Invasive Solidago canadensis L. as a resource of valuable biological compounds

Abstract

The phytochemical characteristics of alien species have not yet been fully studied. Meanwhile, the reserves of their raw materials in the secondary distribution range are very large and can be used as new sources of functional ingredients for food, nutraceuticals, cosmeceuticals, and medicines. Particular attention is attracted by species which have closely related native plants that are included in the official pharmacopeia. Solidago canadensis L. in Slovakia has already formed powerful thickets, and a similar species Solidago virgaurea L. is used as a medicinal plant. The goal of our study is to examine biologically active compounds from leaves and inflorescences of Solidago canadensis collected in some invasive populations along the Nitra river and Gron river. Leaves and inflorescences of 3 populations have been taken for analysis. In addition, we tested herbal tea was made by a traditional procedure using 2 types of fermentation. The following parameters have been understudying: total dry matter, ash and protein content, total lipid, saccharides, vitamin C content, total carotenoid content, amino acids content, elemental analysis, and antioxidant activity. Mean values and variations of these parameters are given in the article. The results demonstrated that S. canadensis can be a valuable raw material resource for many sectors of the economy with the possibility of its wider application in the future.

Methodological Approach to the Elaboration of the Analytical Procedure of the Antioxidant Activity Determination of the Schisandra chinensis (Turcz) Baill. Extracts

“…According to the literature, DPPH has an absorption maximum at a wavelength of 514-517 nm (Ivanišová et al, 2017;Shelepova al., 2019;Vergun et al, 2019Grygorieva et al, 2020;Hu et al, 2020;Tvrdá et al, 2020). Reducing a colour intensity of a reaction mixture is carried out by various authors at the time range of 4-15 minutes to 1 hour (Sheng et al, 2011;Mocan et al, 2014;Hu et al, 2020).…”

Possibility of Using an Invasive Species Adenocaulon Adhaerescens Maxim. (Asteraceae) as a Medicin Plant

“…(Krishnaiah et al, 2011). Антиоксидантная активность спиртовых экстрактов из молодых листьев и соцветий A. adhaerescens оказалась на уровне аналогичных показателей, зафиксированных у воздушно-сухих листьев Solidago canadensis L. (84 %) (Shelepova et al, 2019) и существенно выше, чем у листьев S. virgaurea L. (64 %) (Demir et al, 2009) и листьев Conyza bonariensis (L.) Cronquist (58 %) (Daur, 2015). Другое исследование группы растений из семейства Астровых показало, что антиоксидантная активность водных экстрактов методом ДФПГ составила от 73,34 (Echinacea purpurea L.) до 92,56 (Calendula officinalis L.) % (Sytar et al, 2018).…”

“…К тому же А. adhaerescens, хотя и близок к A. himalaicum, но все же другой вид. Кроме того, он является инвазионным видом, а ранее проведенный нами скрининг других чужеродных инвазионных растений продемонстрировал очень высокую степень выраженности их антиоксидантных свойств (Shelepova et al, 2019;Vinogradova et al, 2019 a,b).…”

Survey of the Solidago canadensis L. Morphological Traits and Essential Oil Production: Aboveground Biomass Growth and Abundance of the Invasive Goldenrod Appears to Be Reciprocally Enhanced within the Invaded Stands

“…Solidago canadensis concurrently displays several biologically valuable features-its biomass contains proteins, lipids, saccharides, vitamin C, carotenoids, and amino acids, which indicates that it could be a source of valuable products for the bioeconomy [23]. As the major compounds of its essential oil, monoterpenes, such as α-pinene, β-pinene, bornyl acetate, camphene, limonene and thymol, terpene β-elemene, and sesquiterepenes, such as βgurjunene, δ-cadinene, germacrene D, and longifolene, were determined [24][25][26].…”
