Title: Study On Quality Standard of Lingwu Granules
Abstract: Objective To establish a quality standard for Lingwu granules.Methods Ganoderma,Schisandrae Chinensis Fructus and Bupleuri Radix were identified by TLC.Agilent HC-C18(150 mm×4.6 mm,5 μm) was used as the stationary phase,with methanol-water(52∶ 48) as mobile phase.The photodiode array detector was set at 250 nm.Column temperature was set at 40 ℃.Results Spots on TLC were clear without interference.The calibration curve was linear over the range of 0.049 36-1.234 mg(r=1).The average recovery of the method was 99.41%.RSD was 1.40%(n=6).Conclusion This method is reliable and accurate,able to separate and determine paeoniflorin in Lingwu granules.
