Alkaloids, GS-MS, Datura stramonium The alkaloid spectrum in roots, leaves and seeds of Datura stramonium L. was investigated by GC-MS. Twenty-nine tropane alkaloids are detected. Twelve of them are new constituents for the species and the two tropane esters 3-(3'-acetoxytropoyloxy)tropane (21) and 3-(2'-hydroxytropoyloxy)tropane (26) are described for the first time.  相似文献

曼陀罗种子休眠机理与破眠方法研究   总被引:6,自引:0,他引:6  
通过对曼陀罗种子生活力测定、发芽试验、吸水率测定及种子萌发抑制物研究,揭示曼陀罗种子休眠机理,并利用物理、化学法处理曼陀罗种子,以探寻打破曼陀罗种子休眠的最佳方法.结果表明:(1)新采收的曼陀罗种子为综合休眠,休眠原因包括:种皮障碍、缺少萌发所需激素以及种皮和种仁中存在萌发抑制物,其中种皮障碍是限制种子萌发的首要因素.(2)室温存储6个月可解除曼陀罗种子种仁的休眠,但种皮障碍始终是其种子萌发的限制因素.(3)机械摩擦、浓H2SO4处理和NaOH处理均可打破除曼陀罗种皮的休眠障碍,促进种子萌发,其中用10% NaOH处理90 min为破除曼陀罗种皮休眠障碍的最佳方法,且发芽率比对照提高了83%.  相似文献

Walker , Waldo S. (Grinnell College, Grinnell, Iowa.) The effects of mechanical stimulation and etiolation on the collenchyma of Datura stramonium. Amer. Jour. Bot. 47(9) : 717–724. Illus. 1960.–In an effort to determine the effect of mechanical stimulation on collenchyma tissue, plants of Datura stramonium L. were placed on a mechanical agitator and subjected to intensive shaking for 9 hr. per day for 40 days. Measurements indicated that such stimulation greatly increased the amount of wall thickening per cell, as observed in transverse section. Measurements also indicated that such stimulation may inhibit collenchyma cell elongation. A second group of Datura stramonium plants was placed in total darkness to determine the effect of such treatment on the quantity of wall thickening in the collenchyma tissue. Measurements indicated that when plants were placed in the dark for extended periods a great reduction of wall thickening resulted. It is suggested that reduction of wall material was due to its utilization as substrate for respiratory processes which occur in the plant under such extreme conditions. The composition and structure of the collenchyma cell walls are discussed.  相似文献

Summary Three sexual generations of the somatic hybrids from Datura innoxia+Datura stramonium (Datura straubii) and from Datura innoxia+Datura discolor (Datura hybrida) were investigated (Schieder, 1978). Self fertility of the somatic hybrids proved to be comparable to that of the parental plant species. The good fertility is attributed to the low number of quadrivalents formed in meiosis I. The growth rate of the somatic hybrids is superior to the parental plant species and also to the autotetraploid somatic hybrids of Datura innoxia. Datura innoxia is the species showing the best growth rate of all species used for the hybridization experiments. In addition, some irregularities in the sexual generations are described.Dedicated to my teacher, Prof. Dr. J. Straub, on the occasion of his 70th birthday.  相似文献

通过野外及走访调查,对西双版纳野生有毒植物资源进行了调查,同时对其科属分布、生活型组成、毒性、有毒部位进行了分析。结果显示,西双版纳野生有毒植物289种,隶属于79科214属,其中优势科集中在豆科、大戟科、天南星科、夹竹桃科、芸香科,优势属为大戟属和茄属;生活型以草本植物居多,占36.68%;有毒部位以全株或全草有毒为主,占37.37%;毒性以小毒植物占大多数,剧毒植物有5种,大毒植物有11种。通过走访调查了解到,商陆、钩吻、相思子、曼陀罗、洋金花、油桐、蓖麻等有毒植物种类在民间曾多次发生误食中毒甚至死亡事例,需要特别注意识别。今后应加强对常见有毒植物的辨识与防范科普宣传,同时加强对有毒植物的开发和应用研究。  相似文献

Purification of the lectin from Datura stramonium.   总被引:10,自引:3,他引:7       下载免费PDF全文
The lectin from Datura stramonium can be inhibited by oligomers of N-acetylglucosamine. This property was exploited to purify the lectin by affinity chromatography on Sepharosefetuin. The purified lectin is a glycoprotein in having subunits of 40 000 and 45 000 mol.wt.  相似文献

Tropine (tropan-3 alpha-ol) is an intermediate in the formation of hyoscyamine. An acyltransferase activity that can acetylate tropine using acetylcoenzyme A as cosubstrate has been found in transformed root cultures of Datura stramonium. A further acyltransferase activity that acetylates pseudotropine (tropan-3 beta-ol) with acetyl-coenzyme A is also present. These two activities can be partially resolved by anion-exchange chromatography, some fractions containing only the pseudotropine-utilizing activity. The basic properties of these two enzymes are reported and their roles in forming the observed alkaloid spectrum of D. stramonium roots discussed.  相似文献
