Nanocrystalline composite zinc oxide (ZnO) and CdS with Fe doping thin films grown on glass substrate by chemical method. The parameters like temperature of the solution, UV exposure, pH of solution, immersion time, immersion cycles, have been controlled and standardized for nanocrystalline film. The synthesis NPs were analyzed by X-ray diffraction (XRD). Rietveld method shows that Fe-doped composite ZnO/CdS is a single pure phase and wurtzite structure. Samples were analyzed by sophisticated various instrument like XRD, UV- Visible spectrometer, HRTEM, HRSEM and composition was analyzed by EDX attached with HRTEM. The band gap was calculated by absorption spectroscopy and found that absorption was blue-shifted. The electron structure shows that doping changes the crystal structure and transition level create better efficiency and creates octahedral symmetry. The antibacterial studies showed that the 5.0 wt% Fe-doped exhibited maximum antibacterial effect.

Background:The different parts of Alstonia scholaris (AS) viz. leaf, bark root, and latex are used traditionally to treat pain, swelling, stiffness, immune deficiency, malaria, ulcer, and arthritis. The traditional healers in Dhemaji district of Assam prescribe raw AS latex for topical treatment of inflammatory diseases. The unique feature of this study is that the AS latex has been evaluated scientifically for the first time for its anti-inflammatory properties. Objectives: The present investigation evaluates the anti-inflammatory potential of the AS latex in arthritis using in vitro assays. Materials and Methods: Anti-arthritic potential of AS latex was evaluated using in vitro assays of bovine serum albumin (BSA) denaturation, egg albumin denaturation, and human red blood cell (HRBC) membrane stabilization. Results: It was observed that the standard diclofenac sodium and the AS latex showed good anti-arthritic potential. In BSA denaturation method, the latex, and diclofenac sodium showed 71.59% and 85.23% inhibition of proteinase enzyme at 250 µg/mL, respectively. In the egg albumin denaturation method, the latex, and standard showed the maximum percentage of inhibition of protein denaturation of 70.42% and 81.32%, respectively, at 250 µg/mL. In the HRBC membrane stabilization model, the latex produced considerable anti-arthritic potential in a concentration-dependent manner. At 250 µg/ mL in hypotonic solution, latex, and diclofenac sodium showed 68.77% and 72.12% membrane stabilization, respectively. Conclusion: The present investigation proved the antiarthritic activity of AS latex. It may also be used in the management of other inflammatory diseases.

The present study aimed at the formulation of carminative herbal chewable tablets using herbal constituents. Curcuma longa (turmeric), Foeniculum vulgare (fennel), and Curcuma amada (mango ginger) are the most celebrated herbs in Indian system of traditional medicine. In the present research work, oral chewable tablets were prepared by direct compression and wet granulation method incorporating these three herbs. In both the methods, the powder of turmeric, fennel seed, and ginger mango was prepared initially and it was mixed with additives and preservatives. Physicochemical analysis of the individual drugs, pre-formulation studies, and post-formulation standardization was done to evaluate the quality and purity of the conformation. In the pre-formulation study, it was observed that all the parameters checked for the ingredients were within standard range. Thus, the ingredients were processed for preparing tablets following IP. During the evaluation of tablets, it was found that all the prepared batches of tablets were within the standard range of chewable tablet parameters. Thus, considering these values and following the IP, we found that the chewable tablet that was prepared without altering its therapeutic property was satisfactory with general characteristics of tablet, namely, hardness, disintegration time, friability, and weight variation. The formulation was tested for common people with respect to taste; odor and time required for complete chewing and showed that it can be accepted for the present trends of newer drug delivery dosage forms. The present study provides an approach to come up with a modern outlook to traditional folklore formulations without altering its therapeutic property which is highly essential in industrial applications and to meet consumer preferences and demands. Therefore, it is concluded that the developed chewable tablets may be better alternative to the conventional uses of the herbs.
