Abstract: Present study was aimed to optimize the parameters viz., particle size, extraction time and pre-heating temperature for soxhlet extraction of garden cress oil (GCO). Garden cress seeds were reduced to three size ranges (0.600, 0.425 and 0.300 mm) and heated in hot air oven for 20, 30 and 40 min at 100 °C. Extraction was carried out in soxhlet using petroleum ether for 2, 4 and 6 h. Effect of these parameters on yield and peroxide value of GCO was investigated. Experiment was designed according to face centered central composite design using design expert 10.0.0 software. Optimization of process parameters was done by response surface methodology. Results showed that, oil yield was higher from the smaller size of particles and increased with increasing heating time and extraction time. Peroxide value was also higher for oil extracted from the smaller size particles and increased with increasing heating and extraction time. Yield was ranged between 17.14 to 24.21% whereas PV ranged between 2.18 to 3.92 meq.kg-1. Optimized condition was obtained for 0.425 mm size, heating for 30 min and extraction for 4 h giving yield 23.1% and PV 2.513 meq.kg-1.
