Objective:To investigate the possible mechanisms of the decreasing fluid and food consumption following Hibiscus sabdariffa(HS) consumption.Methods:On the 1st day of pregnancy,rats were randomly divided into three groups with six animals per each group.One group was given tap water,one was given with extract at 0.6 g/100 mL while the third group was given with extract at 1.8 g/100 mL as their drinking solution.All groups received normal rat chow and drinking solution ad libitum.Fluid& food intake and weight were measured daily throughout pregnancy and Na~+ concentration in plasma was determined on the 18th day of pregnancy.Results:Results showed decreased fluid and food consumption,decreased weight gain and increased sodium ion concentration in plasma of rats with HS extract compared with the control group.Conclusions: Consumption of aqueous extract of the calyx of HS during pregnancy decreases food consumption and weight gain through mechanisms that may depend on Na~+ in HS content and elevating Na~+ concentration.
