Studies on the Alkaloids of Rutaceous Plants. XVI

Alkaloids of Xanthoxylum schinifolium SIEB. et ZUCC. (Fagara schinifolia (SIEB. et ZUCC.) ENGL.). (1)

Abstract

Alkaloidal components were examined in the cortex of Xanthoxylum schinifolium SIEB. et ZUCC. (Fagara schinifolia (SIHB. et ZUCC.) ENGL.) (Rutaceae) (Japanese name “Inu-zansho”) growing on Mount Ibuki. Besides a tertiary base, skimmianine (I), a neutral substance, aesculetin dimethyl ether (II), was isolated. On the other hand, presence of a comparatively large amount of quaternary base was detected but the base seemed to be extremely labile and underwent decomposition during extraction.
