Seven diterpenoid alkaloids were isolated from Aconitum vilmorinianum var. patentipilum W. T. Wang. Their structures were determined as franchetine(Ⅰ), indaconitine(Ⅱ), yunaconitine(Ⅲ), talatisamine(Ⅳ), chasmaconitine(Ⅴ), crassicauline A (Ⅵ), and bikhaconine(Ⅶ). Last one has not been previously found in nature.  相似文献

From the roots of Aconitum nagarum var. lasiandrum W. T. Wang, seven diterpe- noid alkaloids were isolated and determined as follows: denudatine of atisine-type (7), songorine and songoramine of veatchine-type (1 and 12), virescenine of lycoctonine-type (13), neoline, 14-acetylneoline and fiavaconitine of aconitine-type (2, 3 and 8). A. nagarum var. lasiandrum W. T. Wang is a typical species of Ser. Bullatifolia which contained four types diterpenoid alkaloids. On the basis of distribution of diterpenoid alkaloids, phytogenesis add morphological evolution of Chinese species of genus Aconitum, probably Chinese species of genus Aconitum modernly advanced and divided from this serics.  相似文献

Four diterpenoid alkaloids were isolated by means of column chromatography and preparative HPLC from the roots of Aconitum leucostomum Worosch. Their structures were determined from the spectral data. One of them was found to be a new compound named leucostine ( Ⅱ ). The other three are known alkaloids, leuconine ( Ⅰ ), dehydroacosanine ( Ⅲ ) and sepaconitine (IV).  相似文献

深裂黄草乌二萜生物碱研究   总被引:3,自引:0,他引:3  
深裂黄草乌(Aconitum vilmorinianum var.altifidum W. T.Wang)又名西南乌头、紫乌头、藤乌,主要分布于云南东北部、贵州西部和四川西部(泸定、天全)海拔2800m的山地。块根可祛风散寒、除湿止痛,民间也用于解乌头中毒。其化学成分未见报道。本文从深裂黄草乌全草中分离鉴定了3个二萜生物碱,一个为C-19骨架类型,两个为C-20骨架类型。其中一个为新化合物,是C-20骨架类型二萜生物碱,命名为深裂黄草乌碱vilmorinianine(Ⅰ),另两个化合物是denudatine(Ⅱ)和deoxyaconitine(Ⅲ),均首次从该植物中得到。  相似文献

Three new aconitine-type C19-diterpenoid alkaloids, richardsonines A-C (1–3), were isolated from the roots of Aconitum richardsonianum Lauener, together with seventeen known compounds (4–20). Their structures were elucidated by extensive spectroscopic analysis, and the absolute stereochemistry of 1 was confirmed by X-ray crystallography. Compounds 2, 5, 8 and 9 were rare C19-diterpenoid alkaloids bearing an OH group at C-16. Isolated compounds were evaluated for inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated neuroinflammatory responses in BV-2 microglial cells. Compounds 3 and 7 showed weak antineuroinflammatory effects with inhibition rates of 35.32 ± 2.29% and 39.94 ± 2.50%, respectively, at a concentration of 100 µM.  相似文献
