Embodiment Construction

[0017] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] 1 Materials and methods

[0019] 1.1 Materials

[0020] 1.1.1 Test material

[0021] Lanzhou lily (LiLum davidi) was purchased from Lanzhou City; Shangluo wild lily (Lilium brownii) was collected from Danfeng County.

[0022] 1.1.2 Main reagents

[0023] Phenol, concentrated sulfuric acid, 95% ethanol, glucose, chloroform, and n-butanol were all analytically pure.

[0024] 1.2 Method

Abstract

The invention discloses an extraction method of crotalaria sessiiflora polysaccharide. An optimal technology for extracting lilium brownii polysaccharide, which is optimized through an orthogonal test, is as follows: the extraction time is 2.5h, the temperature is 80 DEG C, the solid-liquid ratio is 1 to 20g/mL and the crude polysaccharide extraction rate is 20.38 percent. A technology for extracting the lilium brownii polysaccharide, which is optimized through a response surface method, is as follows: the extraction temperature is 76 DEG C, the extraction time is 1 hour and 40 minutes, the material-liquid ratio is 1 to 20g/mL and the crude polysaccharide extraction rate is 30.78 percent. The research shows that the response surface method is stably feasible to optimization of technological conditions of a lilium brownii polysaccharide water extraction method, so that theoretical supports are provided for further developing and utilizing Shangluo lily bulbs.

Description

technical field [0001] The invention relates to a method for extracting plant components, in particular to a method for extracting wild lily polysaccharide. Background technique [0002] Lilium (Lilium) is a herbaceous plant of the subclass Liliaceae of monocotyledonous plants. It is named "Lily" because its bulb is composed of many scales. Its bulbs contain a lot of nutrients such as starch, protein, fat, calcium, iron, etc., and some of them can be eaten; its flowers and bulbs are often used as medicinal materials, which have various functions such as clearing the lungs and relieving coughs, soothing the mind, and beautifying the skin. Polysaccharides, alkaloids, saponins and flavonoids are antibacterial active substances in lily, and their medicinal value is anticancer, antiallergic and improving immunity. Lilium brownii (Lilium brownii) mainly grows in the grass on the middle and lower part of the ridge with a steeper slope. Its bulbs are edible and also used as medicin...
