Studies on the Alkaloids of Formosan Lauraceous Plants. XIV. : Alkaloids of Actinodaphne acutivena (HAYATA) NAKAI and Litsea hayatae KANEHIRA

Abstract

Examinations were made on the alkaloidal components in the trunk wood of Actinodaphne acutivena (HAYATA) NAKAI (Japanese name 'Nagami-kurodamo') and in the trunk bark and wood of Litsea hayatae KANEHIRA(Japanese name 'Hirohadamo') (Lauraceae). Laurolitsine (I) was isolated and identified from the former, and I, ushinsunine (II), and liriodenine (oxoushinsunine) (III) from the latter.
