Embodiment 1

[0033] Take 1kg of oryzanol, heat and dissolve it with about 8kg of acetone, let stand at room temperature to precipitate crystals, filter, and dry. The above process was repeated 10 times for the dried crystals. The content of 24-methylene cycloartenyl ferulic acid ester reaches more than 99%.

Embodiment 2

[0035] 1. Chromatographic conditions and system suitability test: octadecylsilane bonded silica gel is used as filler; methanol-acetonitrile (40:60) is used as mobile phase; flow rate is 1.5ml / min; detection wavelength is 327nm; sensitivity is 0.005 AUFS. The number of theoretical plates should not be less than 2000 according to the calculation.

[0036] 2. Preparation of the test solution: Accurately weigh 10 mg of the commercially available oryzanol raw material and 10 mg of the present invention, put them in a 10 ml measuring bottle, add water to dissolve and constant volume, and shake well to obtain the test solution.

[0037] 3. Determination: Accurately draw 10 μl of the test solution, inject it into a liquid chromatograph, record the chromatogram, and check the percentage content of each component by the area normalization method.

Abstract

The invention discloses a composition preparation of 24-methylene cycloartenol feruloyl esterase, and a purification process thereof. The purity of 24-methylene cycloartenol feruloyl esterase purified by the purification process can reach more than 80%. The composition disclosed by the invention contains 24-methylene cycloartenol feruloyl esterase and surface active agent, wherein, the surface active agent is selected from Tween 80, polyethylene glycol 400 or mixture thereof. Meanwhile, the invention also discloses an injection of the composition, in particular to freeze-dry powder injection for injection.

Description

technical field [0001] The invention discloses a process for purifying 24-methylenecycloartenol ferulic acid ester and its preparation. Further, the invention discloses a process for purifying cycloartenol ferulic acid from oryzanol raw materials by using recrystallization technology Ester process. Background technique [0002] With the gradual acceleration of the pace of life and work in modern society, the sub-health status of modern people is not optimistic. According to statistics, patients with autonomic disorders, menopausal syndrome, primary dysmenorrhea, premenstrual tension, etc. due to autonomic dysfunction, lead to the imbalance of sympathetic and parasympathetic nerves, and the incidence of non-organic diseases is increasing year by year. trend. [0003] Autonomic disorders are usually caused by mental trauma, long-term tension and fatigue, which lead to weakening of the function of the cerebral cortex, excessive excitement and rapid fatigue. Menopausal syndro...
