Synthesis method

1. Both oxytocin and vasopressin are nonapeptides. There is a basic amino acid residue in the vasopressin molecule, and their isoelectric points are different. The isoelectric point of oxytocin is 7.7 and that of vasopressin is 10.9, which means that vasopressin is highly alkaline. When the extract containing these two hormones is passed into an artificial zeolite column, vasopressin easily forms positively charged ions and most of them are adsorbed, while oxytocin flows out through the zeolite column. The effluent oxytocin solution can be treated with bentonite to obtain purer oxytocin.

Extraction of posterior pituitary gland dry powder ↓water separation ↓zeolite column to remove impurity protein ↓acetic acid

Bentonite adsorption ↓bentonite desorption ↓oxytocin acetate

The pituitary gland Add 100g of dry leaf powder and about 30g of quartz powder into 1.4L of distilled water, grind in a ball mill and extract for 45 minutes, centrifuge, and collect the supernatant. Add 1.4L, 1.3L, and 1.3L of water to the residue and extract 3 more times according to the above method. Combine the supernatants from 4 times of centrifugation. Add 1500g of the treated artificial zeolite to 20L of 0.25% acetic acid solution, stir and put it into the exchange column. When the 0.25% acetic acid solution in the exchange column drops to 2 to 3cm below the surface of the zeolite, immediately add the extraction solution and adjust the flow rate appropriately. , collect the white turbid liquid that begins to flow out of the adsorption column. When the liquid level of the extraction liquid drops to the surface of the zeolite, add distilled water immediately, and stop collecting when the turbid liquid flows out. The extract solution flowing through the zeolite was adjusted to pH=3.5 with glacial acetic acid, then rapidly heated to 95°C in a water bath for 3 minutes, cooled immediately, and placed in a cold room at 0 to 5°C overnight. Filter the next day to get a clear filtrate. Then, add the previously treated 10% bentonite slurry (usually 3ml per 100ml) to the filtrate while stirring, and stir continuously for 1 hour. The supernatant should be checked for complete adsorption (check with 20% sulfosalicylic acid solution, it should be No precipitation occurs), if the adsorption is incomplete, additional bentonite slurry should be added for adsorption. The 2 bentonite precipitations merged. The bentonite was then desorbed with 1% acetic acid solution. The total dosage is 5L and desorbed in 4 times. The dosages are 1.6L, 1.4L, 1.2L and 0.8L respectively. The 4 desorption liquids are combined. Determine the content of oxytocin and vasopressin in the desorption solution, and calculate the oxytocin potency. If the vasopressin does not exceed the limit, the oxytocin solution is obtained.

Purpose

1. It has a stimulating effect on smooth muscles and can cause the contraction of uterine smooth muscles, so it has an oxytocin effect. It can be used to induce labor, induce labor and uterine bleeding caused by weak uterine contractions after abortion. Intranasal instillation can promote milk excretion. It also has a slight hemostatic effect.

Maintain the reaction temperature at 110~120℃ (strictly control the reaction temperature to prevent explosion), react for 3 hours:

After the reaction, quickly cool to room temperature. Remove the potassium fluoride residue by suction filtration, add water to the filtrate and wash it, let it stand and separate the water layer (dimethyl sulfoxide can be recovered), wash the oil layer twice with water, distill under reduced pressure at 2.73kPa, collect 176~180℃ The distillate is the finished product 2,4-dinitrofluorobenzene.

Purpose

1. Used as a chromogenic reagent for the photometric determination of organic amines and neomycin. It is also used for the preparation of fluoride ion selective electrodes and the automatic flow injection dynamic potential method for the determination of paracetamol, isoniazid and phenoxypropylamine. Used as a chromatographic derivatization reagent for the determination of primary amines, secondary amines, alcohols, phenols, thiols, imidazole and carbonyl compounds.

2. Used as a reagent for protein analysis and a reducing agent for the determination of phenol, morphine, amino acids, aldehydes, and oximes. [18]

Storage method

This product should be sealed and stored in a dry place away from light.

Synthesis method

This strain is an alkaloid extracted from the gum that precipitates when the all-alkali plant (Rauwolfia genus) of the Apocynaceae family (Rauwolfia) is concentrated in the acid permeate solution, and is produced by chemical synthesis. However, there is currently no synthetic method to produce value, and they are all extracted from Rauwolfia rauwolfia. Take the colloidal substance that precipitates when the acidic percolation liquid of Rauwolfia vulgaris is evaporated and concentrated, add ethanol and glacial acetic acid to obtain an acidic ethanol solution, and then extract it with chloroform to obtain a chloroform solution. It is extracted with acetone in a sexual solution and refined to obtain reserpine. Since this product is highly susceptible to oxidation and deterioration, the entire production process must be conducted away from light. The total yield is about 0.01% for crude drugs and about 0.5% for colloids.

Purpose

Biochemical research. Medicine (antihypertensive drugs)
