In this study, an efficient and green acidic pH based microwave-assisted aqueous extraction (MAAE) of seed oil extraction from yellow horn (Xanthoceras sorbifolia Bunge.) was investigated. It was observed that oil extraction yield increased at weak acidic condition, and the pH effects on the oil extraction process were illustrated. Meanwhile, the operating parameters were optimized using central composite design (CCD) combined with response surface methodology (RSM). From the economic perspective, the selected operating parameters were: pH 5, microwave power 500W. stirring rate 300 rpm, extraction temperature 70 degrees C, liquid to solid ratio 5.2:1 and extraction time 52 min. The physicochemical properties were determined to evaluate the quality of seed oil. The chemical composition of extracted seed oil was analyzed by GC-MS. This novel extraction technique provided high throughput and high quality oil.
