Embodiment 1

[0014] Add safflower herbs to CO 2 In the supercritical extraction tank, the extraction pressure is 25 MPa, the extraction temperature is 40° C., and the extraction time is 3 hours. The extract is filtered and separated to obtain safflower oil.

Embodiment 2

[0016] The safflower oil prepared in Example 1 and the safflower oil prepared by distillation were analyzed and identified by gas chromatography, and the main compounds were analyzed by mass spectrometry.

[0017] GC-MS conditions: 30m×0.25mm×0.25μm phenyl polysiloxane capillary column; column temperature 100°C, keep for 5min, raise temperature to 280°C at 5°C / min, keep for 30min, inlet temperature 280°C; helium 0.96 ml / min; safflower oil was dissolved in ether, and the injection volume was 0.5 μL.

[0018] Mass spectrometry conditions: ion source and transfer line temperature are 200°C and 260°C respectively, ionization mode is EI, ionization voltage is 70eV, ionization current is 0.22A, ion source pressure is 2.67×10 -5 Pa, the scan mass range is 10-600amu.

[0019] The yield of safflower oil obtained by steam distillation is 0.24%, wherein the higher content is eucalyptol (5.6%), milk mushroom aldehyde (15.7%), humulene-(Vl) (16.2%) %), eicosanic acid (5.4%), squalene (4....

Embodiment 3

[0021] Example 3 Using the safflower oil prepared in Example 1 as a raw material to prepare soft capsules of Xinnaoqing composition

[0022] Recipe: safflower oil 390g

[0023] borneol 3g

[0024] Vitamin E 17g

[0025] Vitamin B 6 5g

[0026] Take 130g of refined safflower oil, add borneol and vitamin B6, mix well, grind, add vitamin E and the remaining refined safflower oil, stir well, pass through a 100-mesh sieve, press into soft capsules, shape, wash the pills, and dry.

Abstract

The invention discloses a method for extracting safflower oil, which comprises the following steps: adding a medicinal material safflower in a CO2 supercritical extracting tank, wherein the extraction pressure is 20-40MPa, the extraction temperature is 35-45 DEG C and the extraction time is 1.5-3.5 hours, filtering an extract and separating to obtain the safflower oil. According to the invention, the damage of water vapor distillation method with high temperature on the easily oxidized components with unstable moisture and heat can be overcome, the defects of low oil yield by a pressing method and solvent residue generated by a solvent extraction method can be overcome, thereby the safflower oil with better quality can be obtained.

Description

technical field [0001] The invention relates to a method for extracting and preparing Chinese medicinal materials, in particular to a method for extracting safflower oil. Background technique [0002] Xinnaoqing Soft Capsule is based on safflower oil extracted from safflower, a traditional traditional Chinese medicine for promoting blood circulation and removing blood stasis, supplemented with fragrant borneol, vitamin E and vitamin B 6 Composition of traditional Chinese and Western medicine compound preparations based on traditional Chinese medicine. Safflower oil contains a variety of essential unsaturated fatty acids that the human body cannot synthesize by itself. It can not only reduce cholesterol, but also combine with cholesterol, reduce the deposition of cholesterol on the blood vessel wall, and effectively prevent and treat hypertension, hyperlipidemia, arterial Atherosclerosis, coronary heart disease, angina pectoris and sequelae of stroke and hemiplegia. Borneol...
