Embodiment 1

[0017] Embodiment 1 prepares the total flavonoids of Malachite

[0018] Preparation of total flavonoids of malachite grass by solvent extraction and resin adsorption:

[0019] 1 kg of malachite grass powder with 10 meshes and 80% ethanol by volume were soaked and extracted twice, each time the amount of solvent was 10 times of the mass of the medicinal material, and soaked at 40°C for 12 hours each time. Combine the extracts, recover the ethanol solution, concentrate to about 1 times the mass of the medicinal material (about 1 liter), and extract 3 times with 500 ml of petroleum ether each time to obtain a degreasing solution. The degreasing solution is eluted with water (2500 milliliters) and 60% ethanol aqueous solution (2000 milliliters) successively through the pretreated HPD100 macroporous adsorption resin column (about 500 milliliters), and the 60% ethanol eluent is recovered under reduced pressure Ethanol, dried under reduced pressure to obtain 105g of total flavonoids...

[0020] Experimental Example 2 Research on the Anti-Parkinson Effect of Malachite Total Flavonoids

[0021] 1. Experimental materials

[0022] C57BL / 6 mice were purchased from the Animal Experiment Center of Dalian Medical University, and the total flavonoids of malachite grass used were self-made by the above-mentioned process.

[0023] 2. Grouping of animals

[0024] 50 C57BL / 6 mice were randomly divided into 5 groups: blank group, model group, positive drug group (Dopaserazide Tablets (Madopar), Shanghai Roche Pharmaceutical Co., Ltd., batch number: SH1346) and malachite total flavonoids High and low dose groups, 10 rats in each group.

[0025] 3. Modeling and administration methods

[0026] The model group and the high- and low-dose groups were subcutaneously injected with MPTP (purchased from Sigma, batch number: 1001054803) 25 mg / kg, once a day, for 3 consecutive days. On the fourth day, the extract of total flavonoids of Malacock grass was given by intragastric admin...

[0040] 1. Experimental materials

[0041] Methods SD rats, half male and half male, weighing 200±20 g, were purchased from Dalian Medical University. The total flavonoids of malachite used are self-made by adopting the above-mentioned process. Weigh an appropriate amount of total flavonoids from Malachite, and prepare a 5 mg / mL solution for later use.

Abstract

The invention discloses an application of French marigold general flavone extract in the preparation of anti-Parkinson's drugs. A preparation method of the French marigold general flavone extract comprises the following steps: 1, extracting French marigold by an ethanol-water solution at least one time to obtain an extract liquid, and concentrating the extract liquid to obtain a concentrate; 2, degreasing the concentrate by a degreasing solvent to obtain a degreased concentrate; and 3, separating and purifying the degreased concentrate to obtain the French marigold general flavone extract. The weight content of general flavones in the French marigold general flavone extract, detected through colourimetry, is higher than 30%. Pharmacological test proves that the French marigold general flavone extract has high anti-Parkinson's activity, and can be applied to preparations of the anti-Parkinson's drugs individually or after being combined with other drugs. The purity of the general flavones in the French marigold general flavone extract prepared through the method is high, and the preparation method is simple, so the extract is suitable for industrial production; and the French marigold general flavone extract can be used for preparing the anti-Parkinson's drugs.

Description

technical field [0001] The invention relates to a herbal medicine and its application, in particular to a medicine extract with malachite total flavonoids as an active ingredient and its use in preparing anti-Parkinson medicine.
