sonchus acuminatus/항균

The total phenolic and flavonoid, antioxidant and antibacterial activities of six Sonchus wild vegetables (Sonchus oleraceus L., Sonchus arvensis L., Sonchus asper (L.) Hill., Sonchus uliginosus M.B., Sonchus brachyotus DC. and Sonchus lingianus Shih) in China were investigated. The results revealed

BACKGROUND Chamomile (Chamaemelum nobile) is widely used throughout the world, and has anti-inflammatory, deodorant, bacteriostatic, antimicrobial, carminative, sedative, antiseptic, anti-catarrhal, and spasmolytic properties. Because of the increasing incidence of drug-resistant bacteria, the

Two new sesquiterpene lactones, 1beta-sulfate-5alpha, 6betaH-eudesma-3-en-12, 6alpha-olide (1) and 1beta-(p-hydroxyphenyl acetyl)-15-O-beta-D-glucopyranosyl-5alpha, 6betaH-eudesma-3-en-12, 6alpha-olide (2) were isolated from Sonchus arvensis L. (Asteraceae), together with eight known compounds.

Four new eudesmanolides were isolated from the whole plant of Sonchus transcaspicus and their structures were elucidated by means of spectroscopic methods, including 2D-NMR (1H-1H COSY, HMQC, HMBC and NOESY) and NOEDS (NOE difference spectra) as 1beta-O-beta-D-glucopyranosyl-5alpha,6beta

Sonchus asper is an exotic annual herb belonging to the Asteraceae family. Crude extracts of S. asper leaves have antiphlogistic and antibacterial properties. In May 2011, severe infection of powdery mildew was observed on S. asper in Henan Province, a central area of China. Symptoms began as small,

A new phytotoxic enol tautomer of 4-pyridylpyruvic acid, named ascosonchine, was isolated from the culture filtrate of Ascochyta sonchi. Such a leaf pathogen is a potential biocontrol agent of Sonchus arvensis, a perennial herbaceous weed occurring throughout the temperate regions of the world.
