Abstract
Two new Lycopodium alkaloids, 4β-hydroxynankakurine B (1) and Δ(13,N),N(α)-methylphlegmarine-N(β)-oxide (2), together with three known analogues, lycoposerramine E (3), nankakurine B (4) and lobscurinol (5), were isolated from Phlegmariurus phlegmaria. Their structures were established by mass spectrometry and 1D and 2D NMR techniques.
Keywords:
