The article presents research data on studies of the current state of the species composition of medicinal plants growing in the south of the Far East on the territory of the forest area of FSBEI HP «Primorskaya State Agricultural Academy» in mountain cedar-latitudinal forests. Biological harvest, production harvest is calculated, size of usage is established and period of restoration of medicinal plants is determined. The work shows how much raw materials can be harvested during one-time operation of thickets. Analysis was carried out, which made it possible to determine the main species composition of plants in hazelnut cedar with linden and oak and in different-shellfish cedar with yellow birch, to distinguish from them the types of medicinal plants characteristic of these types of forest. It was established that 18 types of medicinal plants are promising for volumetric harvesting of above-ground and underground organs. The yield of the remaining species is insignificant and is possible only with the observance of the rules for harvesting during the take-away measures to increase their phytomass.

Serratula Coronata

One of the common plants in Siberia and the Far East of Russia, but little studied, is the crowned saw-wort (Serratula coronata L.s.l.) of the aster family (Asteraceae). The value of this plant is determined by its high content of phytoecdysteroids and flavonoids. From the aerial part (leaves, stems) of S. coronata L.s.l., growing in Siberia (Altai Region), by liquid extraction methods (70% ethanol) and preparative column chromatography on silica gel in the gradient elution mode with a mixture of solvents (carbon tetrachloride and ethyl alcohol), 2 flavonoids were isolated: quercetin-4'-O-β-D-glucopyranoside, luteolin-4'-O-β-D-glucopyranoside. Identification of the isolated compounds was carried out by UV-, NMR-13C-, 1H, 13C-HMBC-spectroscopy and electrospray mass spectrometry. The reverse-phase high-performance liquid chromatography (RP-HPLC) method was the first to investigate the qualitative composition and quantitative content of individual flavonoids in S. coronata L.s.l. plants growing in Altai and in the Primorsky region of the Russian Federation. The composition of flavonoid glycosides and the distribution of their aglycones in Siberian and Far Eastern plants differ and this can be considered a chemotaxonomic trait of the species S. coronata L.s.l. The spectrophotometry method was used to determine the sum of flavonoids in the aerial organs of crowned saw-wort growing in Altai and Primorsky region. The content of flavonoids in the leaves of the plant (6.7–8.3%) exceeds their content in the stems (0.5–0.9%). Crowned saw-wort sickle is a potential source of biologically active compounds of this class.

In the Far East of Russia the genus Serratula L. (family Asteraceae) is represented by 2 species - Serratula manshurica Kitag. and Serratula komarovii Iljin, which can be potential sources of biologically active compounds (phytoecdysteroids). For the first time in the aerial part (leaves, stems, inflorescences) of Serratula komarovii 6 flavonoid compounds (luteolin-7-O-β-D-glucuronopyranoside, apigenin-7-O-β-D-glucuronopyranoside, chrysoeriol-7-O-β-D-glucuronopyranoside, quercetin, luteolin, 3-methylquercetin) were identified by liquid extraction (70% ethyl alcohol) and reverse phase liquid chromatography (RP HPLC). The structure of compounds (luteolin-7-O-β-D-glucuronopyranoside, apigenin-7-O-β-D-glucuronopyranoside, chrysoeriol-7-O-β-D-glucuronopyranoside), isolated by preparative column chromatography on silica gel in a gradient elution with a mixture of solvents (carbon tetrachloride and ethyl alcohol) was proved by UV and NMR-1H, -13C, 1H-,13C-HMBC spectroscopy. It was noted that the dominant flavonoid in Serratula komarovii is luteolin-7-O-β-D-glucuronopyranoside (in the leaves – 4.92±0.98% and in the stems – 1.23±0.25%), and in inflorescences – apigenin-7-O-β-D-glucuronopyranoside (1.10±0.22%). The method of differential spectrophotometry was used to determine the sum of flavonoids in the aerial organs of Serratula komarovii which varies from 1.96 to 9.04%. The maximum content of flavonoids was detected in the leaves – 9.04±0.71%, and the minimum in the stems of the plant – 1.96±0.20%. Thus, Serratula komarovii can be a promising and constantly renewable source of not only phytoecdysteroids, but also flavonoids necessary for the pharmaceutical industry.

The paper investigates cross-cultural differences across Russian regions using the methodology of G. Hofstede. First, it discusses the most common approaches in measuring culture and the application of the Hofstede methodology in subnational studies. It identifies the critical issues in measuring culture at the regional level and suggests several strategies to address them. Secondly, the paper introduces subregional data on individualism and uncertainty avoidance using a survey of students across 27 Russian universities. The data allow to establish geographical patterns of individualism in Russia. It is demonstrated that collectivism is most prevalent in the Volga region, while individualism characteristic becomes stronger towards the Far East. The findings are robust to the inclusion of various controls and different specifications of the regression model. Finally, the paper provides a discussion about the potential of applying the sociocultural approach in economics.
