Screening of anti-biofilm compounds from the burdock leaf based on metabolomics is reported here. The crystal violet assay indicated 34% ethanol elution fraction of burdock leaf could completely inhibit biofilm formation of Pseudomonas aeruginosa at 1 mg·mL(-1). Then, the chemical composition of burdock leaf fraction was analyzed by ultra-performance liquid chromatography-mass spectrometry (UPL...

Root of burdock contains high amounts of dietary fibers and polyphenols. To improve the functional properties, the root was fermented with Aspergillus awamori. Effect of the fermented burdock on alloxan-induced mouse diabetes was examined. A diet containing the 5% fermented burdock powers was prepared to examine effect of the burdock diet on alloxan-induced mouse diabetes. Mice fed the burdock ...

BACKGROUND Arctium species (Asteraceae) are distributed worldwide and are used as food and rich sources of secondary metabolites for the pharmaceutical industry, e.g., against avian influenza virus. RNA silencing is an antiviral defense mechanism that detects and destroys virus-derived double-stranded RNA, resulting in accumulation of virus-derived small RNAs (21-24 nucleotides) that can be use...

The major trend in the antioxidant market is the growing consumer demand for natural antioxidants. Tea, one of the most widely consumed beverages in the world, is an easy way to obtain antioxidant components from a natural source. Our objective was to develop burdock root tea (BRT) with potent antioxidant activity and good color quality. In order to obtain maximum antioxidant activity and quali...

Burdock roots are healthy dietary supplements and a kind of famous traditional Chinese medicine, which contains large amounts of caffeoylquinic acid derivatives. However, little research has been reported on the preparative separation of these compounds from burdock roots. In the present study, a combinative method of HSCCC and semi-preparative HPLC was developed for the semi-preparative separa...

conclusions the crude hydroalcoholic extract of burdock root was found to cause better outcomes in the healing process, acute inflammation, and fibrosis on the 7th, 14th, and 21st day postoperatively. objectives in this experimental study, 36 male wistar rats each weighting approximately 200 - 220 g were studied in six groups, each with 6 animals for 21 days. hydroalcoholic extract of burdock r...

BACKGROUND We have previously reported on the variation of total fructooligosaccharides (FOS), total inulooligosaccharides (IOS) and inulin in the roots of burdock stored at different temperatures. During storage at 0°C, an increase of FOS as a result of the hydrolysis of inulin was observed. Moreover, we suggested that an increase of IOS would likely be due to the synthesis of the IOS by fruct...

Antrodia cinnamomea is a valuable fungus. The 4-acetylantroquinonol B (4-AAQB) contained in it has strong anticancer activity. In this study, five kinds of herbs, burdock, wolfberry, coix seed, hawthorn, and tangerine peel were selected processed into powders, aqueous extracts, ethanolic extracts to investigate the effects on production 4-AAQB by A. cinnamomea. A combination strategy was conduc...

Arctium lappa L, popularly known as burdock, is a medicinal plant with wide application in chinese folk medicine. The objective of the present work was to proceed hydroethanolic extraction leaves, analyze chemical compounds proteins, phenols, antioxidants, phytochemical and its skin healing potential exposed cutaneous lesions rats treated gel containing extract. For preparation extract, fresh l...
