The extraction of oil from citronella has been done by different processes such as fractional distillation, steam distillation and hydro-distillation (Clevenger¡¯s apparatus) and through supercritical fluid equipments.
How to extract essential oil from Java citronella?
Three methods of essential oil extraction from Java citronella have been studied. The first method deals with the manual and crude extraction of essential oils using three different organic solvents (S1: methanol, S2: n -hexane, S3: petroleum ether) from dry powder (25 g) of citronella leaves.
How is Java citronella extracted?
Java citronella is cultivated in the fields for experimental extraction of essential oil through steam distillation at BIT Mesra. The leaves are cut and dried for 2¨C3 days till brittle. Approximately 1,000 kg of leaves (biomass) are steam distilled to yield citronella oil. A small volume were taken for the further analysis (Fig. 1 a, b, c).
Does US-Mahd extract citronella oil?
This study evaluates the performance of US-MAHD in the extraction of citronella oil from the citronella plant. Extraction is conducted for 90 min at various solvent-plant ratios (v/m) (10:1, 12:1, 14:1), ultrasonic bath temperature (30 °C, 40 °C, 50 °C), and power of microwave oven (150 W, 300 W, 450 W).
