Embodiment Construction
[0049] 1. Example of extraction
[0050] ①, ethanol extraction
[0051] Add 60% ethanol (volume percentage, the same below) to the dried chrysanthemum powder, heat to reflux, and extract 3 times at 70°C for 3 hours each time. The weight ratio is 10:1 to obtain ethanol extract;
[0052] ②, the first concentration and filtration
[0053] Concentrate the ethanol extract under reduced pressure, recover the ethanol under reduced pressure, and filter while hot;
[0054] ③, resin adsorption
[0055] The ethanol concentrate is adsorbed in the AB-8 type macroporous adsorbent resin, the weight ratio of the AB-8 type macroporous adsorbent resin and the ethanol concentrate is 7: 1, after the adsorption is completed, use 70% ethanol (volume percentage, the same below) ) elution, the weight ratio of 70% ethanol and ethanol concentrated liquid is 12:1, and then reclaims the ethanol eluent;
[0056] ④, the second concentration
[0057] Concentrating the ethanol eluent again under reduce...

Abstract
The invention relates to the technical field of extraction of Chinese traditional medicines and particularly relates to a wild chrysanthemum extraction process and a measuring method for total flavonoids in wild chrysanthemums. The wild chrysanthemum extraction process sequentially comprises the following steps of: ethanol extraction, first concentration and filtration, resin adsorption, second concentration, spray drying and the like to obtain a wild chrysanthemum extract. The wild chrysanthemum extraction process and the measuring method for the total flavonoids in the wild chrysanthemums, provided by the invention, have the advantages that the ethanol heating reflux extraction is carried out on the wild chrysanthemums by using an orthogonal experiment method, the wild chrysanthemum extract is not reacted with chrysanthemum components, the total flavonoid component of the wild chrysanthemums can be dissolved to the maximum extent, and therefore, the optimal extraction process is obtained. The extraction ratio of the total flavonoids in the wild chrysanthemums is up to 6.23%, and the content of the total flavonoids is up to 9.5%. The wild chrysanthemums are low in raw material cost and suitable for large-scale industrial production, and therefore, the extraction development for the flavonoids in the chrysanthemums has higher practical significance. Macroporous resin has the characteristics of high adsorbing capacity and high desorption ratio is adopted.
Description
technical field [0001] The invention relates to the technical field of extraction of traditional Chinese medicines, in particular to an extraction process of wild chrysanthemums and a method for determining total flavonoids of wild chrysanthemums. Background technique [0002] Wild chrysanthemum is the dry flower head of chrysanthemum (Chrysanthemum indicum L) in Compositae. It is a commonly used traditional Chinese medicine in my country. It mainly treats symptoms such as headache, dizziness, red eyes, dysphoria in the heart and chest, furunculosis, and swelling. Modern pharmacological studies have shown that chrysanthemum has various pharmacological activities such as treating coronary heart disease, lowering blood pressure, preventing hyperlipidemia, antibacterial, antiviral, anti-inflammatory, and anti-aging. The chemical composition of chrysanthemum is relatively complex, among which flavonoids are its main active ingredients. Current studies have shown that flavonoid...
