ABSTRACT
Objective: To establish a method for the determination of gastrodine in Tianma Formula Granule. Methods: HPLC was used with LiChrospherR 100 column, MeOH-phosphate solution(contain KH2PO4 and Na2HPO4 each 0.1mol/L)-water(1.5:3:95.5) as mobile phase and detection wavelength at 270nm. Results: Gastrodine showed a good linearity in the range of 1.638～14.742?g. The average recovery was 98.17 %and RSD was 1.39 %(n=5). Conclusion: This method is simple, accurate and with good reproducibility, and can be used for the quality control of Tianma Formula Granule.
ABSTRACT
Objective: To establish a method for determinating icarin content in Naoling Granule. Methods: Water-soluble ethyl-acetate-extracting polyamide column purification was adopted. The content of icarin was determined by HPLC. C18 column was used, mobile phase was methanol:0.1mol/mL sodium phosphate dibasic (6:5) and detection wavelength was at 270nm. Results: Icarin has a good linearity in the range of 0.24～1.2?g ( r=0.9998). The average recovery was 98.23 %and RSD was 1.2 %(N=5). Conclusion: The method was simple with good reproducibility and can be used for the content determination of icarin in Naoling Granule.
ABSTRACT
Objective To establish a method for the Determination of Danshensu content in Tongmai Capsules. Methods The content of Danshensu was determined by HPLC on Kromasil C18 Column( 4.6? 250 mm, 5 ? m) . The mobile phase was acetonitri1- 1.2 % water solution of acetic acid (9∶ 91) and the detection wavelength was 280 nm. The theoretical plates should over 3000 according to Danshensu. Results Sodium Danshensu showed a good linearity in the range of 0.288～ 1.152 ? g, r=0.9994. The average recovery was 97.62 % , and RSD was 1.10 % (n=5). Conclusion This method is effective and can be used for the quality control of Danshensu in Tongmai Capsules.
ABSTRACT
Objective To compare the effects of two crushing methods on dissolution rate and decocting rate of water-soluble protein in Plastrum Testudinis.Methods The dissolution rate of water-soluble protein was compared in Plastrum Testudinis processed by the traditional crushing method(passing 100-eyes screen,fine powder)and ultra-fine crushing method(passing 300-eye screen,ultra-fine powder);besides,orthogonal design was applied to study the process technical condition of decocting rate in Plastrum Testudinis.Results Water-soluble protein in fine powder of Plastrum Testudinis was hardly detected while the dissolution rate of water-soluble protein in ultra-fine powder was 51.2 %in 20 minutes and up to 70.5 %at 2 hours.Three influencing factors of fineness,decocting frequencies and decocting time were measured with orthogonal test.The results of variance analysis showed that fineness significantly influenced the decocting rate(P .05).Conclusion The ultra-fine powder technique is propitious to the increase of dissolution rate and decocting rate of water-soluble protein in Plastrum Testudinis.
ABSTRACT
Objective To establish a method for the determination of hesperidin content in Qiansheng Baizhusan Jiawei Granule (QBJG). Methods The content of hesperidin was determined by HPLC. Results Hesperidin showed a good linearity in the range of 0. 22-1.1ug(r = 0. 9998). The average recovery was 103. 0 % and RSD was 3. 12 %. Conclusion The methods are accurate and can be used for the quality control of QBJG.
ABSTRACT
AIM: To establish the quality standards for Fukang Capsules(Cortex Phellodendri Chinensis,Cortex Ailanthi,Fructus Schisandrae Chinensis,etc.). METHODS: Cortex Ailanthi,Fructus Schisandrae,Poria were identified by TLC,and the content of berberine hydrochloride was determined by TLC-scanning. RESULTS: Cortex Ailanthi,Fructus Schisandrae,Poria could be identified by TLC.Berberine hydrochloride showed a good linear relationship at a range of 25.32 ng-354.48 ng,r=0.993 28.The average recovery was 100.3%,and RSD was 2.04%. CONCLUSION: The method is accurate and can be used for the quality control of Fukang Capsules.
ABSTRACT
Objective: To establish the quality standard for Guangxiao Liniao Capsules (Herba Verbenae, Herba Leonuri, Rhizoma Alismatis, Radix Linderae, etc.). Methods: Herba Verbenae, Herba Leonuri, Rhizoma Alismatis, Radix Linderae were identified by TLC, and the content of stachydrine hydrochloride was determined by TLC scanning. Results: Herba Verbenae, Herba Leonuri, Rhizoma Alismatis, Radix Linderae could be identified by TLC. Stachydrine hydrochloride showed a good linear relationship at a range of 4?g～20?g, r = 0.9975. The average recovery was 97.9%, and RSD was 1.20%. Conclusion: The methods are accurate and can be used for the quality control of Guangxiao Liniao Capsules
