To identify anti-allergic actions of LSS, the degranulation was evaluated in IgE andDNP-BSA stimulated RBL-2H3 cells. At the concentration of 100 μg/ml of methanol (MeOH) extract and Methylene chloride(MC) and Ethyl acetate (EtOAc) fractions, the degranulation was significantly inhibited 16.7%, 16.7% and 27.9% respectively. And then, to assess anti-inflammatory effects of LSS, IL-4 and IL-13 mRNA level were detected in PMA/ionomycin(PI)-induced RBL-2H3 cells and cell proliferation and IL-4 mRNA level in isolated splenocytes from Balb/c mice. LSSMeOH extract and MC and EtOAc fractions significantly decreased the level of IL-4 and IL-13 mRNA in PI-induced RBL-2H3 cells and showed inhibitory effects on cell proliferation and expression of IL-4 mRNA level in mouse splenocytes. Taken together, these results suggest that LSS has potential anti-allergic and anti-inflammatory effects and EtOAc fractionis the most effective in regulating immune responses.
