System suitability test (under white RT): CAMAG test dye mixture III: A blue zone: at Rf ~ 0.28 and an orange red double zone at Rf ~ 0.48.

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 366 nm the chromatogram of the test solution shows a blue zone right above the application position, a diffuse red zone at Rf ~ 0.35, above it another blue, a red and a purple zone and a characteristic blue zone at Rf ~ 0.71. Under white RT there is an intense and diffuse purple zone at Rf ~ 0.35. Above it there is a purple zone at Rf ~ 0.50 and at Rf ~ 0.60. A blue zone is visible at Rf ~ 0.67.

Test for adulteration: Under white RT no zones are seen at Rf ~ 0.60 (black arrow) and Rf ~ 0.67 (red arrow) (Yunnan onosma root, Tibetan onosma root, or low quality/old Arnebia root).
