“…A preparative TLC was performed with the ethanolic extracts of leaves and petals, the fractions obtained were analyzed in UV-visible, giving max 327.041 nm with a shoulder of 269.019 nm for leaves extract and  max of 345.035 nm with a shoulder of 264.695 nm, for the extract of petals. The signals in the spectrum appear between 250 and 370 nm, a typical region of phenolic groups [26], confirming the reducing capacity of both extracts due to the presence of phenolic groups [27], [28].…”

“…Además, participan en los mecanismos de defensa de las plantas contra diferentes factores ambientales. Las antocianinas también son consideradas como flavonoides con alto potencial antioxidante (Condori et al, 2020) El otro grupo de polifenoles en el cacao son los taninos, el cual está representado por las proantocianidinas. Se encuentran contenidas en las semillas de cacao y están presentes como dímeros, trímeros u oligómeros de flavan-3,4-dioles (representan aproximadamente del 58 % al 65 % del total de polifenoles).…”
