A method for detecting a ginsenoside content based on a short-wave imaging spectrum technique

Abstract

A method for detecting a ginsenoside content based on a short-wave imaging spectrum technique is disclosed. According to the method, spectrum collection is performed in a characteristic waveband of 910-2500 nm, spectrum information of a reference blank plate is collected and adopted as a reference spectrum, the distance between a light source and the reference blank plate is adopted as a sample spectrum collecting distance, each sample is subjected to two times of collection, and an average value is made and adopted as final spectrum data, and therefore the data obtained is more complete and representative. A prediction model is built, and the ginsenoside content obtained by a stoichiometric manner and a predicted value obtained by the model are utilized for verification, and the verification proves that the prediction model is reasonable and the method is feasible. The method has advantages of simple operation, easy control, a high analysis efficiency, good analysis quality, and the like. Detection adopting the method does not need chemical agents, and does not cause contamination or loss of samples, thus saving resources and avoiding environment pollution. The method can be adopted as a method for ginsenoside content detection and provides a reliable basis for ginseng quality analysis.

Description

technical field [0001] The invention applies spectrum detection and analysis technology, relates to a ginseng quality measurement technology, specifically a method for detecting ginsenoside saponin content based on short-wave imaging spectrum technology. technical background [0002] Ginseng is also known as Asian ginseng. Because its roots are similar to human nature, people call it ginseng. Because of its good efficacy, it is often called "the king of herbs" and "three treasures of the Northeast". Fleshy roots in East Asia, especially cold regions. Ginseng is a common tonic in Asia. It is often used as medicine. You can see a variety of ginseng drinks or health products made of ginseng extracts in most grass shops and some supermarkets. [0003] As a tonic that is very beneficial to the human body, ginseng has been well-known both at home and abroad. Ginseng likes a warm and cool climate, and it mostly grows in miscellaneous forests on hillsides with a small temperature d...

Problems solved by technology

[0005] The main export regions of ginseng in my country are Japan, Italy, the Netherlands, Germany, Hong Kong and Taiwan of China, etc. Although the export volume and export price of ginseng in my country have increased in recent years, the growth rate is relatively slow, and the exporting country of South Korea It is basically the same as my country's exporting countries, but my country's ginseng export volume and price are even lower than that of Korean red ginseng. In the same export area, Korean red ginseng occupies the high-end market, while Chinese ginseng can only occupy the high-end market. The middle and low market, but the saponin content of Chinese ginseng is not lower than that of Korean red ginseng. The reason that restricts the export volume and price of Chinese ginseng is not only that we have not opened up the market, but more importantly, we do not have a set of advanced detection ginsenosides. It is precisely because of this that customers do not know the added value and advantages of Chinese ginseng, so the international competitiveness is relatively low
