| titleOfInvention | Method for extracting stilbene glucoside from polygonum multiflorum |
| abstract | The invention discloses a method for extracting stilbene glucoside in polygonum multiflorum, which comprises the following steps: 1) providing polygonum multiflorum powder; 2) adding an entrainer into the polygonum multiflorum powder, wherein the entrainer is ultrapure water; 3) subjecting Polygoni Multiflori radix powder to supercritical CO 2 Extracting to obtain an extraction product, wherein the extraction temperature is 48-52 ℃, and the extraction pressure is 36-40 Mpa; the extraction product sequentially passes through a separation kettle I and a separation kettle II to obtain a crude stilbene glucoside product, wherein the temperature of the separation kettle I is 43-47 ℃, the pressure of the separation kettle I is 11-13Mpa, the temperature of the separation kettle II is 28-32 ℃, and the pressure of the separation kettle II is 7-9 Mpa; 4) and dissolving the crude stilbene glucoside product by using absolute ethyl alcohol, filtering to obtain filtrate, and drying the filtrate to obtain a stilbene glucoside finished product. The extraction method provided by the invention is convenient to operate, simple in post-treatment, environment-friendly and pollution-free, the extraction rate can reach 5.25%, and the purity can reach 98%. |
