Abstract

The genus Moricandia (Brassicaceae) comprises about eight species that were used in traditional medicine. Moricandia sinaica is used to alleviate certain disorders such as syphilis and exhibits analgesic, anti-inflammatory, antipyretic, antioxidant, and antigenotoxic properties. Throughout this study, we aimed to figure out the chemical composition of lipophilic extract and essential oil obtained from M. sinaica aerial parts using GC/MS analysis, as well as their cytotoxic and antioxidant activities correlated with the major detected compounds' molecular docking. The results revealed that both the lipophilic extract and the oil were found to be rich in aliphatic hydrocarbons, accounting for 72.00% and 79.85%, respectively. Furthermore, the lipophilic extract's major constituents are octacosanol, γ-sitosterol, α-amyrin, β-amyrin acetate, and α-tocopherol. Contrarily, monoterpenes and sesquiterpenes accounted for the majority of the essential oil. The essential oil and the lipophilic extract of M. sinaica showed cytotoxic properties towards human liver cancer cells (HepG2) with IC50 values of 126.65 and 220.21 µg/mL, respectively. The lipophilic extract revealed antioxidant activity in the DPPH assay with an IC50 value of 2679 ± 128.13 µg/mL and in the FRAP assay, moderate antioxidant potential was expressed as 44.30 ± 3.73 µM Trolox equivalent/mg sample. The molecular docking studies revealed that ꞵ-amyrin acetate, α -tocopherol, γ-sitosterol, and n-pentacosaneachieved the best docking scores for NADPH oxidase, phosphoinositide-3 kinase, and protein kinase B. Consequently, M. sinaica essential oil and lipophilic extract can be employed as a viable management strategy for oxidative stress conditions and the formulation of improved cytotoxic treatment regimens.
