麦角生物碱

以后利用麦角新碱能与氯仿形成复合结晶，却又难溶于氯仿的特性，可以使麦角新碱与其他麦角生物碱分离。

Ergometrine can be separated from the other ergot alkaloids with chloroform in which the former is insoluble as solvated crystals .

该菌种在小麦种子培养基上培养以后，除麦角新碱外，根据薄层层离鉴定结果证明还产生三种麦角生物碱。

By thin layer chromatography , it has been shown that this strain , cultured on wheat seed medium , was able to produce three other ergot alkaloids besides ergometrine .

其病因与妊娠期凝血功能异常、分娩中使用缩宫素及麦角生物碱，并与遗传、免疫及感染等因素有关。

The pathogeny is related to many factors such as abnormal blood coagulation function in gestation period , using oxytocin and ergot in labor , heredity , immunity , infection and etc.

麦角生物碱的层离研究Ⅰ.我国野生麦角的成分鉴定及麦角新碱的定量本文研究了应用无粘合剂氧化铝薄层层离和光电比色相结合的方法，测定麦角中三种主要生物碱的含量。

CHROMATOGRAPHY OF ERGOT ALKALOIDS ⅰ . IDENTIFICATION OF ERGOT ALKALOIDS AND DETERMINATION OF ERGOMETRINE CONTENT IN CHINESE ERGOTS Application of the thin layer chromatographic method to the determination of ergometrine , ergotamine and ergotoxine in ergot has been studied .

为了利用麦角新碱生产过程中母液里的其他麦角生物碱，并为进一步研究生物合成机制提供资料，必须先对母液中所含麦角生物碱进行分离和鉴定。

In order to fully utilise the alkaloids in the mother liquor , obtained during the production of ergometrine , and to gain information on the mechanism of biosynthesis , it was necessary to isolate and identify these ergot alkaloids .
