The rose belongs to flowersand plants that has the high edible value and the medicinal purposes value.After the rose volatile oil was extracted ,there were massive by-products that had lots of volatile aroma compounds and flavanone matter.With the development of rose industry ,people pay much attention to how to use the comprehensive by-products.Three methods were used to extract and capture the aroma compounds in the rose water and were analysized by GC/MS.22 volatile components were caught by two step distillation method ,the result suggested that it was simplest and effective way among the three methods.The pigment ingredients were studied by the sigle factors and orthogonal expriment. the most favored extracting condition as follow: pH=1,ethyl alcohol density was 65%,temperature was 75℃,the time was 1.5h, the rate of the material to extraction is 1:20.Three components were obtained by paper chromatographic analysis,column chromatographic analysis and determined the three components were flavones and anthocyanins ingredient by BAW2(4:1:2) and color response.The anthocyanins was finally determined cornflower pigment cyanisin-3-glucosid (Cy-3-glu) with AlCl3 and A440/Amax and special hydrolisis condition.The flavanons ingredient was Quercetin through the absorption spectrum,the moved reagent NaOMe and NaOAc and HPLC method with the standarial material.
