✦ Synopsis

Two procedures have been developed for the quantitative determination of arecoline hydrobromide in capsule preparations. In the colorimetric assay, the arecoline salt was converted to the base with aqueous sodium bicarbonate, extracted into chloroform, and reacted with methyl orange. The absorbance was determined at 527 mp. With the GLC method, the arecoline salt was converted to the base in a 5:100 triethylamine-chloroform solution and directly injected onto the column, using nicotine as the internal standard. The GLC method was found to be faster and more accurate.

Aroma concentrates of Ceylon black tea were prepared by two methods, (5) steam distillation and (2) adsorption on charcoal of the head-space vapor over a tea brew followed by elution with diethyl ether. The former method was superior to the latter, perhaps partly due to formation of artefacts on the
