PREPARATION AND CHARACTERIZATION OF QUERCETIN DERIVATIVES QUERCETIN THIOSEMICARBAZONES HAVING HIGH SUNSCREEN PROTECTION AND ANTICANCER ACTIVITY

摘要

The present invention relates to a process for the preparation and characterization of new Quercetin derivatives Quercetinthiosem carbazones based sunscreen cream having high sunscreen protection and anticancer activity. Following invention is described in detail with the help of Figure 1 of sheet 1 shows the diagram for a Thin Layer Chromatography results where the mobile phase used are Toluene: Ethyl acetate: Formic Acid 6:2:0.8 (v/v/v), Figure 2 of sheet 1 shows the diagram for FTIR graph for the Quercetin, Figure 3 of sheet 2 shows the diagram for FTIR graph for the Quercetin and Figure 4 of the sheet 2 shows the diagram for FTIR graph for the Quercetin Thiosemicarbazone derivative.
