Studies on the Constituents of Kalopanax Pictum Nakai var Typicum Nakai ( II ) - Isolation and Identification of Hederine-

해동피성분(海桐皮成分)에 관(關)한 연구(硏究) ( II ) - Hederine의 분리(分離)및 동정(同定)에 대(對)하여 -

Hederine, m. p. $256{\sim}257^{\circ}\;C_{41}H_{64}O_{11}\;{\cdot}\;2H_{2}O$ : $23-hydroxy-3{\beta}-({\beta}-{\alpha}-arabinosidor hamnoside)-olenana-12-ene-oique,$ 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.
