摘要
酪氨酸酶是生物合成黑素的主要酶。降香有促进酪氨酸酶活性的作用。通过对中药降香的水提取液和乙醇提取液促进酪氨酸酶活性作用的观察研究及降香提高酪氨酸酶活性的动力学观察研究,得到Lineweaver-Burk曲线、动力学回归方程及米氏常数Km值。为研究中药有效成分激活黑素细胞的机理奠定了基础。
Tyrosinase is a major enzyme for diosynthesis of melanin.Chinese medicinal herb Dalbergia odorifera T.Chen has the function of stimulating the activity of tyrosine.In the experiment,Lineweaver-Burk curve,Km value,vmax and kinetic regression equation was obtained by testing on Dalbergia odorifera T.Chen s water extract and alcohol extract which speed up tyrosine s activity,and kinetics study of the activity enhancing of tyrosine.This will afford the basis for further study on the mechanism of the activation of melanocyte.
