| 摘 要： | Experiment on ultrasound- associated extraction of seed oil of Korean pine (Pinus koraiensis) was conducted in Northeast Forestry University, Harbin, China. The factors affecting extraction yield, such as ultrasonic frequency, extracting temperature, extracting time and the ratio of material to liquid (ratio of Korean pine seed to absolute alcohol), were analyzed under specific condition and the optimal extracting parameters were obtained as the ultrasonic frequency 32 000 Hz, the extracting temperature 80℃, the extracting time 50 rain, and the ratio of material to liquid 1: 30. The study demonstrates that ultrasound is a reliable and great efficiency tool for the fast extraction of Korean pine seed oil。

| Abstract: | Experiment on ultrasound-associated extraction of seed oil of Korean pine (Pinus koraiensis) was conducted in Northeast Forestry University, Harbin, China. The factors affecting extraction yield, such as ultrasonic
frequency, extracting temperature, extracting time and the ratio of material to liquid (ratio of Korean pine seed to absolute
alcohol), were analyzed under specific condition and the optimal extracting parameters were obtained as the ultrasonic frequency
32 000 Hz, the extracting temperature 80°C, the extracting time 50 min, and the ratio of material to liquid 1: 30. The study
demonstrates that ultrasound is a reliable and great efficiency tool for the fast extraction of Korean pine seed oil.
