Problems solved by technology

Although there are reports on the determination of α-linolenic acid in olive oil, it is difficult to accurately reflect the quality of olive oil by only controlling one component in olive oil
Other conventional detection methods also do not provide multi-component rapid identification and absolute content detection of unsaturated active ingredients oleic acid, linoleic acid and α-linolenic acid in olive oil

Embodiment Construction

[0027] Identification of olive oil: Take 70mg of olive oil, put it in a 5ml volumetric flask, add 1ml of 0.5mol / L potassium hydroxide methanol solution, heat in a water bath at 60°C for 30 minutes, let it cool, add 1ml of 11% boron trifluoride methanol solution , heated in a water bath at 60°C for 15 minutes, let cool, add 1ml of n-hexane, shake well, add saturated aqueous sodium chloride solution, bring the n-hexane layer to the neck of the bottle, and take the n-hexane layer as the test solution. Separately take about 20 mg each of oleic acid, linoleic acid, and α-linolenic acid reference substances, put them in 5 ml volumetric flasks respectively, add 1 ml of 11% boron trifluoride methanol solution, heat in a 60°C water bath for 15 minutes, let cool, Add 1ml of n-hexane each, shake fully, add saturated aqueous sodium chloride solution, bring the n-hexane layer to the neck of the bottle, and take the n-hexane layer as the reference solution. According to the test of gas chro...

Abstract

The invention discloses a quality control method for extracting unsaturated fatty acid by using olives. The method is a method for simultaneously identifying and determining the content of oleic acid,linoleic acid and alpha-linolenic acid in olive oil through a gas chromatography. The method comprises the following steps of 1, identification of the oleic acid, the linoleic acid and the alpha-linolenic acid in the olive oil by the gas chromatography, including chromatographic condition and system suitability tests, reference substance solution preparation, test solution preparation and determination; 2, determination of the content of the oleic acid, the linoleic acid and the alpha-linolenic acid in the olive oil by the gas chromatography, including chromatographic condition and system suitability tests, preparation of an internal standard solution, determination of a calibration factor, preparation of a test solution and determination. It is verified by an analytical method that the precision, reproducibility, recovery rate and stability are in line with the requirements of a Chinese Pharmacopoeia 2005 appendix 'Guidelines for the Validation of Chinese Medicine Quality Standard Analysis Methods'.

Description

technical field [0001] The invention relates to a quality control method for extracting unsaturated fatty acids from olives. Background technique [0002] This product is unsaturated fatty acid extracted from dried mature olive seeds by pressing or solvent extraction. After research, it was found that the main components of olive oil are oleic acid, linoleic acid, and α-linolenic acid. In terms of quality control, no one has identified and assayed the three at the same time. Although there are reports on the determination of α-linolenic acid in olive oil, it is difficult to accurately reflect the quality of olive oil by only controlling one component in olive oil. Other conventional detection methods also do not provide multi-component rapid identification and absolute content detection of unsaturated effective components oleic acid, linoleic acid and α-linolenic acid in olive oil. Contents of the invention [0003] The object of the invention is to provide a quality co...
