Danshen is one of the most frequently used traditional Chinese herbs owing to its remarkable and reliable therapeutic effects. Phenolic acids and diterpenoids have proved to be the bioactive substance groups. In order to fully profile its chem. compositions and explore new potential bioactive compounds, a comprehensive two-dimensional liquid chromatog. system coupled to DAD detector and hybrid linear ion trap (LTQ) Orbitrap mass spectrometry (LC × LC-DAD-ESI/HRMS/MSn) was set up in this study based on the column combination of Hypersil gold CN (150 mm × 1 mm, 3 μm) and Accucore C18 (50 mm × 4.6 mm, 2.6 μm). Using the optimal segment gradient program, phenolic acids and diterpenoids were separated into two independent groups and a total of 328 peaks were successfully detected on the contour plot of Danshen. By means of the accurate mass and reliable MSn data, 102 compounds were identified or tentatively identified and 7 of them were discovered from Danshen for the first time. Moreover, the LC × LC-DAD system was validated for the quant. anal. of 14 bioactive analytes using the contour plot, exhibiting satisfactory linearity (r ≥ 0.9976) and high precision for both peak locating (≤1.07%) and peak volume calculating (0.34%-4.11%). The established method could afford powerful separation capability, reliable identification data and accurate quant. results, which is very suitable for anal. of complex herbal samples. In the experiment, the researchers used many compounds, for example, (R)-3-(3,4-Dihydroxyphenyl)-1-methoxy-1-oxopropan-2-yl (2S,3S)-2-(3,4-dihydroxyphenyl)-4-((E)-3-(((R)-3-(3,4-dihydroxyphenyl)-1-methoxy-1-oxopropan-2-yl)oxy)-3-oxoprop-1-en-1-yl)-7-hydroxy-2,3-dihydrobenzofuran-3-carboxylate (cas: 875313-64-7SDS of cas: 875313-64-7).

Er Shen Zhenwu Decoction is a prescription for treating chronic heart failure of heart and kidney yang deficiency, while its active ingredients remain unclear and difficult to identify. This paper aims to apply a rapid assay strategy of ultra-high-performance liquid chromatog.-quadrupole time-of-flight mass spectrometry to collect the mass spectrometry data of Er Shen Zhenwu Decoction and its decomposed recipes (monarch, minister, and assist). By comparing with retention time and MSE fragmentation patterns, 67 and 34 components in vitro and in vivo were identified, resp., the main ingredients include saponins, terpenes, alkaloids, phenolic acids, tanshinone, urea, steroids, aromatics, organic acids, carbohydrates, and so forth, of which the monarch medicine > minister medicine > assist medicine. By comparison with reference standards, paeoniflorin, rosmarinic acid, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1 and atractylenolide III were identified in vitro and paeoniflorin, ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1 were identified in vivo. In this study, the chem. ingredients of Er Shen Zhenwu Decoction were analyzed by ultra-high-performance liquid chromatog.-quadrupole time-of-flight mass spectrometry technol. and each compound was grouped into the decomposed recipes. The identified substances can be used as references for Er Shen Zhenwu Decoction quality control and potential medicinal substances in chronic heart failure of heart and kidney yang deficiency treatment.
