    Abstract:
    Carthami Flos(flowers of Carthamus tinctorius) with the effects of activating blood, dredging meridians, dissipating stasis, and relieving pain is one of the commonly used traditional Chinese medicines for promoting blood circulation and resolving stasis in clinical practice. So far, more than 210 compounds in Carthami Flos have been isolated and reported, including quinochalcones(safflower yellow pigments and red pigments), flavonoids, spermidines, alkaloids, polyacetylenes, and organic acids. Safflower yellow pigments, as the main water-soluble active components of Carthami Flos, is commonly obtained by the water extraction method, while red pigments are commonly obtained by the alkali extraction and acid precipitation method. In recent years, natural deep eutectic solvents as green solvents have demonstrated promising application prospects in the extraction and separation of pigments from Carthami Flos. This review systematically summarizes the chemical constituents of Carthami Flos and analyzes the extraction process of pigment components from Carthami Flos, aiming to provide a reference for further utilization of Carthami Flos resources.
