A. Temizer et al., DIFFERENTIAL-PULSE POLAROGRAPHIC-DETERMINATION OF FLAVONOIDS .2. TOTAL FLAVONOIDS IN CRUCIATA TAURICA (PALLAS EX WILLD) EHREND-SL, Journal of the Chemical Society of Pakistan, 17(3), 1995, pp. 180-182
A differential pulse polarographic method was described for the determ
ination of rutin that is obtained from Cruciata taurica (Pallas ex wil
ld.) Ehrend s.I. Differential pulse polarograms of rutin show a distin
ct peak at -1.83 V (vs Ag, AgCl) at pH 6.00 Sorensen buffer. The total
amount of flavonoids in Cruciata taurica (Pallas ex Wild) Ehrend.s.I.
has been found to be 0.45% by using rutin as a standard.
