A new, rapid, simple, and sensitive calorimetric method for the estimation of resorcinol in microgram amounts is described. Rothera's test (1) has been routinely used to identify the presence of active -CH,-CO-CH,-groups in various biological samples. Thus, the formation of 3-oxoadipic acid from pr
The acid dye method for the estimation of certain alkaloids and other base compounds has been extended to atropine and other tropine alkaloids. This procedure is based on the observation that certain acidic dyes combine with many alkaloids to form saltlike compounds which are characterized by their
Futterman and Saslaw (1) have described a method for the estimation of retinal in the presence of retinyl acetate, retinol, retinoic acid, or p-carotene. The method depends upon formation of a colored derivative of retinal by reaction with thiobarbituric acid. This method has been successfully emplo
## Abstract A method is described for the estimation of alginic acid in seaseed samples, using the color reaction with carbazole and sulphuric acid, which can be applied on a micro scale, and is more rapid than the technique previously adopted.
