ABSTRACT
Objective: To establish the HPLC fingerprint of Olibanum. Methods: The column was Agilent ZORBAX SBC18(250 mm×4. 6 mm,5 μm) with the mobile phase of acetonitrile-0. 1% phosphoric acid (gradient elution) at a flow rate of 1. 0 ml·min-1, the detection wavelength was 270 nm,the column temperature was 30℃,and the injection volume was 10 μl. Olibanum samples from different regions were detected for the characteristic fingerprint. Similarity evaluation software for chromatographic fingerprint of tradi-tional Chinese medicine (2012 edition) was used for the common peaks identification and similarity evaluation. Results: The HPLC fingerprint analysis method for Olibanum was established. The fingerprint consisted of 10 common peaks. The similarities of the finger-prints of twelve samples from different regions were above 0. 95. Conclusion: The method is simple and rapid with good reproducibili-ty, which provides basis for the quality control and evaluation standard of Olibanum.
ABSTRACT
Aim To explore the differences in hyper-trophic marker genes such as atrial natriuretic peptide ( ANP) , brain natriuretic peptide ( BNP) and β-myo-sin heavy chain (β-MHC) genes in different models of cardiac hypertrophy. Methods Respectively using re-nal abdominal aortic coarctation ( AAC) , arteriovenous fistula ( AVF) and isoproterenol ( ISO) methods to es-tablish C57BL/6 mouse model of cardiac hypertrophy. After modeling, each mouse ’ s body weight ( BW ) , heart weight ( HW) and left ventricular weight ( LVW) were weighed, and the heart weight ( HW/BW) and left ventricular index ( LVW/BW ) were calculated;myocardium by HE staining, pathological morphologi-cal changes were observed; myocardium by immuno-histochemistry, ANP, BNP and β-MHC protein ex-pression was observed;myocardium by Real-time PCR detection, ANP, BNP and β-MHC mRNA expression was observed. Results Compared with control group, HW/BW and LVW/BW were increased in three mod-els. Through the light microscope, each mouse model showed varying degrees of cardiac hypertrophy. ANP, BNP and β-MHC were increased in the protein and mRNA expression. Compared with AAC group, AVF and ISO groups’ myocardial tissue ANP, BNP and β-MHC expression were decreased in the protein and mRNA expression. Conclusions Three cardiac hy-pertrophy models are successful. Cardiac tissue ANP, BNP and β-MHC expression in AAC model exceeds AVF and ISO model.
