Anthocyanins are another type of plant pigment that are purple or red. Say you run a chromatography experiment using the same setup as you did in this lab, and you find that anthocyanins do not move from the line of origin. Assuming the solvent traveled the same distance as in your experiment (D in Table 1 above), what is the Rf value of anthocyanin?

  1. Anthocyanins are another type of plant pigment that are purple or red. Say you run a chromatography experiment using the same setup as you did in this lab, and you find that anthocyanins do not move from the line of origin. Assuming the solvent traveled the same distance as in your experiment (D in Table 1 above), what is the Rf value of anthocyanin?
