| titleOfInvention | A kind of preparation method of kadsura longepedunculata lignin ingredient |
| abstract | The invention discloses a kind of preparation methods of kadsura longepedunculata lignin ingredient, and steps are as follows：Kadsura longepedunculata is extracted 13 times with 65 75% ethyl alcohol cold soaking of volume fraction, 3 5d, merges extracting solution every time, and extracting solution is concentrated under reduced pressure to give medicinal extract；Gained medicinal extract is diluted with water, uses petroleum ether, ethyl acetate and water saturated extracting n-butyl alcohol successively, is concentrated under reduced pressure, obtains acetic acid ethyl ester extract；By acetic acid ethyl ester extract large pore resin absorption column chromatographic isolation, first 7 column volumes are rinsed with 10% ethyl alcohol and remove big polar components, then use 75% ethanol elution, 10 column volumes, 75% eluent is collected, then detach through silica gel column chromatography, successively with volume ratio 46:1、23:1、17:1、5:1 chloroform methanol elution, collects 17:1 elution fraction, concentrates to obtain the final product.Preparation method is simple for this, and obtained lignin ingredient has significant antitumor, antiviral activity, can be used for drug preparation. |
