ABSTRACT

Objective To develop a HPLC method for determining the contents of lobetyolin and gallic acid in Eighteen Flavors Dangshen Pill(EFDSP) produced by different factories.Methods The HPLC analysis was performed on a VP-DOS C18 column (4.6 mm×150 mm,5 μm).The mobile phase was acetonitrile and 0.4% glacial acetic acid(21∶79) in the determination of lobetyolin content.The detection wavelength was 267 nm and the flow velocity was 1 mL/min.the column temperature was25 ℃ and the sample size was10 μL.The mobile phase was methanol and 0.4% glacial acetic acid(1∶99) in the determination of gallic acid content.The detection wavelength was 280 nm.The column temperature was 25 ℃ and the sample size was 10μL.Results The contents of lobetyolin and gallic acid in EFDSP were 1.0835mg·g-1and 15.334 0 mg/g for Qinghai Gela Dandong Tibetan Pharmaceutical Factory;0.628 9 mg/g and 15.159 5 mg/g for Changdu Tibet Medicine Factory;0.306 5 mg/g and 8.762 7 mg/g for Tibetan Hospital of Tibet.Conclusion This method has the advantages of good reproducibility,good accuracy,simple and fast operation.The contents of lobetyolin and gallic acid in EFDSP produced by different manufacturers are significantly different.The gallic acid content has greater difference.It provides the reference for quality control of EFDSP

ABSTRACT

Objective To observe the left lower limb great saphenous vein double backbone variations and then conclude correlated var -iation with articles and essays which can offer basic data reference for correlational research and treatment .Methods A male adult corpse fixed by 10%formalin was dissected , and the aberrant vessels were measured by digital caliper and Digimizer .Collected essays and articles about variation of great saphenous vein and its tributary on CNKI from January 1,2000 to May 1,2016.Results There were two major vein of left lower limb great saphenous vein from feet to foramen of saphenous vein of this corpse .The common variations of great saphenous vein and its tributary included variation of quantity and position .Conclusion The variations of great saphenous vein and its tributary do not exist alone.There are usually several variants exist together .So,taking an imaging examination before the operation of great saphenous varicose veins is the key of preventing vessels from injury and reducing the happening of complication .
