Standardization in Ayurvedic formulations ensures the establishment of standards for the quality and purity of raw materials, quality control during the drug manufacturing process, production of a good quality finished product, storage and distribution to maintain the quality of the final product. It is an essential tool for establishing quality control methods for Ayurvedic drugs. In Ayurveda, standardization has been well defined and documented in the classical and contemporary texts. Still, these have been written with an individualistic intent and not for industrial or commercial purposes.  Careful contemplation of the classical literature of Ayurveda was done, the current guidelines of WHO on standardization of herbal drugs, latest researches on the same via the internet were explored and examined in the purview of the newest standardization procedures.  In this article, an attempt has been made to bring to light the classical references related to standardization, the milestones in this on-going pursuit have been exhibited, with the use of the latest scientific methods being incorporated for a standardized Ayurvedic drug. It can be concluded from the review that standardization in Ayurveda is an on-going process where one needs to be strictly vigilant about the new scientific methods to study the fine chemical procedures and the intermediate compounds formed, but at the same time be aware of the classical. Ayurvedic methods concepts of the procedure. Asava-arista's medicinal characteristics of Ayurvedic classical dosage forms, liquid dosage forms based on self-generated alcohol with faster absorption, long shelf life, and increased market conformity have led to a continuous rise in demand. New fermentation methods and packaging innovations tend to have been embraced by many Ayurvedic processing units. The importance of standardization of such goods is underlined by these advances in manufacturing, distribution and storage. Therefore, it is of concern to examine the latest manufacturing situation and the standardization of the dosage type regarding the procedure and the consistency and effectiveness of the finished product. In addition to the effort to include criteria of consistency and standardization, the study consists of an overview and deliberates on the importance of improvements made to the conventional preparation processes, ingredients and material used in the process and the potential impact on its efficacy.

Abstract Shewhart X and R charts were used to maintain and validate data quality of percent recovery estimates for 8 analytes determined by 4 procedures used routinely in 4 commercial laboratories over a 2-year period. However, because range (R) estimates of uncertainty did not Include lot-to-lot calibration variability, approximately 24% of the lots were "out-of-control." We extracted pooled standard deviations for So (repeatability within lot), SL (calibration variability), and SR (reproducibility), which represents the total variability. Values of So and SL were generally similar In size although there were some substantial differences between analytes and between laboratories for a given analyte. When control limits were based on reproducibility rather than repeatability, only about 6% of the lots were "out-of-control." However, these limits are less convenient to compute at the bench, wlthln-lot precision estimates are still required, and there Is still no Information on data acceptability. Capability estimates from the grand mean ±3 SR were surprisingly consistent for the 8 analytes. These values coupled with data quality objectives suggested the 82-115% range as the specifications for acceptable individual recoveries. A combination of repeatability limits plus modified limits anchored to specifications retains the simplicity of range computations while offering substantial administrative advantages. Examples are given to illustrate these points.

The book presents the path of production development of honey wine, from the times of Kievan Rus to the present. A deep analysis of culture, honey winemaking, one of the best in its time in world practice, shows what heights were achieved, and how more than a century ago this art was lost. There were many different unsubstantiated sentences, primitive literature, in no way restoring the glory of our great ancestors and not meeting modern requirements for making wines in general. In the last century, as in the entire post-Soviet space, and in Ukraine, the use of honey in winemaking was prohibited and there were ao standard documents on its use for this purpose. The author, with the support of the country's government, while fulfilling the task of the Cabinet of Ministers of Ukraine to improve the quality of fruit and berry wines, produced at that time, it was possible to convince the country's leadership of the need to use honey for the preparation of high-quality honey fruit and berry wines. For this purpose, technical conditions TUU 202.13.022-99 were proposed, developed, and approved "Fruit and berry dessert wines with aromatic additives", where, in addition to the use of fruit and berry, spicy, aromatic, and medicinal raw materials, the use of honey was first laid. For the first time according to TUU, a number of honey wines were developed, approved, and mastered in produccion. At international competicions, such wines have received the highest awards, gold medals, and Grand Prix cups. Subsequently, with the participation of the largest scientific centers, GOST (DSTU 6036: 2008) was prepared. Fruit and berry wines, general technical conditions, in which the production of honey wines arc separated into another group. These regulatory documents fully regulate the production, release, and quality control of honey wines in Ukraine. The author offers a broad overview of the basic terrns and designations necessary for the production of high-quality fruit and berry honey wines. Provides and explains the modem requirements for the classification of honey wines, measures on safety, sanitation, and hygiene are seriously discussed, analyzes the main conditions and factors that detennine the quality of the necessary components, and the preparation of honey wines in general. Since honey wines can only be prepared using fruit and berry wines, including grape juices, the book provides the necessary overview in the processing of fruits, berries, grapes, the reception and quality control of raw materials, and the preparation of juices. Very important and inforrnative material is presented in the chapters on the selection and procurement of honey, for the preparation of honey fruit and berry and honey grape wines. Important sections on the impact of wine on the health and culn,re of wine consumption. The most common diseases and disadvantages of honey wines are described. A very informative and impressive list of honey wines, first developed in Ukraine under the guidance of the author, professor, doctor, technical sciences, Laureate of the State Prize of Ukraine in the field of science and technology Litovchentko A.M., in the amount of 48 items, practically from all raw materials available in Ukraine. To facilitate the work on the preparation of high-quality honey wines, 12 additional applications are presented, providing the main technological process of production. The book is of important practical, theoretical, and scientific interest.
