Abstract

Background: Raphanus sativus is traditionally used as an anti-inflammatory agent.

Objectives: The current study was designed to explore the in vivo anti-inflammatory and antiangiogenic properties of Raphanus sativus seeds oil.

Methods: Cold press method was used for the extraction of oil (RsSO) and was characterised by using GC-MS techniques. Three in vitro antioxidant assays (DPPH, ABTS and FRAP) were performed to explore the antioxidant potential of RsSO. Disc diffusion methods were used to study in vitro antimicrobial properties. In vivo anti-inflammatory properties were studied in both acute and chronic inflammation models. In vivo chicken chorioallantoic membrane assay was performed to study antiangiogenic effects. Molecular mechanisms were identified using TNF-α ELISA kit and docking tools.

Results: GC-MS analysis of RsSO revealed the presence of hexadecanoic and octadecanoic acid. Findings of DPPH, ABTS, and FRAP models indicated relatively moderate radical scavenging properties of RsSO. Oil showed antimicrobial activity against a variety of bacterial and fungal strains tested. Data of inflammation models showed significant (p < 0.05) anti-inflammatory effects of RsSO in both acute and chronic models. 500 mg/kg RsSO halted inflammation development significantly better (p < 0.05) as compared with lower doses. Histopathological evaluations of paws showed minimal infiltration of inflammatory cells in RsSO-treated animals. Findings of TNF-α ELSIA and docking studies showed that RsSO has the potential to down-regulate the expression of TNF-α, iNOS, ROS, and NF-κB respectively. Moreover, RsSO showed in vivo antiangiogenic effects.

Conclusion: Data of the current study highlight that Raphanus sativus seeds oil has anti-inflammatory, and antiangiogenic properties and can be used as an adjunct to standard NSAIDs therapy which may reduce the dose and related side effects.
