| Abstract: | The techniques of separation of anthocyan from grape seeds were srudied. The grape seeds after being soaked in cold methyl alcohol for 12 h were extracted under reflux 3 times (2 h each time) at 70 ℃. The raffmate was concentrated under vacuum into extract, which was then dissolved in boiling water and filtered. The filtrate was extracted 2 times by nbutanol. The extract was concentrated under vacuum, and then dried under vacuum to give the final product anthocyan.Purity of anthocyan was above 90％. |
