Progress in Essential Oils: Long Pepper Oil

The present article is a survey of literature evaluating the constituents of Piper longum L., or long pepper, fruit oil. In one case, early researchers found the oil was devoid of monoterpene compounds and rich in sesquiterpenes, with b-caryophyllene being the major hydrocarbon. Lawrence (1978) and others also examined the composition of P. longum, the findings from which are discussed here.

Water-Soluble Fractions of the Essential Oils

Due to the different solubilities, various essential oil components are disproportionately postitioned into the aqueous phase and, hence, the variable polar components are either reduced or lost. Because of this phenomenon, relatively soluble minor components of the oil can escape completely resulting in an unbalanced odor and flavor profile when compared with that of the original plant. Therefore, the water soluble fraction is of importance to both the quantitative and qualitative outcome of the essential oil production.
