Eucalyptus camaldulensis: volatiles from immature flowers and high production of 1,8-cineole and beta-pinene by in vitro cultures.

Calli of Eucalyptus camaldulensis Dehn were induced, for the first time, from immature flowers and stamens and established in the presence of 2,4-D and BA, under dark and light conditions. Immature flowers, of the same type used for callus induction, were submitted to hydrodistillation while the induced calli were extracted with n-pentane. The constituents of the n-pentane extracts and of the hydrodistillate were identified by GC-MS.
