Abstract

The MeOH extract of stems of Actinidia arguta promoted proliferation of cultured bone marrow cells and stimulated formation of myeloid colonies from bone marrow cells. (+)-Catechin (1) and (-)-epicatechin (2) were isolated as active compounds from the MeOH extract. Compounds 1 and 2 stimulated the cell proliferation in a concentration-dependent manner in the range of 1 to 100 mg/mL. Compounds 1 and 2 also stimulated formation of myeloid colonies and enhanced the effect of interleukin-3 (IL-3) to increase the number of colony forming-units in culture (CFU-c). In an ex vivo experiment using a model mouse of decreasing bone marrow functions, orally administrated 1 (100 mg/kg/day) stimulated IL-3-induced CFU-c formation of the bone marrow cells.
