Production of macrocyclic ellagitannin oligomers by Oenothera laciniata callus cultures.
Callus cultures of Oenothera laciniata grown on LS agar medium supplemented with IAA and kinetin produced large amounts of the macrocyclic ellagitannin dimer, oenothein B, and a trimer, oenothein A, accompanied with related monomeric hydrolysable tannins. The content of the main compound oenothein B (65 mg/g dry wt) in calli cultured on modified LS medium containing 10 mM NH4+ and 5 mM NO3- was nearly two times higher than that in intact leaves.
