Anti-inflammatory and antioxidant activity of Ficus carica Linn. leaves.

Ficus carica Linn. (Moraceae) is commonly known as edible fig. The leaves, roots, fruits and latex of the plant are medicinally used in different diseases. The leaves are claimed to be effective in various inflammatory conditions like painful or swollen piles, insect sting and bites. However, there has been no report on anti-inflammatory and antioxidant activity of F. carica leaves. Therefore the aim of this study was to evaluate the anti-inflammatory and antioxidant activity of F. carica leaves. Our study validated the traditional claim with pharmacological data. Anti-inflammatory and antioxidant activity of the drug could be due to the presence of steroids and flavanoids, respectively, which are reported to be present in the drug. Furthermore, the anti-inflammatory activity of the drug could be due to its free radical scavenging activity. Further work is also required to isolate and characterise the active constituents responsible for the anti-inflammatory activities.

Evaluation of antihepatotoxic potential of Solanum xanthocarpum fruit extract against antitubercular drugs induced hepatopathy in experimental rodents.

OBJECTIVE: To assess the hepatoprotective effect of Solanum xanthocarpum (S. xanthocarpum) fruit extract against antitubercular drug-induced liver toxicity in experimental animals. METHODS: Ethanolic (50%) fruit extract of S. xanthocarpum (100, 200 and 400 mg/kg bw) was administered daily for 35 days in experimental animals. Liver toxicity was induced by combination of three antitubercular drugs [isoniazid (I) 7.5 mg/kg, rifampicin (R) 10 mg/kg and pyrazinamide (P) 35 mg/kg] given orally as suspension for 35 days in rats. The hepatoprotective activity was assessed using various biochemical parameters like aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatise (ALP), total bilirubin (TBL), albumin (ALB), total protein (TP), lactate dehydroginase (LDH), and serum cholesterol (CHL). Meanwhile, in vivo antioxidant activities as lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) were measured in rat liver homogenate. The biochemical observations were supplemented by histopathological examination. RESULTS: The results demonstrated that treatment with S. xanthocarpum significantly (P<0.05-P<0.001) and dose-dependently prevented drug induced increase in serum levels of hepatic enzymes. Furthermore, S. xanthocarpum significantly (up to P<0.001) reduced the LPO in the liver tissue and restored activities of defence antioxidant enzymes GSH, SOD and CAT towards normal levels. Histopathology of the liver tissue showed that S. xanthocarpum attenuated the hepatocellular necrosis and led to reduction in inflammatory cells infiltration. CONCLUSIONS: The results of this study strongly indicate the protective effect of S. xanthocarpum against liver injury which may be attributed to its hepatoprotective activity, and thereby scientifically support its traditional use.

High-performance thin layer chromatographic quantification of bioactive psoralen and daidzein in leaves of Ficus carica L.

This study was undertaken to quantify psoralen and daidzein by high-performance thin layer chromatography (HPTLC). The methanolic extract of 10 mg mL(-1) concentration solution was prepared for HPTLC quantification of psoralen and daidzein. HPTLC aluminium-backed plates coated with 0.2 mm layers of silica gel 60 F(254) were used as the stationary phase. The working standard solution of psoralen and daidzein was applied along with the test sample solution by means of Camag Linomat IV sample applicator. R (f) values of psoralen and daidzein were found to be 0.60 and 0.88, whilst as their percentage values in methanolic extract were found to be 3.02% and 5.64% (w/w), respectively. A simple quantitative estimation method of psoralen and daidzein by HPTLC is reported that can be used for the quality control of marketed preparations containing Ficus carica. However, further study is warranted to isolate and quantify active constituents present in the leaves of F. carica by sophisticated techniques.

Production, characterization, in vitro and ex vivo studies of babchi oil-encapsulated nanostructured solid lipid carriers produced by a hot aqueous titration method.

An aqueous dispersion of solid fat nanoparticles of babchi oil (BOSLN) was prepared by means of the hot water titration method. Surface morphology was determined by HR-TEM which revealed a fairly spherical shape of the formulations. Further they were evaluated for in vitro drug release characteristics and ex vivo skin permeation profile, zeta potential and particle diameter, rheological measures and droplet size distribution. Highest values for steady state flux (Jss), permeability coefficient (Kp) and enhancement ratio (Er) were observed for formulation, BOSLN3 comprised of oil [10% v/v; BO (3.33%), CAT (6.67%)], Tween 80 (9.25% v/v), transcutol-P (28.75% v/v) and distilled water (53% v/v). These results suggest that the studied SLN might be promising vehicles for babchi oil in the management of psoriasis.
