Essential oils from Artemisia species inhibit biofilm formation and the virulence of Escherichia coli EPEC 2348/69.
Abstract
Enteropathogenic Escherichia coli E2346/69 (EPEC) has caused foodborne outbreaks worldwide and the bacterium forms antimicrobial-tolerant biofilms. The anti-biofilm formation of various components of essential oils extracted from selected medicinal plants were investigated and tested on EPEC and wild strains of E. coli. Oils extracted from the family Asteraceae and their major common constituents at 0.031 and 0.062% (V/v) were found to significantly inhibit biofilm formation without affecting the growth of planktonic cells. In addition, three plants belonging to this family (Artemisia herba alba, ...

In vitro and in vivo biological activities of azulene derivatives with potential applications in medicine
AbstractAzulene is an aromatic hydrocarbon that possesses a unique chemical structure and interesting biological properties. Azulene derivatives, including guaiazulene or chamazulene, occur in nature as components of many plants and mushrooms, such asMatricaria chamomilla,Artemisia absinthium,Achillea millefolium, andLactarius indigo. Due to physicochemical properties, azulene and its derivatives have found many potential applications in technology, especially in optoelectronic devices. In medicine, the ingredients of these plants have been widely used for hundreds of years in antiallergic, antibacterial, and anti-inflamma...

High-defined quantitative snapshots of the ganglioside lipidome using high resolution ion mobility SLIM assisted shotgun lipidomics.
Abstract
Defects in sphingolipid metabolism have emerged as a common link across neurodegenerative disorders, and a deeper understanding of the lipid content in preclinical models and patient specimens offers opportunities for development of new therapeutic targets and biomarkers. Sphingolipid metabolic pathways include the formation of glycosphingolipid species that branch into staggeringly complex structural heterogeneity within the globoside and ganglioside sub-lipidomes. Characterization of these sub-lipidomes has typically relied on liquid chromatography-mass spectrometry-based (LC-MS) approaches, but...

Sparrows use a medicinal herb to defend against parasites and increase offspring condition.
Abstract
The incorporation of aromatic plants into nests by birds is suspected to constitute an example of preventative medicine use, whereby the phytochemical compounds within plants reduce infestation by parasites and increase offspring condition [1,2]. In China, russet sparrows (Passer cinnamomeus) incorporate wormwood (Artemisia verlotorum) leaves into their nests around the same time that local people hang wormwood from their doors as a traditional custom during the Dragon Boat Festival. The belief that this behaviour confers protection against ill health [3] is supported by the description of anti-pa...

Methanolic extract of Artemisia absinthium prompts apoptosis, enhancing expression of Bax/Bcl-2 ratio, cell cycle arrest, caspase-3 activation and mitochondrial membrane potential destruction in human colorectal cancer HCT-116 cells.
This study aims to assess the anticancer activity of the methanolic extract of A. absinthium (MEAA) against human colorectal cancer HCT-116 cell line. The cytotoxic effects of MEAA on HCT-116 cells was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. The expression levels of BAX and BCL-2 in HCT-116 cell line were examined by qRT-PCR. Annexin V/PI-flow cytometry technique was used to detect the cell cycle and apoptosis. MMP was predicted by Rhodamine 123 staining, and caspase 3 activity was analyzed by ELISA. Western blot method was performed to detect the expression level of BAX, Bcl-2 and Ca...

Chemotypic variation of non-volatile constituents of Artemisia afra (African wormwood) from South Africa.
Abstract
Artemisia afra, (African wormwood) is a popular medicinal plant of southern Africa and is an excellent candidate for commercialisation. This current study was aimed at exploring the phytochemistry and chemical variation of non-volatile compounds within wild populations of A, afra, and developing chromatographic quality control protocols for raw materials based on the identification of marker compounds. Chromatographic data, from samples representing 12 distinct populations were obtained using liquid chromatography-mass spectrometry. An untargeted chemometric approach revealed three clusters. Marke...

The Effect of Auxin and Auxin-Producing Bacteria on the Growth, Essential Oil Yield, and Composition in Medicinal and Aromatic Plants.
Abstract
Aromatic plants had been used since ancient times for their preservative and medicinal properties, and to impart aroma and flavor to food. Also their secondary metabolites are economically important as drugs, flavor and fragrances, pharmaceuticals, agrochemicals, dye, and pigments, pesticides, cosmetics, food additives, other industrially biochemical, and also play a major role in the adaptation of plants to their environment. Indole acetıc acid-producing rhizobacteria inoculations increase in stomatal density and level of secondary metabolite and have a synergistic effect on monoterpene biosynt...
