Aspectos nutricionales y fisioquímicos de Ilex laurina Kunth (Aquifoliaceae) : un estudio comparativo con Ilex paraguariensis

ABSTRACT: Ilex laurina K., a Colombian plant whose infusion presents antioxidant and antiproliferative properties, belongs to a species of Yerba Mate tea. Objective: Evaluate the nutritional and physiochemical properties of an infusion using Ilex laurina K. leaves as a potential raw material, functional food and substitute for the conventional Ilex paraguariensis tea. Objective: To evaluate the nutritional and physiochemical properties of an infusion using Ilex laurina K. leaves as a potential raw material, functional food and substitute for the conventional Ilex paraguariensis tea. Materials and Methods: Phytochemicals and carbohydrates by HPLC analysis, solubility, mineral measurement using atomic absorption spectrophotometry, and sensorial analysis. Results: The Ilex laurina K. infusión compared with Ilex paraguariensis infusion found higher concentrations of chlorogenic acid (429.2 ± 20.2 versus 47.4 ± 1.9 mg / kg), p-coumaric (47.3 ± 2.4 versus 24.4 ± 0.9 mg / kg), xanthines (1.4-1.8 times), iron, copper, zinc, and the likes of caffeic acid (52.6 ± 18.8 versus 47.4 ± 1.9 mg / L) (p> 0.05). Ferulic acid (21.5 ± 1.6 mg / L) and fructose (0.4 ± 0.003 g / L) were detected, while glucose (0.8 ± 0.007 g / L) and higher concentrations of magnesium and manganese (p<0.05) we found in the Ilex paraguariensis. Ilex laurina K. infusion was accepted by 64% of consumers, regardless of gender; and respective acceptability of the following characteristics: color (51%), smell (47%), flavor (42%) and sweetness (47%). Conclusions: Ilex laurina K. infusion is well accepted by consumers, and contains a higher concentration of phenol compounds, xanthines, iron, copper, zinc and fructose than Ilex paraguariensis infusion, and contributes less glucose, magnesium and manganese. Keywords: Ilex paraguariensis, mate, sensory test, phytochemicals, minerals, macronutrients.
