Fig. 1From: Transcriptome and metabolome analysis to reveal major genes of saikosaponin biosynthesis in Bupleurum chinenseDiagrammatic representation of the biosynthetic pathway for triterpenoid saponins in B. chinense. The universal precursor β-amyrin is converted by a series ofoxidative reactions to saikosaponin A and saikosaponin D.
