Alkaloids of Nandina domestica f. shinananten HORT

Abstract

Alkaloids were examined in Nandina domestica forma shinananten HORT. (Japanese name “Shina-nanten”) and alkaloids listed in Table I were identified. Leaves of several kinds of Japanese Nandina and Mahonia genera were examined and bases contained in them are also listed in Table I. It is taxonomically interesting that a large quantity of protopine was found in the leaves of Nandina domestica forma shinananten, a forma of the Nandina genus, while this alkaloid was not detected in the leaves of other Nandina and Mahonia genera.
