| titleOfInvention | The preparation method of ter penoids in a kind of crotons |
| abstract | The invention discloses a kind of preparation methods of ter penoids in crotons.The preparation method includes the following steps：The dry mature kernals of crotons is crushed, with petroleum ether reflux degreasing 3 times, 1 2h every time, medicinal material after degreasing is that 85 95% ethyl alcohol cold soakings extract 13 times with volume fraction, 13 days every time, merges extracting solution, extracting solution is concentrated under reduced pressure to give medicinal extract；By medicinal extract to use petroleum ether, ethyl acetate and water saturated extracting n-butyl alcohol after appropriate water dissolution successively, ethyl acetate portion is obtained；Ethyl acetate portion is detached through silica gel column chromatography, uses volume ratio 50 successively:1、30:1、20:1、10:1 chloroform methanol elution, collects 20:1 elution fraction, concentrates to obtain the final product.The preparation method simple possible of ter penoids, can be enriched with the compound of terpene in crotons provided by the invention, have a variety of effects such as anti-inflammatory, antitumor, anti-oxidant, can be prepared applied to drug as the active component of crotons. |
