| titleOfInvention | A method of preparing tannin effective constituents in myrobalan |
| abstract | The invention discloses a kind of methods preparing tannin effective constituents in myrobalan, and steps are as follows：By myrobalan's powder absolute ethyl alcohol ultrasonic extraction, extracting solution is concentrated under reduced pressure into medicinal extract；Large pore resin absorption column chromatographic isolation will be used after the appropriate water dissolution of medicinal extract, successively with pure water, the ethanol gradient elution of volume fraction 20%, 40%, 60%, 80%, 90%, 95%, 90% alcohol elution is collected, then is detached through silica gel column chromatography, uses volume ratio 65 successively:1、55:1、45:1、35:1、25:1、10:1 chloroform methanol elution, collects 25:1 elution fraction, concentrates to obtain the final product.The preparation method can effectively obtain the tannin effective constituents in myrobalan, have anti-oxidant, antibacterial, antitumor activity, can be prepared applied to drug as the active component of myrobalan. |
