Artemisiae Argyi Folium, the dried leaves of Artemisia argyi, has been widely used in traditional Chinese and folk medicines for treatment of hemorrhage, pain, and skin itch. Phytochemical studies indicated that volatile oil, organic acid and flavonoids were the main bioactive components in Artemisiae Argyi Folium. Compared to the volatile compounds, the research of nonvolatile compounds in Artemisiae Argyi Folium are limited. In the present study, an accurate and reliable fingerprint approach was developed using HPLC for quality control of Artemisiae Argyi Folium...

Global climate and land use change are altering plant and soil microbial communities worldwide, particularly in arctic and alpine biomes where warming is accelerated. The widespread expansion of woody shrubs into historically herbaceous alpine plant zones is likely to interact with climate to affect soil microbial community structure and function, however our understanding of alpine soil ecology remains limited. This study aimed to 1) determine whether the diversity and community composition of soil fungi vary across elevation gradients and to 2) assess the impact of woody shrub expansion on these patterns...

Artemisinin is an important drug for malaria treatment, which is exclusively produced in Artemisia annua . It's important to dissect the regulatory mechanism of artemisinin biosynthesis by diverse plant hormones and transcription factors. Our study shows ethylene, a plant hormone which accelerates flower and leaf senescence and fruit ripening, suppressed the expression of genes encoding three key enzymes ADS, DBR2, CYP71AV1, and a positive regulator AaORA involved in artemisinin biosynthesis. Then we isolated the gene encoding ETHYLENE-INSENSITIVE3 (EIN3), a key transcription factor in ethylene signaling pathway, by screening the transcriptome and genome database from Artemisia annua , named AaEIN3 ...

Two mealybug species (Hemiptera: Coccomorpha: Pseudococcidae), Pelionella osakaensis sp. n. and P. manifecta (Borchsenius, 1949), are described and illustrated based on adult female specimens collected in Japan, on the Japanese mugwort Artemisia indica Willd. var. maximowiczii (Nakai) H. Hara (Asteraceae). These are the first records of the occurrence of Pelionella species in East Asia. The new species is similar to P. grassiana (Goux, 1989) and P. proeminens (Goux, 1990), but differs in lacking multilocular pores with double loculi rings on the venter and in possessing dorsal cerarii and a circulus...

Models of the evolution of sexual cannibalism show that the frequency of male mating opportunities has significant impact on male choice and male risk aversion. In this study, we examined ecological components that should affect opportunities for multiple mating in wild populations of the Chinese mantid (Tenodera sinensis Saussure). While conducting mark-recapture studies of two field populations over the course of two seasons, along with Global Positioning System data on locations of individuals, we collected data on population densities, movement patterns, and individual ranges to estimate the overlap of adult males and female mantids...

BACKGROUND: Artemisia and Humulus pollen are the two most important aeroallergens of autumn allergies in North China. Cross-sectional data in 2001 have shown that allergic rhinitis often preceded or occurred at the same time as asthma in patients with autumn pollinosis in North China. OBJECTIVE: We used this cross-sectional data to investigate the association of serum specific IgE (sIgE) levels to Humulus and/or Artemisia pollen with the onset of asthma in patients with autumn pollen-induced allergic rhinitis...

The anti-malarial drug artemisinin is extracted from the leaves of Artemisia annua L. Due to toxicity to some microorganisms, the release of artemisinin from this medicinal plant in commercial cultivation might produce a potential risk for phosphorus (P) solubilizing bacteria (PSB). Therefore, the growth, P mobilization, and proton and organic acid efflux by two PSB isolates, Bacillus subtilis and Pseudomonas fluorescens, obtained from the soil without growing A. annua L. in history in the region for growing A...

Rupestine G is a guaipyridine sesquiterpene alkaloid isolated from Artemisia rupestris L. The total synthesis of rupestine G and its epimers was accomplished employing a Suzuki reaction to build a terminal diene moiety. The diene was further elaborated into the desired guaipyridine structure by a ring-closing metathesis reaction. Over all, rupestine G and its three epimers were obtained as a mixture in a sequence of nine linear steps with 18.9% yield. Rupestine G and its optically pure isomers were isolated by chiral preparative HPLC and fully characterized by 1 H ,13 C NMR, HRMS, optical rotation value, and experimental and calculated electronic circular dichroism spectroscopy...

Evasion strategies of intracellular parasites by hijacking cellular pathways, are necessary to ensure successful survival and replication. Eimeria tenella (E. tenella) has the ability to circumvent apoptosis of infected cells through increased expression of the transcriptional factor NF-κB and the anti-apoptotic factor Bcl-xL during the development of second generation schizonts. Artemisinin (ART) and its original plant, the dried leaves of Artemisia annua (LAA) have been shown to be effective against avian coccidiosis, however, the underlying mechanism remains unclear...

Currently, the most effective antimalarial is artemisinin, which is extracted from the leaves of medicinal herb Artemisia annua L. (A. annua). Previous studies showed that the complex chemical matrix of A. annua could enhance both the bioavailability and efficacy of artemisinin. The present study aims to evaluate the efficacy and pharmacokinetic properties of a combination therapy based on artemisinin and 3 components from A. annua with high content (arteannuin B, arteannuic acid, and scopoletin). In vivo antimalarial activity was assessed following a 4-day treatment in murine malaria models (Plasmodium yoelii and Plasmodium berghei)...

INTRODUCTION: Eupatilin, a pharmacologically active ingredient found in Artemisia asiatica, has been reported to have anti-oxidative, anti-inflammatory, and anti-apoptotic activities. However, molecular mechanisms underlying its anti-allergic properties are not yet clear. In this study, we investigated the effects of eupatilin on allergic inflammation in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells and a compound 48/80-induced anaphylactic shock model...

Eupatilin (5,7-dihydroxy-3',4',6-trimethoxyflavone) is a flavonoid compound from Artemisia species that possesses beneficial biological activities such as anti-cancer, anti-oxidation, and anti-inflammatory activities. However, an anti-adipogenic effect has not yet been reported. In this study, we found that eupatilin significantly inhibited the adipogenesis of 3T3-L1 adipocytes. Eupatilin decreased intracellular lipid accumulation and suppressed the expression level of key adipogenic regulators in 3T3-L1 adipocytes, including peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT-enhancer-binding protein alpha (C/EBPα), in a concentration-dependent manner...

Antihistamines are excreted into breast milk in small amounts; however, there are no adequate published studies or data concerning their effects on newborns and safety during breastfeeding. Thus, the development of sensitive and specific methodologies for the determination of antihistamines in breast milk is critical. A simple and sensitive GC-MS method for the simultaneous determination of eleven antihistamines (diphenhydramine, orphenadrine, chlorpheniramine, dimethindene, meclozine, hydroxyzine, loratadine, desloratadine, cetirizine, rupatadine and ebastine) in breast milk was developed and validated...

Artemisia argyi Lev. et Vant. (A. argyi) is widely utilized for moxibustion in Chinese medicine, and the mechanism underlying terpenoid biosynthesis in its leaves is suggested to play an important role in its medicinal use. However, the A. argyi transcriptome has not been sequenced. Herein, we performed RNA sequencing for A. argyi leaf, root and stem tissues to identify as many as possible of the transcribed genes. In total, 99,807 unigenes were assembled by analysing the expression profiles generated from the three tissue types, and 67,446 of those unigenes were annotated in public databases...

Understanding how annual climate variation affects population growth rates across a species' range may help us anticipate the effects of climate change on species distribution and abundance. We predict that populations in warmer or wetter parts of a species' range should respond negatively to periods of above average temperature or precipitation, respectively, whereas populations in colder or drier areas should respond positively to periods of above average temperature or precipitation. To test this, we estimated the population sensitivity of a common shrub species, big sagebrush (Artemisia tridentata), to annual climate variation across its range...
