摘    要:从直缘乌头(Aconitum transsectum Diels.)根中分离得到4个新的乌头碱型 C_(19)-二萜生物碱。由光谱法(IR, ~1H NMR, ~(13)C NMR, 2D-NMR, MS)确定其 结构为:8-O-乙基滇乌碱(8-O-ethylyunaconitine) (1)、去氮乙基查斯曼宁(N- deethyl chasmanine)(2)、直缘乌碱丁(transconitine D)(3)和直缘乌碱戊( transconitine E)(4)。

关 键 词:直缘乌头  二萜 P  生物碱  红外分光光度法  质子磁共振谱法  碳十三核磁共振谱法  二维核磁共振谱法  质谱法

Abstract:Four new C 19 - diterpenoid alkaloids, 8 O ethylyunaconitine (1), N deethyl chasmanine (2), transconitine D (3)and transconitine E (4), were isolated from the roots of Aconitum transsectum Diels. together with 11 known norditerpenoid alkaloids, yunaconitine, indaconitine, vilmorrianine A, vilmorrianine C, crasscualine A, geniconitine, chasmanine, 8 deacetylyunaconitine, talatisamine, 14 acetyltalatisamine and chasmaconitine. Their structures were assigned on the basis of spectral data (IR, 1H NMR, 13 C NMR, 2D NMR and MS).
Keywords:Aconitum transsectum   C 19 diterpenoid alkaloid   8 O ethylyunaconitine   N deethyl chasmanine   transconitine D   transconitine E
