| titleOfInvention | Method for preparing effective part of white flower |
| abstract | A method for preparing an effective part of the white flower. The preparation method comprises the following steps: extracting the white flower of the genus Prunella vulgaris with a volume fraction of 45-55% ethanol for 2-4 times, each time 1-3 h, combining the extracts, and extracting the extract under reduced pressure to obtain an extract; After dissolving the appropriate amount of water, it was separated by macroporous adsorption resin column chromatography, and eluted with pure water, 10%, 30%, 50%, 95% ethanol gradient. The 50% ethanol elution site was collected and subjected to silica gel column chromatography. Separation, elution with chloroform-methanol in a volume ratio of 40:1, 20:1, and collecting a 20:1 fraction, and concentrating. The preparation method of the effective part of P. sinensis is simple and convenient, and the obtained extract is rich in lignin compounds and has various pharmacological activities, and can be used as an effective part of P. sinensis for drug preparation. |
