Method for determination of lysergic acid isomers using liquid chromatography: Method for determination of lysergic acid isomers using liquid chromatography. Benes, Karel; Pavelek, Zdenek (Czech. ). Czech. CS 270042 B1 12 Feb 1991,3 pp. (Czechoslovakia). CODEN: CZXXA9. 5516-88-1 and 478-95-5 are cas registry numbers. These chemicals are also mentioned in this article. CLASS: ICM: G01N030-02. APPLICATION: CS 88-3451 23 May 1988. DOCUMENT TYPE: Patent CA Section: 80 (Organic Analytical Chemistry) Section cross-reference(s): 26 The isomers, namely lysergic acid, isolyzergic acid, and paspalic acid, are detd. by liq. chromatog. in an amine column by elution of mobile phases. The mobile phase comprises MeOH or a mixt. of MeOH and acetonitrile or THF in a vol. ratio from to 1:4, pH buffers AcONa 0-0.1M and AcOH 0-0.5M, and optionally ￡10 vol.% H2O. The isomers were detd. by comparing the areas under the peaks of each acid. .
