Embodiment 1

[0048] The thin layer detection method of plant extract in the detrogin includes the following steps:

[0049] 1) Preparation of the solution solution and sample solution

[0050] 1.1) Take a proper amount of white vague and yellowette, and dissolve the solution solution having a mass concentration of 1 mg / ml of ethanol, respectively, and numbered No. 1, No. 2;

[0051]1.2) Take a plant extract which does not contain a detrinant, add 10% white vague plant extract, add 10% yellowing plant extract each 100g to sealed test vessel, add 10 ml of mass concentration. It is 50% dissolved and ultrasonic treatment for 60 minutes. After removing the test container and then filtered to room temperature, then filtered with a microporous filter, collecting the filtrate as a sample solution, and numbered No. 3, No. 4, and 5;

[0052] 2) Thin layer

[0053] The substandent solution and the sample solution prepared in step 1), in order, separately in different positions of the same height on the...

Embodiment 2

[0070] The difference from Example 1 is:

[0071] In step 1.2), the number of white paste in the number 4 is 20%, and the amount of yellowette in the number 5 is 30%;

[0072] In step 2), the distance from the lower edge of the silica gel G is 1.5 cm;

[0073] In step 4), when the front edge of the expander is up to the edge of the silicone G thin laminate, the silica gel G thin layer plate is taken out when the origin is 10 cm.

[0074] Get the color map figure 2 The same judgment method as in Example 1 is used. figure 2 It can be concluded that the samples of the number 4 contain a white vague, and the content is greater than 10%; the samples of the number 5 contain a yellowette, and the content is greater than 10%; the determination result is consistent with the actual sample results.

Embodiment 3

[0076] The difference from Example 1 is:

[0077] In step 1.2), the amount of white paste in the number 4 is 5%, and the amount of yellowette in the number 5 is 5%; ultrasonic treatment for 30 minutes;

[0078] In step 5), the spray is sprayed with a mass concentration of 5% sulfate solution;

[0079] Get the color map image 3 The same judgment method as in Example 1 is used. image 3 It can be concluded that the sample of the number 4 contains white vague, and the content is less than 10%; the sample of the number 5 contains yellowette, and the content is less than 10%; the judgment result is consistent with the actual sample results.

[0080] The above Examples 1-Example 3 uses a verification method, a sample, and reverse verify the reliability of the method of the invention.

Abstract

The invention provides a thin-layer detection method for dextrin in plant extracts, which solves the problem that the type and approximate content of dextrin in plant extracts cannot be judged by using the existing dextrin detection method. The method comprises the following steps: 1) preparing a reference substance solution and a sample solution; 2) spotting on a thin layer; 3) preparing a developer; 4) developing; 5) developing color to form spots; 6) contrasting and identifying. This thin-layer detection method is low in cost, easy to operate, fast, and rich in map information. It has high sensitivity, strong specificity, obvious detection contrast to dextrin, intuitive results, easy identification and differentiation, and provides a solid foundation for ensuring the quality of plant extracts. reliable method of identification.

Description

Technical field [0001] The present invention belongs to the field of substance identification, and more particularly to a thin layer detection method of plant extract in debride. Background technique [0002] The starch will decompose and hydrolyze under heating, an acid or in the action of the amylogenic enzyme. The faults can be divided into three categories of production technology: yellow and bobbin (non-rumber); among them, chungee and white vague are highly viscous, strong thickening, dissolution Sex, good speed, good carrier, low fermentation, low moisture, low temperatures, low skin, human body easy to digestion, absorption, low heat, low fat, etc. 1. In the food and pharmaceutical products, it has been widely used in white and pharmaceutical products, but there are too many dextrin added in many products or raw materials, leading to decline in product quality. It cannot achieve the expected effect of the product; especially for many health products and plant extracts use...
