• The full detail of the chemical evidence on the structure of jegosapogenin (=21-O-tigloyl-barringtogenol C (Ia)), which was obtained along with barringtogenol C (I) and barringtogenol D (II) by acid hydrolysis of the pericarps saponin (=jegosaponin) of Styrax japonica SIEB. et ZUCC. (Styracaceae), is described. The structure of desacyl-jegosaponin, which is a common desacylated product of the saponin constituents of jegosaponin, and was prepared in a high yield by alkaline treat-ment of jegosaponin, has been established as barringtogenol C (3)-[β-D-glucopyranosyl-(1_<glu>→2_<glr>)][α-L-rhamnopyranosyl (1_<rham>→2_<gal>)-β-D-galactropyranosyl (1_<gal>→4_<glr>)]-β-D-glucuronopyranoside (VIf) on the basis of the chemical and physicochemical evidence.
