A reverse-phase high-performance liquid chromatography (HPLC) method was developed for the quantitative analyses of its major constituents rutin, quercetin, and isorhamnetin. In order to develop effective mobile phases, various solvent systems were tested, including acetonitrile, methanol and different combinations of water with phosphoric acid.
Thus, Modes②and③ can greatly increase the effective collision power of the ball mill system, but the groups number of blades and blade-mill volume ratio should be set to exceed the critical value. In order to study the specific value of the critical value, the surface graph of the three were converted into contour maps, as shown in the Fig. 10.
