Abstract

Schinus molle: a new source of natural fungitoxicant.

Abstract

The oil of S. molle exhibited max. fungitoxic activity during the screening of some essential oils against some common storage (Alternaria alternata, Aspergillus flavus, Penicillium italicum) and animal pathogenic (Microsporum gypseum, Trichophyton mentagrophytes, T. rubrum) fungi. It showed absolute toxicity against animal pathogens and mild activity against storage fungi. The effective concn of the oil varied from 200 to 900 p.p.m. The toxicity of the oil persisted up to 80°C and 90 days of storage but declined when autoclaved. It withstood heavy inoculum density. The oil exhibited a narrow range of activity and was found to be more effective than Multifungin. The oil was characterized by its various physicochemical properties. It was found to comprise 50 constituents. It appeared that some changes in the oil constituents during storage affected its fungitoxic potency.
