Embodiment 1

[0018] After crushing 100g of rhizomes, pass through a 40-mesh sieve, add 1.5L of water, stir and soak for half an hour. Add a volatile oil extractor, pre-boil for 4 hours under reflux, and collect volatile oil from the lower end of the measuring device. Add anhydrous sodium sulfate to the volatile oil to remove water. Read the oil content of the medicinal material, and calculate the volatile oil content of the medicinal material to be about 0.901%. The aqueous solution was filtered, and the filtrate 1 and the residue 1 were retained. Continue to add 10 times of water to the filter residue 1 and continue to slightly boil and reflux for 3 hours, and filter to obtain the filtrate 2 and filter residue 2 . Combine the filtrate 1 and the filtrate 2, concentrate in vacuo, combine the filtrate 1 and the filtrate 2, concentrate in vacuo, add starch to the concentrated solution, the amount is 10-30% of the dry matter of the polysaccharides of Rhizoma chinensis, and the relative densi...

Embodiment 2

[0020] After crushing 150g of fenugreek, pass through a 40-mesh sieve, add 1.5L of water, stir and soak for half an hour. Add a volatile oil extractor, pre-boil for 4 hours under reflux, and collect volatile oil from the lower end of the measuring device. Add anhydrous sodium sulfate to the volatile oil to remove water. Read the oil content of the medicinal material, and calculate the volatile oil content of the medicinal material to be about 0.867%. The aqueous solution was filtered, and the filtrate 1 and the residue 1 were retained. Continue to add 10 times of water to the filter residue 1 and continue to slightly boil and reflux for 3 hours, and filter to obtain the filtrate 2 and filter residue 2 . Combine the filtrate 1 and the filtrate 2, concentrate in vacuo, combine the filtrate 1 and the filtrate 2, concentrate in vacuo, add starch to the concentrated solution, the amount is 10-30% of the dry matter of the polysaccharides of Rhizoma chinensis, and the relative dens...

Embodiment 3

[0022] After crushing 150g of fenugreek, pass through a 40-mesh sieve, add 1.5L of water, stir and soak for half an hour. Heated in a water bath at 90°C for 4h. Filter the aqueous solution, continue to add 10 times of water and continue heating in a water bath at 90°C for 3 hours, combine the two filtrates, concentrate in vacuo to 1 / 4, add absolute ethanol to the concentrated solution until the ethanol concentration reaches 80%, and alcohol precipitation at 4°C overnight . Centrifuge (4800r / min, 10min), wash the precipitate twice with absolute ethanol, acetone, and anhydrous ether in sequence, evaporate the organic reagents, and dry under vacuum at 55°C to obtain the crude polysaccharide of A. Weighing, the calculated yield of the polysaccharides of Rhizoma chinensis is 8.061%.

Abstract

The invention belongs to the field of Chinese medicinal herb development. The method aims at improving the utilization ratio of natural plant Chinese medicinal herbs, utilizing on the basis of the traditional method and integrally extracting the active components contained in elsholtzia haichowensis sun. The method comprises the following steps: crushing a commercially available elsholtzia haichowensis sun medicinal material dried in the shade into powder capable of being screened through sieve with the mesh size of 40-80 meshes, soaking, and extracting volatile oil through a steam distillation method; filtering a water solution, retaining filter liquor and filter residues, adding a certain amount of starch into the filter liquor, and carrying out spray drying to obtain elsholtzia haichowensis sun polysaccharide; airing the filter residues, adding ethanol for organic reflux, and extracting total flavone. The method disclosed by the invention can be used for realizing the integrated utilization of elsholtzia haichowensis sun resources and has the advantages of simple process, less production process and low cost.

Description

technical field [0001] The invention relates to the field of processing and utilization of Chinese herbal medicines and the development of by-products, in particular to extracting volatile oil, polysaccharides and total flavonoids from Rhizoma radicis. Background technique [0002] Herba Moslae (Herba Moslae), also known as E.ciliata (Thunb) Hyland], usually refers to the dry aerial part of Lamiaceae plant Mosla chinensis Maxim or Mosla chinensis 'jiangxiangru'. Spicy and sweet in taste, warm in nature, non-toxic. It is recorded in "Famous Doctors", "Picture Herbal Classic", and "Compendium of Materia Medica" in ancient my country. Jiangxiang is an authentic medicinal material in Jiangxi with a long history of cultivation. It is mainly distributed in Xinyu City, Zhangshu City, Fenyi County, Yushui District and other places. In summer, when the stems and leaves are luxuriant and the flowers are in full bloom, choose sunny days to harvest, remove impurities, and dry in the s...
