The authors note that Fig. 4 appeared incorrectly. It has come to our attention that the structures of rutin and nicotiflorin have been drawn incorrectly in Fig. 4. The flavanol carbon skeleton of both rutin and nicotiflorin have been incorrectly drawn as 2-phenylnaphthalene-1,4-dione, when they should be 2-phenyl-4H-chromen-4-one. The corrected figure and its legend appear below. The online version has been corrected. (Figure Presented).
