Together with the ester-alkaloids protoverine and germine, the combined alkaloids obtained by ether extraction of the epigeal part of Veratrum dahuricum (Turcz.) Loes. yielded seven alkaloids (I-VII) with specific Rf values in two chromatographic systems. These alkaloids were identified as rubijervine (I), veramarine (II), veratroylzygadenine (III), jervine (IV), isorubijervine (V), verazine (VI), and veramine (VII), with (I)-(III) and (V)-(VII) being isolated from this plant for the first time. Additionally, the alkaloids of Buxus sempervirens L. cultivated in Kobileti, Adzharsk ASSR were studied for the first time. The total alkaloid contents in various organs (first year shoots, young roots, flowers, leaves and thin twigs, roots, perennial flowers, fruit) collected on April 15 and July 28, 1982 were determined by the chloroform method. The combined alkaloids were a complex mixture, so the ethereal fraction from thin twigs and leaves (collected on April 15, 1982) was separated by basicity using McIlvaine's solutions (pH 8.0-2.2) and then chromatographed on an alumina column with ether-ethanol mixtures containing increasing concentrations of ethanol (5%, 10%, 15%, 20%, 25%, 30%, and 40%).
