Table 1 Toxicity of fractions from HPLC purification of peak of CM-IV against blowfly, tobacco budworm larvae and mice.

All other fractions were found to have no toxicity in the above insect bioassays. The toxicity against mice was not determined for other HPLC fractions. At least 6 animals of each species were assayed with each fraction. + indicates 100% mortality. - indicates zero mortality a. 1 μg/100 mg larvae was injected b. 3 μg/g body weight was injected.
