Chinese Magnoliae Cortices (commercial Chinese Magnoliae Cortex and cortices of Magnolia officinalis var. biloba and Magnolia officinalis) were examined for their quaternary alkaloids and the results were compared with those of Japanese Magnoliae Cortex. Six alkaloids, (-)-magnocurarine, (-)-magnoflorine, (+)-laurifoline, (±)-oblongine, (+)-menisperine, and (+)-xanthoplanine, were found in both Chinese and Japanese samples. The quaternary alkaloid contained in Chinese Magnoliae Cortex but not in Japanese Magnoliae Cortex (cortex of M. obovata) was purified by preparative ion-pair HPLC using sodium perchlorate, and characterized mainly by the two-dimensional NMR techniques to be (-)-10-demethylcryptaustoline, a new alkaloid having dibenzopyrrocoline skelton.
