this investigation determined that vitamin c intake of c.w. was higher than o.p. , s. c. and c. statistically, there was a significant difference between c.w. and c. blood ascorbic acid levels of o.p. and s.c. were lower than c.w. and c. , a significant difference was observed. urinary vitamin c in all groups was lower than controls and this indicates that even though vitamin c intake was high,...

Ascorbate Determination, 2,4-Dinitrophenylhydrazine Microamounts of vitamin C could be readily determined in 20 ul-samples using the 2,4-dinitrophenylhydrazine method together with separation by thin layer chromato­ graphy. The condensation reaction was carried out for 5 min at 100 °C on a glass fibre disc. Purification of vitamin C hydrazones was accomplished by repeated separation on TLC plat...
