[Influence of leaf-picking on effective constituents of the Astragalus mongholicus roots].
After the application of the orthogonal design, experiments show that the proportion and time of leaf-picking have a great influence not only on the total content of 17 kinds of amino acids but also on that of Astragaloside. If the proportion is large and the time is delated, both contents of 17 kinds of amino acids and Astragaloside will be reduced accordingly compared to the control group. There is less influence on the contents if the time of leaf-picking is set on June 15 each year and the picking proportion is 1 out 3.
