Various chemical measurements of toxicity including the red color value described by Jones (^), total chloroform extractives, and percent transmittance of acetone extracts suggested by Pagan and Loustalot (^, 7) were compared with the toxicological value (rotenone equivalent) of the roots dried in the sun, in the shade, and in the oven.

The red-color test gave the best chemical estimate of the toxicity of the samples, but it, too, has certain limitations due to the fact that the values obtained are not always in close agreement with the biological assay, as shown in table 1.

The report showed derris root to be generally superior to lonchocarpus root even when the rotenone content was equal, and additional chemical analyses were made in an attempt to trace the toxicity due to compounds other than roten one.
