Abstract
The photochemical degradation of lemon and orange oil and their equivalent amounts of ß-cyclodextrin (CD) complexes were investigated by 6LC. After irradiation intact menadione (or menadiol) was analysed by a colorimetric determination in its α-, ß- and γ-CD complexes. It was noted that the photolysis products p-cymene in lemon oil or carvone in orange oil increased with prolonged irradiation while some labile compounds decreased. These photodegradations of essential oils were inhibited by ß-CD complexation. Menadione decomposition was retarded by ß- and γ-CD complexation and the photodimerisation was stopped by α-CD complexation.
