Embodiment 1
[0087] Embodiment 1: detection method
[0088] 1. Preparation of standard solution and internal standard solution
[0089] 1.1 Preparation of standard series solutions
[0090] Weigh an appropriate amount of the standard substance to be tested, weigh it accurately, add 70% methanol water to make a solution with a concentration of 500 μg / mL, and use it as the stock solution of each sample to be tested. Accurately measure the appropriate amount of each stock solution of the analyte, and use 70% methanol water to prepare tetrasaccharide (concentration is about 70000ng / mL), sucrose (concentration is about 50000ng / mL), salvianolic acid B (concentration is about 12000ng / mL) mL), ginsenoside Rg 1 (concentration is about 8000ng / mL), glucose (concentration is about 6000ng / mL), trisaccharide, ginsenoside Rb 1 , Ginsenoside Rd (concentration is about 4000ng / mL), pyroglutamic acid, rosmarinic acid, notoginsenoside R 1 (concentration of about 2000ng / mL) and the rest of the analyte (con...
Embodiment 2
[0105] The assay of embodiment 2 31 kinds of compositions
[0106] 1. Preparation of sample solution for test
[0107] Compound Danshen extracts S01-S05 (batch numbers 20131205, 20141103, 20120201, 20150310 and 20150310) were provided by Tasly Pharmaceutical Group Co., Ltd.; Danshen medicinal materials S06-S27 were collected from several provinces in China, and Panax notoginseng medicinal materials S28-S52 were collected from Yunnan Province, and crushed at the Tasly Research Institute.
[0108] Take 0.10 g of compound Danshen extract, Danshen extract, Panax notoginseng extract, Danshen powder and Panax notoginseng powder, weigh them accurately, add 10 mL of 70% methanol, sonicate for 30 min, centrifuge for 10 min (16,000 rpm), filter through 0.22 μm Membrane, respectively accurately measure the same amount of sample solution and IS reference solution, and mix them to prepare the sample solution containing internal standard for RP-HILIC-MS / MS analysis. All solutions were sto...
