INHIBITION OF RAT LENS ALDOSE REDUCTASE BY QUERCETAGETIN AND PATULETIN

摘要

In this paper the results of inhibition of the Aldose reductase(AR) activity on Wistar rat lens by Quercetagetin extracted from Tagetes erects Linn and by Patuletin extracted from Tagetes patula Linn are reported.Quercetagetin inhibited AR of the rat lens by 93.9% at 10^(-4)M, 76.0% at 10^(-5)M and 13.3% at 10^(-6)M. Patuletin inhibited AR of the rat lens by 100% at 10^(-1)M, 80% at 10^(-5)M and 22.7% at 10^(-6)M respectively. The results show that these two flavones are lens AR Inhibitors, but further ...
