Abstract
Effects of various fractions of methanol extracts from fruiting bodies of Cordyceps sinensis on the Iymphoproliferative response, natural killer (NK) cell activity, and phytohemagglutinin (PHA) stimulated interleukin-2 (IL-2) and tumor necrosis factor-α (TNF-α) production on human mono-nuclear cells (HMNC) were studied. Two of the 15 column fractions (CS-36-39 and CS-48-51) significantly inhibited the blastogenesis response (IC50 =; 71.0 ± 3.0 and 21.7 ± 2.0 μg/ml, respectively), NK cell activity (IC50 =; 25.0 ± 2.5 and 12.9 ± 5.8 μg/ml, respectively) and IL-2 production of HMNC stimulated by PHA (IC50 =; 9.6 ± 2.3 and 5.5 ± 1.6 μg/ml, respectively). TNF-α production in HMNC cultures was also blocked by CS-36-39 and CS-48-51 (IC50 =; 2.7 ± 1.0 and 12.5 ± 3.8 μg/ml, respectively). These results indicated that neither CS-36-39 nor CS-48-51 was cytotoxic on HMNC, and that immunosuppressive ingredients are contained in Cordyceps sinensis.Keywords
