Antioxidant Potential of Some Asteraceae Bercht. &amp; J. Presl. Representatives

This study aimed to evaluate the parameters of antioxidant activity of different parts of Silphium spp. during budding and flowering periods. The four species of Silphium L. genus from the experimental collection of the Cultural Flora Department of M.M. Gryshko National Botanical Garden of the NAS of Ukraine were prepared and used in this research. Total polyphenol content was from 12.32 (S. asperrimum, stems at the budding) to 95.21 (S. laciniatum, leaves at the flowering stage) mg GAE.g -1 DW depending on the organ and stage of vegetation. The total content of phenolic acids in ethanol extracts of investigated plants was from 3.52 (S. asperrimum, buds at the budding) to 34.58 (S. laciniatum, leaves at the flowering) mg CAE.g -1 DW. The total flavonoid content in investigated extracts was from 3.67 (S. perfoliatum, stems at the budding) to 57.31 (S. laciniatum, leaves at the budding) mg QE.g -1 DW. Antioxidant activity was determined by two assays namely the DPPH method and molybdenum-reducing power of extracts and was from 3.33 (S. trifoliatum, stems at the budding) to 9.11 (S. laciniatum, flowers at flowering) mg TE.g -1 and from 29.11 (S. trifoliatum, stems at the budding) to 185.22 (S. laciniatum, leaves at the flowering) mg TE.g -1 DW, respectively. It was found a very strong correlation between total polyphenol compounds, flavonoids, phenolic acids, and molybdenum reducing power r = 0.715-0.905. A weak or moderate correlation was found between DPPH scavenging activity and investigated phenolic compounds (r = 0.110-0.522). Obtained data can be useful for further deep biochemical investigation of plant raw of Silphium spp. and in livestock nutrition branch.

“…& J. Presl family includes 33 species and originated from Northern America (Clevinger and Panero, 2000;Peni et al, 2020). Representatives from this plant family are well-known as medicinal plants with different biological activities such as antioxidant (Shymanska et al, 2020), antifungal, and immunosuppressive (Wolski and Kędzia, 2018).…”

A Comparative Study of Silphium spp. Antioxidant Activity

Vergun

2023

“…(Vergun et al, 2023). Plants from Asteraceae species are characterized by high antioxidant activity of various plant parts (Shymanska et al, 2020). Most investigations with Echinacea species, as well-known representatives of Asteraceae, including antioxidant activity, are connected with E. angustifolia and E. purpurea (Pellati et al, 2004;Jukić et al, 2015).…”

Accumulation of Total Content of Polyphenol Compounds and Antioxidant Activity of Echinacea Moench Species

Vergun

2024

Echinacea Moench species (Asteraceae Bercht. & J. Presl) are one of the most known medicinal and ornamental plants with numerous pharmacological activities. The objects of this study were plant raw materials of Echinacea angustifolia DC. (Kherson Oblast, Ukraine) and E. purpurea (L.) Moench (Kherson and Poltava Oblast, Ukraine) was collected at the start of the vegetation, budding, flowering, and seed ripening period in 2021-2022. It was determined The total polyphenol content (TPC) by the Folin-Ciocalteu method, the total flavonoid content (TFC) by the aluminum chloride method, and the total phenolic acid content (TPAC) with Arnova reagent. The antioxidant activity of investigated plant extracts was conducted by the phosphomolybdenum method (molybdenum-reducing power, MRP) and DPPH method (free radical scavenging activity with 2,2-diphenyl-1-picrylhydrazyl radical). The TPC was determined in the amount of 21.15-78.34 mg GAE•g -1 , TFC in the amount of 8.23-47.98 mg QE•g -1 , and TPAC in the amount of 7.34-29.21 mg CAE•g -1 depending on species, stage, and region of growth. The MRP of investigated extracts was in the range of 54.32-161.34 mg TE•g -1 and FRSA in the range of 6.12-9.69 mg TE•g -1 depending on species, stage, and region of growth. The lowest content of TPC, TFC, and TPAC was determined in the extracts of E. angustifolia in all investigated periods. The highest content of the TPC, TFC, and TPAC was detected in the extracts of E. purpurea from the Kherson region of Ukraine. A positive strong correlation was found between investigated parameters in spring growth, budding, and flowering (r = 0.675-0.998). The negative weak correlation was found in the seed ripening period between TFC and MRP (r = -0.079). The obtained results showed that the accumulation of the total polyphenol content and antioxidant activity of ethanol extracts of Echinacea plants depended on species, period, and region of growth. It can be useful for further pharmacological and biochemical investigations.

et al. 2021

The aim of the research is to determine the effect of application of the developed product (extract) called ALGEX r 6 from natural mineral rock alginite in two different watering periods on the formation of root biomass and aboveground plant biomass of a selected group of medicinal plants (Melissa officinalis L., Malva verticillata L. and Ocimum × citriodorum Vis.) and determining the antioxidant activity in dried leaves and whole plants in aqueous and methyl alcohol extracts by DPPH method. The experiment was established in the Botanical Garden at the Slovak University of Agriculture in Nitra throughout 2020. ALGEX r 6 was prepared by a research team at the Slovak University of Agriculture in Nitra in the form of an extract from the natural mineral rock alginite with an application of thermal and chemical treatment. In the experiment, ALGEX r 6 was applied in the form of a watering in two variants with the same concentration of 3 % solution in 2 decilitres of water, but various application in terms of days in the pre-harvest stage of the above-ground plant biomass of 30 individual plants from each species. There are two diametrically opposite trends of ALGEX r 6 application that are manifesting themselves in M. officinalis and M. verticillata by reducing the root and above-ground part biomass compared to the control variant. The percentage proportionality of root/ above-ground part biomass in M. officinalis decreased from 62.48/30.31 % (control), to 45.57/18.85 % (variant 1) and to 36.07/17.27 % (variant 2), as well as in M. verticillata the root/above-ground part biomass decreased from 16.03/13.93 % (control), to 14.97/9.42 % (variant 1) and to 11.61/10.14 % (variant 2). In the species Ocimum × citriodorum Vis. the opposite trend manifested. The application of ALGEX r 6 watering resulted in increasing the antioxidant activity on the tested plant parts, especially in aqueous extracts in M. officinalis (from 19.30/control to 33.61 %/variant 1, 2), also in O. citriodorum (from 26.56/control to 44.16 %/variant 1), while in methyl alcohol extracts, the antioxidant activity showed a slight increase in all tested species.
