"Objective: Rubus fraxinifolius and R. rosifolius are found growing in\r\nmountainous areas of West Java and potentially act as an antioxidant. The\r\nobjective of this research was to examine the antioxidant activity of Rubus\r\nrosifolius J. Sm. and R. fraxinifolius Poir. leaves. Methods: Dried leaves\r\npowder were extracted using Soxhlet apparatus with n-hexane, ethyl\r\nacetate, and methanol. The extracts were evaporated, and antioxidant activity\r\nwas determined using DPPH free radical scavenger methods as well as\r\nFRAP reduction capability. Total phenolic contents from the extract gave\r\nthe best antioxidant activity was measured by the Folin-Ciocalteu method.\r\nResults: IC50 of DPPH scavenging activity of n-hexane, ethyl acetate and\r\nmethanolic extracts of R. fraxinifolius were >200; 140.97; and 4.48 ppm,\r\nwhile for R. rosifolius were >200; 29.67; and 5.17 ppm, respectively.\r\nPercent FRAP capacity of R. fraxinifolius in 25 ppm were 55.65; 89.47; and\r\n97.65 %, while for R. rosifolius were 73.51; 82.83; and 96.5, respectively.\r\nTotal phenolic content of the methanolic extract of R. fraxinifolius and\r\nR. rosifolius were 39.0 + 26.5 and 80.62+21.6 mg GAE/g extract.\r\nConclusion: Both methanolic extracts showed a significant optimum\r\ntrapping capability of free radicals and the hexane extracts did not show\r\nantioxidant activity. Thus, it may be concluded that the methanolic extracts\r\nof both leaves possess potent antioxidant properties and had high total\r\nphenolic content. This investigation provides promising results to emphasize\r\nthe importance of antioxidant capabilities of both plants."^^ . . . "EManuscript Services"^^ . . . "Journal Young Pharmacists"^^ . . .
