Diverse letters indicate a statistical difference (p 0.05) among the peel, seed coat, and seed extracts.Therefore, the higher antioxidant values identified inside the avocado peel extract may very well be associated to its larger content of phenolic compounds. The superiority of your avocado peel extracts, in terms of phenolic compounds content material, in comparison to these from pulp and seed has also been reported in other studies [1,26]. In addition, a recent study performed by Figueroa, Borr -Linares, Lozano-S chez and Segura-Carretero [6] reported that the avocado seed coat extract includes a greater content material of flavonoids, which include catechin, when compared with the seed extract. Catechins has been reported to be molecules having a higher antioxidant activity and an effective SET capacity [30]. This could clarify the larger antioxidant value in the avocado seed coat extracts observed inside the FRAP assay. Additionally, it truly is identified that the antioxidant activity of anthocyanins is higher than those of phenolic acids and some flavonoids. For that reason, the greater content material of anthocyanins in avocado peel and seed coat extracts may possibly be associated to its higher antioxidant activity. 3.two. Quantification of your Individual Phenolic Compounds in Avocado Peel, Seed Coat and Seed Extracts by UPLC-ESI-MS/MS Measuring concentrations of total HIV-2 Inhibitor Storage & Stability phenolics, flavonoids and anthocyanins within the avocado peel, seed coat and seed extracts working with UV/Vis spectrophotometry gives a fast chemical index, but chromatographic strategies are essential to establish structure-activity BRD9 Inhibitor Formulation evidences. In that sense, an identification and quantification of phenolic compounds within the avocado peel, seed coat and seed extracts by UPLC-ESI-MS/MS was performed and display in Table 3. For comparison purposes, the identified phenolic compounds had been also grouped by their distinct chemical structures (phenolic acids, flavonoids, and terpenes) and represented either because the person compounds, the sum of every group along with the total content material identified within the peel, seed coat, and seed extracts. These outcomes reassert those obtained by spectrophotometric solutions performed for their chemical characterization, as the avocado peel extracts had a 1.77- and 4.51-fold larger total phenolic compounds content when compared with seed coat and seed extracts, respectively. Concerning the diverse groups of phenolic compounds, no variations had been observed among the phenolic acids content inside the peel and seed coat extracts, possessing both a drastically higher content than that observed for the seed extract. Regarding the total flavonoids, the highest content was observed within the peel extract, whereas no considerable differences were observed in between the seed coat and seed extracts. Lastly, related outcomes have been observed for the terpenes content, together with the highest content within the peel extract, followed by seed coat and seed extracts.Biomolecules 2021, 11,9 ofTable three.
