| Abstract:
Aromatic plant volatile oils have been known since antiquity to possess biological activities, notably antibacterial, antifungal and antioxidant properties [Deans & Svoboda, 1990a]. In more recent years, attempts have been made to isolate and identify the compound[s] responsible for such activity. However, in many cases these compounds of interest have yet to be fully characterised. The use of powerful analytical techniques such as GLC, GC-MS and FT-NMR is essential. This study examined a number of volatile oils from both temperate and tropical plants being a joint investigation into plants from Zimbabwe that are used in ethnopharmacy. These plants showed marked biological activity when tested against bacteria and filamentous fungi. The identity of the compounds exhibiting such activity is being undertaken using GLC, GC-MS and NMR. Their biological activity will be studied singly and in combination since synergistic effects may exist. | |
