EVALUATION OF VOLATILE OILS

 

 

Product from different manufacturers varies considerably, since it is inherently difficult to control all the factors that affect a plants chemical composition. Environmental conditions such as sunlight and rainfall, as well as manufacturing process can create substantial variability in essential oil quality. Various procedures are given for the evaluation of essential oils. Preliminary examinations like odour, taste, and colour. Physical measurements, which includes optical rotation, relative density, and refractive index. Chromatographic techniques are used to determine the proportions of individual components of certain oils. The ketone and aldehyde content of oils are determined by reaction with hydroxylamine hydrochloride (oxime formation) and titration of the liberated acid. The oil, which passes the above examinations, would be having good quality and therapeutic value.
