AI Technical Summary

Technical Problem

The prior art lacks standard samples of cannabinoids in edible oils, resulting in increased deviations in the detection results and difficulty in quality control, and the preparation and dilution method cannot meet different limit requirements and separate assignments of multiple cannabinoids.

Method used

Through the addition method, the cannabinoids and edible oil are deeply combined with the help of the medium solvents ethyl acetate and cyclohexane. Ultrasonic stirring and vacuum drying technology were used to prepare a standard cannabinoid sample of expected values, and the content and proportion of each cannabinoid can be adjusted.

Benefits of technology

The preparation of standard samples of cannabinoids in edible oils has been realized, the comparability of test data between laboratories has been improved, the quality control and traceability of test results has been ensured, and the limited quantity requirements of different countries and laboratories have been met.

Abstract

The present invention discloses a method for preparing a standard sample of edible oil-based cannabinoids, comprising the following steps: (1) using ethyl acetate and cyclohexane solvents with a volume ratio of 1:1 to dissolve a cannabinoid standard solution and ultrasonically mix to obtain a cannabinoid standard; (2) adding the cannabinoid standard obtained in step (1) to edible oil, and ultrasonically mixing, and finally placing it in a vacuum drying oven, and operating it at 40° C. and a vacuum degree of 20 Mpa for 1 hour to obtain an edible oil-based cannabinoid standard sample. The present invention uses an addition method to convert cannabinoids into a medium and then combine them with edible oil, thereby obtaining cannabinoids of expected values, and can adjust the content and proportion of each cannabinoid, and can also combine the matrix characteristics of the edible oil to prepare standard samples of cannabinoids in multiple edible oils. At the same time, the cannabinoids added by the method are certified standard substances, thereby providing a good basis for the traceability of the prepared samples.
