RESUMO
Cell suspension cultures of Tabernaemontana catharinensis were treated with autoclaved homogenates of Candida albicans, Fusarium oxysporum, Penicillium avelanium and Saccharomyces cerevisiae. The effects caused by the concentration, exposure time and the type of elicitor on the accumulation of pentacyclic triterpenes were monitored. When exposed to biotic elicitors for longer periods, some cell lines redoubled the production of those triterpenes. Saccharomyces cerevisiae homogenate was the best elicitor of triterpenes in all cell lines investigated.
