Like other ergoline alkaloids, it occurs in various species of vines of the Convolvulaceae (morning glory) family and in some species of lower fungi. Ergocristine is one of 3 similar peptides referred to as ergotoxine alkaloids, the other two being ergocryptine and ergocornine. Ergotoxines prepared into their hihydroergotoxine mesylates, commonly known as ergoloid mesylates, are used in the symptomatic therapy of age-related dementia. Long term exposure to some ergoline alkaloids can cause ergotism, a disease causing convulsive and gangrenous symptoms. (L1918, A2915)"}]
