Acute effects of VOO, TO, and OA on systolic BP. Sprague–Dawley rats received one p.o. dose of vehicle (V), VOO (2 g·kg−1), TO (1 g·kg−1), or OA (1 g·kg−1). Systolic BP (expressed in mm Hg) was measured 2 h after administration (acute treatment). Each value represents mean ± SEM (n = 10). *, P < 0.05 and ***, P < 0.001 vs. vehicle-treated rats (ANOVA).
