ABSTRACT
This project was launched to and establish the wavelength overlapping HPLC fingerprint for Danshen and determine the contents of 7 component in Danshen. The chromatographic fingerprints were built by using Agilent Eclipse Plus C_(18)( 4. 6 mm×100 mm,3. 5 μm) as stationary phase and 0. 1% formic acid solution( A)-acetonitrile( B) as mobile phase with gradient elution( 0-5 min,10%-20% B; 5-20 min,20%-30% B; 20-25 min,30%-50% B; 25-40 min,50%-65% B; 40-45 min,65%-80% B; 45-46 min,80%-10% B; 46-50 min,10% B) at a flow rate of 1 mL·min~(-1). The column temperature was maintained at 30 ℃ and the detection wavelength was set at 250,280,310 and 340 nm. The technique of wavelength overlapping fingerprint was established and the contents of 7 indicative compounds have been determined in this method. The results of wavelength overlapping HPLC fingerprint showed all-around information of the fingerprints at 250,280,310 and 340 nm,and the similarity among 17 batches of Danshen was over 0. 828-0. 936. In wavelength overlapping HPLC fingerprint,15 common peaks were selected as the common peaks,and 7 contents of them were indentified as rosmarinic acid,salvianolic acid B,salvianolic acid A,phenolic acid,dihydrotanshinone Ⅰ,tanshinone Ⅰ and tanshinone ⅡA. The results of methodological study demonstrated that the method met the requirements of the determination. The method established in this study is simple,convenient and durable,which can provide a scientific basis for the quality control of Danshen.
