Embodiment 1

[0028] The raw medicinal materials and quality ratios used to extract the compound total flavonoids are as follows:

[0029]

[0030]

[0031] During preparation, the technological process is as follows:

[0032] Take an appropriate amount of pure Chinese herbal medicine combination with the proportioned dosage, mix it evenly, put it into the extractor, add 15 times the amount of 60% ethanol to reflux for 1 hour; collect the extract, and use 10 times the amount of 60% ethanol to reflux and extract once; Combine the two extracts, filter, recover ethanol until there is no alcohol smell, concentrate and dry to obtain the crude extract of the traditional Chinese medicine compound.

[0033] The crude extract of traditional Chinese medicine compound was redissolved with water to the crude drug concentration of 0.25g / ml, which was used as the sample solution. The macroporous resin was D101 type (Tianjin Haiguang Chemical Co., Ltd.), and the sample loading flow rate was 1 column...

Embodiment 2

[0035] The raw medicinal materials and quality ratios used to extract the compound total flavonoids are as follows:

[0036]

[0037] During preparation, the technological process is as follows:

[0038] Take an appropriate amount of pure Chinese herbal medicine combination with the proportion of medicinal materials, mix it evenly, put it into the extractor, add 20 times the amount of methanol to soak for 24 hours; collect the extract, and soak the dregs with 15 times the amount of methanol for 24 hours; combine the two extractions liquid, filtered, recovered methanol, concentrated and dried to obtain crude extract of traditional Chinese medicine compound.

[0039]The crude extract of traditional Chinese medicine compound was redissolved with water to the crude drug concentration of 0.25g / ml, which was used as the sample solution. The macroporous resin was DM130 (Tianjin Haiguang Chemical Co., Ltd.), and the flow rate of the sample was 1 column volume / hour (BV / h) . Wash w...

Embodiment 3

[0041] The raw medicinal materials and quality ratios used to extract the compound total flavonoids are as follows:

[0042]

[0043] During preparation, the technological process is as follows:

[0044] Take an appropriate amount of pure Chinese herbal medicine combination with the proportioned dosage, mix it evenly, put it into an extractor, add 40 times the amount of acetone for percolation extraction, filter the extract, recover acetone, concentrate and dry to obtain the crude extract of Chinese medicine compound.

[0045] The crude extract of traditional Chinese medicine compound was redissolved in water to the crude drug concentration of 0.25g / ml, which was used as the sample solution. The macroporous resin was D301 type (Tianjin Haiguang Chemical Co., Ltd.), and the sample loading flow rate was 1 column volume / hour (BV / h) . Wash with water at a flow rate of 2BV / h until almost colorless. With a flow rate of 2BV / h, the active ingredients were eluted with a total of 6...

Description

technical field [0001] The invention relates to the fields of natural medicinal chemistry, household products, disinfection products and cosmetics, in particular to a compound total flavonoids of traditional Chinese medicine for resisting Staphylococcus aureus, Escherichia coli and Candida albicans and a preparation method thereof. Background technique [0002] At present, most antibacterial additives at home and abroad are mainly synthetic compounds. With the requirements of naturalness, safety and environmental protection, natural plant additives are more and more popular. However, the development of natural antibacterial additives is less, which cannot meet the requirements of consumers, especially the development of compound antibacterial additives of Chinese herbal medicines, which is very rare. [0003] The invention proposes a new method for extracting the total flavonoids of the traditional Chinese medicine compound, and the total flavonoids of the traditional Chines...
