The isolation of both basic and neutral components of Lycopodium clavatum L. was attempted and lycopodine, L30 from basic component, as well as sucrose, a-onocerin and two kinds of new terpenes, such as lycoclavanol, m.p. 308-310°, [α]₁₃ -23.1°, C₃₀H₅₀O₃, and lycoclavanin, m.p. 344-346°, (acetate: m.p. 236-237°, [α]ᴰ -32.2°), C₃₀H₄₆O₅ from neutral component were isolated.
