| prep=Sample: Mix 500 mg of powdered sample with 5 mL of methanol and sonicate for 10 minutes, then centrifuge or filter the solutions and use the supernatants / filtrates as test solutions.

Derivatization reagent: Anisaldehyde reagent, Preparation: 170 mL of ice-cooled methanol are mixed with 20 mL of acetic acid, 10 mL of sulfuric acid and 1 mL of anisaldehyde, Use: Dip (time 0, speed 5), heat at 100°C for 5 min.
| detection=Saturated chamber; developing distance 70 mm from lower edge; relative humidity 33%
| referencesamples=Reference: Dissolve 1 mg of rutin in 5 mL of methanol. Dissolve 1 mg of arbutin in 5 mL of methanol.

System suitability test: Rutin: light yellow zone at Rf ~ 0.34 (white RT); Arbutin: light brown zone at Rf ~ 0.46 (white RT).

Identification: Compare result with reference images. The fingerprint of the test solution is similar to that of the corresponding botanical reference sample. Additional weak zones may be present. Under UV 254 nm the chromatogram of the test solution shows one quenching zone at Rf ~ 0.53. Under white RT there is a brownish grey zone at Rf ~ 0.53 above the position of reference arbutin (blue arrow). A greyish violet double zone is seen around Rf ~ 0.30 just below reference rutin.

Test for adulteration: No zone is seen at Rf ~ 0.40 (red arrow, European vervain herb).
