“…Species of this genus are promising medicinal plants. It is known antioxidant [1,2], antigenotoxic [3], antiproliferative [4], cytotoxic [5,6,7,8], antimicrobial, antiviral [9], antimutagenic, hypotensive [10], cardioprotective [11], hypolipidemic, hypoglycemic [1], hepatoprotective properties of these plant extracts [12] depending on a complex of biologically active substances in them. Secondary metabolites of the Nitraria L. genus plants are mainly represented by flavonoids and alkaloids, but the most researches are devoted to investigating alkaloids [12].…”

The paper shows composition and content of phenolic compounds in leaves of 4 Nitraria L. species from 58 populations of Russia, Kazakhstan, and Tajikistan studied with high-performance liquid chromatography(HPLC). The investigation has revealed 27 compounds of phenolic nature: the maximum number (18 components) is detected in leaves of N. sibirica Pall. from Kazakhstan (the Karatal river valley), 16-17 components – in plants from three populations of Siberia, the minimum (6 components) – in leaves of N. komaroviiilljin & Lava ex Bobrov. The analysis has identified hyperoside (quercetin O-glycoside), narcissin (isoramnetin O-glycoside), quercetin (flavonol) and luteolin (flavon). The studied plants accumulate a generous quantity of phenolic compounds. Their content reaches 4.64% in leaves of N. sibirica, 3.11% – in N. schoberi L., up to 3.96% – in N. komarovii. The research results allow speaking about the species-specific composition and content of phenolic compounds of N. sibirica, N. schoberi and N. komarovii. The component composition is weaker in extracts of N. komarovii leaves, but there is a higher content of total phenolic compounds compared to N. schoberi plants. N. pamirica L. Vassil sample is close to N. schoberi on multidimensional analysis of the phenolic compound composition and content.

“…The a-glucosidase inhibitory activity assay was performed according to the methods described by previous reports with minor modications. 25,26 The enzyme was incubated with varying concentrations of piceatannol in a 100 mM phosphate buffer (pH 6.8) at 37 C. The substrate reaction mixture contained 0.6 mM pNPG substrate in a 100 mM phosphate buffer (pH 6.8) with and without piceatannol at various concentrations. The enzyme activity assay was conducted following incubation at 37 C for 7 min.…”

“…It is also a rich source of berries that possess an array of beneficial medicinal effects. Thus, N. tangutorum has also been used as an economic resource [ 30 , 33 , 34 ]. Notably, the geographical distribution range of N. tangutorum includes the EAMS fluctuation zone, which includes Kumtag, Hexi corridor, Badain Jaran, and the Tengger desert regions.…”

The influence of Quaternary climate fluctuation on the geographical structure and genetic diversity of species distributed in the regions of the Qinghai–Tibet Plateau (QTP) has been well established. However, the underlying role of the East Asian monsoon system (EAMS) in shaping the genetic structure of the population and the demography of plants located in the arid northwest of China has not been explored. In the present study, Nitraria tangutorum, a drought-tolerant desert shrub that is distributed in the EAMS zone and has substantial ecological and economic value, was profiled to better understand the influence of EAMS evolution on its biogeographical patterns and demographic history. Thus, the phylogeographical structure and historical dynamics of this plant species were elucidated using its five chloroplast DNA (cpDNA) fragments. Hierarchical structure analysis revealed three distinct, divergent lineages: West, East-A, and East-B. The molecular dating was carried out using a Bayesian approach to estimate the time of intraspecies divergence. Notably, the eastern region, which included East-A and East-B lineages, was revealed to be the original center of distribution and was characterized by a high level of genetic diversity, with the intraspecific divergence time dated to be around 2.53 million years ago (Ma). These findings, combined with the data obtained by ecological niche modeling analysis, indicated that the East lineages have undergone population expansion and differentiation, which were closely correlated with the development of the EAMS, especially the East Asian winter monsoon (EAWM). The West lineage appears to have originated from the migration of N. tangutorum across the Hexi corridor at around 1.85 Ma, and subsequent colonization of the western region. These results suggest that the EAWM accelerated the population expansion of N. tangutorum and subsequent intraspecific differentiation. These findings collectively provide new information on the impact of the evolution of the EAMS on intraspecific diversification and population demography of drought-tolerant plant species in northwest China.
