RESUMO

It's difficult to identify Aucklandiae Radix and Vladimiriae Radix because of their similar composition. In this paper, UPLC method was used to establish their UPLC fingerprint to identify them with the mobile of acetonitrile -0. 05% phosphoric acid water solution by gradient elution at the detection wavelength of 238 nm. Clustering analysis and principal components analysis showed that Vladimiriae Radix was significantly different from Aucklandiae Radix. Eight common peaks and twelve common peaks were defined respectively in Aucklandiae Radix and Vladimiriae Radix herbs by fingerprint analysis. Six of them were identified as syringoside, chlorogenic acid, isochlorogenic acid A, isochlorogenic acid B, costunolide and dehydrocostuslactone by comparing with standard references. There are four peaks in all of Vladimiriae Radix samples and in none of Aucklandiae Radix samples. So UPLC fingerprint can be used to identify these two herbs.

RESUMO

<p><b>OBJECTIVE</b>To establish an HPLC-ELSD fingerprint of the whole herbs of Morina nepalensis and perform the correlation analysis of chemical components of the herb and nitric oxide (NO) production inhibition.</p><p><b>METHOD</b>HPLC-ELSD assay was performed to evaluate 10 batches of M. nepalensis herbs. The chromatographic conditions were as following: Eclipse XDB C18 column (4.6 mm x 150 mm, 5 microm), water (A) and acetonitrile (B) as a gradient mobile phases, flow rate 1.0 mL x min(-1), and column temperature at 35 degress C. Evaporative light-detection conditions: atomization temperature at 104 degrees C, the flow rate of N2 2.8 L x min(-1) and 10 microL sample injection. Chromatographic fingerprint was developed, and the inhibition activity of production of NO in lipopolysaccharide-induced macrophages was also analyzed. The similarity and correlation analysis between the HPLC-ELSD fingerprints and NO production inhibition were carried out by PLS method.</p><p><b>RESULT</b>The common mode for M. nepalensis herb fingerprint was established, including 15 common characteristic peaks. Among them, 7 peaks were positively correlated with the NO production inhibition. According to the assessment on the similarity of 10 batches of samples, a similarity of over 0.90 were shown in HPLC-ELSD fingerprint and all samples were separated into two groups.</p><p><b>CONCLUSION</b>This method can be used to assess the quality of M. nepalensis, which provides a reliable method for scientific assessment and quality control.</p>
