Hereinafter, the present invention will be described more specifically with reference to Examples.
The scope of the present invention is not limited to these examples. (Example 1) (1) Preparation of quercetin-3,4'-diglucoside Onion was homogenized together with the skin in an equal volume of 80% methanol, and then suction-filtered with a filter paper. The extract obtained by concentrating the filtrate under reduced pressure was dissolved in deionized water, and passed through a reverse-phase Amberlite XAD-2 column equilibrated with deionized water. The column was washed with the same amount of deionized water as the sample solution, and then eluted with methanol. The fraction eluted with methanol was concentrated to dryness under reduced pressure. This fraction is dissolved in a small amount of 50% methanol,
Gel filtration was performed with Toyopearl HW-40 equilibrated with% methanol. Quercetin-3,4'-diglucoside was obtained in one fraction at a purity of almost 100%. Quercetin-3,4'-diglucoside thus obtained was consistent with known ones in the change in absorption spectrum and mass fragment analysis accompanying the addition of aluminum chloride and sodium acetate. (2) Assay for UV protection effect Next, quercetin-3,4'-diglucoside was added to the culture at various concentrations, and human histiocytic lymphoma cells, U
The UV protection effect was examined in an assay system using -937. The protective effect increased with the concentration, and almost 100% of the effect was obtained at about 400 micromol / liter. On the other hand, no lethal effect was observed even at a concentration of 800 micromol / liter (FIG. 1).
