A Review of Methods for the Chemical Analysis of Rotenone-Bearing Plants (Classic Reprint)

Excerpt from A Review of Methods for the Chemical Analysis of Rotenone-Bearing Plants The Puerto Rico Experiment Station (128) recently reported that the already difficult problem of sampling baled derris root was further com plicated by the variation in rotenone and total-extract content of roots of the same diameter found in work at this station. It was suggested that a representative sample of the baled product could be obtained by using a small tube with a rotary cutter at the sampling end. Such a tool would make it possible to take a fairly large number of small samples and thus remove from the bale the minimum amount of root material required for a reliable analysis.
