This study was performed to investigate improving immune activities of natural water-soluble sulforaphane extracted from Brassica oleracea var. italica by nano encapsulation process. The nanoparticles of the sulforaphane extracted with ultrasonification process at 60℃ promoted human B and T cell growth, about 7~35% compared to the control. The secretion of IL-6 and TNF-α from T cells were also enhanced as 2.6×10-4pg/cell and 2.1×10-4 pg/cell, respectively, by the adding nano samples. NK cell activation was improved about 8%, compare to the control in adding cultured medium of T cell added nano samples. It was also found that sulforaphane extracted from B. oleracea var. italica had highly inhibitory activity on hyaluronidase as IC50 about 200 μg/ml. It can be concluded that natural water-soluble sulforaphane samples by nano-encapsulation, each size is 200 nm, extracted from B. oleracea var. italica has high immune activities through higher efficiency of bio-activation than conventional extracts.
