Abstract:
Background: Quercetin is a kind of flavonoid with important bioactivities, such as
hypoglycemic, antioxidant, anti-inflammatory, and anti-allergic properties. Although it is
unstable, it is worth exploring how to better exert its anti-allergic effect.
Objective: The current study aimed to elucidate the anti-allergic effect of quercetin liposomes on
RBL-2H3 cells in vitro.
Methods: Quercetin liposomes were prepared to improve the anti-allergic activity of quercetin
through a green thin-film dispersion method. We compared the anti-allergic effects of quercetin
and quercetin liposomes in RBL-2H3 cells. The anti-allergic activity of the quercetin liposomes
was evaluated by the level of β-hexosaminidase, histamine, Ca2+, IL-4, IL-8, and MCP-1.
Results: The results showed that quercetin liposomes could significantly restrain the release of
β-hexosaminidase and histamine, calcium influx, and the expression of inflammatory factors,
whose effect is stronger than quercetin.
Conclusion: Collectively, our research suggests that the quercetin liposome can be used as a
potential allergy antagonist.
