- Identification
Adulterations of St. John's Wort oil with the alkanna-derived dyestuff alkannin or azo dyestuffs can be detected by using the following analytical methods:
Mix 5 ml of St. John's Wort Oil with 10 ml of diethyl ether and distribute the mixture to 2 test tubes. Add 3 ml of hydrochloric acid to one of the samples and shake. If the aqueous phase develops a red color after a few minutes, the St. John's Wort oil has been adulterated with azo dyestuffs. Alkanna additives will not stain the hydrochloric acid layer. Unadulterated St. John's Wort oil will develop a light-green color.Add a few milliliters of 0.5 N alcoholic potassium hydroxide to the other sample. Alkanna
additives will cause a cornflower blue color. Oil mixtures will stain blue-green, olive-green to pale-green. Unadulterated St. John's Wort oil will develop a clear green color.
