Background: The high-performance liquid chromatography (HPLC) method was developed to select salidroside in tablet formulation dietary supplements, raw material containing other components. Further, the proposed method was validated for linearity, precision (system precision, method precision, intermediate or inter-day precision), and accuracy, stability in analytical solution, syst em suitability, and ruggedness. The developed method exhibited the best results in terms of the validation above parameters. The other components and additives did not interfere with their determinations. The method was found to be selective, simple, economical, accurate, reproducible, rapid, and reliable for routine estimation purposes of salidroside in golden root dry extract. The goal of this study was to develop the validation method of salidroside in the dietary supplement. Material and Methods: The Rhodiola rosae L. dry extract was supplied Arshin Co.ltd in People’s Republic of China. The standard salidroside was supplied from Sigma Aldrich Co Ltd. We used solvents for HPLC grade (methanol, acetonitrile). Chromatographic conditions: A gradient HPLC (Shimadzu CBM20AD) with serial dual plunger pump; analytical column: Shimadzu GIST С18 150 x 4.6 mm, particle size 5 μm; flow rate: 1 ml/min; column temperature: 400C, detection: UV 275 nm. Chromatographic procedure: 20 μl of the mixed standard preparation and assay (sample) preparation were separately injected into the chromatography, the chromatograms were recorded, and the responses for the major peaks were measured. The run time was approximately 15 minutes. Results The calibration curves for the salidroside were made by plotting the peak area versus the concentration for each analyte using regression analysis. Each calibration curve was obtained using six levels of concentrations in the range of 100-800 µg/mL. The linear correlation coefficient (r2=1) for all calibration curves was higher than 1 for all analytes. The LOD and LOQ for salidroside were golden root dry extract in 8.788 µg/mL and 26.61 µg/mL, respectively. Accuracy and precision were assessed by analyzing five samples independently prepared at low, middle, and high concentrations. The RSD values of repeatability and intermediate precision were below 1.12%, 1.19 and 1.79%. The accuracy remains between 91 to 109%. The resulting accuracy data were satisfactory for the quantitative analysis of salidroside in golden root dry extract. This article presents a simple, accurate, reproducible, and thoroughly validated HPLC-based method for qualitative and quantitative analysis of salidroside, as part of the quality assessment of golden root dry extract.

Introduction: Amenorrhea has still been listed as one of common diseases among women in Mongolia. Some traditional prescription for amenorrhea, used commonly in Mongolian traditional medicine, needs more attention to dig out its scientific proof of therapeutic effect on pathogenesis of some diseases. Therefore, we aimed to research Shimshin-6 traditional prescription to develop a granule formulation for amenorrhea and other female reproductive diseases, and study its qualitative and quantitative characteristics. Material and method: In this study, Shimshin-6 traditional prescription was randomly collected from 5 pharmaceutical manufacturers named as “Х-1, Х-2, Х-3, Х-4 and Х-5”. The collected prescriptions were granulated and optimized by a wet-granulation method. Then, granule spill weight and flow quality were detected in obtained granule formulation. Result: 20 types of granule formulation from Shimshin-6 were obtained by using 8% and 10% of gelatin, 6% and 8% of polyvinylpyrrolidone as a binder in these formulations. As a result, the suitable binder in this formulation was detected 6% of polyvinylpyrrolidone after researching the granule spill weight and flow rate. For the granule formulations of X-1, X-2 and X-5 prescriptions, the polyvinylpyrrolidone was chosen as the suitable binder due to the result from granule spill weight of the formulation. As for the X-3 and X-4 prescriptions, gelatin was the suitable binder in these formulations. After studying the flow quality of newly obtained granule formulations from “Х- 1, Х-2, Х-3, Х-4 and Х-5”, the most suitable binder was polyvinylpyrrolidone. Conclusion Altogether, these results showed that the most suitable binder for granulating Shimshin-6 traditional medicine was 6% of polyvinylpyrrolidone due to the results from granule spill weight and flow rate.

Coating agents are used in medicine to protect tablets from air or moisture, to mask bitter tastes, or to provide special characteristics for drug release, such as enteric release. There are three main coatings: sugar coating , film coating, and enteric-coating. In this review, we discuss the status of the most commonly used pharmaceutical film coating materials and data were obtained from electronic databases such as PubMed, Google Scholar, and other scientific websites. There are various materials for creating a tablet coating, but the most commonly used material is a water soluble polymer which is used for making a water-soluble film coating.

Excipients are important in the composition of drugs and are the most important requirements for maintaining the stability of drug form, dosage, and physicochemical parameters. Excipients act as protective agents, bulking agents and can also be used to improve bioavailability of drugs in some instances Auxiliary substances included in the composition of medicines are classified as natural, animal, synthetic and semisynthetic. Excipients can become inactive due to chemical, microbiological and physiological effects. Commonly used pharmaceutical excipients are fillers, stabilizers, preservatives, flavor and aroma modifiers, binders, disintegrants, lubricants, lubricants, solvents, and coating agents. Excipients can be considered as indispensible component of medicinal products and in most of the formulations they are present in greater proportion with regards to active pharmaceutical ingredient, as it forms the bulk of the formulation it is always necessary to select an excipient which satisfies the ideal properties for a particular excipient. In this review, materials about coating agents widely used in pharmaceutical practice were compiled from electronic databases such as Pubmed, Google Scholar, and other scientific web pages, using keywords such as Drug excipient interaction, Stability in Oral Solid, and Excipient. .

The incorporation of botanical elements such as Inula helenium L., Astragalus mongolicus Bge., Iris tenuifolia Pall., Ribes diacanthum Pall., and Oxytropis pseudoglandulosa Grubov plays a pivotal role in the formulation of immune-enhancing and kidney-protective Mongolian traditional medicines. These herbal constituents bear rich historical significance in traditional remedies. Ensuring the purity of these herbs is a vital stride in the production of efficacious supplements and medications. Thus, meticulous decontamination of microorganisms assumes paramount importance. The selection of an appropriate sterilization method is important for manufacturers. Sterilization methods divide within three main categories: thermal, chemical, and radiation. This spectrum encompasses many techniques, ranging from moist heat and dry heat to gamma irradiation, ethylene oxide, ozone, and UV treatment. This comprehensive review discusses the efficacy of gamma irradiation, dry heat, moist heat, and chemical treatments, presenting a comparative analysis of their merits. Practically, heat sterilization emerges as a simple and cost-efficient choice. The utilization of an autoclave, subjecting powdered spice paprika to temperatures between 108-125°C for 120 seconds, yielded a substantial reduction in microbial load without compromising the integral bioactive compounds. Gamma irradiation, a common practice in the healthcare and pharmaceutical sectors, stands as another choice in the area of sterilization techniques. Beyond sterilization, upholding rigorous standards of sanitation and hygiene remains a key in the preparations of medicinal plants.
