ABSTRACT

Objective:To study the quality evaluation method of Cyperi Rhizoma processed with four excipients. Method:Ultra-performance liquid chromatography (UPLC) fingerprints of raw products and processed products with four excipients of Cyperi Rhizoma were established, and the changes of chemical components in the fingerprints before and after processing were compared by chemometric analysis. The mobile phase was consisted of methanol (A)-water (B) for gradient elution (0-10 min, 5%-40%A; 10-30 min, 40%-70%A; 30-40 min, 70%A) at a flow rate of 0.3 mL·min<sup>-1</sup>. The injection volume was 3 μL, the column temperature was 35 ℃, and the detection wavelength was 280 nm. The content changes of main index components in Cyperi Rhizoma before and after processing were compared by UPLC. The mobile phase was methanol-water (75∶25) and the detection wavelength was 242 nm. Result:Processing with four excipients had a significant impact on the overall characteristics of chemical components in the fingerprint of Cyperi Rhizoma. A total of 28 characteristic peaks were identified in fingerprints of the raw and processed products. Among them, peaks 1, 2 and 4 were specific peaks of the processed products, peak 5 was characteristic peak of the raw products. Peak 2 was identified as 5-hydroxymethylfurfural, peak 24 as cyperenone and peak 27 as <italic>α</italic>-cyperone. The 5-hydroxymethylfurfural produced by the processing with four excipients came from rice vinegar, rice wine and Maillard reaction of polysaccharides in Cyperi Rhizoma. The results of determination showed that there was no significant difference in the content of cyperenone after processing, but the content of <italic>α</italic>-cyperone decreased significantly. Conclusion:In the process of Cyperi Rhizoma processed with four excipients, there are new components produced by structural transformation, which are accompanied by changes in the content of index components. In this study, the quality of raw and processed products of Cyperi Rhizoma can be rapidly and effectively evaluated from qualitative and quantitative aspects.

ABSTRACT

Objective:To establish the ultra-performance liquid chromatography (UPLC) fingerprints of Artemisiae Argyi Folium and Artemisiae Argyi Folium processed with four excipients, and quantitatively analyze the 8 phenolic acids and flavonoids contained in them, in order to explore the quality evaluation method of Artemisiae Argyi Folium processed with four excipients. Method:UPLC was used with Shim-pack XR-ODS C<sub>18</sub> column (2.0 mm×75 mm, 2.2 µm), mobile phase of acetonitrile (A) -0.2% formic acid aqueous solution (B) for gradient elution (0-1 min, 10%A; 1-2 min, 10%-15%A; 2-17 min, 15%-18%A; 17-24 min, 18%-28%A; 24-36 min, 28%-38%A; 36-41 min, 38%-60%A; 41-45 min, 60%-100%A), detection wavelength of 330 nm and flow rate of 0.2 mL·min<sup>-1</sup>. The UPLC fingerprints of Artemisiae Argyi Folium before and after processing were established, and analyzed by chemometrics. Contents of 5-caffeoylquinic acid, 3-caffeoylquinic acid, 4-caffeoylquinic acid, 3,4-dicaffeoylquinic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid, jaceosidin and epuatilin in the decoction pieces were determined. Result:The fingerprints of Artemisiae Argyi Folium before and after processing were established, and the UPLC characteristic chromatograms of Artemisiae Argyi Folium before and after processing had good consistency, and the similarity was >0.94. Compared with Artemisiae Argyi Folium, the contents of 3-caffeoylquinic acid and 3,4-dicaffeoylquinic acid had no significant change after processing, the contents of jaceosidin and epuatilin decreased after processing, while the contents of 5-caffeoylquinic acid, 4-caffeoylquinic acid and 4,5-dicaffeoylquinic acid increased significantly (<italic>P<</italic>0.01), their average increasing rates were 32.50%, 66.83%, 29.39%, respectively. And content of 3,5-dicaffeoylquinic acid was significantly decreased (<italic>P<</italic>0.01) , and the average reduction rate was 51.25%. Conclusion:The contents of chemical components in Artemisiae Argyi Folium and Artemisiae Argyi Folium processed with four excipients have changed to a certain extent. Among them, 5-caffeoylquinic acid, 3,5-dicaffeoylquinic acid, 4-caffeoylquinic acid and 4,5-dicaffeoylquinic acid can be used as the key indicators for quality evaluation of Artemisiae Argyi Folium before and after processing.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical significance of full volume real-time three-dimensional echocardiography (RT-3DE) in the assessment of general and local systolic functions of the left ventricle in children with Kawasaki disease (KD).</p><p><b>METHODS</b>A total of 73 KD children (40 with and 33 without coronary artery lesions) and 35 healthy control children were recruited. Left ventricular ejection fraction (LVEF) was measured by M-mode ultrasound and full volume RT-3DE imaging. A left ventricular volume-time curve and a segmental speed-time curve were generated. Differences between control subjects and patients with and without coronary artery lesions were analyzed.</p><p><b>RESULTS</b>The M-mode ultrasound measurements of LVEF in KD patients with coronary artery lesions were significantly lower than in KD patients without coronary artery lesions and control children (P<0.05), while there was no significant difference between KD patients without coronary artery lesions and control children. RT-3DE measurements of LVEF were significantly different between the three groups analyzed (P<0.05): coronary artery lesion group < no coronary artery lesion group < control group. RT-3DE-based segmental ventricular wall analysis revealed that Tmsv16-SD and Tmsv12-SD in KD patients with coronary artery lesions were significantly higher than other two groups and Tmsv6-SD was also significantly higher than in the normal control group (P<0.05) and that Tmsv16-SD in KD patients without coronary artery lesions increased significantly compared with the normal control group (P<0.05).</p><p><b>CONCLUSIONS</b>RT-3DE can be used in the quantitative evaluation of the left ventricular function and therefore has significant clinical implications.</p>
