BACKGROUND
The low larkspurs (Delphinium nuttallianum and D. andersonii) are two toxic plant species that are often fatally ingested by cattle on western USA rangelands. To assess the potential toxicity of the plants, methods are needed to identify and quantify the toxic
A new N-(methylsuccinimido)anthranoyllycoctonine norditerpenoid alkaloid, geyerline, has been isolated and characterized from extracts of the poisonous larkspur Delphinium glaucum. A previously described norditerpenoid alkaloid, grandiflorine, has also been isolated from Delphinium geyeri. Both
From the aerial parts of four Delphinium species 11 known and 3 new norditerpenoid alkaloids have been isolated: from D. dissectum Huth: delavaine A/B, deoxylycoctonine, methyllycaconitine; new: 10-hydroxymethyllycaconitine; from D. excelsum Reichenb.: delcaroline, delectinine, delterine,
