果糖处理对费菜总黄酮及其相关酶的影响
Effect of fructose treatment on flavonoids content and the related enzymes in Sedum aizoon L.
摘要
Abstract
In this paper,the effects of water culture temperature (20,25,28 ℃),photoperiod (8 h/16 h,12 h/12 h,16 h/8 h) and fructose treatment(0,10,20,30,40 mmol/L)on flavonoid content and anabolism related enzyme activity in Sedum Aizoon L.were investigated.The results indicated that optimal water culture conditions was 25 ℃,16 h/8 h.30 mmol/L fructose treatment could effectively improve the content of flavonoids in Sedum aizoon L.,which the treatment group was 1.37 mg/g higher than the control group (fresh weight).Compared with control group,fructose treatment could delay the decrease of the activities of phenylalanine ammonia lyase (PAL),polyphenol oxidase (PPO),chalcone synthase (CHS) and chalcone isomerase (CHI),and inhibit the peroxidase (POD) activity.It suggested that fructose treatment regulated the enzymes activities of flavonoids metabolism and promoted the accumulation of flavonoids during culturing.These results laid a theoretical basis for enhancement of the bioactive compounds contents and nutritional values of Sedum aizoon L.关键词
