登记用途：Crocin dyes、isolated from Gardenia jasminodes... the crocin dyes are safe for coloring foods、Laboratory reagent、Di-gentiobiose ester、MEDICATION、Methods of Manufacturing: ...total crocin was extracted from saffron stigmas using crystallization method. Ethanol 80% was selected as the best extraction solvent. Crystallization process was carried out in one and two steps at different temperatures. Ethanol 80% was used as crystallization medium. Crocin crystals obtained from the first crystallization had low purity and thus were subjected to the second crystallization. The higher purity crystals were yielded in the second crystallization at -5 degrees C。
