The optimal homogenate extraction process of Humulus scandens seed oil was explored.The effects of liquid-solid ratio, extraction voltage, extraction time and extraction times on the oil yield of Humulus scandens seed were investigated by response surface methodology based on single factor experiment. The results showed that the optimal extraction conditions were obtained as follows: extraction voltage 150 V, liquid-solid ratio 10∶?1, extraction time 135 s and extraction times once. Under these conditions, the oil yield of Humulus scandens seed was 9.50%. In comparison, the oil yield of Humulus scandens seed in Anhui province was the highest, followed by Jiangsu and Zhejiang, and Shandong was the lowest. Anhui province had the highest oil yield in Hefei, followed by Chizhou and Huangshan, and the lowest in Bozhou. |
