Objective: This research was to study the anti-inflammatory and analgesic effects of Climbing Groundsel Herb ethanol extracts. And observe its mechanism of action preliminarily. Methods: HAC writhing reaction and hot plate test were used to observe the analgesic effect of senecio. The mouse ear swelling induced by xylene, the rat granulation tissue hyperplasia induced by cotton ball and rat egg...

Twenty-seven pyrrolizidine alkaloids were identified by a detailed phytochemical study and GC/MS analysis on twelve Bulgarian species from genus Senecio. Twenty of them are new for the corresponding species. Other six structures remain tentatively identified.

From a methanol extract of dried-ground aerial parts of Senecio lyratus, an anti-fungal and anti-bacterial active compound was isolated and identified as beta-sitosterol by spectroscopic analysis.

A new species of Asteraceae from Taiwan, Senecio kuanshanensis C.-I Peng & S.W. Chung, a distinct member of sect. Crociseris (Reichenb.) Hall. & Wohlf. ser. Nemorenses Gagnidze, is described and illustrated. Senecio kuanshanensis is apparently rare, presently known only from mountain ridges of Kuanshan, at (2,500-)3,000-3,300 m elevation in the southern part of the Central Mountain Range of Tai...

Pyrrolizidine alkaloids (PAs) are found in various plant genera worldwide. Poisoning by PA-containing plants is usually accidental, by the ingestion of grain inadvertently contaminated with seeds of pyrrolizidine-containing weeds, or the consumption of herbal or bush tea, or when taken as herbal infusions for medicinal purposes. In this paper the toxicity of PA-containing plants, with emphasis ...

The furanoeremophilanes 6 beta-angeloyloxy-1,10-dehydrofuranoeremophilan-9-one (1), 6 beta-hydroxy-1,10-dehydrofuranoeremophilan-9-one (2) and 6 beta-propionyloxy-1,10-dehydrofuranoeremophilan-9-one (3) were isolated from Senecio otites, their structures elucidated by spectral analyses, and their insecticidal and phytotoxic properties evaluated. Compounds 1-3 proved to be effective aphid antife...
