Based on summarizing the international experiences and reviewing the historical evolution and current situation of the physicians'compensation system of public hospitals in China,this paper clarified the existing problems of the current compensation system.Such problems namely included lack of security on the source of the physicians'compensation,low level of sunshine salary which caused thecompensatory mechanism,lack of scientific design of the salary structure and allocation,as well as other underlying causes.Drawing lessons from reform practices at home and abroad,the basic principles and reform directions were put forward,as well as 4 route selections,namely establishing an security investment system to guarantee a stable and higher level salary under the current compensation system, implementing a high level of flip-type annual compensation with locking the current salary into files, establishing an appropriate compensation system referring to an innovated evaluation system of physicians in public hospitals,and coordinating closely with public institution reforms to promote physicians' compensation system reform.

OBJECTIVETo develop an HPLC method for simultaneous determination of rutin, hyperoside, quercetin and kaempferol in Malus prunifolia from Shanxi province in China.

METHODThe separation was performed on a Hypersil C18 column (4.6 mm x 250 mm, 5 microm), using a gradient elution with methanol-water containing 0.2% phosphoric acid as the mobile phase. The flow rate was 1.0 mL x min(-1), the detection wavelength was 360 nm and the temperature of column was 25 degrees T.

RESULTThe linear ranges of rutin, hyperoside, quercetin and kaempferol were 1.87-46.67 mg x L(-1), 6.40-160.0 mg x L(-1), 3.33-83.33 mg x L(-1), 0.80-20.00 mg x L(-1), respectively. The average recoveries (n=6) of the four constituents were 99.2% (RSD 2.9%), 98.2% (RSD 1.9%), 97.4% (RSD 2.3%), 97.2% (RSD 1.3%), respectively.

CONCLUSIONThe method was simple, accurate and can be used to evaluate medicinal value of Malus prunifolia.
