Embodiment 1

[0047] Grind the dried fruit of Brassica fructus into 200 g of coarse powder, add 10 times the weight of methanol with a volume concentration of 70% for extraction, heat and reflux in a water bath at 90°C for 3 times, each time for 1.5 hours, filter, and combine the filtrates, Recover methanol or ethanol from the filtrate and concentrate under reduced pressure without alcohol smell, add water to make up to 5000ml (concentration 0.04g crude drug amount / ml), filter through four layers of gauze until the clear liquid, filter, pass through HP-20 macroporous adsorption resin column (upper The volume of the sample liquid is 10 times the volume of the filled macroporous adsorption resin), and the flow rate of the upper column is 2BV / h; wash with 10 times the water, discard the washing liquid, and fill the sample with 15 times the volume of the macroporous adsorbent resin and a volume concentration of 30%. Ethanol elution, the elution flow rate is 1BV / h; the eluate is collected, the el...

Embodiment 2

[0049] Take the dried fruit of Brassica fructus and crush it into 500g of coarse powder, add 15 times the amount of methanol with a volume concentration of 80% according to the weight for extraction, heat and reflux extraction in a water bath at 80°C for 4 times, each time for 1 hour, filter, combine the filtrate, the filtrate Recover methanol or ethanol and concentrate under reduced pressure without alcohol smell, add water to make up to 9000 ml (0.056g medicinal materials / ml), filter through four layers of gauze until the clear liquid is filtered, and pass through HP-20 macroporous adsorption resin column (loading solution The volume is 20 times the volume of the resin), and the flow rate on the column is 2BV / h; wash with 10 times of water, discard the washing solution, and elute with ethanol with a volume concentration of 90% and 10 times the volume of the macroporous adsorbent resin, and collect the washed Ethanol was removed, and the elution flow rate was 3 BV / h; ethanol w...

Embodiment 3

[0051] Take the dried fruit of Brassica fructus and crush it into 500 g of coarse powder, add 5 times the amount of 100% methanol according to the weight to extract, heat and reflux in a water bath at 80°C for 3 times, each time for 0.5 hours, filter, combine the filtrate, and recover methanol from the filtrate Or ethanol and concentrated under reduced pressure without alcohol smell, add water to make up to 7500 ml (0.067 g medicinal material / ml), filter through four layers of gauze to a clear liquid, filter, pass through AB-8 macroporous adsorption resin column (the volume of the sample solution is 10 times the volume of the resin), and the column flow rate is 4 BV / h; wash with 10 times of water, discard the washing liquid, and elute with 15 times the volume of the macroporous adsorption resin, and the volume concentration is 70% ethanol, and the elution flow rate is 3BV / h; collect the eluent, concentrate the eluent to the extract under reduced pressure, and dry it in vacuum a...

Abstract

The present invention relates to a method for the preparation and quality detection of a traditional Chinese medicine extract, in particular to a method for the preparation and quality detection of a total flavonoids extract of B. Ethanol reflux extraction, concentration, suspension with water, macroporous adsorption resin column chromatography elution (ethanol-water system), concentration, and vacuum drying to obtain the total flavonoids extract of B. The preparation method is reasonable, stable, and has a short production cycle, and is suitable for industrialized production. The present invention adopts ultraviolet-visible spectrophotometry, high-performance liquid chromatography, one measurement and multiple evaluation methods, and the area normalization method to measure the total flavonoids in the flavonoids extract of the flavonoids. The content of the total flavonoids of Tsao Kuo is accurate, stable and simple to operate, and the Tsao Tsao Tsao Tsao total flavonoids extract prepared by the present invention has pharmacological effects such as anti-inflammation and antibacterial.

Description

technical field [0001] The invention relates to a preparation and quality detection method of an extract of traditional Chinese medicine, in particular to a preparation and quality detection method of a total flavonoids extract of Brassica fructus. Background technique [0002] Tsaoguo, also known as Baicaoguo and Guangxi Tsaoguo, is a plant of the genus Cardamom in the ginger family ( Amomum paratsao-ko S.Q.Tong et Y.M.Xia) are cultivated on a large scale in Guangxi and other regions. It is used as a substitute for grass fruit in Guangxi Zhuang people for Titian or medicinal purposes. It is clinically used to treat abdominal fullness and cold pain, nausea and vomiting, food accumulation, phlegm, malaria and other diseases. However, so far, except for the volatile oil components ([Title] GC-MS analysis of the volatile oil of the grass fruit [Authors] Qin Lanfang, Huang Yunfeng, Hu Qimin, etc., Guangxi Academy of Traditional Chinese Medicine [Title] Traditional Chinese Medic...
