A study was performed on kumquat peel extracted by different methods: hydrodistillation, solvent and supercritical carbon dioxide (SC-CO2) extractions at a density of 281 g/dm3 (80 bar and 40°C of temperature) and 875 g/dm3 (250 bar and 40°C temperature). A total of 24 compounds were quantified: 8 monoterpene hydrocarbons, 6 terpene alcohols, 1 terpene aldehyde, 1 ketones terpene, 4 terpene esters, 4 sesquiterpene hydrocarbons. The amount of the major compound, limonene, in the essential oil obtained from Kumquat peel is high (96 %), followed myrcene (1.6-1.7 %) and the germacrene-D (0.9-1.4 %). The three studied extractions (hydrodistillate, solvent and SC-CO2) present a similar composition regarding to limonene, myrcene and germacrene-D.

Abstract

A study was performed on kumquat peel extracted by different methods: hydrodistillation, solvent and supercritical carbon dioxide (SC-CO2) extractions at a density of 281 g/dm3 (80 bar and 40°C of temperature) and 875 g/dm3 (250 bar and 40°C temperature). A total of 24 compounds were quantified: 8 monoterpene hydrocarbons, 6 terpene alcohols, 1 terpene aldehyde, 1 ketones terpene, 4 terpene esters, 4 sesquiterpene hydrocarbons. The amount of the major compound, limonene, in the essential oil obtained from Kumquat peel is high (96 %), followed myrcene (1.6-1.7 %) and the germacrene-D (0.9-1.4 %). The three studied extractions (hydrodistillate, solvent and SC-CO2) present a similar composition regarding to limonene, myrcene and germacrene-D.
