| Popis: |
An investigation of plants in tropical Africa was conducted to search for new naturally bioactive substances. A total of 62 plant species were obtained from Cameroon, Zaire, and Tanzania. The extracts were tested for insecticidal, herbicidal, and fungicidal activities. Insecticidal activity was found in 23 extracts. Of the 51 extracts from Cameroon and Tanzania, herbicidal activity was detected in seven, and fungicidal activity in seven. Polyascias fulva, Crassocephalum manii, Vernonia amygdalina, Vernonia vogetti, Poga oleosa, Gnidia glauca, Trema guinensis and Combretum bracteatum were evaluated to be highly promising candidates for further investigation of their active constituents on the basis of their potency and/or broad spectrum of biological activities. |
