Journal Title: UNKNOWN - Year 2018, Vol 7, Issue 4
Abstract
Malaria, a hazardous infirmity caused by a parasitic malady of the red blood cells, is without question harming to the wellbeing. In the present investigation, the chemosuppresive and haematopoietic activities of 200 mg/kg and 400 mg/kg body weight of unrefined ethanolic concentrates of three Chinese green teas (BIA 849, TD 570 and GB/T19598) were assessed using the 4-day suppressive anti-plasmodial assay in mice Plasmodium berghei (NK65 strain) pre-infected mice. The effect of the extracts on weight of the animals was evaluated. It was observed that 200 mg/kg bw (body weight) of BIA 849 and GB/T19598 were as potent as 5 mg/kg bw of chloroquine, with percentage suppressions of 58.97 ± 5.04, 57.63 ± 5.62 and 57.50 ± 4.5, respectively. TD570 at 200 mg/kg bw was more effective in suppressing plasmodium. 400 mg/kg body weight of TD570 and GB/T19598 extracts were more potent than 5 mg/kg bw of chloroquine having 100 % chemosuppression. The chemosuppression of BIA 849 did not change altogether at 400 mg/kg bw. The haematological parameters, WBC, RBC and MCV did not significantly change in the groups treated with the tea extracts utilizing suppressive model of malaria treatment contrasted with the uninfected group and were comparable to those treated with chloroquine. Haemoglobin concentration nonetheless, varied significantly with respect to the uninfected group. Weight changes were most significant with 200 mg/kg bw of TD 570 treated group (32 % increase) on suppression. All in all, the green teas displayed high chemosuppressive and haematopoietic possibilities and are thusly prescribed as contender for additionally screening as elective antimalarial drugs.
