Quantitative determination of contents of three components in Brucea javanica by HPLC / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To develop an HPLC method for quantitative determination of three quassinoids in Brucea javanic.</p><p><b>METHOD</b>The determination was carried out on a phenomenex C18 column (4.6 mm x 250 mm, 5 microm) with gradient elution program of methol-water at a flow rate of 1.0 mL x min(-1), and the detection wavelength was 270 nm.</p><p><b>RESULT</b>Linearites of bruceine D, brusatol and bruceine H were good (r = 0.9996, 0.9996, and 0.9998) in ranges of 2.52-12.60, 2.19-10.95, and 2.91-14.55 microg, respectively. The average recoveries of bruceine D, brusatol and bruceine H were 100.01%, 100.95% and 100.43% respectively, and RSD of the above three compounds were 0.31% (n = 6), 1.7% ( n = 6) and 1.7% (n = 6), respectively.</p><p><b>CONCLUSION</b>The determination results of three batch samples showed that the method was simple, accurate and could be used in the quantitative determination of three components in the B. javanica.</p>
