✦ Synopsis

Eleven published and unpublished methods for extraction of chloride from plant tissue were compared, using a homogeneous sample of dried, ground maize leaves previously labelled with 36C1. The most effective method of extraction of CI-, estimated by liquid scintillation counting of 36C1, was with hot water. However, six other methods, including either cold water extraction, or dry-ashing at 500~ of plant material previously treated to give an alkaline pH, gave 36C1 values that were not statistically different from that obtained with hot water extraction. The lowest estimates of 36C1 content were obtained either by wet digestion in nitric/acetic acid or by dry-ashing following Mg(NO3) 2 treatment of the plant material.

## Abstract Metabolite analysis is recognized as an important facet of systems biology, however complete metabolome characterization has not been realized due to challenges in sample preparation, inherent instrumental limitations and the labor intensive task of data interpretation.

Acute and Chronic Toxicity of Veratrum V

Acute and Chronic Toxicity of Veratrum Viride††The Veratrum viride studied was the whole-powdered drug marketed by Irwin, Neisler & Co. under the name, Vertavis. The work reported herein was supported by a grant from this firm. The batch of powder used in these experiments was stated by the manufacturer to have been assayed biologically by the Craw method on Daphnia magna. One Craw unit of the material studied was stated to be 15.6mg. With regard to this assay, Mr. R. O. Craw has been so kind as to allow us to publish a brief explanation: A reference lot of Yerolrum oirid; powder was set-aside as a standard and a 10% w/v aqueous extract was made of this powder. The average median length of life in 50 assays of 1000 daphnia on immersion in the solution was determined to be 2.22 hours. The daphnia were considered dead when the heart was found to be in systolic standstill on microscopic examination. Succeeding lots of powder were assayed and their potency determined by relating the median length of life of daphnia to 2.22 hours, which is one unit. Twenty assays of 10 animals each were used on each lot of powder.‡‡The authors wish to thank Dr. J. F. A.,McManus of the Department of Pathology for a pathologic report on the tissues, and Mr. James Thomas and Mrs. Bobby E. Teague for technical assistance.
