High Performance Thin Layer Chromatographic Identification
Ribwort plantain (leaf) (Plantago lanceolata) Lane Assignments Lanes, from left to right (Track, Volume, Sample):
Reference Sample(s) Reference: Dissolve 1 mg of aucubin in 10 mL of methanol. Dissolve 1 mg of acteoside (verbascoside) in 10 mL of methanol Stationary Phase Stationary phase, i.e. Silica gel 60, F254 Mobile Phase Ethyl acetate, methanol, water 81:11:8 (v/v/v) Sample Preparation Method 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: Chloramine - trichloroacetic acid reagent; Preparation: Solution A: Dissolve 300 mg of sodium-N-chloro-(4-methylbenzene) sulfonamide in 10 mL of water. Solution B: Dissolve 10 g of trichloroacetic acid in ethanol and fill up to a volume of 40 mL. Mix solution A and B and shake. Use: Dip (time 0, speed 5), heat at 100°C for 8 min. Detection Method Saturated chamber; developing distance 70 mm from lower edge; relative humidity 33% Other Notes Images presented in this entry are examples and are not intended to be used as basis for setting specifications for quality control purposes. System suitability test: Aucubin: black zone at Rf ~ 0.10 (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 white RT the chromatogram of the test solution shows a black zone at Rf ~ 0.10 corresponding to aucubin; under UV 366 nm this zone appears brown (red arrows). Under UV 366 nm there is a blue zone at Rf ~ 0.35 and a red zone due to chlorophylls right below the solvent front. Test for adulteration: Under UV 366 nm no brown zone is seen at Rf ~ 0.10; under white RT no black zone is seen at Rf ~ 0.10 (Grecian foxglove leaf, Greater plantain leaf).
