| stationaryphase=Stationary phase, i.e. Silica gel 60, F254
| mobilephase=Toluene, ethyl acetate 95:5 (v/v)
| prep=Sample:Mix 500 mg of powdered sample with 5 mL of toluene and sonicate for 10 minutes, 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 5 µL of linalool in 1 mL of toluene; Dissolve 5 µL of linalyl acetate in 1mL of toluene; Optional: Dissolve 10 µL of cineole in 1 mL of toluene.

# 4 µL Lavender flower 1
# 6 µL Lavender flower 1

System suitability test: Linalyl acetate: violet zone at Rf ~ 0.57; Linalool: violet zone at Rf ~ 0.27.

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. The chromatogram of the test solution shows a violet zone at Rf ~ 0.27 corresponding to reference linalool (blue arrow) and a brownish zone due to cineole (green arrow). Above this zone there is a pink zone at Rf ~ 0.42 (red arrow). A faint violet zone at Rf ~ 0.57 corresponding to linalyl acetate may be present.

Test for other species: The chromatograms of Lavender oil and Lavanin show an intense violet zone at the position of linalyl acetate (black arrow). Lavender flower shows no yellow zone below the linalool reference (violet arrow).
