Identificación de compuestos de interés en residuos de las especies Musa paradisiaca y Passiflora edulis F. Flavicarpa degener

Abstract

To identify target compounds with biological and/or industrial activities contained in the waste of species Musa paradisiaca (Unripe and Ripe Platain) and Passiflora edulis F. Flavicarpa degener (Passion Fruit) was developed over a period of six (6) weeks of decomposition of these, preliminary chemical analysis, , these included: determination of percent moisture and ash; elemental analysis CHNS; determination of higher heating value and Lower Calorific Value; determination of total phenol content; determination of percent soluble, insoluble and total lignin; preliminary phytochemical analysis; thin layer chromatography (TLC); and determination of antioxidant activity by the method of DPPH. Analyses revealed that the Lower Calorific Value (LCV) for different biomass waste ranged between 15613 J/g to 17428 J/g, these being significantly comparable with those reported in the literature. Therefore, the three wastes of biomass can be used in energy conversion processes. The antioxidant activity by the DPPH method was evaluated, the waste of unripe plantain peel, M. paradisiaca, showed the highest antioxidant potential exhibiting an IC50 of 187,651 µg/mL, which is directly linked to its content of phenols. The waste of unripe plantain peel, M. paradisiaca, has the highest value of C/N (C/N = 28 - week 1), making it suitable for possible use in the production of biogas through a fermentation process. At high total lignin content (16 - 33%), the wastes of specie Musa paradisiaca (ripe plantain), may have applications as a industrial scale and potentially valuable renewable resource for the production of chemicals mainly of aromatic type; as well as their use as copolymers resins and/or adhesives. The wastes from specie Musa paradisiaca, ripe plantain, for its high ash content (15 – 19%) may have application in eco-agriculture for the recovery of degraded soils.
