[0022] Example 1:
[0023] (1) Take the zedoary turmeric oil prepared by Wenyujin, put it into the tower kettle of the vacuum precision distillation device, and heat it. The tower kettle temperature is controlled at 127~180℃, the column height is 1.50 meters, the column inner diameter is 40mm, and the number of plates: ≥ 40.1, the reflux ratio is 6:1, the packing is rolled with 4mm×4mm stainless steel mesh, and the vacuum degree is below 500 Pa for internal reflux. The fractions with column temperature in the range of 30~110℃ are collected and divided according to the order of temperature from low to high. For five fractions, keep the fourth fraction with a column temperature of 80.1~81.9℃, remove the first and second fractions, and combine the third and fifth fractions;
[0024] (2). The combined fractions of the third and fifth fractions in step (1) are rectified again according to the conditions of step (1), and the second, third, and third fractions are collected at the temper...

[0025] Example 2:
[0026] (1). Take the zedoary turmeric oil prepared by Wenyujin, put it into the tower kettle of the vacuum precision distillation device, and heat it. The tower kettle temperature is controlled at 130~180℃, the column height is 2.0 meters, the column inner diameter is 100mm, and the number of plates ≥ 40.1 , The reflux ratio is 10:1, the packing is rolled with 5mm×5mm stainless steel mesh, and the vacuum degree is below 500 Pa for internal reflux. The fractions with the column temperature in the range of 30-110℃ are collected and divided according to the order of temperature from low to high Five fractions, keep the fourth fraction whose column temperature is 83.1~88℃, remove the first and second fractions, and combine the third and fifth fractions;
[0027] (2). The combined fractions of the third and fifth fractions in step (1) are rectified again according to the conditions of step (1), and the second, third, and third fractions are collected at the temperat...

[0028] Example 3:
[0029] (1) Take the zedoary turmeric oil prepared by Wenyujin, put it into the tower kettle of the vacuum precision distillation device, and heat it. The temperature of the tower kettle is controlled at 170~230℃, the column height is 1.41 meters, the column inner diameter is 30mm, and the number of plates ≥ 40.1, the reflux ratio is 15:1, the packing is rolled with 3.1mm×3.1mm stainless steel mesh, the vacuum degree is below 1000 Pa for internal reflux, and the fractions with the column temperature in the range of 30~110℃ are collected and the temperature increases from low to high. Divide into five fractions in sequence, keep the fourth fraction with a column temperature of 94~100℃, remove the first and second fractions, and combine the third and fifth fractions;
[0030] (2). The combined fractions of the third and fifth fractions in step (1) are rectified again according to the conditions of step (1), and the second, third, and third fractions are collected ...
