Studies on the Essential Oil of Green Tea. I. : Isolation of Dihydroactinidiolide and p-Vinylphenol

Abstract

Numerous compounds have been identified in the essential oil of green tea but in the present series of experiments, several unknown components were isolated from the high-boiling fraction of the essential oil of green tea by the use of gas, column, and thin-layer chromatography. Two of these components were identified as dihydroactinidiolide and p-vinylphenol, obtained earlier from the Actinidia polygama and black tea. The identification was based on infrared, ultraviolet, mass, and nuclear magnetic resonance spectral data.
