From the leaves ofStrychnos icaja Baill. a further seven alkaloids have been isolated and their structures determined: 16-hydroxystrychnine (1e), 21,22-α-epoxy-4-hydroxy-3-methoxy-N-methyl-sec.-pseudostrychnine (5c), 21,22-α-epoxy-4-hydroxy-N-methyl-sec.-pseudostrychnine5a), 21,22-α-epoxy-2-methoxy-N-methyl-sec.-pseudostrychnine (5b), 21,22-α-epoxy-14-hydroxy-N-methyl-sec.-pseudostrychnine (6a), 21
从Strychnos icaja Baill的叶子。已分离出另外七个生物碱并确定了其结构:16-羟基金丝氨酸(1e),21,22-α-环氧-4-羟基-3-甲氧基-N-甲基-仲-伪金丝氨酸(5c),21,22 -α-环氧-4-羟基-N-甲基-仲假丝孢碱5a),21,22-α-环氧-2-甲氧基-N-甲基-仲-假丝孢碱(5b),21,22-α-环氧-14-羟基-N-甲基-仲假丝氨酸(6a),21,22-α-环氧-4,14-二羟基-N-甲基-仲-假丝氨酸(6b)和14-羟基-N -甲基-仲-伪孢子碱(7)。Jaminet的生物碱B'被证明是不纯的21,22-α-环氧-14-羟基-2,3-二甲氧基-N-甲基-仲-假丝孢碱(6c)。
