摘要

Three new C27N3-type Lycopodium alkaloids, serramyuines A–C (1–3) were isolated from Lycopodim serratum Thunb. var. serratum and their structures including relative configurations were elucidated on the basis of spectroscopic data. Serramyuines A and B (1 and 2) feature a new lucidine-type skeleton with an N-1 to C-11 connection and an α-hydroxy group at C-14 and serramyuine C (3) is a stereoisomer of lycolucine.
