Embodiment Construction

[0020] The method for extracting flavonoids from wild wrinkled mandarin oranges, the steps are:

[0021] 1. Raw material preparation: take the seven mature wild citrus oranges - wrinkled tangerines, peel them, wash them, chop them up, and dry them in an oven at 50° C., crush and sieve the dried citrus peels (40 mesh) to prepare Make citrus peel powder for later use.

[0022] 2. Extraction process: citrus peel powder→soaking→concentration under reduced pressure→dissolving with ethanol→constant volume

[0023] Weigh 30g of citrus peel powder, infiltrate with 60% ethanol as solvent according to the ratio of material to liquid 1:40, extract for 3 hours, extract at 50°C, then place the reactor in a microwave instrument, extract for 3-5min, and decompress Suction filtration to obtain the total flavonoids extract solution of wrinkled citrus peel, set the volume to 50ml, and set aside for testing.

[0024] 3. Determination of the content of flavonoids in the sample: taking rutin as ...

Abstract

The invention provides a method for extracting flavone by taking wild rough-peel mandarin as a raw material. The method comprises the following steps: wild mandarin-rough-peel mandarin with 70% maturation is subjected to peel taking, washing, chopping, drying, and crushing and sieving (40 meshes) to prepare the rough-peel mandarin peel powder; the powder is infiltrated by using ethanol with the concentration being 60% as a solvent according to a material-liquid ratio being 1:40 g / ml, and then placed in a reactor. The ethanol is used for leaching, then the material is placed in a microwave instrument for microwave extraction, and the flavone is extracted from the rough-peel mandarin peel. The general flavone content in anextract product through detection is 9.42, 9.57 and 8.58 (mg / g). The recovery rate of general flavone in the wild rough-peel mandarin peel is 9.19+ / -0.053 (mg / g). The method avoids the traditional mode by taking mandarin fruits as a raw material for extracting flavones,and fully uses the wide resource, and has the advantages of wide source, simple production technology, good product quality, and low production cost. The utilization value of the wild resource is increased, resource waste and environment pollution are reduced, and wide market prospect, and large economic benefit and social benefit can be generated.

Description

Technical field: [0001] The invention relates to a comprehensive utilization technology of wild tangerines, especially a method for extracting flavonoids from wild tangerines, which belongs to the field of agricultural technology. technical background: [0002] Citrus fruit trees (Citrus) refer to a group of plants of the Citrus family Citrus subfamily of the Rutaceae Citrus subfamily in terms of plant classification. There are various types of varieties. The main varieties circulating in the international market are sweet orange, mandarin orange, grapefruit and lemon. The fruit is rich in a variety of medicinal ingredients, mainly including essential oils, flavonoids, limonoids and their analogues. The types and contents vary with citrus varieties, origins and maturity, among which 7 matures have the highest content. [0003] Citrus flavonoids mainly exist in the form of glycosides and aglycones, and naringin and hesperidin are two important flavanones in the form of glyco...
