366 nm – two distinct bands at Rf 0.32 (bright blue) and at Rf 0.1 (yellow).
White light derivatised – two characteristic bands at Rf 0.4 (red) and Rf 0.23 (dark brown) with a minor orange band underneath
366 nm after derivatisation – four distinct bands at Rf 0.3 (blue-green), Rf 0.35 (beige); Rf 0.38 (light brown), Rf 0.45 (light blue)
