Gas chromatography coupled to mass spectrometry characterization, anti-inflammatory effect, wound-healing potential, and hair growth-promoting activity of Algerian Carthamus caeruleus L ( Asteraceae ).

OBJECTIVES: The roots of Carthamus caeruleus have been used by the population of Northern Algeria to treat several pathological conditions, including wound healing and hair growth. The present study was conducted to evaluate the anti-inflammatory activity, wound-healing potential, and hair growth-promoting activity attributed to C. caeruleus root.

MATERIALS AND METHODS: In this study, we have investigated the anti-inflammatory effect using carrageenan-induced paw edema test, evaluated the wound-healing potential by linear incision wound model, and evaluated hair growth activity using in vivo hair growth-promoting test attributed to C. caeruleus root. Preliminary phytochemical screening and gas chromatography coupled to mass spectrometry (GC/MS) characterization were also performed.

RESULTS: It was found that the methanolic extract of C. caeruleus was characterized by the presence of tannins, flavonoids, anthocyanins, leucoanthocyanins, sennosides, free quinones, saponins, glycosides, mucilage, and coumarins. The GC/MS analysis could identify 22 compounds and showed that the major chemical constituents were palmitic acid (12.88%), mono(2-ethylhexyl) phthalate (12.75%), and 5-(hydroxymethyl)-2-furancarboxaldehyde, (9.19%). The phytoextract strongly inhibited ( P < 0.001) paw edema formation in mice. The roots of C. caeruleus also showed a significant ( P < 0.05) wound-healing and hair growth-promoting effects.

CONCLUSION: The results indicate the richness of the roots of the Algerian C. caeruleus in biomolecules. These molecules exhibit an excellent reducing inflammation activity, a wound-healing property, and an interesting hair-promoting growth activity. All in all, the findings promote the usage of the Algerian C. caeruleus as an effective and a safe potential skincare alternative remedy.
