Estimation of effects of liuwei Dihuang Wan on anti-inflammation in rat by HPLC-UV based metabonomic method / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To understand the possibility of estimating the anti-inflammation effect of Liuwei Dihuang Wan (LWW) in rat by having developed HPLC-UV metabonomic technology.</p><p><b>METHOD</b>The hydrophilic or lipophilic constituent group of LWW was extracted by distilled water or acetic ether respectively. The anti-inflammation effects of different LWW dosages and extractions were measured by traditional method respectively. Then, metabonomic analysis was performed.</p><p><b>RESULT</b>The high dosage of LWW extraction (16.5 g x kg(-1))could inhibit the swell of rat palm significantly, but there are not statistically significant effect of low dosage group. Nevertheless, the metabonomic study showed that LWW extraction could restore obviously the rat HPLC-UV urinary profiling disturbed by inflammation in low dosage, especially the hydrophilic constituent group.</p><p><b>CONCLUSION</b>Our study indicated that the developed metabonomic technology based on HPLC-UV might be used as a potentially powerful tool for estimating the anti-inflammation effect of LWW with sensitivity and integrity.</p>
