Embodiment 1

[0037] Schisandra chinensis is a medicinal material native to Liaolin. Six soil samples were taken from different planting areas of the origin of Schisandra chinensis, and the corresponding 6 authentic medicinal materials of Schisandra chinensis were taken as samples. Then the non-authentic medicinal material of Schisandra chinensis was cultivated with the soil sample from the non-origin area, and 6 samples of the soil sample from the non-origin area and the non-authentic medicinal material sample of Schisandra chinensis were taken. Detect the trace element content in above-mentioned four kinds of samples and get average value (n=6), test result is shown in the following table (unit: mg / kg):

[0038]

[0039] It can be seen that the content of two trace elements Cd and Mn in Schisandra chinensis has a good correlation with the content of Cd and Mn in the soil where it was cultivated, while trace elements such as Ba, Cu, Cr, Mn, Ni and Zn content is relatively constant. The...

Embodiment 2

[0041] Huangling is a medicinal material native to the central part of Inner Mongolia. Six soil samples were taken from different planting areas in the origin of Huangling, and the corresponding 6 authentic medicinal materials of Huangling were taken as samples. Then the non-authentic medicinal materials of Huangling were cultivated with the soil samples from the non-origin, and 6 samples of the soil samples from the non-origin and 6 samples of the non-authentic medicinal materials of Huangling were taken. Detect the trace element content in above-mentioned four kinds of samples and get average value (n=6), test result is shown in the following table (unit: mg / kg):

[0042]

[0043]

[0044] It can be seen that the content of Cu, Ni and Zn in Huangling has a good correlation with the content of Cu, Ni and Zn in the soil where it was cultivated. The content ratio of Ni and Zn in the soil is basically the same. The contents of trace elements such as Ba, Cr and Mn are rela...

Embodiment 3

[0046] Phellodendron Phellodendri is a medicinal material native to Sichuan. Six soil samples were taken from different planting areas of Phellodendron Phellodendri, and corresponding 6 authentic medicinal materials of Phellodendron Phellodendri were taken as samples. Then the non-authentic medicinal materials of Phellodendron Phellodendron were cultivated with soil samples from non-origin areas, and 6 samples of soil samples from non-origin areas and non-authentic medicinal materials of Phellodendron Phellodendri were taken. Detect the trace element content in above-mentioned four kinds of samples and get average value (n=6), test result is shown in the following table (unit: mg / kg):

[0047]

[0048] It can be seen that the Ba content in Phellodendron cortex has a good correlation with the Ba content in the soil where it was cultivated, while the contents of other trace elements are relatively fixed. Therefore, it can be determined that the identification standard of auth...

Abstract

The invention belongs to the technical field of discrimination of production areas of crude drugs, and concretely relates to a method for discriminating and identifying a geo-authentic crude drug. Existing technologies for discriminating and identifying geo-authentic crude drugs by discriminating the appearance, the smell and the factory label have a problem of restriction. The method in the invention comprises the following steps: [1] testing the content of trace elements in a soil sample from the source area of the geo-authentic crude drug and the content of the trace element in a geo-authentic crude drug sample; [2] testing the content of the trace elements in a soil sample for cultivating a non-geo-authentic crude drug and the content of the trace elements in the non-geo-authentic crude drug; [3] determining the discriminating standards of for the corresponding variety of the geo-authentic crude drugs tested in step [1] and step [2], wherein the discriminating standards are the content of trace elements or the content ratio of two trace elements; and [4] testing the content of the trace elements in a crude drug sample to be tested, and comparing obtained data with the data of the discriminating standards to judge whether the crude drug sample to be tested is a geo-authentic crude drug or not. The method is suitable for discriminating the producing area of plants.

Description

technical field [0001] The invention belongs to the technical field of identifying the origin of medicinal materials, and in particular relates to a method for identifying and marking authentic medicinal materials. Background technique [0002] Authentic medicinal materials, also known as authentic medicinal materials, are synonymous with high-quality Chinese medicinal materials, which means that the medicinal materials have excellent efficacy.
