ABSTRACT
Tecoma gaudichaudi DC (Family Bignoniaceae) is a small tree of height 9-12m. and various Tecoma species are attractive to bees, butterflies or birds. Present study focuses on determination of some quantitative microscopical factors of leaves of Tecoma gaudichaudi DC includes Stomatal no., vein islet no etc. Under physicochemical standards various parameters were checked, such as ash value, acid insoluble ash value and moisture content etc. It helps in to check purity of crude drug. Ultimately it helps in evaluation of crude drug and valuable addition of pharmacognostic data towards updating of monograph of plant species.
ABSTRACT
The drug 5 fluorouracil is sparingly soluble in water. The aqueous solubility and dissolution rate of 5-fluorouracil can be increased by inclusion complexation with β-cyclodextrin. Molecular-modeling studies support the formation of stable molecular inclusion complexation of 5-fluorouracil with β-cyclodextrin monomer (1:1). Complexes were prepared by physical mixture, kneading, co evaporation and freeze drying methods. Two ratios 1:1 and 1:2 were formulated. These eight complexes were subjected to Phase-solubility study, molecular modeling and dissolution study. The complexes formed were confirmed by DSC studies. Phase solubility profile indicated that the solubility of 5-fluorouracil increased in the presence of β-cyclodextrin monomer. Results obtained by different characterization techniques clearly indicate that the freeze-drying method leads to formation of solid state complexes between 5-fluorouracil and β-cyclodextrin. The complexation of 5-fluorouracil with β- cyclodextrin lends an ample credence for better therapeutic efficacy.
ABSTRACT
The aim of the study is to investigate the hepatoprotective activity of Melia azedarach L leaves extracts against simvastatin induced hepatotoxicity. The phytochemical screening was carried on the leaves extracts of Melia azedarach revealed the presence of some active ingredients such as Alkaloids, Tannins, Sponginess, Phenols, glycosides, steroids, terpenoids and flavonoids. Leaves of Melia azedarach was successively extracted with ethanol against simvastatin (20mg/kg.p.o) induced hepatotoxicity using Standard drug Silymarin (25 mg/kg). There was a significant changes in biochemical parameters (increases in serum glutamate pyruvate transaminase (SGPT), Serum glutamate oxaloacetate transaminase (SGOT), alanine phosphatase (ALP),serum bilirubin and decrease the total proteins content.) in simvastatin treated rats, which were restored towards normalization in Melia azedarach (300 mg/kg and 500 mg/kg) treated animals. Thus the present study ascertains that the leaf extract of Melia azedarach possesses significant hepatoprotective activity.
