Geyu Liu, Huixia Ning, Nurbolati Ayidaerhan, Haji Akber Aisa
Because of the very similar morphologies and wide diversity of Artemisia L. varieties, they are difficult to identify, and there have been many arguments about the systematic classification Artemisia L., especially concerning the division of species. DNA barcode technology is used to rapidly identify species based on standard short DNA sequences. To evaluate seven candidate DNA barcodes (ITS, ITS2, psbA-trnH, rbcL, matK, rpoB, and rpoC1) regarding their ability to identify closely related species of the Artemisia genus in Xinjiang...

To evaluate the effect of Artemisia dracunculus on glycemic control, insulin sensitivity, and insulin secretion in patients with impaired glucose tolerance (IGT). A randomized, double blind, placebo-controlled clinical trial was performed in 24 patients with diagnosis of IGT. Before and after the intervention, glucose and insulin levels were measured every 30 min for 2 h after a 75-g dextrose load, along with glycated hemoglobin A1c (A1C) and lipid profile. Twelve patients received A. dracunculus (1000 mg) before breakfast and dinner for 90 days; the remaining 12 patients received placebo...

The chemical composition of an Italian oil of tarragon (Artemisia dracunculus L.) was analyzed by GC/EIMS. The major compound of the oil was estragole (73.3%), followed by limonene (5.4%), (E)-β-ocimene (5.3%), β-pinene (3.4%) and (Z)-β-ocimene (3.0%). The essential oil was tested "in vitro" for its antigermination activity against Raphanus sativus L., Lepidium sativum L, Papaver rhoeas L. and Avena fatua L. seeds and demonstrating a good inhibitory activity in a dose-dependent way.

Artemisia dracunculus L. (tarragon), a small shrubby perennial herb, is cultivated for the use of its aromatic leaves in seasoning, salads, etc., and in the preparation of tarragon vinegar. In the present work, genetic analysis of 29 cultivated individuals of this species was carried out employing 12 ISSR and 11 SRAP markers. A total of 59 (71.64%) and 79 (83.14%) polymorphic bands were detected by 12 ISSR primers and 11 SRAP primer pairs, respectively. High similarity for patterns of genetic diversity and clustering of individuals was observed using two ISSR and SRAP marker systems and combined data...

Artemisia extracts have been used as remedies for a variety of maladies related to metabolic and gastrointestinal control. Because the vagal afferent-nucleus of the solitary tract (NST) synapse regulates the same homeostatic functions affected by Artemisia, it is possible that these extracts may have activity at the synaptic level in the NST. Therefore, we evaluated how extracts of three common medicinal Artemisia species, Artemisia santolinifolia (SANT), Artemisia scoparia (SCO), and Artemisia dracunculus L (PMI-5011), modulate the excitability of the glutamatergic vagal afferent-NST synapse...

The objective of the present study was to examine the antitumor efficacy of the ethanol extract from Artemisia dracunculus as well as the compounds isolated from it on cultured EC‑109 esophageal squamous cell carcinoma (ESCC) cells. Apoptotic activities of the compounds were also studied using flow cytometry. EC‑109 esophageal cancer cells were treated with varying concentrations of compounds 1-7 isolated from the plant as well as the ethanol extract of Artemisia dracunculus. The cytotoxicity was evaluated by MTT assay and the apoptotic studies of the compounds were determined using flow-cytometry...

OBJECTIVE: An increase in ectopic lipids in peripheral tissues has been implicated in attenuating insulin action. The botanical extract of Artemisia dracunculus L. (PMI 5011) improves insulin action, yet the precise mechanism is unknown. The aim of this study was to determine whether the mechanism by which the bioactive compounds in PMI 5011 improve insulin signaling is through regulation of ceramide metabolism. METHODS: L6 Myotubes were separately preincubated with 250 μM palmitic acid with or without PMI 5011 or four bioactive compounds isolated from PMI 5011 and postulated to be responsible for the effect...

OBJECTIVES: A botanical extract from Artemisia dracunculus L., termed PMI 5011, has been shown to improve insulin sensitivity by increasing cellular insulin signaling in in vitro and in vivo studies. These studies suggest that PMI 5011 effects changes in phosphorylation levels of proteins involved in insulin signaling. The aim of this study was to explore the effects of this promising botanical extract on the human skeletal muscle phosphoproteome, by evaluating changes in site-specific protein phosphorylation levels in primary skeletal muscle cultures from obese, insulin-resistant individuals stimulated with and without insulin...

OBJECTIVE: Scientifically validated food-based interventions are a practical means of addressing the epidemic of metabolic syndrome. An ethanolic extract of Artemisia dracunculus L. (PMI-5011) containing bioactive polyphenols, such as 2', 4'-dihydroxy-4-methoxydihydrochalcone (DMC-2), improved insulin resistance in vitro and in vivo. Plant polyphenols are concentrated and stabilized when complexed to protein-rich matrices, such as soy protein isolate (SPI), which act as effective food-based delivery vehicles...

OBJECTIVE: Obesity is linked to insulin resistance, a primary component of metabolic syndrome and type 2 diabetes. The problem of obesity-related insulin resistance is compounded when age-related skeletal muscle loss, called sarcopenia, occurs with obesity. Skeletal muscle loss results from elevated levels of protein degradation and prevention of obesity-related sarcopenic muscle loss will depend on strategies that target pathways involved in protein degradation. An extract from Artemisia dracunculus, termed PMI 5011, improves insulin signaling and increases skeletal muscle myofiber size in a rodent model of obesity-related insulin resistance...

AIMS: Bioactives of Artemisia dracunculus L. (termed PMI 5011) have been shown to improve insulin action by increasing insulin signalling in skeletal muscle. However, it was not known if PMI 5011's effects are retained during an inflammatory condition. We examined the attenuation of insulin action and whether PMI 5011 enhances insulin signalling in the inflammatory environment with elevated cytokines. METHODS: Muscle cell cultures derived from lean, overweight and diabetic-obese subjects were used...

Impaired insulin signaling is a key feature of type 2 diabetes and is associated with increased ubiquitin-proteasome-dependent protein degradation in skeletal muscle. An extract of Artemisia dracunculus L. (termed PMI5011) improves insulin action by increasing insulin signaling in skeletal muscle. We sought to determine if the effect of PMI5011 on insulin signaling extends to regulation of the ubiquitin-proteasome system. C2C12 myotubes and the KK-A(y) murine model of type 2 diabetes were used to evaluate the effect of PMI5011 on steady-state levels of ubiquitylation, proteasome activity and expression of Atrogin-1 and MuRF-1, muscle-specific ubiquitin ligases that are upregulated with impaired insulin signaling...

Chamomile (Matricaria chamomilla L.), tarragon (Artemisia dracunculus L.) and Mexican arnica (Heterotheca inuoides) are common compositae spices and herbs found in the US market. They contain flavonoids and hydroxycinnamates that are potentially beneficial to human health. A standardized LC-PDA-ESI/MS profiling method was used to identify 51 flavonoids and 17 hydroxycinnamates. Many of the identifications were confirmed with authentic standards or through references in the literature or the laboratory's database...

Insulin resistance is a major pathophysiologic abnormality that characterizes metabolic syndrome and type 2 diabetes. A well characterized ethanolic extract of Artemisia dracunculus L., termed PMI 5011, has been shown to improve insulin action in vitro and in vivo, but the cellular mechanisms remain elusive. Using differential proteomics, we have studied mechanisms by which PMI 5011 enhances insulin action in primary human skeletal muscle culture obtained by biopsy from obese, insulin-resistant individuals...

Ectopic lipids in peripheral tissues have been implicated in attenuating insulin action in vivo. The botanical extract of Artemisia dracunculus L. (PMI 5011) improves insulin action, yet the precise mechanism is not known. We sought to determine whether the mechanism by which PMI 5011 improves insulin signaling is through regulation of lipid metabolism. After differentiation, cells were separately preincubated with free fatty acids (FFAs) and ceramide C2, and the effects on glycogen content, insulin signaling, and ceramide profiles were determined...
