（13∶87∶0.2） as mobile phase，with UV detection at 256 nm.Results Protocatechuic acid has better linear correlation between 0.103 μg and 0.7725 μg，the results also have shown the recovery rate was 97.76%，RSD 1.01%.Conclusion The methods is very stable and accurate，and has good reappearance.It can be used for quality control of Fuxuekang Jiaonang.[Key specific words] RP HPLC, - Protocatechuic acid, Fuxuekang Jiaonang, Search moncler pricelessFu blood by blood kang kang capsule form particle change women come from yunnan, is GuiYiNa incense refined by extracting, made of TCM. Invigorate the menstrual function, hemostatic has the effect. For blood stasis caused by the block menstruation, menstrual extension. In order to fully control the product quality, this paper establish reversed phase high performance liquid chromatography (HPLC) determination moncler jackets RP - blood kang capsule zhongyuan catechin levels, and control the quality of blood kang capsule women, to ensure the clinical curative effect.1 instruments and reagentsJapanese island jele 1.1 instrument LC - 10 highly effective liquid phase color spectrometer, ultraviolet detectors, the SPD - 10AV CT - 100 to the constant temperature box, LC2002 data processing system, CSB6L - 180D moncler vest ultrasonic cleaning device, electronic scales (1-45SM AEG, 10 million).1.2 reagent for chromatographic alcohol, methanol, pure water for analysis of phosphate as distilled water. Protocatechuic acid (China pharmaceutical and biological products shall, 200102 batch 809 -). Fu blood kang capsule (provide) product development.Two methods and results2.1 chromatography column: (1) the silica column (TM) Diamonsil C18 (2.5 x 4.6 mm, 5 m) moncler coats (DiMa company speeds. (2) as mobile phase: water, methanol phosphate (13:87:0.2). (3) : 256nm detected wavelength. (4) velocity: 1.0 ml/min. (5) : 40 degrees oven temperature.The preparation of 2.2 reference solution precision says activitely phosphorus dry 12 h protocatechuic acid products made with methanol, respectively 0.0412 mg per 1 ml contain 0.0515 mg of solution, and accordingly.The preparation of the Cheap Moncler 2.3 solution women take blood kang, the capsule 10 content, research, said, take fine powder about 1.8 g, precision said, adding 20 ml, ultrasonic extraction 20 min left to dissolve, cold, filtration, filtrate and 0.5 ml hydrochloric acid, using ethyl ether vibration wave extraction 4 times, each time 30 ml, merger, ether, scraps of methanol solution with top 10 ml Discount Moncler dissolved and transferred to LiangPing, methanol diluted to scale, shake, accordingly.The preparation of negative control solution 2.4 percentage prescription, according to weigh dextrin woman preparation technology of blood kang capsule and preparation methods of the solution were negative control solution.The linear relationship between 2.5 respectively precision drain protocatechuic acid solution (controlled) 2 0.0515 mg/ml, 2.5 muon muon l l, 5 Moncler Outlet muon l, 10 mu l, 15 mu l, liquid chromatography, determination, protocatechuic acid into samples (g), for HengZuoBiao speeds for peak area, including integral value standard curve. Regression equations for X = 6E + 6 inclined + 11494 (r = 0.9998). Results show that protocatechuic acid in 0.103 ~ 0.7725 muon g range has good linear relationship.2.6 precision experiments precision Moncler Sale drain protocatechuic acid solution (controlled) 0.0412 mg/ml, repeat 10 mu l in 5 times, peak area respectively, and points 2539158 2507078, 2501244, 2530911, 2472997, RSD = 1.04%. This method shows good precision.Take the same 2.7 repetitive experimental blood kang capsule (women), 050804 batch: the content, fine, fine powder, each about 1.8 5 g, precision said, according to the preparation method
