✦ Synopsis

Aphelandrine (1) is shown to be biosynthesized in the root cells of Aphelundra tetragonu (VAHL) NEES from labelled putrescine (4), spermidine (5), and cinnamic acid (3). Whether spermine (6) and the @-hydroxycinna-moy1)spermidine 8 are precursors of 1 is uncertain, since the latter is hydrolysed to a large extent before incorporation, and the former is metabolized to 4 and 5. Methionine (7) is the source of the 3-aminopropyl unit of 5 and 6.
