 the use of functional beverages such as the infusions of Camellia sinensis and Hibiscus sabdariffa, has grown in recent years worldwide thanks to its content in bioactive compounds with a high antioxidant power, attributing various effects among which its lipid-lowering capacity stands out. Objective: the purpose of the study was to evaluate the capacity of two aqueous extracts of C. sinensis and H. sabdariffa in inhibiting the oxidation of LDL obtained from plasma. Material and methods: organic green tea leaves and dehydrated calyces were used to obtain the extracts. The total phenol content was determined by the Folin-Ciocalteu method and the LDL oxidation test as a biological model for the evaluation of the inhibitory capacity of the extracts. Results: inhibition of LDL oxidation by both extracts was observed with statistical difference from the control (p≤0.05), with C. sinensis extracts being the highest activity. Conclusions: the two species provide a high content of fundamental antioxidants for the body, so that regulated and expertly directed intake could certainly contribute to the treatment of hyperlipidemia.
