Effects of Soaking Treatment with Four Kinds of Agents on Functional Components and Antioxidant Activity of Jinsihuangju
To show the effects of different agents on functional components and antioxidant activity of cuttage from Jinsihuangju and determine the best suitable soaking treatment reagent.Four kind of the flowerheads samples were collected after soaking treatment with water(Q1),rooting powder(Q2),chlorothalonil(Q3),and rooting powder+chlorothalonil(Q4).The contents of functional compo-nents in Jinsihuangju were measured by Folin-ciocalteu,Phehol-vitriol and Aluminum nitrate method,and the antioxidant capabilities on DPPH,Fe3+and ABTS were used to evaluate the antioxidant ac-tivity of the four species of Jinsihuangju.Results showed that the contents of phenolics,polysaccha-rides and flavonoid of Jinsihuangju were significantly affected by different agents soaking treatment.The polysaccharide content was the highest at Q3(26.81 mg/g),which was higher than those in Chuzhou chrysanthemum flowers and lower than those in jujube.The contents of phenols and fla-vonoids were the highest at Q2(48.59 and 61.88 mg/g,respectively),which were consistent with those of Chuzhou chrysanthemum flowers and higher than those of other chrysanthemum varieties and small berry foods(blueberry and blackberry).The Fe3+reduction ability of polysaccharide and total phenol were significantly affected by different agents soaking treatment.The Fe3+reducing capacity of polysaccharides was the highest at Q2(138.34 umol/g),which was 38.6 times that of Chuzhou chrys-anthemum flowers.The Fe3+reducing capacity of total phenol was the highest at Q3(86.77 umol/g),which was about 3/8 of that of Chuzhou chrysanthemum flowers.The DPPH and ABTS cation radical scavenging activities of polysaccharide and total phenol had no significantly affected by different agents soaking treatment.Synthesizing the difference between agents soaking treatment and functional components,antioxidant capacity of Jinsihuangju,the most suitable agents soaking treatment should be the rooting powder(Q2).
