Luteolin content in Thymus vulgaris and its extracts have been compared. Luteolin was separated on a thin- layer of silica gel with three-step gradient elution and determined by HPTLC-photodensitometry. The proposed method is simple and sensitive and can be used for the routine assay of luteolin in phytomedicines containing thyme extracts.
