ABSTRACT
<p><b>OBJECTIVE</b>To describe the difference between native and nonative herbs by determining contents of seven kinds of flavone for twenty-five samples from seventeen areas.</p><p><b>METHODS</b>HPLC. Fluid phase MEOH-H2O-CH3COOH(ICE) (41590.2) and (50500.2). Detection wavelength 275.</p><p><b>RESULTS</b>The contents of baicalin are 6%-9%, wogenin are 2%-8%, baicalein are 0.1%-1.6%, neobaicalein are 0.01%-0.2%, wogonin are 0.01%-0.3%, visidulin and oroxylin are trace amounts or undetected.</p><p><b>CONCLUSION</b>The native and nonative herbs have no distinct differce in absolute component ratio. The ratio of baicalin and wogenin is under three. The ratio of baicalin and baicalein, baicalin and wogonin is between twenty and fifty.</p>
