SILVIA ROBU, AURELIA ROMILA, OLIMPIA DUMITRIU BUZIA, ADRIAN FLORIN SPAC, CAMELIA DIACONU, DANA TUTUNARU, ELENA LISA, AUREL NECHITA CONTRIBUTION TO THE OPTIMIZATION OF A GAS CHROMATOGRAPHIC METHOD BY QBD APPROACH USED FOR ANALYSIS OF ESSENTIAL OILS FROM SALVIA OFFICINALIS
Numerous articles on Salvia officinalis L. have been published regarding the composition of their essential oil. The considerable variation found may be due to the quality of the plant material as well as to the methods used for analysis. A simple GC-MS method was developed and optimized in the QbD approach, for the determination of sage essential oils. The optimization of GC-MS analysis was performed using different mobile phase flows, injection volumes, split ratios and temperature programs. The optimized method proved to be simple and can be successfully applied for the determination of sage essential oils.
