Hederine, m. p. 256∼257° C_(41)H_(64)O_(11)·2H₂O : 23-hydroxy-3β(β-α-arabinosidor hamnosido)-oleana-l2-ene-oique, was obtained from the cortex of Kalopanax pictum. Acid hydrolysis of hederine yielded hederagenin, arabinose and rhamnose. Hederagenin was identified by comparison of it`s mixed melting point and IR spectra against authentic sample. Arabinose and rhamnose were identified by TLC against standards.
