Embodiment 1

[0006] Example 1: Application C 14 Determination method, to determine whether a sample of soy isoflavones in health products is a pure natural product, first measure the known pure natural soy isoflavones, and determine its C per gram of carbon per minute 14 The decay number is 13.094dpm / gc; then measure soy isoflavones known to be purely synthetically produced, and determine their C per gram of carbon per minute 14 The decay number is 0.11dpm / gc, and 13.094 is far greater than 0.11. The judgment result: the soy isoflavones in the test sample are not pure natural, and its carbon source is "dead carbon" earlier than 37,000 years ago. The test result is completely consistent with the reality .

Embodiment 2

[0007] Example 2: Application C 14 Assay method, another soy isoflavone sample is tested again, it is known to contain 40% soy isoflavones and 60% pure natural soy isoflavones produced by synthetic method, know the pure natural soy isoflavones from embodiment 1, C per gram of carbon per minute 14 The decay number is 13.094dpm / gc; the soy isoflavone sample was measured, and its decay number per gram of carbon per minute was determined to be 7.921dpm / gc. The result confirmed that the soy isoflavones in the test sample were not pure natural. Obviously, wherein the pure natural ingredients are 7.921÷13.094×100%=60%, and the synthetic ingredients are 40%.

Abstract

The invention relates to a method for determining whether a medicine is pure natural or not. The characteristics are that testing method of is adopted. First, C14 contained in unit weight of carbon in known pure natural medicine is measured, supposed as A. Then, C14 contained in unit weight of carbon in medicine to be determined is measured, supposed as B. If value A is equal to value B or they are closed each other, then the latter is a pure natural medicine. If value A is far larger than value B, then the latter is not a pure natural medicine, and the ratio of synthetical material and natural material can be calculated out. The invented method can be used to determine whether a material is pure natural or not such as Chinese medicine, Wester medicine, food for additive health care food and flavoring.

Description

technical field [0001] The invention relates to a method for judging pure natural products such as pure natural traditional Chinese medicine, western medicine, food, food additives, health care products and condiments. Background technique [0002] Many suppliers and sellers of all-natural products claim that the products they sell are all-natural products, whose raw materials are extracted directly from the plant or animal body of today's plants, so as to "prove" that the product is all-natural, which is always true. False is hard to tell. The current general judgment method is to use a gas chromatograph or a high-pressure liquid chromatograph to measure the spectrum of the tested product, and then compare it with the standard spectrum of a standard pure natural product. Reliable reference material, it cannot be completely determined that the tested product is directly extracted from the plant or animal body. Contents of the invention [0003] Products extracted from to...
