Spörle, Jörg | Becker, Hans | Allen, Noris Salazar | Gupta, Mahabir P.
An axenic culture of Symphyogyna brongniartii has been initiated from spores on modified Benecke medium. Growth was best on Gam borg B5 medium with 0.3% sucrose, with a doubling time of 36 days. The culture produced the same terpenoids as plants growing in their natural habitat, perrottetianal A being the major constituent. Also found were bicyclogermacrene, β-barbatene, δ-selinene, β-cubebene, spathulenol, and (-)-geosm in . The latter compound was hitherto only known from microorganisms. Synthesis rate of terpenoids during the passage period and quantitative differences in terpenoid production on different mineral media were investigated.
