“…The ABTS •+ radical reducing ability results of the C. vulgare extracts are in agreement with the findings of Malejko et al, in which they determined 3.23 times higher ABTS activity in the refluxed methanolic extracts than in ethyl acetate for the C. palustre extracts (Table 3) [37]. Zhao et al [38] found that the various parts of seven Cirsium species in Taiwan showed varying degrees of antioxidant activities against free radicals in regards to the 16 methanolic standards, according to the ABTS and DPPH methods.…”

The aim of this study was to investigate the compounds in the hexane extract of Cirsium vulgare (Savi.) Ten. and to determine the antibacterial, antifungal, and antioxidant activities of different extracts. The Cirsium vulgare (NGBB 7229) plant was collected from Turkey’s Trakya region. Crude extracts were obtained using different solvents. The chemical composition of Cirsium vulgare was determined in hexane extract using gas chromatography mass spectrometry. The antioxidant activities of the extracts were evaluated by Trolox equivalent antioxidant activity (TEAC), ferric-reducing antioxidant power (FRAP), cupric-reducing antioxidant capacity (CUPRAC), the β-carotene bleaching method, and the determination of superoxide anion scavenging activities. The antibacterial activity was tested against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, and Salmonella typhimurium, whereas the antifungal activity was tested against Candida albicans, Candida glabrata, Candida parapsilosis, Candida krusei, Penicillium chrysogenum, and Aspergillus fumigatus by applying microdilution methods. A total of 41 bioactive compounds were identified using the GC–MS library. Terpenoids were found to be dominant (52.89%), and lup-20(29)-en-3-yl-acetate and lupeol were the most abundant terpenoids. The highest total flavonoid content (25.73 mg catechin/g) and antioxidant capacity were found in the methanolic extract. The highest antibacterial activity was detected against Bacillus subtilis in the ethyl acetate extract, and the highest antifungal activity was found against Candida krusei and Aspergillus fumigatus in the hexane extract. The observed antioxidant characteristics of the C. vulgare extracts could be attributed to the presence of flavonoids. The high antifungal activity of the hexane extract against all fungal strains can be attributed to its constituents, i.e., terpenoids. This study discloses the potential antioxidant and antimicrobial activities, including some bioactive components, of Cirsium vulgare and implies that Cirsium vulgare holds possible applications in the food and pharmaceutical industries as an antioxidant, antibacterial, and antifungal agent.

“…It has been reported that flavonoglignan (including silibinin, silychristin, and silydianin) and flavonoid (such as taxifolin) are major phytochemical compounds in Cirsium plants [11,15]. To further investigate these compounds, the chromatographic separation of a mixture of compounds (silibinin A and B, silychristin, silydianin, and taxifolin) was conducted using the HPLC-PDA system.…”

Cirsium japonicum DC. var. australe Kitam. has been used as an herbal remedy and often involves using the whole plant or roots. However, the bioactivities of different parts of the plant have been far less explored. This study aimed to evaluate the antioxidative ability of methanol extracts from the flowers, leaves, stems, and roots of the Cirsium plant and their possible active components against juglone-induced oxidative stress in the nematode Caenorhabditis elegans. The results showed that the highest dry weight (12.3 g per plant) was observed in leaves, which was followed by stems (8.0 g). The methanol extract yields from the flowers, leaves, and roots were all similar (13.0–13.8%), while the yield from stems was the lowest (8.6%). The analysis of the silymarin contents in the extracts indicated that the flowers, leaves, stems, and roots contained silychristin and taxifolin; however, silydianin was only found in the leaves, stems, and roots. The flower, leaf, and stem extracts, at a concentration of 10 mg/L, significantly reduced juglone-induced oxidative stress in C. elegans, which was potentially due to the presence of silychristin and taxifolin. Overall, C. japonicum DC. var. australe Kitam. contains a significant amount of silymarin and exhibits in vivo antioxidative activity, suggesting that the prospects for the plant in terms of health supplements or as a source of silymarin are promising.

In this study, the anatomical structures of the leaf, stem, root and phyllary of Cirsium caucasicum (Adams) Petr. were clarified. The plant material was collected from Şavşat-Ardahan (Türkiye). The cross and surface sections were cut by hand with a razor blade into microscopic preparation form. The Sartur solution was used in microscopic examinations. According to the results, the leaf is dorsiventral and the epidermal layers contain stomata on both surfaces. In the midrib, besides the main vein, lateral veins are also observed. The upper epidermal layer of the leaf lamina is furnished with setae. The leaf surface is various in terms of cover hairs. The glandular hairs appear on both surfaces of the leaf. The flowering stem is grooved-circular. The non-glandular hairs, glandular hairs and stomata were observed on the epidermis layer of the stem. The vascular bundles are embedded in the pith cells and protected like a cap by pericyclic sclerenchymatous tissue. The root consists of periderm, sclerenchymatous pericycle, secretory canals and vascular tissues. The pith region is composed of completely lignified cells. The secretory canals are arranged regularly in the periphery the root. The cells in the outer and inner epidermis layers of the phyllary are lignified and the secretory canal is located under the sclerenchyma at the outward protrusion, it is accompanied by the vascular bundle.
