(Rutaceae) have gained traditional therapeutic importance owing to their high essential oil and coumarins content. Marmesin, a furanocoumarin was identified by TLC and isolated by column chromatography and further purified by Preparative TLC. Presently, there is no appropriate TLC based method available for standardization of F. limonia. A simple, sensitive and accurate high performance thin layer chromatographic (HPTLC) method has been developed for the estimation of marmesin in the methanolic extract of stem bark of Feronia limonia. HPTLC was performed on precoated silica gel 60F254 aluminium plates (20 cm × 20 cm) with Chloroform: Methanol (9.5:0.5), as mobile phase. Quantitative evaluation of the plate was performed in the absorption-reflection mode at 338 nm. The calibration curve was linear in the concentration range of 20 – 100 ng spot–1. The method was validated for precision, repeatability and accuracy. The technique has been applied, for the first time, for the estimation of marmesin. The proposed method was found to be robust, precise, and accurate, it therefore holds potential for detection, monitoring and quantification of marmesin in Feronia limonia and its related formulation.展开更多

Phytochemical analysis of the crude extract was performed to detect presence of different kinds of phytoconstituents. The antibacterial activity was investigated against four Gram positive and four Gram negative bacteria by using disc diffusion method. The plant extract showed moderate antibacterial activity against Gram positive bacteria namely Staphylococcus saprophyticus and Staphylococcus pyogenes and all tested Gram negative bacteria namely Escherichia coli, Shigella boydii, Shigella dysentery and Shigella flexneri in dose dependant manner. The results of castor oil-induced diarrhoeal study showed that Feronia limonia extract significantly reduced the severity & frequency of diarrhoea in mice at a higher dose of 500 mg/kg compared with the standard drug loperamide (25 mg/kg). The present study clearly supports the medicinal value of this plant. The overall results indicate the possibility of presence of some active principles in the plant extract possessing antibacterial and antidiarrhoeal actions.展开更多

Therefore, the present study was undertaken to investigate the hepatoprotective activity of extracts of Feronia limonia fruit on albino rat liver, damage induced by single dose of carbon-tetrachloride (1.5 ml/kg, p.o.). The oral administration of extracts (500 mg/kg, p.o.) for 7 days has shown significant hepatoprotective action. There is reduction in the elevated levels of serum enzymes such SGOT, SGPT, ALP and Serum bilirubin and elevation in level of GSH, GPX,GLY and total protein in Feronia limonia protected rats.展开更多

Administration of 150 mg/kg b.w of synergistic ethanolic extracts of Feronia limonia L., Citrullus colocynthis L., and Tribulus terrestris L. effectively reduced these pathological damages caused by paracetamol intoxication. In addition to serum parameters treatment of 150 rng/kg b.w of synergistic ethanolic extract of Feronia limonia L., Citrullus colocynthis L. and Tribulus terrestris L. also promote the body weight in albino rats. Histopathological changes of the liver samples were compared with the normal control. From our results, we may infer that the mode of action of synergistic 90% ethanolic extracts of Feronia limonia L., Citrullus colocynthis L., and Tribulus terrestris L. (150 mg/kg b.w) in affording the in vivo hepatoprotective activity against paracetamol may be due to the cell membrane stabilization, hepatic cell regeneration and activation of antioxidative enzymes such as glutathione reductase, glutathione peroxidase, superoxide dismutase and catalase.展开更多
