Objectives: This study was conducted with objectives of comparatively investigating effects of original Kyungokgo and Iksuyongjingo plus Sparassis crispa which is gamibang of Kyungokgo on antioxidant improvement, immunity improvement, and sensory evaluation.
Methods : Total phenol and DPPH scavenging activity were measured to determine antioxidant improvement of original Kyungokgo and Iksuyongjingo plus Sparassis crispa . While, blood and serum study were conducted and effect on the cytokines were observed from the immunosuppressed rat induced by methotrexate (MTX). Control group was administered with a drinking water, Kyungokgo group was administered with a original Kyungokgo 200 mg/kg, and Iksuyongjingo plus Sparassis crispa group was administered with a Iksuyongjingo plus Sparassis crispa 200 mg/kg for 20 days. Further, intensity and preference evaluation were performed as sensory evaluation.
Results : It was observed that Iksuyongjingo plus Sparassis crispa significantly increased total phenol and DPPH scavenging activity, proving that these can improve antioxidant activities. In the immunosuppressed rat, Iksuyongjingo plus Sparassis crispa significantly decreased IL-2 level, significantly increased Il-10 level, and significantly increased neutrophils, RBC, HGB, and HCT levels, indicating that it is effective in increasing immunity. Further, Iksuyongjingo plus Sparassis crispa significantly improved intensity and preference in the sensory evaluation.
Conclusions : From the above results, it is concluded that Iksuyongjingo plus Sparassis crispa which is gamibang of Kyungokgo can act effectively on improving antioxidant activity and immunity, and can attribute convenient intake by improving diet preference.
