A method for quantitative determination of four chrysanthemic acid isomers was also established.

Mixed racemic chrysanthemic acid was converted into the dl_trans form by stirring it in a solution of AlBr 3 in dioxane, with yield w 96%.

This paper reported the changes of IAA oxidase activities during potassium and chrysanthemic acid-induced rooting and the effect of Na3 VO4, the relatively specific inhibitor for plasma membrane H - pumping ATPase, on potassium and chrysanthemic acid-induced rooting in excised cucumber cotyledons.

Syntheses of pyrethric acid and its esters of 2(3)-fluoro-4-methoxymethylbenzyl and 2(3)-fluoro- 4-methylbenzyl alcohols were reported.

Preparation of cichoric acid by adsorption separation of macroporous resin;

Isolation and purification of cichoric acid from extracts of Echinacea purpurea by polyamide column chromatography;

Determination of cichoric acid in Enchinacea purpurea and its preparation by HPLC;

In order to make synthesis L1R-cis-permethrinic acid easier and safer, we prepared sodium tert-butoxide by an alcohol exchange reaction using tert-butyl alcohol and sodium methoxide, followed by reaction with methyl 3, 3-dimethyl-4, 6,6, 6-tetrachlorocaproate to produce cis-rich methyl permethrinate which was then hydrolyzed to perme-thrinic acid.
