Alkaloids represent an important group of therapeutically significant secondary metabolites. The plants of the genus Veratrum contain alkaloids with an antihypertensive effect. Also the genera Schoenocaulon and Zygadenus are sources of veratrum alkaloids. The present paper presents a survey of isolated alkaloids from the underground and aerial parts of 17 species of the genus Veratrum. The alkaloids occur as glycosides, aglycones or in the form of esters with various acids. In conformity with the IUPAC regulations for the nomenclature of steroids, Veratrum alkaloids were divided into 7 groups. The present paper lists the compounds of the first two groups, i.e. (1) alkaloids of the jervanine and veratranine types (I-XXIII), and (2) alkaloids with the cevanine skeleton (XXIV-XXXV). The individual compounds are characterized by their physico-chemical constants (melting point, optical rotation).
