Changes in Triterpenoid Content during the Growth Cycle of Cultured Plant Cells

Abstract
Similar changes in the pentacyclic triterpenoid contents were observed during the growth cycle of Datura innoxia, Luffa cylindrica and Lycopersicon esculentum seedling callus cells in batch culture. Triterpenoid contents decreased for several days after callus inoculation, then increased rapidly during the mid and late exponential phases of growth.
