ABSTRACT
Objective To establish a UPLC-Q-TOF-MSE fingerprint of Yiqi Fumai Injection (YQFM) for providing reference for visual, easy and overall control of its quality. Methods The chromatographic separation was performed on a Waters Acquity UPLC HSS T3 (100 mm × 2.1 mm, 1.8 μm) column with the mobile phase consisting of acetonitrile and 0.1% formic acid for gradient elution. The flow rate was 0.3 mL/min, and the column temperature was 30 ℃. The capillary voltage was set at 2.5 kV. The nebulization gas was set to 800 L/h at 400 ℃, and the source temperature was 100 ℃. The BPC obtained with negative ion ESI mass spectra were selected for the fingerprint analysis. Similarity evaluation was used to evaluate the quality of YQFM from different batches. Based on the intensities of the ions for common peaks, HCA and PCA were performed using SPSS 19.0 and Simca-P software. Results The UPLC-Q-TOF-MSE fingerprint of YQFM was established by using 28 batches of sample and 18 common peaks were found, of which 15 mutual peaks from Ginseng Radix et Rhizoma rubra, three mutual peaks from Ophiopogonis Radix. Compared with the reference substances and references, 16 of the common peaks were identified and the similarity of 28 batches samples were over 0.970. 28 batches of YQFM could be divided into four grades when the sum of squared Euclidean distance is 5-10 in the result of HCA; PCA got seven principal components through dimension reduction and accumulative contribution rate reached 84.989%. By fitting the load factor model of the first principal component, ten markers greatly impacting on the quality were found. The comprehensive evaluation function of YQFM in different batches was constructed according to the principal component score. Among 28 batches of YQFM, the comprehensive score of S28 was the best, closely followed by S22, S11 and S9, while S14 and S13 was the worst. Conclusion The utilization of UPLC-Q-TOF-MSE fingerprint coupled with chemical pattern recognition could objectively and effectively assess the quality of YQFM, can provide a more comprehensive reference for the quality control of YQFM.
ABSTRACT
Objective To establish a quantitative analysis of multi-components with a single-marker (QAMS) method for the determination of nine components in Yiqi Fumai Injection (YFI). Methods Ginsenoside Rb1 was used as internal reference substance. The relative correlation factors (f) of ginsenosides Rg1, Re, Rf, Rc, Ro, Rb2, Rd, and schisandrin were calculated and established by HPLC. The separation was performed on a Diamonsil® C18 column (2) (250 mm × 4.6 mm, 5 μm), with the mobile phase consisting of acetonitrile and 0.05% phosphoric acid water for gradient elution. The column temperature was 30 ℃, and the detection wavelength was set at 203 nm, flow rate was 1 mL/min. The results were compared with those obtained by the external standard method in 25 batches of YFI. Results Ginsenosides Rg1, Re, Rf, Rb1, Rc, Ro, Rb2, Rd, and schisandrin had good relations within the ranges of 0.929-4.644, 0.818-4.089, 0.732-3.660, 1.461-7.305, 0.636-3.181, 0.618-3.092, 0.788-3.941, 0.758-3.789, and 0.178-0.889 μg, respectively. The recovery rates were 97.08%-100.94%. The f values of ginsenosides Rg1, Re, Rf, Rc, Ro, Rb2, Rd, and schisandrin to ginsenoside Rb1 were 1.970, 0.929, 1.196, 0.870, 0.830, 0.786, 0.906, and 12.082. The two methods did not show the significant difference in assay results. Conclusion The QAMS method is feasible and credible, and could be used to determine the multiple components in YFI.
ABSTRACT
Objective To observe the therapeutic effect ofYiqi-Fumai injection andShenshao capsule in the treatment of angina pectoris and the influence on vascular endothelial cell function and serum MPO. Methods 90 cases of angina pectoris of coronary heart disease were randomly divided into a treatment group and a control group. 50 cases in the treatment group were treated withYiqi-Fumai injection and Shenshao capsule; 40 cases in the control group were treated with Plavix and metoprolol; clinical symptoms were observed before and after treatment, the indexes of endothelial cell function and electrocardiogram blood serum nitric oxide (NO), endothelin (ET), NOS and serum MPO, SOD, GSH changes were compared.Results The content of nitric oxide (NO), 6-keto-PGFLa and NOS of the treatment group were increased than the control group, while ET was reduced. In the treatment group, NO was (78.09 ± 88.71)μmol/L 6-keto-PGFL was 32.04 ± 25.82 pg/ml and NOS was 27.88 ± 9.08 U/MI before the treatment,; after the treatment, the NO was 127.11 ± 103.60μmol/L, 6-keto-PGFLa was 50.03 ± 60.87 pg/ml and NOS was 35.12 ± 22.18 U/MI. In the control group, NO was 96.98 ± 82.45μmol/L, 6-keto-PGFLa was 40.31 ± 51.92 pg/ml and NOS was 28.12 ± 5.11 U/MI before the treatment; After the treatment, NO was 95.62 ± 6.31μmol/L, 6-keto-PGFLa was 29.09 ± 42.01 pg/ml and NOS was 30.11 ± 7.51 U/MI. In the treatment group, ET was 58.81 ± 33.18 pg/ml before the treatment and 42.47 ± 40.5 pg/ml. after the treatment.
