Isolation and identification of toxin with insecticidal activity from fungus Lecanicillium muscarium

The chemical structure of a new insecticidal toxin isolated from the mycelium of micromycete Lecanicillium muscarium was defined. IR-, UV-, mass-spectrometry methods as well as a set of NMR-experiments were used in the work. The isolated toxin is referred to terpenoids and is an interesting for practical use.
