Embodiment 1
[0047] A method for assaying the content of Panax notoginseng in musk promoting blood circulation and removing blood stasis ointment, which is specifically determined according to the following steps:
[0048] The preparation of the test solution takes a size of 7 × 10cm 2 / 10 pieces of musk promoting blood circulation and removing blood stasis ointment (batch number 20130701) per piece, remove the cover lining, accurately weigh, the mass is 23.4603g, cut into pieces, mix evenly, accurately weigh 7.0381g equivalent to the weight of three pieces, and separate the liquid Add 50ml of ether to the funnel, soak for 10 minutes, shake fully to dissolve the ointment, accurately add 50ml of water, shake fully, let it stand, separate the water, wash with ether twice, 15ml each time, discard the ether, water The solution is filtered with dry filter paper, and the filtrate is taken to obtain the final product;
[0049] Preparation of reference substance solution Accurately weigh ginseno...
Embodiment 2
[0076] The size is 7×10cm 2 / Each tablet of musk promoting blood circulation and removing blood stasis ointment (batch number: 20130801) is several pieces, remove the cover lining, accurately weigh, cut into pieces, mix evenly, accurately weigh 6.1616g, which is equivalent to 3 pieces, and prepare according to Example 1 for supply Test solution and reference solution, inertsil ODS-SP (5μm, 250×4.6mm) for the chromatographic column, and other chromatographic conditions are the same as in Example 1, and are measured and calculated according to the method described in Example 1. Measured Rg in the test solution 1 , Rb 1 and R 1 The peak areas are respectively: 479.1, 200.6, 84.5; Rg in the control solution 1 , Rb 1 and R 1 The peak areas are still respectively: 514.2, 178.4, 122.6.
[0077] Calculated: the content of Panax notoginseng in each tablet of Musk Huoxue Huayu Ointment (in Rg 1 , Rb 1 and R 1 The total amount) is: 2.42mg.
Embodiment 3
[0079] Get musk promoting blood circulation and removing blood stasis ointment (lot number: 20130802), accurately weigh the quality that is equivalent to 3 pieces and be 6.2865g, operate and calculate by embodiment 1 step, record Rg in the need testing solution 1 , Rb 1 and R 1 The peak areas are respectively: 332.5, 144.4, 55.9; Rg in the control solution 1 , Rb 1 and R 1 The peak areas are still respectively: 514.2, 178.4, 122.6.
[0080] Calculation: the content of Panax notoginseng in each tablet of Musk Huoxue Huayu Ointment (in Rg 1 , Rb 1 and R 1 The total amount) is: 1.69mg.
