Objective: To study the preliminary and pharmacognostic characteristics of Ziziphus mauritiana Lam., harvested in Côte d’Ivoire. Identify the drug by anatomy and histochemistry. Method: Macroscopic and microscopic study of the fresh and dry drug and determination of physicochemical parameters. Results: Tree, shrub or bush, 16 m long, 5 m or 4 m, Ziziphus mauritiana Lam. Has bending branches with rounded tops. Its fairly cracked bark is gray or brown, then pale red. The oval or sub-orbicular leaves are alternate and petiolate from 4 mm to 5 mm. The limb, dark green in color, is polished on the upper side and whitish and then densely tomentose on the lower side. The anatomo-histological cut of the limb showed a median rib slightly curved on the upper surface and strongly bulging on the lower side and a broader limb. Each epidermis consisted of small, visible cells more or less rectangular, is covered with a cuticle, outer lipoidal covering; impermissive and resistant, giving it a protective role. The cross-section of the stem, revealed...

The inhibitory effect of Juniperus phoenicea leaves extracts on Xanthine Oxidase activity was evaluated spectrophotometrically at 290 nm. Extracts of Juniperus phoenicea showed a potent XO inhibitory activity. To isolate the active compounds, an in-vitro bio-guided fractionation was undertaken by preparative chromatographic techniques. Fractions 2, 3 and 6 of ethyl acetate extract demonstrated substantial XO inhibitory activity (>80% inhibition) at 400 μg/mL. The highest inhibitory effect was obtained for fraction 3 (87.8%). The major constituents amentoflavone (1) and catechin (2) isolated from the fraction 3 were identified by extensive spectroscopic studies including 1D and 2D NMR experiments. These two compounds have no inhibitory effect on xanthine oxidase; it is deduced that the XOI activity of the fraction 3, was due either to a minor bioactive compound or possible synergisms. However, this study showed that the tested plant species are a potential source of natural XO inhibitors that can be developed, upon further investigation, for treatment of gout and other XO-related...

The present research aimed at scrutinizing the role of Mahua Oil (MO) as a suppository base which can enhance the release of drug in the site of administration. Three formulations were designed with erythromycin as the drug utilizing; F1 (MO and Beeswax in the ratio of 3:1), F2 (MO and PEG 6000 in the ratio of 1:1), and F3 (cocoa butter – 100%) as the base material. The suppositories were prepared using pour molding method after suitable calibration of molds. All the formulations were characterized in terms of breaking strength, disintegration time, drug content, in-vitro dissolution, and accelerated stability studies. The MO containing formulations displayed a good breaking strength, optimized disintegration time, and higher drug content as compared to the cocoa butter formulation. The optimized formulation F2 represented the optimized release of 81.35% over the range of 1 h. A little difference in drug content (1.78%), breaking strength (0.2 Kg/cm2), and disintegrating time (0.6 min) was observed in the accelerated stability study. The study concluded that MO has a...

The drug is obtained from the dried fruit of Nyctanthes arbor-tristis of family Oleaceae. It is also called Coral Jasmine, Parijat, and Harsingar, etc. To confirm the veracity of the claim above, the anticonvulsant effect of the ethanolic extract has been evaluated. In this investigation, the rats were pretreated with different dose of Nyctanthes arbor-tristis ethanolic extract (100, 200 mg/kg) for 14th days and then, they were subjected to maximal electroshock-seizures, the dose of 100 and 200 mg/kg significantly reduced the duration of hind limb extension, and both the doses were statistically found to be equipotent. The reference, standard, Phenytoin (30 mg/kg) provided complete protection. Thus, the present study revealed the anticonvulsant effect of Nyctanthes arbor-tristis against maximal electroshock-induced convulsion in the...
