Prediction method for content of raspberry kaempferol-3-O-rutinoside

Abstract

The invention discloses a prediction method for the content of raspberry kaempferol-3-O-rutinoside, and the method comprises the steps: building a prediction model through the temperature difference accumulated temperature and the dynamic changes of the index components of medicinal fruits, and achieving the dynamic prediction of the KR content based on the real-time accumulated temperature; and on the basis of the prediction model, secondary screening is carried out by referring to the fruit weight, so that the screening accuracy is improved. A raspberry medicinal fruit high-quality harvesting decision-making system is established through the prediction method, harvesting period prediction of a production place is given, it is guaranteed that the content of kaempferol-3-O-rutinoside reaches the standard, high quality and high price are achieved, benefits of enterprises and farmers are balanced, and technical support is provided for raspberry industry improvement.

Description

technical field [0001] The invention belongs to the technical field of production of Chinese medicinal materials, and relates to a method for optimizing the quality of raspberry medicinal fruit. [0002] technical background [0003] Raspberry is a bulk medicinal material commonly used in traditional Chinese medicine, and its source is the immature fruit of raspberry (Rubus chingii Hu). The quality of medicinal fruit closely affects the efficacy of its decoction pieces, among which kaempferol-3-O-rutinoside (KR) is one of the important medicinal ingredients, and the "Chinese Pharmacopoeia 2015 Edition" clearly stipulates that The content of the main functional ingredient kaempferol-3-O-rutinoside in the pot should be greater than 0.03%. However, at present, the entire raspberry industry generally has problems such as uneven quality, poor quality stability and consistency, and the price of raspberry medicinal materials has fallen off a cliff in recent years. It is urgent to i...

Problems solved by technology

However, at present, the entire raspberry industry generally has problems such as uneven quality, poor quality stability and consistency, and the price of raspberry medicinal materials has fallen off a cliff in recent years. It is urgent to improve the entire raspberry industry in the form of high quality and high price.

Previous studies have found that the quality of medicinal fruit is closely related to its development period, but farmers mostly judge the maturity period based on experience, ignoring the difference in quality development process that may be brought about by different environments, blindly harvesting, and harvesting following the trend, making the medicinal fruit Shannai The content of phenol-3-O-rutinoside is not up to the standard, the purchase price is low, and pharmaceutical companies cannot purchase qualified raw materials, which also leads to a significant decline in the production efficiency of fruit farmers
