Abstract
The effect of Triton X-100 (TX-100) on the penetration of benzyladenine (BA) through isolated tomato (Lycopersicon esculentum Mill.) fruit cuticular membranes was studied using finite and infinite dose diffusion and sorption/desorption systems. Finite dose penetration of BA (18 and 160 μM, pH 2 and 6) from donor droplets (3 μL) was characterized by an initial time lag, a maximum rate of penetration, and total penetration. TX-100 (0.1% w/v) increased maximum BA penetration rates 1.5-40-fold (pH 6, 18 and 160 μM) and total penetration 1.5-3-fold (pH 2 and 6, 18 and 160 μM BA). In infinite dose studies, rates of BA penetration (20 μM, pH 6.0) were increased ~2-fold by TX-100. Surfactant effects were greatest when the surfactant was presented to the outer morphological surface of the cuticle (both native and dewaxed) regardless of whether TX-100 was penetrating in the same or opposite direction to BA. Sorption/desorption of BA was not affected by TX-100.
