Abstract
Abstract Oleoresin is a product obtained from extraction using organic solvents, which is a mixture of essential oils and resins. The extraction temperature affects the yield and the quality of oleoresin. This study aims to determine the effect of maceration extraction temperature (70, 75, and 80°C) on the yield, the citral content and the citral yield of lemongrass leaves oleoresin. Maceration extraction to obtain oleoresin from lemongrass leaves was carried out for 6 hours. HPLC analysis was performed to obtain the citral content in lemongrass leaves oleoresin, using a C18 column (15 cm x4.6 mm) with acetonitrile and water as mobile phases (70:30). The results showed that extraction temperature affects the yield of lemongrass leaves oleoresin, but does not affect the citral content and the citral yield. This means that if the targeted component of the oleoresin extraction is a citral component, then extraction is sufficient to be carried out at a temperature of 70°C with an extraction time of 6 hours.
