Comparative Investigations of the Essential Oil and Volatiles of Spearmint

The objective of this work is to identify the fragrance compounds of this oil and its SPME-headspace by means of gas chromatographic- spectroscopic (GC and GC/MS using different polar and chiral phases) and olfactoric methods (GC-sniffing technique and olfactory correlations) to find out the importance of each single constituent with their specific odor attributes, responsible for the characteristic and pleasant spearmint aroma for the first time.

Counter Current Deterpenation of Cold Pressed Sweet Orange Peel Oil

Volatile Constituents of Essential Oils Isolated from...

The essential oils isolated from different parts of Alpinia calcarata Rosc., (family: Zingiberaceae) growing in Hyderabad, south India, were analyzed by capillary GC and GC/MS. The oil yields were: flower 0.06%, leaf sheath 0.03%, stem 0.05% and root 0.18%. Sixty-two compounds accounting for 92.3-98.3% of the oils were identified.
