从关白附子(Aconitum koreanum R.Raymund)中共分得六种生物碱。其中一种是已知生物碱,卽次乌头碱,另五种为新生物碱,暂称为关附甲素C_(24)H_(31)O_6N、乙素C_(22)H_(29)O_5N、丙素C_(22)H_(33)O_2N、丁素C_(24)H_(35)O_3N及戊素C_(29)H_(43)O_7N。关附甲素是关附乙素的一乙酸酮。关附甲素、乙素、丙素的示性式分别定为:C_(19)H_(20)(OH)_2(CH_3COO)_2(CH_3)(∶N·),C_(19)H_(20)(OH)_3(CH_3COO)(CH_3)(∶N·),C_(19)H_(23)(OH)_2(CH_3)(N—C_2H_5)。后二种生物碱因量少尚待研究。
A total of six alkaloids were assigned to Aconitum koreanum R. Raymund. One of them is a known alkaloid, quebecine, and the other five are new alkaloids. It is temporarily called Guanfujiasu C_(24)H_(31)O_6N, B_C_(22)H_(29). O_5N, C_(22)H_(33)O_2N, C_(24)H_(35)O_3N, and C_(29)H_(43)O_7N. Guancificin is an acetate ketone that is attached to the B block. The formulas for Guansu A, B, and C were determined as: C_(19)H_(20)(OH)_2(CH_3COO)_2(CH_3)(:N·), C_(19)H_(20) (OH)_3(CH_3COO)(CH_3)(:N·), C_(19)H_(23)(OH)_2(CH_3)(N_C_2H_5). The latter two kinds of alkaloids need to be studied due to their small amount.
