Reference Sample(s) Reference: Dissolve 2.6 mg of patent blue V in 10 mL of ethanol. Dissolve 2.8 mg of quinaldine red in 10 mL of ethanol. Stationary Phase Stationary phase, i.e. Silica gel 60, F254 Mobile Phase 1-Butanol, formic acid, water 40:10:12: (v/v/v) Sample Preparation Method Sample: Mix 1 g of powdered sample with 10 mL of methanol and sonicate for 10 minutes, then centrifuge or filter the solutions and use the supernatants /filtrates as test solutions. 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: Patent blue V: blue zone at Rf ~ 0.36; Quinaldine red: orange zone at Rf ~ 0.63. 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 test solution shows two violet-blue zones at Rf ~ 0.33 and Rf ~ 0.40.
