Objective: To establish the decocting and formulation technology of Saifula granules, and establish a reliable TLC identification quality control standard. Methods: Orthogonal test was used to optimize the water extraction process and TLC was used for qualitative identification. Results: To optimize the process parameters of SFL granules, first, the content of total flavonoids and the total extraction rate were taken as the indexes. Through single factor and orthogonal test, the optimal extraction process was determined as follows: extraction time 1 h, solvent multiple 1:10, extract three times. After the process parameters were determined, in order to further explain the chemical composition of SFL extract, 15 compounds in SFL extract were identified by UHPLC-Q-Orbitrap-MS, 13 batches of SFL extracts were prepared, and their fingerprints were analyzed. The results showed that there were 28 common characteristic peaks in the 13 batches of SFL extracts. The similarity evaluation results of fingerprints showed that the similarities of 13 batches of SFL extracts were greater than 0.9. An HPLC-DAD method for the simultaneous determination of gallic acid, corilagin, and ellagic acid was established. The method has good repeatability, stability, and accurate results. Conclusion: The standard can comprehensively reflect the material basis of SFL granules, and the above methods are accurate, easy to operate, stable and feasible, and provide scientific basis and basis for the development, promotion, and clinical application of SFL granules.

Phellodendri Amurensis Cortex (PAC) is a well-known herbal medicine in China with complex components, but the previous research has mostly focused on its alkaloids analysis. For the first time, a simpler and more efficient method was proposed in this paper to simultaneously determine the content of three different kinds of compounds—phenolic acids, alkaloids and limonoids—in PAC. The phenolic acids included 3-O-feruloylquinic acid, 4-O-feruloylquinic acid and syringin. The alkaloids include magnoflorine, phellodendrine, jatrorrhizine, palmatine and berberine, while the limonoids include obaculactone and obacunone. An approach combining multi-wavelength and HPLC-DAD was used in this study due to the great difference in maximum absorption wavelength of the various components. Four wavelengths at 215, 275, 280 and 310 nm, respectively, were chosen for monitoring. It has been indicated through appropriate tests that this approach is of high accuracy, good repeatability and stability and provides a scientific basis for the quality assessment of PAC and associated derivatives. In addition, the chromatographic fingerprints method combined with multivariate statistical analysis chosen in this study was proved to be effective and reasonable for an accurate classification of 33 batches of samples collected from different locations.

Light Side

This article addresses one of the most actively developing types of design activities – light design. The article comprises quotes of the leading Russian and foreign light design specialists published over the previous five years, as well as the authors’ own conclusions. The thoughts quoted in the article are sometimes opposite to each other and reflect the wide spectrum of professional practice. They reflect the initial opinions of analysts and experts which are often diverging. All of the specialists point at the interdisciplinary nature of the new profession, which imposes additional load on a designer overloaded enough already by the scope and speed of the problems being solved nowadays. The discussion of the new profession of light designer initiated on the pages of professional publications is especially important in view of the development of professional standards and standards of design and architectural education, as well as creation of new educational programmes based on various approaches to the subject in technical and humanitarian institutions. The goal of this article is to introduce light design into the field of fully legitimate sections of design culture, to define the authentic scientific basis of the new creative profession, to initiate a foundation for self-determination of the new synthetic area, which materially affects the state of the profession as a whole and the life standards of a wide variety of consumers. In order to reach the set goal, a comparative and analytical method of study was selected, which allows studying the problem to a large extent and from all angles and finding the ways of overcoming the challenges emerging in the area of the new activity.
