Volatile compounds of grapefruit (Citrus Grandis (L.) Osbeck) peel essential oil by cold pressing and hydrodistillation methods

Abstract

Abstract The study of the essential oils (EOs) extraction with high medicinal properties is necessary to contribute to the use of natural compounds. By using cold pressing and hydrodistillation methods, the content of grapefruit peel (Citrus grandis (L.) Osbeck) EOs was extracted. The chemical components of EOs was determined by GC-MS method. Results have shown that 10-12 compounds were detected in the grapefruit peel EOs, which are mainly monoterpenes such as D-Limonene (71.21%-74.83% and γ-Terpinene (15.70%-17.68%). The findings from the present study demonstrated a new research direction on chemical composition of the grapefruit EO, thereby contributing to applications ofthe natural compounds with high medicinal properties from grapefruit.
