“…In turn, other authors described reduced content of essential oil in raw material from lemon balm [59], clary sage [60], and Greek oregano [61,62] fertilized with nitrogen. Furthermore, different effects of nitrogen fertilization on the synthesis of flavonoids were demonstrated depending on the plant species: A positive impact on spearmint [63], no visible impact on yarrow [64], and a negative effect on artichoke [65], and Greek oregano [62]. As reported by Mijani et al [66], plants fertilized with nitrogen at a rate of 75 kg N•ha −1 contained the largest amounts of essential oil, which declined after applying higher nitrogen rates.…”

Yield and Chemical Composition of Raw Material from Meadow Arnica (Arnica chamissonis Less.) Depending on Soil Conditions and Nitrogen Fertilization

Considering the global tendency towards using valuable secondary metabolites of plant origin, there is a need to optimize the cultivation of herbal plants, e.g., the meadow arnica (A. chamissonis Less.). The inflorescences of this species (Arnicae anthodium) have a similar chemical composition and pharmacological activity to that in the mountain arnica (Arnica montana L.), and can be cultivated more easily than the mountain arnica. Therefore this study assesses soil and fertilization effects on the flower head yield and concentrations of active substances (sesquiterpene lactones, flavonoids, and essential oil) with great importance for application in the pharmaceutical and cosmetic industries. A field experiment was carried out during 2017–2019 on two types of soil (sandy and loamy soils) differing in the pH values, organic matter content, and the P, K, and Mg levels. Five levels of nitrogen fertilization were applied in both soil variants: 0, 30, 60, 90, and 120 kg N∙ha−1. The study showed that both the soil type and the nitrogen fertilization had a positive impact on the raw material yield and the content and yield of the main active substances. The cultivation of arnica in the loamy soil was more favorable—it provided a higher flower head yield, higher levels of sesquiterpene lactones, flavonoids, and essential oils, and consequently, a higher yield of these metabolites. High flower head yields were achieved at doses of 60 and 90 kg N∙ha−1. The content of sesquiterpene lactones and essential oils increased in the consecutive study years along with the increase in nitrogen doses. The highest content of flavonoids was detected in flower heads obtained from three-year-old plants fertilized with 60 kg N∙ha−1. High yields of sesquiterpene lactones and essential oils were obtained at doses of 90–120 kg N∙ha−1, whereas the fertilization with 60–90 N∙ha−1 ensured a high yield of flavonoids. The yields of sesquiterpene lactones and essential oil did not depend on their concentration but correlated with the increase in the yield of flower heads of plants cultivated in both sandy and loamy soil variants. In turn, the yield of flavonoids was influenced by both their concentration and the flower head yield. The flower head yield, the content of sesquiterpene lactones, flavonoids, and essential oils, and the yields of metabolites presented in this study indicate favorable climatic conditions for the cultivation of A. chamissonis in Central and Eastern Poland. This proves that a wide range of pharmacologically active substances can be produced in this region of Europe.

“…Monoterpenoids have been considered as the main active and characteristic compounds of the essential oil of O. onites ( Table ). Since they have excellent activity potentials, phytochemical studies have focused particularly on these compounds . In the majority of studies, carvacrol ( 32 ) (2.04 – 92.66%), thymol ( 89 ) (0.18 – 80.44%), linalool ( 56 ) (0.03 – 50.53%), γ ‐terpinene ( 21 ) (0.01 – 18.80%), α ‐terpinene ( 20 ) (0.10 – 15.46%), terpinen‐4‐ol ( 85 ) (0.12 – 15.18%), p ‐cymene ( 6 ) (0.61 – 13.97), β ‐bisabolene ( 99 ) (0.10 – 18.91%), α ‐pinene ( 16 ) (0.02 – 10.33%), borneol ( 26 ) (0.08 – 9.00%), myrcene ( 13 ) (0.06 – 6.33%), α ‐thujene ( 23 ) (0.03 – 6.13%), β ‐caryophyllene ( 104 ) (0.01 – 5.56%), β ‐pinene ( 17 ) (0.01 – 5.40%), camphene ( 1 ) (0.01 – 4.63%), α ‐terpineol ( 82 ) (0.10 – 4.59%), caryophyllene oxide ( 128 ) (0.02 – 2.57), terpinolene ( 22 ) (0.05 – 2.17%), limonene ( 12 ) (0.01 – 1.45%), and α ‐phellendrane ( 14 ) (0.01 – 1.09%) %) have been determined as the main compounds.…”

Origanum onites L., known as Turkish oregano, has great traditional, medicinal, preservative, and commercial importance. It is used for the treatment of several kinds of ailments, such as gastrointestinal disorders, diabetes, high cholesterol, leukemia, bronchitis, etc. In this review, traditional use, phytochemistry, and pharmacology of O. onites reported between 1988 and 2014 were discussed. This review was prepared based on literature survey on scientific journals and books from libraries and electronic sources, such as Web of Science, PubMed, Scopus, Google Scholar, etc. All databases were searched up to June 2014. Several different classes of terpenoids, triterpene acids, phenolic acids, hydroquinones, flavonoids, hydrocarbons, sterols, pigments, fatty acids, tocopherols, and inorganic compounds were detected mainly in the aerial parts of this plant. Pharmacological studies revealed that extracts obtained from several solvents and individual compounds exhibited antimicrobial, antiviral, antioxidant, insecticidal, anticancer, hepatoprotective, genotoxic, antidiabetic, cholinesterase inhibitory, anti-inflammatory, analgesic activities, etc. O. onites, in general, exhibited remarkable activity potential in almost all test systems. The results of toxicity studies indicated that O. onites did not show any significant toxicity and mutagenicity on Drosophila and Salmonella. Toxicity of the extracts/essential oils and also individual compounds should be evaluated on mammalian cells to ensure their safety. The bioactivity of individual compounds aside from terpenoids should also be assessed in detail. Additionally, mode of action for the bioactive compounds should be evaluated to understand the complex pharmacological effects of these phytochemicals.
