After extracting saponin from bast of Iju which grows on Okinawa,We measured its poisonous effect on fish and its hemolysis effect.The results are as follows.1) The dry bast contains 0.03 per-cent of pure Iju saponin,and ultimate analysis reveals that it contains 3.12 per-cent of ashes.2) No hemolysis effect is observed in the extracted solution,but the purer the saponin becomes the stronger is the hemolysis effect of the solution.3)As the poisonous effect on fish,the extracted solution is strong.The solution diluted to one thousandth bring the fish to death in 60minutes,and the effect decreases as the solution is purified.These results show that the pure-Iju-saponin has strong hemolysis effect,and it may be used as an effective Sputum remedy(expectorant).
