DIURETIC ACTIVITY OF CAROB (CERATONIA SILIQUA L.) HONEY: COMPARISON WITH FUROSEMIDE
Background: Honey has wide range of biological activities. It has effect on renal function, and urinary nitric oxide and prostaglandins level.
The present study was conducted to evaluate diuretic potential of carob honey, collected from Morocco, in normal rats and the results were
compared with use of furosemide.
Materials and methods: Adult male Wister rats weighing between 230 and 278 g were used. The animals were divided into three groups; group
1 received oral administration of distilled water (10 ml/kg BW), and served as control group, group 2 received oral administration of furosemide
(10 mg/kg BW), and group 3 was treated with oral administration of carob honey (100 mg/kg BW). Urine volume, and urine and plasma sodium
and potassium were measured after single dose of the interventions and after daily administrations of the interventions.
Results: After the single dose of carob honey, urine output was significantly increased at all time intervals (1-6 hrs and at 24 hrs after
administration). The daily dose of carob honey for nine days significantly increased urine volume as compared to control group. Carob honey
increased urinary levels of sodium and potassium, and did not cause hypokalemia, while furosemide increased urinary sodium and potassium
and caused hypokalemia.
Conclusion: Carob honey has diuretic, natriuretic and kaliuretic activity without side effects of hypokalemia that was observed with use of
furosemide
Ceratonia siliqua honeys from Morocco: Physicochemical properties, mineral contents, and antioxidant activities
Physicochemical properties, main mineral content, and antioxidant activity were determined for eight floral carob honeys collected from different geographical regions of Morocco. Moroccan honeys showed good chemical and nutritional qualities, fulfilling the criteria described in the standard codex for honey. The percentages obtained for ashes were (0.13–0.69%), electrical conductivity (0.36–1.35 mS/cm), water content (17.30–22.80%), pH (4.17–5.05), free acidity (11.0–42.50 meq/kg), lactone acidity (4.0–16.50 meq/kg), and for total acidity (16.50–59.50 meq/kg). In addition, minerals such as K, Na, Mg, Cu, Zn, and Ca of honey samples were determined and potassium was the major mineral in all samples. The antioxidant activities based on the free radical scavenging, reducing power, and total antioxidant activity were investigated, and the antioxidant capacity of the honey samples was correlated with their biochemical constituents such as total phenol and flavonoids content, and the best antioxidant capacity was confirmed by the honey from Taounate
Antioxidant, hypoglycemic, and hepatoprotective effect of aqueous and ethyl acetate extract of carob honey in streptozotocin -induced diabetic rats
Aim: The aim of the study included the effect of aqueous extract (AE) and ethyl acetate extract (EAE) on blood sugar in diabetic rats and their effects on liver enzymes and lipid panel in control and diabetic rats. Furthermore, the antioxidant activity of the EAE was studied in vitro and compared with AE.
Materials and Methods: Sugar and antioxidant content of AE and EAE were determined. In vitro antioxidant activity of AE and EAE was estimated by 2, 2-diphenyl-1-picrylhydrazyl and ABTS*+ radical scavenging assay, ferric-reducing antioxidant power assay, and total antioxidant assay. To study the effect of the extracts on blood glucose level (BGL), lipid profile, and liver function in non-diabetic and diabetic rats, five groups of six rats each were treated with distilled water, AE, EAE, glibenclamide (GLB), and sucrose for 8 days. Plasma glucose level (PGL), total cholesterol (TC), triglycerides (TG), transaminases (alanine transaminase [ALT] and aspartate transaminase [AST]), and alkaline phosphatase (ALP) were determined. The effect of the interventions on BGL after acute administration also was investigated. Diabetes was induced by streptozotocin injection.
Results: EAE contains significantly lower content of fructose and glucose than AE (p<0.05), and it has no sucrose. AE and EAE exhibited a significant antioxidant activity and high antioxidant content; the antioxidant content was higher in AE than EAE (p<0.05). In diabetic rats, acute treatment by AE increased PGL, while EAE significantly lowered BGL as compared to the untreated diabetic rats. Both interventions significantly decreased BGL as compared to the sucrose treated group in diabetic rats (p<0.05). EAE was more potent than GLB. Sucrose caused 13% increment in BGL after 8 days of induction of diabetes, while AE caused only 1.3% increment. Daily treatment by EAE decreased significantly AST, ALT, ALP, and TC. EAE decreased significantly TC and TG level in diabetic rats in comparison to the untreated diabetic group.
Conclusion: The study showed for the 1st time that EAE has more hypoglycemic effect than AE, and both extracts prevent the increment in BGL on day 8 after induction of diabetes observed in the control and sucrose treated group. EAE significantly ameliorated the lipid and liver function disorders induced by diabetes
Potential effect of Silybum marianum L. and Cistus ladaniferus L. extracts on urine volume, creatinine clearance and renal function
Objective: To investigate the diuretic and renal effects of Silybum marianum L. and Cistus ladaniferus L. in normal rats. Methods: Four groups of rats were used in each experiment. The first group received water, the second group received Cistus ladaniferus L. extract (100 mg/kg b.wt), the third group received Silybum marianum L. extract (100 mg/kg b.wt), and the fourth group received furosemide (10 mg/kg b.wt). Variables including urine volume, plasma and urine sodium, potassium and creatinine, and creatinine clearance were measured. Two experiments were conducted. A single dose of each intervention was used and the variables were measured during 24 h, and the interventions were given daily for a total of 8 d and the variables were measured during various intervals. Results: The single dose of each plant extract increased urine volume at all-time intervals and increased urine sodium and potassium excretion without affecting plasma sodium and potassium (P<0.05). On the day 8 after daily administration, the plant extracts induced a significant diuresis and natriuresis without affecting serum electrolytes (P<0.05), while furosemide caused hypokalemia. Both plant extracts significantly increased creatinine clearance (P<0.05). Conclusions: Silybum marianum L. and Cistus ladaniferus L. increase creatinine clearance and have a significant diuretic effect without affecting serum electrolytes. Silybum marianum L. is more potent than furosemide or Cistus ladaniferus L
Protective Effect of Morocco Carob Honey Against Lead-Induced Anemia and Hepato-Renal Toxicity
Background/Aims: Natural honey has many biological activities including protective effect against toxic materials. The aim of this study was to evaluate the protective effect of carob honey against lead-induced hepato-renal toxicity and lead-induced anemia in rabbits. Methods: Twenty four male rabbits were allocated into four groups six rabbits each; group 1: control group, received distilled water (0.1 ml / kg.b.wt /daily); group 2: received oral lead acetate (2 g/kg.b.wt/daily); group 3: treated with oral honey (1g /kg.b.wt/daily) and oral lead (2 g/kg.b.wt/daily), and group 4: received oral honey (1 g/kg.b.wt/daily). Honey and lead were given daily during 24 days of experimentation. Laboratory tests and histopathological evaluations of kidneys were done. Results: Oral administration of lead induced hepatic and kidney injury and caused anemia during three weeks of the exposure. Treatment with honey prevented hepato-renal lead toxicity and ameliorated lead-induced anemia when honey was given to animals during lead exposure. Conclusion: It might be concluded that honey has a protective effect against lead-induced blood, hepatic and renal toxic effects
