“…Several differences were observed in the quantitative pattern of phenolic acids as compared with already published data. [ 15 25 26 27 ] In our study, the amounts of chlorogenic and p -coumaric acids were generally higher than those reported by Craciunescu et al ., 2012 (0.329 mg/g chlorogenic acid; 0.038 mg/g p -coumaric acid). [ 29 ] On the other hand, chlorogenic acid was up to 3 orders of magnitude lower than that established by Albert et al ., 2009 (4.4–6.7 mg/g)[ 12 ] and Pljevljakušić, 2012 (1.9–6.57 mg/g).…”

Introduction:Arnica montana flowers have a long history as herbal medicines for external use on injuries and rheumatic complaints.Objective:To investigate Arnicae flos of cultivated accessions from Bulgaria, Poland, Germany, Finland, and Pharmacy store for phenolic derivatives and sesquiterpene lactones (STLs).Materials and Methods:Samples of Arnica from nine origins were prepared by ultrasound-assisted extraction with 80% methanol for phenolic compounds analysis. Subsequent reverse-phase high-performance liquid chromatography (HPLC) separation of the analytes was performed using gradient elution and ultraviolet detection at 280 and 310 nm (phenolic acids), and 360 nm (flavonoids). Total STLs were determined in chloroform extracts by solid-phase extraction-HPLC at 225 nm. The HPLC generated chromatographic data were analyzed using principal component analysis (PCA) and hierarchical clustering (HC).Results:The highest total amount of phenolic acids was found in the sample from Botanical Garden at Joensuu University, Finland (2.36 mg/g dw). Astragalin, isoquercitrin, and isorhamnetin 3-glucoside were the main flavonol glycosides being present up to 3.37 mg/g (astragalin). Three well-defined clusters were distinguished by PCA and HC. Cluster C1 comprised of the German and Finnish accessions characterized by the highest content of flavonols. Cluster C2 included the Bulgarian and Polish samples presenting a low content of flavonoids. Cluster C3 consisted only of one sample from a pharmacy store.Conclusion:A validated HPLC method for simultaneous determination of phenolic acids, flavonoid glycosides, and aglycones in A. montana flowers was developed. The PCA loading plot showed that quercetin, kaempferol, and isorhamnetin can be used to distinguish different Arnica accessions.SUMMARY A principal component analysis (PCA) on 13 phenolic compounds and total amount of sesquiterpene lactones in Arnicae flos collection tended to cluster the studied 9 accessions into three main groups. The profiles obtained demonstrated that the samples from Germany and Finland are characterized by greater amounts of phenolic derivatives than the Bulgarian and Polish ones. The PCA loading plot showed that quercetin, kaemferol and isorhamnetin can be used to distinguish different arnica accessions.

“…Arnica flos (latin), Fleur d ‘Arnica’ (Fr) , Flor de árnica (Sp) , Arnikablüten (Ge) and Fiore de Arnica (It), and the trade names for the dried roots are Arnikawurzel (Ge), Arnicae radix (latin), Raiz de Arnica (Sp) and Racine d ‘Arnique’ (Fr). However, this species is considered endangered in different European countries like Bosnia‐Herzegovina, Croatia, Slovenia, Germany and Lithuania, Luxembourg, Sweden, Romania, Balkans, Spain and Hungary, so in order to protect this species, its cultivation is increasing but its harvest is not allowed in most European countries including Italy . The plant grows best at an altitude of 500–2500 m in less fertile meadows and on acidic soils in alpine meadows and peat bogs healthlands.…”

“…The second flowers’ diameter varies between 4.9 and 5.7 cm. The flowers appear in July and August with 1–7 flower heads . The best harvesting time for the flowers including the calyx in the Northern Hemisphere is June–August; however, in central Otago, New Zealand, it is December–January and for the roots, it is in spring (April) and autumn (October).…”

Objectives Arnica montana is a widely used therapeutic plant used traditionally to treat various ailments. The objective of this study was to evaluate the botany, phytochemistry and ethnopharmacology along with special emphasis given on pharmacological activity of plant A. montana. Key findings The plant extracts have been reported to possess antibacterial, antitumor, antioxidant, anti-inflammatory, antifungal and immunomodulatory activity. A wide range of chemical compounds including sesquiterpene lactones and their short-chain carbonic acid esters, flavonoids, carotenoids, essential oils, diterpenes, arnidiol, pyrrolizidine alkaloids, coumarins, phenolic acids, lignans and oligosaccharides, etc., are found in different parts of the plant. Summary It has been scrutinized that extensive research has been carried out to explore the therapeutic potential of flowers of the plant. Therefore, investigations should be carried out to explore the therapeutic potential of other parts of the plant for better therapeutic utilization.

“…Many species are widely used and requested by the market and they can be supplied both by wild collections as well as cultivation. In a previous paper we considered the dried flower heads of eight wild Arnica montana L. populations collected in Trentino (Italy) as starting material for the morpho-quantitative and qualitative characterization of different North Italian wild accessions [1][2][3]. In the present evaluation of Italian A. montana, we completed the study of such populations with the sampling of six further populations and investigated in depth their chemical content.…”

The flower heads of fourteen wild Arnica montana L. populations were collected in the summer of 2010 in the provinces of Trento, Brescia and Bergamo (Italy). The dried flowers were analyzed to assess their chemical diversity. HLPC-MS analysis led to the identification of phenolic derivatives and sesquiterpene lactones in the samples, confirming literature data. Quali-quantitative analysis of the flower heads showed similar qualitative patterns both for the phenolic as well as sesquiterpene lactone derivatives, while significant variability was obtained in the amounts (HPLC-DAD) of sesquiterpene lactones (0.45–2.31%), phenolic acids (1.44–2.88%) and flavonoids (0.96–2.44%). The highest quantities of sesquiterpene lactones, flavonoids and phenolic acids were found in Malga Fregasoga (1703 m above sea level), Rifugio Camini (1608 m a.s.l.) and Malga Sass (1817 m a.s.l.) samples, respectively.
