Problems solved by technology

Although it is reported that the content of α-linolenic acid in pepper oil is determined, it only controls one component in pepper oil and it is difficult to accurately reflect the quality of pepper 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 pepper oil

Embodiment Construction

[0027] Identification of pepper oil: take 70mg of pepper 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 cool, add 11% boron trifluoride methanol Heat 1ml of the solution in a water bath at 60°C for 15 minutes, let it 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 ch...

Abstract

This invention relates to a zanthoxylum oil quality control method, which comprises the following steps: 1. taking test for chromatographic condition and the E&ST, preparing solution of reference substance and sample solution, and identifying the oleic acid, linoleic acid and alpha-linolenic acid by GC; 2. similarly, taking E&ST, preparing internal standard solution and sample solution, determining the correction factor, and determining the content for former acid. The result shows all of the precision, repeatability, recovery ratio and stability of This invention accords with national guiding principle.

Description

Technical field: [0001] The invention relates to a quality control method, in particular to a quality control method of peppercorn oil. Background technique: [0002] This product is the refined unsaturated fatty acid extracted from the dried mature seeds of Zanthoxylum bungeanum Maxim. of Rutaceae Zanthoxylum plant by pressing or solvent extraction. The research found that the main components of pepper 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 it has been reported to measure the content of α-linolenic acid in pepper oil, it is difficult to accurately reflect the quality of pepper oil by controlling only one component in pepper oil. Other conventional detection methods also did not provide multi-component rapid identification and absolute content detection of the unsaturated active ingredients oleic acid, linoleic acid and α-linolenic acid in pepper oil. Inve...
