    • Hemorrhagic activity was assayed as follows. White mice (4 w, male, ddY strain) were injected subcutaneously in the abdomen with 0.1 mL of test solution, and killed after 24 h. The skin was rapidly removed, and the diameter of each hemorrhagic spot was measured. A test solution was prepared by mixing a solution of snake venom of T. flavoviridis (0.075 mg/mL in saline, 50 μL), and a sample solution (0.50 mg/mL in 20% DMSO-saline, 50 μL) followed by 1 h incubation. In the same way, a solution without sample was injected to the control group. The inhibitory activity was evaluated by the ratio of the diameter of the hemorrhage of the test group and the control group.

    • The weights of the highest-lying conformers used for each isomer were 2-6%. Therefore, contributions to the whole calculated spectra of the energetically higher conformers could be fairly diminutive.
