查询词典 succedanea

In this study, alkylhydroquinone, 10'-heptadecenylhydroquinone [HQ17(1)], isolated from the sap of the lacquer tree Rhus succedanea, was found to inhibit the activity of tyrosinase and to suppress melanin production in animal cells.

在之前的研究中，我们已经由漆树Rhus succedanea的漆液中萃取纯化得到的一个对苯二酚衍生物，此衍生物在第二个碳的位置有17个碳的不饱和碳链，根据其化学结构命名为10′–heptadecenylhydroquinone，并简称为HQ17(1)。

This article makes a study of the effects of six different solvents on lacquer wax extraction of the Japanese Rhus succedanea,concerning the rate of extraction,the albedo value,melting point and chemical characteristics.

研究6种不同溶剂对日本野漆蜡的萃取率、白度值、熔点和化学特征值的影响。结果表明，溶剂种类对日本野漆蜡萃取率和白度值具显著性影响，但对熔点和化学特征值影响较小。试验得出石油醚(30~60℃)是漆蜡萃取的最佳溶剂，浸提温度低，时间短，漆蜡萃取率高，产品白度值高、色泽好，操作过程安全

This matter overthrew all basises I learned from Sunday school .
