Embodiment 1

[0031] The preparation of embodiment 1N-(2-hydroxyethyl) linolenamide, dihydroxy octadecadienoic acid, linolenic acid fructoside and palmitic acid sorbitol ester

[0032] 1) Supercritical extraction: commercially available rape pollen (produced by Baikang Bee Industry, Xuancheng City, Anhui Province) was dried under reduced pressure at 60°C for 24 hours, and then the dried pollen was dried at 40°C and the pressure of the extraction kettle was 40MPa. Separation kettle I temperature 35 ℃, pressure 12MPa, separation kettle II temperature 25 ℃, pressure 5MPa, the weight concentration of pollen weight 8% is 95v / v% ethanol as entrainer to carry out supercritical carbon dioxide (45L / hour circulation consumption) extraction After 2.0 hours, the supercritical extraction fraction was obtained, and the supercritical extract was collected.

[0033] 2) Macroporous resin enrichment: use macroporous resin column chromatography (DA201 resin with 10 times the sample mass, Tianjin Huida Chemic...

Embodiment 2

[0037] The preparation of embodiment 2N-(2-hydroxyethyl) linolenamide, 1-linolenic acid glyceride, dihydroxy octadecadienoic acid, linolenic acid fructoside and palmitic acid sorbitol ester

[0038] 1) Extraction: take rapeseed pollen after breaking the wall, pulverize, heat and reflux 3 times with 95% ethanol aqueous solution with a volume concentration of 10ml / g rapeseed pollen, filter, combine the filtrates, and recover the solvent under reduced pressure to obtain a relative density of 1.28 The liquid extract is dissolved in water at the ratio of 2ml water / g liquid extract, and is extracted successively with sherwood oil, chloroform and ethyl acetate. colorless. Take the ethyl acetate extraction part, recover the solvent under reduced pressure, and evaporate to dryness to obtain the effective part.

[0039] 2) Column chromatography: Mix the above-mentioned effective parts with silica gel on the column, perform silica gel (300-400 mesh) column chromatography (silica gel 10 ...

Abstract

The invention discloses the application of a 1-class long-chain fatty acid derivative shown in a formula 5 or a plant extract containing the 1-class long-chain fatty acid derivative in preparing a preparation for suppressing the activity of aromatase and a medicine composition for preventing or treating prostate hyperplasia diseases. According to the application disclosed by the invention, the new application field of the compound is opened up. Meanwhile, a new approach is also provided to the prevention and the treatment of the symptom in the field. The concrete content is shown in the formula 5.

Description

[0001] This application is a branch of an application whose filing date is April 30, 2008, application number is 200810036931.1, and the title of the invention is "A Class of Long-chain Fatty Acid Derivatives or the Application of Plant Extracts Containing It in Inhibiting Aromatase Activity". case application. technical field [0002] The invention relates to a new application of a class of long-chain fatty acid derivatives or plant extracts thereof. Background technique [0003] Benign prostatic hyperplasia (BPH) is a common physiological lesion in elderly men. When the lesion causes a series of symptoms such as urinary obstruction, it is called benign prostatic hyperplasia. Autopsy reports of 1075 cases abroad showed that: at the age of 25 to 30, 10% of men could see early benign prostatic hyperplasia lesions under the microscope; as the age increases, the incidence of benign prostatic hyperplasia diagnosed by histology also increases accordingly; By the age of 51 to 60,...
