The steroidal alkaloid veratramine shows a variety of toxic actions and pharmacological activities. It is believed that veratramine has cardiac activity, antitumor activity and central action. Veratramine has also been recognized as a 5-HT agonist. The mechanisms of these toxic actions and pharmacological activities were investigated. In previous reports, microbial biotransformation of veratramine was carried out with two types of fungi (Nocardia species ATCC 21145 and Cunninghamella echinulata). Rings A and B of veratramine were transformed and seven new metabolites were identified. The toxic actions and pharmacological activities of veratramine, the corresponding mechanisms together with the microbial biotransformation of veratramine are reviewed in this paper.
