Abstract
A callus culture of Aleurites fordii Hemsley (Euphorbiaceae) producing five galloylglucoses and an ellagitannin, geraniin, was established. The production of pentagalloylglucose was remarkably enhanced under light irradiation compared with that in the dark. Cell growth and tannin production were also greatly affected by changing the concentrations and composition of nitrogen sources.
