RESUMO
<p><b>OBJECTIVE</b>To investigate the anti-HIV constituents from the root of Mirabilis jalapa.</p><p><b>METHOD</b>The compounds were isolated by column chromatography on silica gel, Sephadex LH - 20, MCI-gel CHP-20P and RP-18. The structure were identified by means of NMR and MS analyses (1H-NMR, 13C-NMR, MS).</p><p><b>RESULT</b>Eleven compounds were isolated and identified as astragaloside II (1), astragaloside II (2), astragaloside IV (3), astragaloside VI (4), flazin (5), 4'-hydroxy-2, 3-dihydroflavone 7-beta-D-glucopyranoside (6), gingerglycolipid A (7), 3, 4-dihydroxybenzaldehyd (8), p-hydroxybenzaldehyde (9), beta-sitosterol (10) and daucosterol (11).</p><p><b>CONCLUSION</b>Compounds 1-9 were obtained from this genus for the first time.</p>

<p><b>OBJECTIVE</b>To develop an HPLC method for the measurement of flavones in Elsholtzia bodinieri.</p><p><b>METHOD</b>Analysis was carried out on Shimadzu LC-2010A HPLC system. The separation was performed on Agilent Extend-RP C18 column (4. 6 mm x 250 mm, 5 microm), with methanol-acetonitrile-0.2% phosphoric acid as mobile phase, and the flow rate was 1.0 mL min(-1) and the detective wavelength was 280 nm.</p><p><b>RESULT</b>A good linear relationship and the mean recovery was found within the range.</p><p><b>CONCLUSION</b>This method is rapid, simple and accurate.</p>
