Fig. 4From: Self-microemulsifying system of an ethanolic extract of Heliopsis longipes root for enhanced solubility and release of affininRelease profile of affinin from HL-SMDS and the ethanolic extract of H. longipes root in two solutions at different pH through time, at a constant temperature of 37 °C and stirring at 50 rpm. Data expressed as mean ± SEM (n = 3), *p < 0.05 vs. HL-SMDS (pH 1), #p < 0.05 HL-SMDS (pH 6.8) vs. H. longipes extract (pH 1 and 6.8)Back to article page
