				 In an attempt to provide further convincing evidence for the variously reported immunomodulatory potentials of mistletoes, bioassay-guided fractionation of the eastern Nigeria mistletoe afforded three compounds: - (-) catechin- 7-O-rhamnoside (1), - (-) catechin-3-O- rhamnoside (2) and a 4?-methoxy-7-O-rhamnoside (3). Their effects on C57BL6 mice splenocytes proliferation and expression of CD69 molecule were determined using flow cytometry techniques and compared to Lipopolysaccharide (LPS; 10 ?g/ml) and Concanavalin A (ConA; 2 ?g/ml) as standards. The antioxidant study was by the DPPH model with ascorbic acid as standard. The compounds (1-3) at 100 ?g/ml showed statistically significant (p.. View More»
