Mobile In the present study, anticoagulation activity of mucus extracted from sea anemones Heteractis magnifica and Stichodactlyla haddoni at three different concentrations was tested in blood plasma, using two assay system and the results are presented in Table 1. In APTT assay the activity was a maximum in Stichodactyla haddoni this species prolonged clotting time of maximum 700 seconds about 8.7 fold higher than that of control (80 seconds) of all the concentration tested and the clotting time is higher in the Stichodactyla haddoni then Heteractis magnifica. Thus, the sea anemone mucus extracts time clotting was noted in the ratio 8.7 is the high folds in the species of Stichodactyla haddoni in APTT assay. In PT assay a few extract showed higher concentration in the species Stichodactyla haddoni 3.5, 2.5 and 2.5 folds higher respectively in 100, 500 and 1000µgmL-1 than the control. All other extract shows lower anti coagulant activity in PT assay.
