Effects of Solvent Type and their Purity on the Yields of Total Phenolic, Total Flavonoids and Antioxidant Activity in Extracts of Longan and Lotkon Peels | Chapter 8 | Current Perspectives in Agriculture and Food Science Vol. 4

 Lotkon and longan are common plants with crops that are rich in nutrients. The pulp is ultimate commonly swallowed component of both products. The potential of additional product components, in the way that the peel and the seed, as warehouses of significant bioactive wealthes has not yet existed adequately examined.The objectives concerning this study was to scrutinize how three types of financially sound (ethanol, methanol, and acetone) touched the yield of total phenolic content (TPC), total flavonoids content (TFC) and DPPH radical scavenging activity of extracts from lotkon and longan peels. Using the process to make softer process, antioxidant and bioactive chemicals were gleaned from fruit samples. For this process, 10 ml of solvent (1:10 w/v) was used to universal containers containing 1 gm of peel powder. The total phenolic content was deliberate using a reduced Folin-Ciocalteu method. The results presented that the 50% methanol extracts for longan peel presented the highest levels of TPC, TFC, and DPPH free radical scavenging endeavors. The TPC varied for two together peel extracts (longan and lotkon) from 343.39±0.22j to 425.55±0.19a, 121.63±0.29j to 321.54±0.12a mg GAE/100g dry weight;TFC from 48.24±0.09j to 86.24±0.11a , 6.47±0.37g to 15.37±0.11a mg QE/100g dry pressure and DPPH radical scavenging activity from 30.79±0.03j to 60.01±0.02a %,25.84±0.01j to 54.76±0.03a % individually. Total phenolic content extraction yields from lotkon and longan peels were considerably (p<0.05) affected by financially sound type and their purity.The judgments demonstrated that longan peel extract had considerably more total phenolic content than lotkon peel extract.  All of the available solvent were used to evaluate the extracts of longan and lotkon peels, 50% flammable liquid was shown expected the most active at extracting total phenolic, total flavonoid and antioxidant project (DPPH). The results of this study supply a useful guide to future goals for the food manufacturing in identifying best choice conditions for deriving antioxidants and desirable phenolic compounds from lotkon and longan peels, as well as a powerful basis for supplementary research in the future.
