Determination of Vitamin C in Small Volumes of Blood by HPLC/EC
A sensitive procedure for determining total vitamin C (ascorbic acid + dehydrate ascorbic Acid) in a blood drop from a finger prick, before and after the adminis- tration of a vitamin C tablet is described. Analysis was carried out by high per- formance liquid chromatography with electrochemical detection (HPLC/EC). Measurements were taken one hour, two hours and six hours after the adm...
متن کاملDetermination of total vitamin C in fruit juices and related products by liquid chromatography: interlaboratory study.
A interlaboratory study was conducted to evaluate a liquid chromatographic (LC) procedure for the determination of total vitamin C in foods at levels of 5-60 mg/100 g. Emphasis was placed on fruit juices, although selected foods were also included in the study. Following dissolution of sample in water, endogenous dehydroascorbic acid was converted to ascorbic acid by precolumn reduction with di...
متن کاملIdentification and quantitative determination of flavonoids in the aerial parts of Teucrium polium by HPLC
Review of literature shows that large varieties of compounds have been found to bear hypoglycemic action. For instance, glycosides afford active principles that lower blood sugar in test animals. Following the I.V. administration of a 4 percent decoction of the dried T. polium herb, a definite reduction of blood sugar level has been exhibited. With reference to PDR for Herbal Medicines for the ...
