GC/MS Examination of Lycopodium Extracts for Alkaloid Content [PDF]

open access: yes, 1985
Plants of the Lycopodium species have long been known to elaborate alkaloids. Over one hundred alkaloids have been isolated from these plants, but no efficient method exists to quickly screen plants to determine their alkaloid content.

Serratinine: A novel skeletal lycopodium alkaloid

open access: yesTetrahedron Letters, 1966
Serratinine, one of major alkaloids of Lycopodium serratum THUNB. var. Thunbergii MAKINO, is a tetracyclic new alkaloid possessing an expanded formula, C10H15(〓CH-OH)(〓CH-OH)(〓CH-CH3)(-COCH2-) (-N-). On the basis of chemical and spectroscopic data, the partial structure (C) for serratinine was proposed.
