ABSTRACT

BACKGROUND: Rosa rugosa cv. Plena, a cultivar of Rosa rugosa, has a history of more than 1300 years of application in both medicine and food in China. The essential oil of Rosa rugosa cv. Plena (PREO) is one of the most frequently used additives in food, cosmetics and aromatherapy. PREO exhibits some anti-inflammation, antioxidant and nerve alleviating effects. However, the mechanisms behind these effects are still unclear.

METHODS: The composition of PREO was determined by GC‒MS. Network pharmacology was performed to predict the possible compound-target network and analyze the possible targets against inflammation and oxidative stress. An inflammatory immune cell model was constructed by exposing RAW 264.7 cells to LPS. A series of experiments, including biochemical assays, RT‒PCR, and western blotting, were conducted to investigate the anti-inflammatory and antioxidative effects of PREO.

RESULTS: PREO treatment significantly (p < 0.05) alleviated inflammatory and oxidative biomarkers such as NO, ROS, and MDA and preserved SOD and CAT activities. GC‒MS analysis revealed that PREO consists of 57 compounds, mainly monoterpenoids. Network pharmacology revealed that citronellol, farnesol, ethyl octanoate, geranyl acetate, and methyl eugenol were active components interacting with several inflammatory pathway proteins. By measuring the gene and protein expression of possible targets by qRT‒PCR and western blotting, PREO anti-inflammatory responses in LPS-treated RAW 264.7 cells might be associated with the regulation of NF-κB signaling. Molecular docking showed that PREO components can interact with different proteins involved in the NF-κB pathway.

CONCLUSION: The integrated study of molecular analysis and network pharmacology suggested that PREO might be a potential anti-inflammatory agent to treat inflammation and oxidative stress.
