This method was based on that vitamin K3 was reduced at a glassy carbon electrode, and its product with characteristic fluorescence at 420 nm was determined with excitation wavelength at 309 nm. Under optimized electrochemical reaction conditions and fluorescent experiment parameters, the fluorescence intensity was proportional to the concentration of vitamin K3 in a range from 3.50×10^-7 to 1.05×10^-5 mol/L with a correlation coefficient of 0.9991, and detection limit was estimated to be 7.50× 10^-8 mol/L at a signal/noise ra- tio of 3. The relative standard deviation was less than 4.3%（n=5） and the recovery was in a range of 97%-105% for the determination of vitamin K3 in pharmaceutical preparations. The result is satisfactory for the determination of vitamin K3 as comparison to that from HPLC method.展开更多

Primary dysmenorrhea, acute or chronic pelvic inflammatory disease, endometriosis, post-operational pelvic adhesion, blood stagnation of pelvic vein, etc. , are mentioned as the often encountered causes of pelvic pain. It has been reported in the recent ten or more years that intramuscular injection of vitamin K3 (Vit K3) could relieve pain induced by smooth muscle spasm. In order to evaluate the effect of Vit K3 administered by acupoint injection in relieving pelvic pain, 180 patients were treated and observed from April 1997 to April 1999 in our hospital, and good therapeutic effect was obtained. It was reported as follows.展开更多
A high performance liquid chromatographic method for the simultaneous determination of four fat soluble vitamins: retinol (vitamin A), cholecalciferol(vitamin D), tocopherol(vitamin E) and phylloquinone(vitamin K_1) i...A high performance liquid chromatographic method for the simultaneous determination of four fat soluble vitamins: retinol (vitamin A), cholecalciferol(vitamin D), tocopherol(vitamin E) and phylloquinone(vitamin K_1) in fortified milk powders and egg yolk has been developed. The method requires enzymatic hydrolysis of lipid component of the sample as a pretreatment. Several factors which influence the enzymatic hydrolysis were studied-Separation was achieved using μ-Bondapak C-18 column(3.9×300mm), 98% methanol as mobile phase, a double channel detection was selected; vitamins D_3 E_1 K_1 were detected by UV spectrophotometry (265 nm) first, then vitamin A by fluorometry (EX 325nm, EM 480mm). The retention times of vitamin A_1 D_3, E and K_1 4.87, 9.00, 10.58 and 15.45 min respectively. Detection limit were 0.64, 0.25, 0.50 and 0.07 ng; and the recoveries were 90.5%～103.6% 90.0%～95.6%, 91.7%～98.8%, 91.5%～98.6%, respectively. The vitamins A, D_0, E, K_1 contents in foods were determined satisfactorily.展开更多
