Estragon and thyme extracts showed potent inhibitory activities against chemical mediator release from rat basophilic leukemia RBL-2H3 cells. 7-Methoxycoumarin was isolated from estragon, and 5,4'-dihydroxy-6,7,3'-trimethoxyflavone, 5,4'-dihydroxy-6,7,8,3'-tetramethoxyflavone,
Thymus schimperi is a highly localized and a rare plant endemic to Ethiopia. An optimized and validated high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-ESI-MS/MS) method was applied to characterize 23 polyphenolic compounds found in ethyl acetate
The infusions of Thymus pallescens Noë, Saccocalyx satureioides Coss. et Dur., Ptychotis verticillata Briq. and Limoniastrum guyonianum Boiss. have been used as medicinal remedies for many diseases in Algerian folk medicine. These species have also been well documented as rich sources of
BACKGROUND
In order to survive in food-processing environments and cause disease, Campylobacter jejuni requires specific survival mechanisms, such as biofilms, which contribute to its transmission through the food chain to the human host and present a critical form of resistance to a wide variety of
Flavonoids from Thymus vulgaris L. have been studied in vitro for spasmolytic activity on the smooth muscles of the guinea-pig ileum and trachea and of the rat vas deferens. The flavones and thyme extracts inhibit responses to agonists which stimulate specific receptors (acetylcholine, histamine,
BACKGROUND
Extracts from Thymus vulgaris L. and Thymus zygis L. are traditionally used for bronchitis, catarrhs of the respiratory tract and supportive treatment of pertussis. A potential spasmolytic effect is thought to be due to the presence of the monoterpenoid phenols thymol and carvacrol in the
Thymus plants are marketed for diverse usages because of their pleasant odor, as well as high nutritional value and wealth of health-promoting phytochemicals. In this study, Thymuszygis, Thymuspulegioides, and Thymusfragrantissimus grown under organic cultivation regime were characterized regarding
Thymus herba-barona, Thymus pseudolanuginosus, and Thymus caespititius decoctions were screened for their phenolic constituents, along with their potential antioxidant, anti-inflammatory, and antibacterial activities. The total phenolic compounds in the extracts of the three plants ranged from 236.0
Flavonoids are polyphenolic compounds that not only impart coloration to plants and fruits, but also protect plants from pathogens, radiation, etc. They serve as a nutrient to plants and possess immense anti-oxidant properties. Research has shown that they exhibit anti-inflammatory, anti-cancer, and
A highly polymethylated flavone that effectively inhibited cytochrome P450s (CYPs) 1A2 and 3A4 (IC(50) = 2.41 and 1.71 µM) in vitro was isolated from thyme leaves (Thymus saturoides) purchased from a Japanese market. Its structure was spectroscopically identified as
We compared the phenolic metabolites and antioxidant activities of Thymus lotocephalus G. López & R. Morales wild plants and in vitro cultures using different extraction solvents. HPLC-DAD analysis allowed the identification and quantification of phenolic (caffeic and rosmarinic) acids and flavones
Breast cancer is one of the most common causes of the death among women worldwide. Metabolic disorders, alcohol consumption, hormone replacement therapy, genetic susceptibility and not having children are well known risk factors for breast cancer. Surgical resection, radiation therapy, and
The effects of temperature (50-200 °C) and contact time (5-30 min) on the pressurized hot water extraction of deodorized thyme were explored for antioxidant activity, polyphenol profiles, and total antioxidants. Six not previously reported polyphenolic compounds were identified in thyme. An inverse
Epidemiological evidence suggests that flavonoids may play an important role in the decreased risk of chronic diseases associated with a diet rich in plant-derived foods. Flavonoids are also common constituents of plants used in traditional medicine to treat a wide range of diseases. The purpose of
