ABSTRACTZirconolite is a potential inorganic matrix that is currently investigated in France, in the framework of the 1991 radioactive waste management law, with a view to provide durable containment of the trivalent and tetravalent minor actinides like neptunium, curium, americium and small quantities of unrecyclable plutonium separated from other nuclear waste. To confirm the actinide loading capacity of the zirconolite calcium site and to study the physical and chemical stability of this type of ceramic when subjected to alpha self-irradiation, zirconolite ceramic pellets were fabricated with 10 wt% plutonium oxide (isotope 239 or 238). The 55 pellets are dense (> 93.3% of the theoretical density on average) and free of cracks. They are characterized by a grain size of between 10 and 20 micrometers. X-ray diffraction analyses confirmed the presence of the zirconolite 2M crystalline structure.

Ocimum gratissimum L. leaf oil exhibited many pharmacological properties. This study aimed to formulate and evaluate the physical and chemical stability of O.gratissimum leaf oil nanoemulsion. O.gratissimum leaf oil was extracted by hydrodistillation. The major component of the essential oil eugenol, was analyzed by UV-Vis spectrophotometry. Nanoemulsions of O.gratissimum leaf oil were formulated using polysorbate 80, hyaluronic acid, poloxamer 188, and deionized water by phase inversion composition method. The hydrodynamic diameter, polydispersity index, and zeta potential value of O.gratissimum leaf oil nanoemulsion was evaluated by a dynamic light scattering technique. The %remaining of eugenol in the nanoemulsion was analyzed by UV-Vis spectrophotometry. The essential oil extracted from of O. gratissimum leaf oil was a clear, pale yellow color. The %yield of the essential oil was 0.15 ± 0.03% v/w. The size of the nanoemulsion was less than 106 nm. The polydispersity index of the nanoemulsion was ranging from 0.303 - 0.586 and the zeta potential value of the nanoemulsion was closely to zero, depending on the formulation component. O. gratissimum leaf oil at concentrations ranging from 0.002 - 0.012% v/v contained 35 - 41% of eugenol. The size of nanoemulsion was significantly decreased after storage at 4 °C, while significantly increased upon storage at 45 °C. The size of nanoemulsion stored at 30 °C did not significantly change. The %remaining of eugenol in the nanoemulsion was more than 90% after storage at 4 °C and 30 °C for 28 days. The percentage of eugenol remaining in the nanoemulsion stored at 45 °C was more than 85 - 90%, suggesting that the temperature affected the stability of eugenol in the nanoemulsion.

Carum carvi (Caraway) is a member of Apiaceae family which originated in Asia. Due to its economic importance, it is widely cultivated. Caraway is the only annual species, commonly present in arable land, moist meadows and on low lands to mountains. Caraway has different applications in pharmaceutical and food industries. Phytochemical screening of different medicinal plants is helpful in identifying new sources of industrially and therapeutically important compounds. In this study, Caraway obtained from forest surrounding the village Goherman, Lahaul and Spiti, Himachal Pradesh (India) was used. Seed extract of caraway extracted in methanol (MSE) and distilled water (WSE) was used for phytochemical analysis to determine the constituents of caraway seeds. Further, caraway seeds extract was checked for antibacterial activity [Staphylococcus aureus (ATCC 6538), Salmonella typhimurium (NCTC 74), Escherichia coli (ATCC 25922) and Staphylococcus epidermidis (ATCC 12228)], antioxidant activity and acid neutralizing activity. After analysing the results, it can be said that caraway seeds possess many medicinal properties and it can be used in enhancing human health.

Objective: To objective of this work was to perform phytochemical qualitative and quantitative analyzes of the main secondary metabolites in the root of Berberis microphylla.Methods: The extracts of B. microphylla root were tested through phytochemical screening and the quantification of the most important constituents was carried out using spectrophotometric and gravimetric techniques.Results: Phytochemical screening of both extracts showed the presence of alkaloids, flavonoids, glycosides, cardiac glycosides, saponins, terpenes,and tannins, which are pharmacologically important. Quantification of the major phytochemicals groups showed that the ethanolic extract contains 3.9% alkaloids, 0.46% flavonoids, 9.53% tannins, and 3.60% saponins. Similarly, the methanolic extract contains 6.61% alkaloids, 0.41% flavonoids, 7.40% tannins, and 1.43% saponins.Conclusion: This is the first time that the presence of tannins, flavonoids, and saponins in this plant has been reported. The medicinal properties of the root of B. microphylla may exist due to the presence secondary metabolites.

Objective: The objective of present study was the development, characterization and evaluation of poly-herbal ointment and gel formulations of Nerium Indicum Mill, Artocarpus Heterophyllus Lam, Murraya Koenigii Linn, Punica Granatum Linn extract. Plant derived substances and herbal medicines have recently attracted the great interest towards their versatile application. Medicinal plants are the richest source of bioactive compounds used in traditional and modern medicine. The ointment and gel formulation of plant extract has a sound approach, The poly-herbal ointment and gel formulation were evaluated for its physicochemical parameters like color, odour, pH, spreadability, extrudability, consistency, diffusibility, solubility, washability, non-irritancy and stability. Materials and methods: Extract of all four plants has been separated by the soxhlet extraction by 70% ethanol. Poly-herbal ointment and gel formulation has been prepared by mixing the extract of Nerium Indicum Mill, Artocarpus Heterophyllus Lam, Murraya Koenigii Linn, Punica Granatum Linn with carbapol 940 for Gel formulation and PEG 2000 & PEG 600 for ointment formulation. Results and conclusion: Physicochemical evaluation shows that the poly-herbal ointment and gel formulations fulfilled the criteria as herbal formulation and irritancy test also performed to indicate the effectiveness and efficacy of prepared ointment and gel formulations. The poly-herbal ointment and gel formulations were also evaluated for its stability at various temperature conditions which shows no change in the irritancy, spreadability and diffusion study.
