Quality Criteria of Lianqi Bushen Capsule / 中国药房

OBJECTIVE:To establish the quality standard of Lianqi bushen capsule.METHODS: TLC was employed to identify Panax ginseng in Lianqi bushen capsule,while the content of trigonelline was determined by RP-HPLC.The determination was performed on Kromasil C18(150 mm?4.6 mm,5 ?m)column and mobile phase consisted of methanol-0.05%sodium dodecyl sulfonate-acetic acid(20 ∶ 80 ∶ 0.1)with flow rate of 1 mL?min-1.The detection wavelength was set at 265 nm and column temperature was set at 30 ℃.RESULTS:P.ginseng can be identified by TLC.The linear range of trigonelline was 10～200 ?g?mL-1(r=0.999 9) and average recovery was 98.86%(RSD=1.4%,n=5).CONCLUSION:The standard is used for the quality control of Lianqi bushen capsule.
