Abstract
The Wnt signaling pathway is reported to be associated with lung cancer progression, metastasis and drug resistance, and thus it is an important therapeutic target for lung cancer. Plants have been shown as reservoirs of multiple potential anticancer agents. In the present investigation, the ethanolic leaf extract of Artemisia vulgaris (AvL-EtOH) was initially analyzed by means of gas chromatography-mass spectrometry (GC–MS) to identify the important phytochemical constituents. The GC–MS analysis of AvL-EtOH exhibited 48 peaks of various secondary metabolites such as terpenoids, flavonoids, carbohydrates, coumarins, amino acids, steroids, proteins, phytosterols, and diterpenes. It was found that the treatment with increasing doses of AvL-EtOH suppressed the proliferation and migration of lung cancer cells. Furthermore, AvL-EtOH induced prominent nuclear alteration along with a reduction in mitochondrial membrane potential and increased ROS (reactive oxygen species) generation in lung cancer cells. Moreover, AvL-EtOH-treated cells exhibited increased apoptosis, demonstrated by the activation of caspase cascade. AvL-EtOH also induced downregulation of Wnt3 and β-catenin expression along with cell cycle protein cyclin D1. Thus, the results of our study elucidated the potential of bioactive components of Artemisia vulgaris in the therapeutic management of lung cancer cells.

Abstract
Four sesquiterpenoids were isolated from an ethyl acetate-soluble fraction of A. princeps ethanolic extract: seco-tanapartholide B (5-epi-seco-tanapartholide A) (1), 4-epi-seco-tanapartholide A (2), 11,13-dehydrodesacetylmatricarin (3) and desacetylmatricarin (4). Compounds 1 - 3 dose-dependently inhibited nitric oxide (NO) production in lipopolysaccharide (LPS)-activated macrophages. These compounds also decreased mRNA and protein expression levels of inducible NO synthase and cyclooxygenase-2 as well as mRNA levels of pro-inflammatory cytokines (interleukin-1β and tumour necrosis factor-α) in LPS-stimulated RAW 264.7 macrophages. Moreover, compound 3 effectively enhanced the expression of heme oxygenase-1 (HO-1) in macrophages in the presence or absence of LPS. Additionally, the exocyclic methylene of α-methylene-γ-lactone moiety of compound 3 was found to be essential for the activation of the NF erythroid 2-related factor 2 (Nrf2)/HO-1 pathway. Here, we firstly report the isolation of compounds 3 and 4 from A. princeps and the anti-inflammatory activity of compound 3 by up-regulation of Nrf2/HO-1 pathway.

Abstract
The Artemisia L. genus includes over five hundred species with great economic and medicinal properties. Our study aimed to provide a comprehensive metabolite and bioactivity profile of Artemisia campestris subsp. lednicensis (Spreng.) Greuter & Raab-Straube collected from north-eastern Romania. Liquid chromatography with tandem high-resolution mass spectrometry (LC-HRMS/MS) analysis of different polarity extracts obtained from the aerial parts led to the identification of twelve flavonoids, three phenolic acids, two sesquiterpene lactones, two fatty acids, one coumarin, and one lignan. The antioxidant and enzyme inhibitory properties were shown in the DPPH (0.71−213.68 mg TE/g) and ABTS (20.57−356.35 mg TE/g) radical scavenging, CUPRAC (38.56−311.21 mg TE/g), FRAP (121.68−202.34 mg TE/g), chelating (12.88−22.25 mg EDTAE/g), phosphomolybdenum (0.92−2.11 mmol TE/g), anti-acetylcholinesterase (0.15−3.64 mg GALAE/g), anti-butyrylcholinesterase (0−3.18 mg GALAE/g), anti-amylase (0.05−0.38 mmol ACAE/g), anti-glucosidase (0.43−2.21 mmol ACAE/g), and anti-tyrosinase (18.62−48.60 mg KAE/g) assays. At 100 μg/mL, Artemisia extracts downregulated the secretion of tumor necrosis factor (TNF)-α in a lipopolysaccharide (LPS)-stimulated human neutrophil model (29.05−53.08% of LPS+ control). Finally, the Artemisia samples showed moderate to weak activity (minimum inhibitory concentration (MIC) > 625 mg/L) against the seventeen tested microbial strains (bacteria, yeasts, and dermatophytes). Overall, our study shows that A. campestris subsp. lednicensis is a promising source of bioactives with putative use as food, pharmaceutical and cosmetic ingredients.

Abstract
Big sagebrush ( Artemisia tridentata) is a common shrub growing in the cold intermountain regions of western North America. The plant is an important food source for herbivores and was used in Native American traditional medicine. In this work, the essential oils were obtained from 3 individuals of A tridentata subsp. tridentata growing in southwestern Idaho. The essential oils were analyzed by gas chromatographic methods including chiral gas chromatography. The major components in the essential oils were yomogi alcohol (5.8%-30.8%), santolina epoxide (1.7%-10.5%), camphor (5.2%-20.1%), and ( Z)-tagetone (0.9%-8.9%). ( + )-α-Pinene, ( + )-β-pinene, ( + )-verbenone, ( − )-( E)-β-caryophyllene, and ( − )-δ-cadinene were the only enantiomers observed for these compounds. Camphene and camphor, on the other hand, showed wide variability in enantiomeric distribution. The enantiomeric distributions in A tridentata subsp. tridentata differ widely compared to other Artemisia species. There are large variations in the chemical compositions in A tridentata, both between subspecies and within subspecies.

Abstract
The Artemisia L. genus comprises over 500 species with important medicinal and economic attributes. Our study aimed at providing a comprehensive metabolite profiling and bioactivity assessment of five Artemisia species collected from northeastern Romania (A. absinthium L., A. annua L., A. austriaca Jacq., A. pontica L. and A. vulgaris L.). Liquid chromatography–tandem high-resolution mass spectrometry (LC-HRMS/MS) analysis of methanol and chloroform extracts obtained from the roots and aerial parts of the plants led to the identification of 15 phenolic acids (mostly hydroxycinnamic acid derivatives), 26 flavonoids (poly-hydroxylated/poly-methoxylated flavone derivatives, present only in the aerial parts), 14 sesquiterpene lactones, 3 coumarins, 1 lignan and 7 fatty acids. Clustered image map (CIM) analysis of the phytochemical profiles revealed that A. annua was similar to A. absinthium and that A. pontica was similar to A. austriaca, whereas A. vulgaris represented a cluster of its own. Correlated with their total phenolic contents, the methanol extracts from both parts of the plants showed the highest antioxidant effects, as assessed by the DPPH and ABTS radical scavenging, CUPRAC, FRAP and total antioxidant capacity methods. Artemisia extracts proved to be promising sources of enzyme inhibitory agents, with the methanol aerial part extracts being the most active samples against acetylcholinesterase and glucosidase. All Artemisia samples displayed good antibacterial effects against Mycobacterium tuberculosis H37Ra, with MIC values of 64–256 mg/L. In conclusion, the investigated Artemisia species proved to be rich sources of bioactives endowed with antioxidant, enzyme inhibitory and anti-mycobacterial properties.

Abstract
Sagebrush (Artemisia spp.) are dominant wild plants in large areas of the U.S., Canada and Mexico, and they include several species and subspecies. The aim was to determine if there are significant differences in essential oil (EO) yield, composition, and biological activity of sagebrush within the Bighorn Mountains, U.S. The EO yield in fresh herbage varied from 0.15 to 1.69% for all species, including 0.25-1.69% in A. tridentata var. vaseyana, 0.64-1.44% in A. tridentata var. tridentata, 1% in A. tridentata var. wyomingensis, 0.8-1.2% in A. longifolia, 0.8-1% in A. cana, and 0.16% in A. ludoviciana. There was significant variability in the EO profile between species, and subspecies. Some EO constituents, such as α-pinene (0-35.5%), camphene (0-21.5%), eucalyptol (0-30.8%), and camphor (0-45.5%), were found in most species and varied with species and subspecies. The antioxidant capacity of the EOs varied between the species and subspecies. None of the sagebrush EOs had significant antimicrobial, antimalarial, antileishmanial activity, or contained podophyllotoxin. Some accessions yielded EO with significant concentrations of compounds including camphor, eucalyptol, cis-thujone, α-pinene, α-necrodol-acetate, fragranol, grandisol, para-cymene, and arthole. Therefore, chemotypes can be selected and possibly introduced into culture and be grown for commercial production of these compounds to meet specific industry needs.

Abstract
The genus Artemisia, often known collectively as "wormwood", has aroused great interest in the scientific community, pharmaceutical and food industries, generating many studies on the most varied aspects of these plants. In this review, the most recent evidence on health effects of edible Artemisia species and some of its constituents are presented and discussed, based on studies published until 2020, available in the Scopus, Web of Sciences and PubMed databases, related to food applications, nutritional and sesquiterpene lactones composition, and their therapeutic effects supported by in vivo and clinical studies. The analysis of more than 300 selected articles highlights the beneficial effect on health and the high clinical relevance of several Artemisia species besides some sesquiterpene lactones constituents and their derivatives. From an integrated perspective, as it includes therapeutic and nutritional properties, without ignoring some adverse effects described in the literature, this review shows the great potential of Artemisia plants and some of their constituents as dietary supplements, functional foods and as the source of new, more efficient, and safe medicines. Despite all the benefits demonstrated, some gaps need to be filled, mainly related to the use of raw Artemisia extracts, such as its standardization and clinical trials on adverse effects and its health care efficacy.

Abstract
BACKGROUND Artemisia weed pollen allergy is important in the northern hemisphere. While over 350 species of this genus have been recorded, there has been no full investigation into whether different species may affect the allergen diagnosis and treatment. This study aimed to evaluate the variations in amino acid sequences and the content of major allergens, and how these affect specific IgE binding capacity in representative Artemisia species. METHODS Six representative Artemisia species from China and Artemisia vulgaris from Europe were used to determine allergen amino acid sequences by transcriptome, gene sequencing and mass spectrometry of the purified allergen component proteins. Sandwich ELISAs were developed and applied for Art v 1, Art v 2 and Art v 3 allergen quantification in different species. Aqueous pollen extracts and purified allergen components were used to assess IgE binding by ELISA and ImmunoCAP with mugwort allergic patient serum pools and individual sera from five areas in China. RESULTS The Art v 1 and Art v 2 homologous allergen sequences in the seven Artemisia species were highly conserved. Art v 3 type allergens in A. annua and A. sieversiana were more divergent compared to A. argyi and A. vulgaris. The allergen content of Art v 1 group in the seven extracts ranged from 3.4% to 7.1%, that of Art v 2 from 1.0% to 3.6%, and Art v 3 from 0.3% to 10.5%. The highest IgE binding potency for most Chinese Artemisia allergy patients was with A. annua pollen extract, followed by A. vulgaris and A. argyi, with A. sieversiana significantly lower. Natural Art v 1-3 isoallergens from different species have almost equivalent IgE binding capacity in Artemisia allergic patients from China. CONCLUSION AND CLINICAL RELEVANCE There was high sequence similarity but different content of the three group allergens from different Artemisia species. Choice of Artemisia annua and A. argyi pollen source for diagnosis and immunotherapy is recommended in China.

Abstract
Several reviews have been published on Artemisia's derived natural products, but it is the first attempt to review the chemistry and pharmacology of more than 80 alkaloids and allied nitrogen compounds obtained from various Artemisia species (covering the literature up to June 2018). The pharmacological potential and unique skeleton types of certain Artemisia's alkaloids provoke the importance of analyzing Artemisia species for bioactive alkaloids and allied nitrogen compounds. Among the various types of bioactive Artemisia's alkaloids, the main classes were the derivatives of rupestine (pyridine-sesquiterpene), lycoctonine (diterpene), pyrrolizidine, purines, polyamine, peptides, indole, piperidine, pyrrolidine, alkamides, and flavoalkaloids. The rupestine derivatives are Artemisia's characteristic alkaloids, whereas the rest are common alkaloids found in the family Asteraceae and chemotaxonomically links the genus Artemisia with the tribes Anthemideae. The most important biological activities of Artemisia's alkaloids are including hepatoprotective, local anesthetic, β-galactosidase, and antiparasitic activities; treatment of angina pectoris, opening blocked arteries, as a sleep-inducing agents and inhibition of HIV viral protease, CYP450, melanin biosynthesis, human carbonic anhydrase, [3H]-AEA metabolism, kinases, and DNA polymerase β1 . Some of the important nitrogen metabolites of Artemisia include pellitorine, zeatin, tryptophan, rupestine, and aconitine analogs, which need to be optimized and commercialized further.

Abstract
Artemisia princeps var. orientalis is a well-known medicinal food, which has been used for the treatment of several diseases including bacterial infection. We examined the antiviral effects of the essential oil from A. princeps var. orientalis and its compounds, borneol, α-thujone and camphor, against murine norovirus-1 (MNV-1) and feline calicivirus-F9 (FCV-F9). The time-of-addition plaque assays were used to determine the ability of essential oil to interfere with viral infection. The maximum activities, following the pretreatment of FCV-F9 and MNV-1, reached 48% inhibition on FCV-F9 and 64% inhibition on MNV-1 at 0.1 and 0.01% of the essential oil, respectively. Neither borneol nor camphor exhibited an antiviral activity, whereas α-thujone, a major compound of the essential oil, showed strong inhibition on FCV-F9 and MNV-1.

Abstract
In this work, LC-ESI-TOF-MS and GC-EI-MS were used to assess the potential of Artemisia herba alba as a source of health-promoting constituents. Besides, the antioxidant, the antimicrobial and the cytotoxic potentials were evaluated. A total of 86 metabolites, including C-glycosylated and methylated flavones, quinic acid derivatives, coumarins, sesquiterpenes lactones, terpenoids, fatty acids, carbohydrates, organic acids and alkaloids were identified, sixty five of them were reported for the first time in A. herba alba. The main compounds were di-O-caffeoylquinic acids, artemisinic acid, menthol, α-ketoglutaric acid, scopolin, isoschaftoside and sucrose. Furthermore, results showed that A. herba alba possess high total antioxidant activity (Total antioxidant activity=423mg gallic acid equivalent/g dry weight), strong potential anticancer capacity against MCF-7 breast cancer and HeLa human cervical cell lines (IC50 of 15 and 70μg/ml, respectively), and moderate antibacterial activity against S. aureus, B. thurigiensis and A. hydrophila. These results support the use of this plant as alternative bioactive ingredient for functional foods, dietary supplements or nutraceuticals.

Abstract
Volatile organic compounds (VOCs) play important roles in the environmental adaptation and fitness of plants. Comparison of the qualitative and quantitative differences in VOCs among closely related taxa and assessing the effects of environment on their emissions are important steps to deducing VOC function and evolutionary importance. Headspace VOCs from five taxa of sagebrush (Artemisia, subgenus Tridentatae) growing in two common gardens were collected and analyzed using GC-MS. Of the 74 total VOCs emitted, only 15 were needed to segregate sagebrush taxa using Random Forest analysis with a low error of 4%. All but one of these 15 VOCs showed qualitative differences among taxa. Ordination of results showed strong clustering that reflects taxonomic classification. Random Forest identified five VOCs that classify based on environment (2% error), which do not overlap with the 15 VOCs that segregated taxa. We show that VOCs can discriminate closely related species and subspecies of Artemisia, which are difficult to define using molecular markers or morphology. Thus, it appears that changes in VOCs either lead the way or follow closely behind speciation in this group. Future research should explore the functions of VOCs, which could provide further insights into the evolution of sagebrushes.

Abstract
An efficient and rapid protocol for the establishment of Artemisia tilesii "hairy" root culture is reported. Leaf explants of aseptically growing plants were cocultured with Agrobacterium rhizogenes A4 wild strain or A. rhizogenes carrying the plasmids with nptII and ifn-α2b genes. Root formation on the explants started in 5-6 days after their cocultivation with bacterial suspension. Prolongation of explant cultivation time on the medium without cefotaxime led to stimulation of root growth. The effects of sucrose concentration as well as of the levels of synthetic indole-3-butyric acid (IBA) and native growth regulator Emistim on the stimulation of A. tilesii "hairy" root growth were studied. Maximum stimulating effect both for the control and for transgenic roots was observed in case of root cultivation on the media supplemented with IBA-up to 7.95- and 9.1-fold biomass increase, respectively. Cultivation on the medium with 10 μl/L Emistime has also led to the control roots growth stimulation (up to 2.75-fold). Emistime at 5 μl/L concentration led to 5.46-fold mass increase in only one "hairy" root line. Higher sucrose content (40 g/L) stimulated growth of two hairy root lines but had no effect on growth of the control roots.

Abstract
We report the sequencing and assembly of three transcriptomes from Big (Artemisia tridentata ssp. wyomingensis and A. tridentata ssp. tridentata) and Low (A. arbuscula ssp. arbuscula) sagebrush. The sequence reads are available in the Sequence Read Archive of NCBI. We demonstrate the utilities of these transcriptomes for gene discovery and phylogenomic analysis. An assembly of 61,883 transcripts followed by transcript identification by the program TRAPID revealed 16 transcripts directly related to terpene synthases, proteins critical to the production of multiple secondary metabolites in sagebrush. A putative terpene synthase was identified in two of our sagebrush samples. Using paralogs with synonymous mutations we reconstructed an evolutionary time line of ancient genome duplications. By applying a constant mutation rate to the data we estimate that these three ancient duplications occurred about 18, 34 and 60 million years ago. These transcriptomes offer a foundation for future studies of sagebrush, including inferences in chemical defense and the identification of species and subspecies of sagebrush for restoration and preservation of the threatened sage-grouse.

Abstract
CONTEXT To date, there are no reports to validate the Indian traditional and folklore claims of Artemisia maderaspatana L. (syn. Grangea maderaspatana L.) (Asteraceae) for the treatment of Alzheimer's disease. OBJECTIVE The present study characterizes the volatile components (non-polar compounds) of A. maderaspatana and evaluates its acetylcholinesterase inhibition potential. MATERIALS AND METHODS The essential oils (yield 0.06% v/w) were obtained from fresh aerial part of A. maderaspatana. The characterization of volatile components (non-polar compounds) was performed by GC-MS data and with those of reference compounds compiled in the spectral library of in-house database. The in vitro acetylcholinesterase (AChE) inhibition of the volatile organic constituents (VOC's) of A. maderaspatana aerial part was evaluated in varying concentration ranges (0.70-44.75 µg/mL) with Ellman's method. RESULTS The major components were α-humulene (46.3%), β-caryophyllene (9.3%), α-copaene (8.2%), β-myrcene (4.3%), Z(E)-α-farnesene (3.7%), and calarene (3.5%). Chemical variability among other Artemisia spp. from different climatic regions of India and countries namely Iran and France was observed. The experimental results showed that diverse volatile organic constituents of A. maderaspatana have significant acetylcholinesterase inhibitory activity (an IC50 value of 31.33 ± 1.03 µg/mL). This is the first report on the inhibition of acetylcholinesterase properties of essential oil of A. maderaspatana obtained from fresh aerial part. CONCLUSIONS The present results indicate that essential oil of A. maderaspatana isolated from the northern region of India could inhibit AChE moderately. Therefore, the possibility of novel AChE inhibitors might exist in VOCs of this plant.

Abstract
Galanthamine is a naturally occurring acetylcholinesterase (AchE) inhibitor that has been well established as a drug for treatment of mild to moderate Alzheimer disease, but the role of the compound in plant metabolism is not known. The current study was designed to investigate whether galanthamine could redirect morphogenesis of Artemisia tridentata Nutt. cultures by altering concentration of endogenous neurosignaling molecules acetylcholine (Ach), auxin (IAA), melatonin (Mel), and serotonin (5HT). Exposure of axenic A. tridentata cultures to 10 µM galanthamine decreased the concentration of endogenous Ach, IAA, MEL, and AchE, and altered plant growth in a manner reminiscent of 2-4D toxicity. Galanthamine itself demonstrated IAA activity in an oat coleotile elongation bioassay, 20 µM galanthamine showed no significant difference compared with 5 μM IAA or 5 μM 1-Naphthaleneacetic acid (NAA). Metabolomic analysis detected between 20,921 to 27,891 compounds in A. tridentata plantlets and showed greater commonality between control and 5 µM treatments. Furthermore, metabolomic analysis putatively identified coumarins scopoletin/isoscopoletin, and scopolin in A. tridentata leaf extracts and these metabolites linearly increased in response to galanthamine treatments. Overall, these data indicate that galanthamine is an allelopathic phytochemical and support the hypothesis that neurologically active compounds in plants help ensure plant survival and adaptation to environmental challenges.
