UV-Vis, FTIR and antioxidant study of Persea americana (Avocado) leaf and fruit: A comparison

Description: Avocado (Persea americana Miller), a well-known nutritional tree crop grown in many parts of the world. The present study compares the UV-Vis and Fourier transform infrared spectroscopy (FTIR) spectrum of Avocado leaf and fruit (peel, pulp, and oil) cultivated in Ecuador; and further its antioxidant activity is evaluated against 1,1-diphenyl-2-picrylhydrazyl (DPPH?). The UV-Vis and FTIR study revealed predominant amount of flavonoids. Among the Avocado leaf and fruit studied, the DPPH? free radical scavenging assay for Avocado leaf had the highest antioxidant activity ranging from 84.46 % to 80.12% with values from 32.60-32.73 ?g gallic acid equivalents per mL. It showed that the order of antioxidant activity in Avocado is leaf > peel > oil > pulp. The antioxidant activity had a positive correlation with total flavonoid content and these plant extracts (specially Avocado leaf) are useful for future antioxidant products.
