Abstract

The invention discloses a method for extracting suaveolic acid A. The method is characterized by comprising steps as follows: getting the aboveground part of head-shaped suaveolens as the raw material; crushing the tissue, and carrying out enzymolysis by virtue of cellulose, so as to obtain the raw material subjected to enzymolysis; carrying out supercritical CO2 extraction; separating and collecting to obtain triterpenes extractive; then purifying by high-pressure silica gelcolumn chromatography; collecting fraction of the suaveolic acid A; concentrating in a pressure reducing way; and recrystallizing to obtain the suaveolic acid A. The method disclosed by the invention is simple in operation, suitable for large-scale production, low in energy consumption, low in pollution and short in production period, and is an environment-friendly production technology.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine chemistry and relates to a method for extracting behenic acid A. Background technique [0002] Asprellic acid A (Asprellic acid A), the molecular formula is C 30 h 48 o 5 , molecular weight 488.71, colorless prism, mp.298-304℃. Behenic acid A is from the labiatae (Labiatae) capitula Hyptis capitata Jacq. A triterpenoid isolated from aerial parts. Pharmacological studies have shown that behenic acid A has cytotoxic activity against A-549, HCT-8, and P388. Its ED50 (μg / ml) is 5.9, 4.2, 6.7 in turn. [0003] In the prior art, there is no report on the production process for preparing behenic acid A. Contents of the invention [0004] The purpose of the present invention is to provide a method for extracting behenic acid A. [0005] To achieve the above object, the present invention adopts the following technical solutions: [0006] (1) Cut the above-ground part of Cinn...
