Estudio de composición química y posibles usos del pericarpio de Renealmia alpinia

Abstract

Abstract: The indigenous communities of the Ecuadorian Amazon have great wild botanical potential, which is why there is a need to publicize the importance of these resources with industrial applicability through laboratory analysis. In this context, the present work focuses on one of these species: Renealmia alpinia, a herbaceous plant of the family Zingiberaceae, whose red-black pericarp in a state of maturation confers the capacity dyeing and beneficial for health due to its anthocyanin content. The methodology used to characterize the bioactive components was preparative TLC, HPLC-MAS-DAD, quantification by differential pH and NMR, however, the latter due to the unavailability of suitable solvents according to the literature did not turn out to be a feasible method. Regarding the results, through the aforementioned techniques, three metabolites and it was determined that the pericarp has a total amount of anthocyanins of 0.862mg/100g, being mainly constituted by cyanidin-3-o-glucose, cyanidin-3-o-galactose, delphinidin-3-o-glucose and delphinidin-3-o-galactose. Therefore, depending on characterization, the prototype of three products was proposed: an exfoliating serum, bags of tea, and powder capsules with anthocyanins.
