Lotkon and longan are favorite plants with crops that are rich in nutrients. The pulp is ultimate commonly swallowed component of both crops. The potential of additional crop components, in the way that the peel and the seed, as warehouses of significant bioactive stuffs has not yet happened adequately examined.The objectives concerning this study was to scrutinize how three types of stable (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 derived 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 planned using a changed Folin-Ciocalteu method. The results revealed that the 50% methanol extracts for longan peel presented the highest levels of TPC, TFC, and DPPH free radical scavenging actions. 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 firm type and their purity.The verdicts 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% intoxicating was shown expected the most productive at extracting total phenolic, total flavonoid and antioxidant endeavor (DPPH). The results of this study determine a useful plan for the food manufacturing in identifying high-quality conditions for deriving antioxidants and desirable phenolic compounds from lotkon and longan peels, as well as a forceful basis for supplementary research in the future.
