A method for simultaneous determination of the shikonin, acetyl shikonin and β, β'-dimethylpropene shikonin in Onosma hookeri and the chromatographic fingerprint was estabished by HPLC-DAD on an Agilent Zorbax SB-column with a gradient elution of acetonitrile and water at 0.8 mL x min(-1), 30 degrees C. The quality assessment was conducted by comparing the content difference of three naphthoquinone constituents, in combination with chromatographic fingerprint analysis and systems cluster analysis among 7 batches of radix O. hookeri. The content of the three naphthoquinone constituents showed wide variations in 7 bathces. The similarity value of the fingerprints of sample 5, 6 and 7 was above 0.99, sample 2 and 3 above 0.97, sample 3 and 4 above 0.90, and other samples larger than 0.8, which was in concert with the content of three naphthoquinone constituents. The 7 samples were roughly divided into 4 categories. The results above indicated that the using of this medicine is complex and rather spotty. The established HPLC fingerprints and the quantitative analysis method can be used efficiently for quality assessment of O. hookeri.

<p><b>OBJECTIVE</b>To explore the effects of traditional Tibetan medicine, Fructus Lonicerae microphyllae (FLM) on phagecytosis and cytokines production of murine macrophages.</p><p><b>METHOD</b>The phagecytosis of murine macrophages was analyzed by neutral red phagecytosis assay. The activities of IL-1 and TNF-alpha were measured by biological methods. The mRNA of TNF-alpha and INF-gamma expressed by macrophages was detected by RT-PCR.</p><p><b>RESULT</b>The phagecytosis of murine macrophages was significantly enhanced by FLM at a concentration from 1 microg x mL(-1) to 100 microg x mL(-1) and the secretions of IL-1, and TNF-alpha from macrophages were markedly induced by FLM. Meanwhile, FLM also increased the expression of TNF-alpha mRNA and INF-gamma mRHA from macrophages in vitro.</p><p><b>CONCLUSION</b>FLM could promote phagecytosis and cytokines production of murine macrophages.</p>
