| titleOfInvention | A kind of method for extraction and purification of Prunella vulgaris general flavone and its application |
| abstract | A kind of method for extraction and purification of Prunella vulgaris general flavone, step are as follows: (1) take Prunella vulgaris pulverizing medicinal materials to be sieved, add the 1-30 times of ethyl alcohol for measuring 5-95%, refluxing extraction 1-3 times, each 1-5 h is filtered, and merging filtrate obtains extracting solution；(2) extracting solution heating is concentrated into concentration is 0.05-0.5 g/mL, then adjusting pH value is 1-7, obtains sample solution；(3) by the sample solution, upper NKA-9 macroporous absorbent resin, after the removal of impurities of 1-10 BV water, then with the 10-95% ethanol elution of 1-10BV；(4) purifying process of the continuous several times Jing Guo step 3 obtains enriched substance, be dried under reduced pressure to powder or medicinal extract to get.The present invention also provides application of the Prunella vulgaris general flavone in preparation treatment liver-cancer medicine, by pharmacological effect research shows that Prunella vulgaris general flavone has apparent anti-liver tumour activity, and be in apparent dose-effect relationship, theoretical and experimental basis is provided by the anti-liver tumour new drug and industrial production of raw material being worth with extensive clinical use value and business development of Prunella vulgaris general flavone enriched substance to develop. |
