kochia scoparia/edema

The 70% ethanol extract (KS-ext) from Kochiae Fructus (dried fruits of Kochia scoparia L.) was screened for its activity on nociceptive and inflammatory responses in experimental animals. Although KS-ext at an oral administration of 500 mg/kg had an antinociceptive effect on writhing responses

Cattle consuming only Kochia scoparia in a pasture southeastern Colorado became ill. Clinical signs were lacrimation, depression, anorexia, nystagmus, head pressing, and recumbency. Some cattle died acutely, with the only clinical signs being recumbency, nystagmus, and occasionally opisthotonos.

MeOH extract of Kochia scoparia was fractionated into CHCl3-, EtOAc- and BuOH extracts and the last fraction were hydrolyzed by 3%-NaOH (MeOH-H2O) to compare the bioactivities on antinociceptive and anti-inflammatory effects. Silica gel column chromatography of BuOH fraction afforded a large amount
