متن کاملNootropic Activity of Calyces of Hibiscus Sabdariffa Linn
Nootropic acitivity of calyces of Hibiscus sabdariffa Linn. was studied in mice. Elevated plus maze and passive avoidance paradigm were employed to evaluate learning and memory parameters. Scopolamine (0.4 mg/kg, i.p.) was used to induce amnesia in mice. The aqueous extracts of calyces of Hibiscus sabdariffa (HS-100 and 200 mg/kg, p.o.) significantly attenuated amnestic deficits induced by scop...
متن کاملMechanisms of the anti-hypertensive effect of Hibiscus sabdariffa L. calyces.
Previous studies have demonstrated the anti-hypertensive effects of Hibiscus sabdariffa L. (HS) in both humans and experimental animals. To explore the mechanisms of the anti-hypertensive effect of the HS, we examined the effects of a crude methanolic extract of the calyces of HS (HSE) on vascular reactivity in isolated aortas from spontaneously hypertensive rats. HSE relaxed, concentration-dep...
