摘要
Curculigo orchioides Gaerten belongs to the family Amaryllidaceae. The rhizomes of the plants are used for the treatment of decline in strength, jaundice and asthma. Its methanolic extract has been shown to enhance phagocytic activity of macrophages. Present studies have led to the isolation of two phenolic glycosides and a purified glycoside fraction. These were studied for their effect on macrophage migration index (MMI), haemagglutination (HA) titre, plaque forming cell (PFC), PHA-induced blast transformation of lymphocytes (BTL) and delayed type hypersensitivity (DTH). Significant immunostimulant activity was found in purified glycoside-rich fraction isolated from the ethyl acetate extract. The exact structure of the active glycoside is yet to be determined. The enhancement of HA titre and PFC count on one hand and that of DTH response on the other indicates that glycoside fraction stimulates both Immoral and Cell-mediated immune responses. Glycoside fraction stimulates immune response by acting both on macrophages and the lymphocytes. (C) 2003 Elsevier Ireland Ltd. All rights reserved.
