Embodiment 1

[0054] Extract functional nutrients

[0055] like figure 1 As shown, the mature soybean hybrid seeds to be detected are cut off with a paper blade one by one on the opposite side of the hilum (subject to the fact that the germ, radicle, and hypocotyl are not damaged at all) (detection of immature soybean cotyledon In the case of immature soybean cotyledons, freeze-dry the immature soybean cotyledon for 24 hours by a conventional freeze dryer, grind and pulverize into a powder) 10 mg is added to a 1.5 ml eppendorf centrifuge tube, and at the same time, β-apocarotene aldehyde containing 0.25 μg / ml is added (β-Apo-8'-carotenal (trans)) and 3 μg / ml tocol (Tocol) internal standard ice-cold n-hexane reagent 500 μl, shake the oscillator for 10-20 seconds, ultrasonic at 4 ° C for 8-10 minutes , then refrigerated in the dark for 15-30 minutes, centrifuged at 13,000 rpm for 10 minutes, took 300-400 μl of the supernatant for HPLC analysis of carotenoids such as vitamin E and lutein; too...

Abstract

The invention provides a method for rapidly detecting the nutrient content of a plant, in particular the nutrient content of a soybean polygene polymerization breeding filial generation. The method comprises the following steps of: extracting primary samples of substances, such as a water-soluble substance, namely, isoflavone and fat-soluble substances, namely, vitamin E, xanthophyll, carotene and the like at the same time; and performing a high performance liquid chromatography (HPLC) two-step analysis method to realize synchronous analysis and detection of various functional nutrients through primary samples. Therefore, the method has the advantages of accelerating the selection process of breeding generations, cultivating a new soybean variety with a high added value, shortening detection time, reducing the investments on manpower, material resources and financial resources and reducing the pollution of wastes to the environment.

Description

technical field [0001] The present invention relates to a method for quickly extracting and detecting plant nutritional components, especially the content of functional nutritional components in soybeans, in particular to a method capable of synchronously and rapidly extracting functional nutritional components of hybrid offspring of soybean multi-gene polymerization breeding, and using HPLC to obtain It has a detection function, which can be used for qualitative and quantitative methods, so that its hybrid offspring can be quickly screened. Background technique [0002] Many plant seeds, especially soybean seeds are not only rich in high-quality vegetable protein and fatty acids, but also contain a variety of functional nutrients such as isoflavones and vitamin E. Especially in recent years, with the improvement of living standards, consumers' demand for functional nutrients such as soybean isoflavones and vitamin E has risen sharply. However, among the existing soybean va...
