Actein (1), a tetracyclic triterpenoid from the rhizome of Cimicifuga racemosa (black cohosh), and 82 related triterpenoid and steroidal saponins isolated from higher plants were evaluated for anti-HIV activity as a continuing study to discover potential anti-AIDS agents from natural products. Actein showed potent activity and another twelve saponins showed moderate activity. The active compounds included two steroidal, seven tetracyclic triterpenoid, and four pentacyclic triterpenoid compounds.
