论文分两个部分进行,第一部分是在确定了香蕉中酪氨酸酶的最佳吸收峰518.5nm的条件下,在相同反应时间内,研究34μmol/L,38μmol/L,42μmol/L,46μmol/L,50μmol/L不同浓度的3-苯基-4-氨基-5-硫酮-1,2,4-三唑（APTT）对香蕉酪氨酸酶的抑制效果,结果表明最佳作用浓度为50μmol/L.在最佳浓度50μmol/L作用下,确定最佳作用时间为7min.在最佳作用浓度50μmol/L及最佳作用时间7min下,研究20℃、25℃、30℃、35℃、40℃条件下APTT对香蕉酪氨酸酶的抑制效果,结果表明最佳温度为20℃.分别对浓度、温度、时间进行三因素三水平的正交实验.正交实验结果表明最佳方案为7min、50μmol/L、25℃.第二部分确定研究APTT的抑制效果是否受pH的影响,结果表明APTT时测定的Abs值小,说明APTT的效果比此pH条件的抑制效果好.并且在PH6.5时抑制率大,所以在pH6.5时,抑制效果最佳.

Answer 1

Paper points two parts, the first part is determined in a banana in the best tyrosinase absorption peaks 518.5 nm conditions, in the same reaction time, research mol/L, 34 muon mol/L, 38 muon mol/L 42 muon mol/L, 46 muon mol/L, 50 mu of different concentrations of phenyl - 4-3-5 - sulphur amine 1,2,4 - three ketone of banana APTT) paclobutrazol (inhibitory effect of tyrosinase, the results showed that the best role for 50 mu mol/concentration of L. In the optimal concentration of 50 mu mol/L function, determine the optimal effect time for 7min. In the best role mol/L concentration of 50 mu and the best effect time, 7min ℃, 20 ℃ research 25 ℃ and 35 ℃, 30, 40 ℃ conditions of banana APTT inhibitory effect of tyrosinase, the results showed that the best temperature is 20 ℃. For concentration, temperature, respectively for three factors time three level of orthogonal experiment. Orthogonal experimental results show the best solution for 7min, 50 mu mol/L, 25 ℃. The second part to determine whether the APTT inhibitory effect to study the influence of by pH, the results show that when the Abs APTT determination that small, the APTT value than the effect of the inhibition effect good pH conditions. And in PH6.5 inhibition rate, so when PH6.5, inhibit the best effect
