Anti-melanoma cancer activity and chemical profile of the essential oil of Seseli yunnanense Franch

Abstract

Seseli yunnanense appertains to the Apiaceae family. S. yunnanense is known as an herbal remedy to treat several illnesses in Chinese traditional medicine. In this research, the essential oil (EO) of the aerial part of S. yunnanense (SYEO) was isolated by hydro-distillation apparatus. The chemical composition of the volatile oil was recognized using Gas chromatography (GC)/flame ionization detector and GC-Mass spectrometry methods. 1,1-Diphenyl-2-picrylhydrazyl and MTT assays were carried out to investigate the antioxidant and anti-melanoma cancer activity of the oil. The chromatography results showed SYEO was dominated by sesquiterpenes of α-bisabolol 40.19%, β-eudesmol 13.12%, and the phenolic compound eugenol 12.06%. SYEO scavenged the free radical of DPPH by IC50 of 454.66 ± 7.25 μg/mL. In the MTT assay, SYEO showed a dose depending on the viability of the melanoma cell lines of HMV-II, SK-ML-2, G-361, and HT144. The highest activity was obtained against the HMV-II cell line with IC50 of 116.82 ± 2.34 μg/mL. The cytotoxicity of SYEO was examined against HUVEC cell lines. The results exhibited the safety of EO for the human normal cells. The results showed the EO of S. yunnanense is a potent agent for treating melanoma cancer.
