Total of 35 phenolics and flavonols were isolated from flowers and leaves of Dasiphora fruticosa Rydb., from branches of Myricaria alopecuroides Schrenk. and from the herb of Sedum hybridum L. The isolated compounds were identified on the basis of spectral data and tested for their anti-oxidative, acetylcholinesterase and pancreatic lipase inhibitory activities.Quercetin glycosides, gallic acid, (-)EGCG and gossypetin-8-O-xylopyranoside tellimagrandin II exhibited strong anti-oxidative activity by the DPPH scavenging method. The acetylcholinesterase inhibitory activity of quercetin glycosides and (-)EGCG was higher than those of other compounds. Whereas, tellimagrandin II, (-)EGCG and gallic acid derivatives exhibited the most potent inhibitory activity against the pancreatic lipase enzyme among the isolated compounds. Only (-)EGCG showed a prominent activity against all assayed experiments. It was concluded that these plants could be studied further for their potential as anti-oxidative, anti-aging and lipid lowering active products.

The profile and amounts were determined for phenolic compounds in the leaves of Dasiphora fruticosa plants growing in natural populations in the south of the Russian Far East. It was found that the phenolic profiles of the plants are similar among all the analyzed populations, but there are differences in the concentrations of the phenolic compounds. Total concentrations of phenolic compounds, flavonols, rhamnetin glycosides, and free quercetin are 12—46% higher in the leaves of plants of three populations from Shikotan Island. The highest total concentration of ellagic compounds (12.6 mg/g) was noted in the population from Primorsky Krai.

Pectin Substances

A comparative study of biochemical parameters of two closely related species of plants Dasiphora fruticosa and Соmarum salesovianum (shrub and subshrub), growing in the Altai Mountains, was carried out for the first time. It is established that plants contain a rich complex of biologically active substances: flavonols, tannins, catechins, carotenoids, saponins, pectin substances. In the leaves and flowers of D. fruticosa, the content of flavonols, tannins, saponins and pectin substances is 1.1–2.5 times higher than that of C. salesovianum. Particularly significant differences in the content of pectin substances and tannins, which are mainly synthesized in the leaves of plants. By contrast, saponins and flavonols accumulate in flowers more,than in leaves. Maximum content of carotenoids identified in the leaves of plants C. salesovianum (up to 70.4 mg%), but the yellow flowers of D. fruticosa contain carotenoids more 3.2 times than the white flowers of S. salesovianum. High antioxidant activity were found in water-ethanol extracts of leaves (up to 0.85 mg/g) and flowers (up to 0.98 mg/g) of D. fruticosa, which may be due to the increased content of phenolic compounds, in particular tannins compared with the S. salesovianum.

When an imbalance between ROS/RNS generation and antioxidants occurs, oxidative damage will spread over all the cell targets (DNA, lipids, proteins).Antioxidants in foods and medicinal plants have attracted interest in recent years.The aim of the present study was to search the antioxidant active compounds or a new plant species through the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging method of the methanol extracts from 23 plant species belonging to 2 botanical families (Compositae, Rosaceae) collected from natural reserves. The antioxidant activity of these plant extracts were compared with standard solution of rutin.From the 51 plant extracts studied, twenty eight gave IC50 values lower than 200µg/ml. The strongest IC50 values were given by the methanol extracts of Chamaerhodos erecta (aerial parts), Dasiphora parvifolia (leaves, flowers), Cotoneaster melanocarpa (stems), Rubus sachalinensis (stems, leaves), Dasiphora fruticosa (flowers, leaves, stems), Cotoneaster melanocarpa (stems), Filipendula palmata (seeds, leaves), Rubus sachalinensis(leaves).Therefore, these plants may have great relevance in the prevention and therapies of diseases in which free radicals are implicated. In further, more detailed studies on the chemical composition of those extracts as well as studies with other models such as in vivo assays will be called for an interest.Acknowledgements We are grateful to prof A.H.Brantner (Laboratory of Pharmacognosy, University of Graz, Austria) for her helpful suggestion.

Dasiphora Fruticosa

Dasiphora fruticosa (basionym Potentilla fruticosa) is a shrub, known in traditional medicine for centuries. Due to the wide range of pharmacological effects, interest and applications of D. fruticosa extracts are continually increasing; however, reports on optimization of extraction conditions are scarce. Herein, a multi-step high-pressure extraction process with increasing polarity solvents was developed to isolate valuable fractions from D. fruticosa leaves. Supercritical CO2 extraction recovered 2.46 g/100 g of lipophilic fraction, rich in polyunsaturated fatty acids. Further, pressurized liquid extractions (PLE) with acetone, ethanol, and water were applied to obtain antioxidant-rich higher polarity extracts. Under optimized PLE conditions, the cumulative polar fraction yield was 29.98 g/100 g. Ethanol fraction showed the highest yield (15.3 g/100 g), TPC values (148.4 mg GAE/g), ABTS•+, and DPPH• scavenging capacity (161.1 and 151.8 mg TE/g, respectively). PLE was more efficient than conventional solid–liquid extraction in terms of extraction time, extract yields, and in vitro antioxidant capacity. Phytochemical characterization of PLE extracts by UPLC-Q-TOF-MS revealed the presence of hyperoside, ellagic acid, among other health beneficial phenolic substances. Τhis study highlights the potential of high-pressure extraction techniques to isolate antioxidant-rich fractions from D. fruticosa leaves with multipurpose applications, including the prevention and treatment of chronic diseases.
