Abstract: Total phenolic compounds (TPC) extraction from the seed and total monomeric anthocyanins (TMA) extraction from the skin of "Sabara" jabuticaba were optimized with simplex lattice designs for solvent mixing, and the extraction time was optimized by univariate design. The optimum conditions for the extraction method were ethanol: water (60: 40 v/v) solvent for TPC (seed) and methanol: water: acetic acid (80:20:0.5 v/v/v) solvent for TMA (skin). For both compound groups, the optimum extraction time was 30 min. The TMA yield for the skin of the "Sabara" variety was 1172.16 mg cyanidin-3-glycoside equivalents per 100 g freeze-dried sample, and for TPC in the seed, it was 86.50 mg gallic acid equivalents per 1 g freeze-dried sample. Both optimized extraction protocols proved to be extremely fast, simple, inexpensive and to have excellent extraction performance. The optimized protocols were compared with two other methods described in the literature and they were also applied to study the TMA contents in skin and the TPC contents in seed of five other varieties of jabuticaba, harvested in 2014 and 2015
