The structure of talatisamine

Hemsleyatine, a Novel C19-Diterpenoid Alkaloid with 8-Amino Group from Aconitum hemsleyanum

“…Part II was chromatographed on silica gel H column eluting with petroleum ether-acetone-diethylamine (90 : 10 : 1®50 : 50 : 1) to afford hemsleyatine (1) (290 mg), chasmanine (6) (84 mg), and talatisamine (7) (200 mg). The known alkaloids were identified on the basis of comparison of the 1 H-NMR data with reported values [11][12][13][14] and co-TLC behavior with the authentic samples.…”

Alkaloids fromFumaria parvifloraandF. kralikii*

“…It grows in fields, vineyards, on waste heaps, and in other places. From it were isolated the alkaloids (-)-adlumine, (+ )-bicuculine, coptisine, cryptopine, fumaramidine, fumaramine, fumaridine, fumariflorine, fumariline, fumaritine, (+)-ct-hydrastine, (+)-isoboldine, N-methylhydrasteine, noroxyhydrastinine, parfumidine, parfumine, parviflorifle, protopine, sanguinarine, and (-)-stylopine [3][4][5][6][7][8][9][10][11][12][13].…”

A New C19-Diterpenoid Alkaloid fromAconitum vilmorinianum

“…由于植物的 产地、气候等因素对其化学成分影响较大, 2008 年, 谭 宁 华 等 [3] 报 道 了 从 该 植 物 中 分 离 得 到 一 个 具 C(8)-C(9)-C(10)三元环体系的新骨架的 C 19 -二萜生物碱. 为了更好的开发利用我国乌头属植物的药用资源, 本课 题组对其进行更深入的系统研究, 从该植物中共分离得 到 20 个化合物(Scheme 1), 其中一个为新的 C 19 二萜生 物碱 epi-16β-hydroxycardiopetaline (1), 其余 19 个已知 化合物分别为: talatisamine (2) [4] , karakoline (3) [5] , sachaconitine (4) [6] , 14-O-veratroylneoline (5) [7] , vilmorrianine A (6) [8] , yunaconitine (7) [9] , condelphine (8) [10] , 14-acetyl-sachaconitine (9) [11] , indaconitine (10) [12] , 14-acetylkarakoline (11) [13] , 14-acetyltalatizamine (12) [14] , cammaconine (13) [15] , isotalatizidine (14) [16] , 8-deacetylyunaconitine (15) [17] , 16β-hydroxycardiopetaline (16) [18] , pseudaconine (17) [19] , columbianine (18), denudatine (19) [20] , panicutine (20) [21] . 新 化 合 物 的 结 构 应 用 HRESIMS, 1D-和 2D-NMR, 单晶 X 射线衍射等方法予 以确证.…”
