eupatorium japonicum/necrosis

Tenuazonic acid (TeA), a nonhost-specific phytotoxin produced by Alternaria alternata, was determined to be a novel natural photosynthesis inhibitor owning several action sites in chloroplasts. To further elucidate the mode of its action, studies were conducted to assess the production and

Regular ingestion of Eupatorium adenophorum [Ageratina adenophora (Spreng.)] or Crofton weed causes chronic pulmonary disease in horses mainly in Australia, New Zealand, and the Himalayas. The disease is characterized by pulmonary interstitial fibrosis, emphysema, alveolar epithelisation and reduced

Search for a novel anti-inflammatory agent from a herbal source, such as Eupatorium adenophorum Spreng., a plant from the Eastern Himalayas, is of prime interest in the present investigation. Inflammation causes tissue destruction and development of diseases such as asthma, rheumatoid arthritis, and

The oral LD50 of Crotalaria assamica, which contains mainly monocrotaline, was found to be 154 mg/kg in mice. Neither liver necrosis nor morbidity was demonstrated with Eupatorium extract at a dose level of 144 mg/kg, which was equivalent to the LD20 of Crotalaria. Pretreatment with phenobarbitone

Freeze dried Eupatorium adenophorum leaf powder mixed in rat feed at a level of 25% elicited hepatotoxicity. The affected animals were jaundiced and had marked increase in plasma bilirubin levels and activities of alkaline phosphatase, glutamate oxaloacetate transaminase and glutamate pyruvate

Eupatorium adenophorum leaves cause hepatotoxicity and cholestasis in rats. The hepatotoxicant has been characterized as 9-oxo-10,11-dehydroageraphorone (ODA), a cadinene sesquiterpene. Oral administration of ODA, mixed in feed to rats, caused jaundice in 24 h. The liver of the intoxicated animals

Eupatorium adenophorum (Crofton weed), a native of Central America. has appeared as a major weed in several areas in different parts of the world. Horses that eat this plant are poisoned on prolonged exposure. Toxicity due to consumption of this plant by other grazing animals is not clear.

Eupatorium lindleyanum DC., "Ye-Ma-Zhui" called by local residents in China, showed anti-inflammatory activity and is used to treat tracheitis. We had isolated and identified the flavonoids, diterpenoids and sesquiterpenes compounds from the herb. In the present study, we evaluated the protective

BACKGROUND Eupatorium lindleyanum DC. is widely used for its efficiency in treating cough, tracheitis and tonsillitis. Acute lung injury (ALI) induced by lipopolysaccharide (LPS) in mice was used to investigate therapeutic effects and possible mechanism of the sesquiterpenes fraction of E.

BACKGROUND Aerial parts of Eupatorium perfoliatum have been traditionally used by American natives as a treatment for fever and infections. Also modern phytotherapy in Europe documents the use of hydroalcoholic extracts of this herbal material for the treatment of infections of the upper respiratory

The aim of the work was the investigation of pharmacological activity of unique dihydroflavonol glycoside, micranthoside, extracted from the leaves Eupatorium micranthum Less. introduced into Georgia. Mature human T-cell leukemia cell lines (Jurkat) were analyzed in the study under the modeled
