities, as well as its α-glucosidase inhibitory potential. The blend demonstrated synergistic inhibitory effects against Candida sp., Rhodotorula sp., and α-glucosidase, as well as the ●NO radical, but showed antagonistic effects against the O2●− radical. The main phenolic compounds identified in the synergistic blend include quercetin derivatives (42.6%), isoferulic acid (16.5%) and 3-O-caffeoylquinic acid (9.0%). The bioactive blend was then tested as a preservative in reduced-calorie cayote jam. At a concentration of 800 mg/kg, it effectively inhibited the growth of Candida sp. and Rhodotorula sp., demonstrating efficacy comparable to potassium sorbate. Additionally, the blend successfully preserved the jam during storage, preventing microbial damage.
