MUNOZ JAUREGUI, Ana María, RAMOS-ESCUDERO, Fernando, ALVARADO-ORTIZ URETA, Carlos et al. Evaluación de compuestos con actividad biológica en cáscara de camu camu (Myrciaria dubia), guinda (Prunus serotina), tomate de árbol (Cyphomandra betacea) y carambola (Averrhoa carambola L.) cultivadas en Perú. Rev. Soc. Quím. Perú, oct./dic. 2009, vol.75, no.4, p.431-438. ISSN 1810-634X.

The objective of the present study was to evaluate the extracts of the peel of carambola, tomato tree, guinda, and camu camu for their content of compounds with biological activity, to determine the total polyphenols content, antioxidant activity using the 1,1-difenil-2-picrilhidrasil (DPPH) radical, and free radical scavenging capacity using the ABTS/ABAP system. The samples reported significant statistical difference (p <0,05) for their total polyphenols content and antioxidant activity (IC₅₀ values) according to the standardized Tukey's test. The studied samples appear to be a good source of antioxidants, especially phenolic compounds, whose use might be appropriate in the formulation of functional foods.
