Reversed phase HPLC profile of extract of the green yarn in specimen 10141 monitored at 350 nm (profile A) and at 600 nm (profile B); the y-axis units are mAU, the x-axis, minutes. Alizarin (which is red) is not seen in these profiles, but it does appear when the elution is monitored at 450 nm (cf. as in Figure 2). The large peak at about 34 min in profile A is a non-flavonoid artifact.
