Structures of condelphine, isotalatizidine, and talatizidine

Structure of hetisinone

“…which also proved to be a dehydrohetisine and which was tentatively assigned the same structure as hetisinone, mainly on the basis of the failure to observe the "anomalous" ultraviolet and infrared spectral features that would have been anticipated, had the alkaloid possessed either of the alternative structures (3) or (4). 4 We have now compared the semisynthetic and …”

New norditerpenoid alkaloids from Aconitum vilmorinianum Komarov

“…Thus, seven known alkaloids were isolated for the first time from A. vilmorinianum, and these were identified to be N-deethyl-N-19-didehydrosachaconitine (5) [11], pengshenine B (6) [12], 8-O-methyltalatisamine (7) [9], 8-O-methylsachaconitine (8) [13], geniculatine C (9) [14], acoforesticine (10) [15], and austroconitine (11) [16]. The other seven alkaloids were determined to be talatisamine (12) [17], isotalatizidine (13) [18], vilmorrianine D (14) [4], vilmorrianine B (15) [4], vilmorrianine A (16) [3], yunaconitine (17) [19], and vilmorrianine C (18) [3]. Meanwhile, it is noticed that aminoalcohol alkaloids talatisamine (12) and vilmorrianine D (14), and diester alkaloids vilmorrianine A (16), yunaconitine (17), and vilmorrianine C (18) were the main constituents in the roots of this medicinal plant.…”

“…The goodness of fit on F 2 was 1.070. Flack parameter = 0.05 (18). The Hooft parameter is 0.08 (7) The crystal data of compound 4: C 24 H 37 NO 6 .…”

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.…”
