Larvicidal activities against Aedes aegypti have been determined in the ethanolic extracts obtained from 51 Brazilian medicinal plants. Eleven of the 84 extracts studied showed significant (LC50 < 100 microg mL(-1)) activities against larvae, with extracts from Annona crassiflora (root bark, LC50 = 0.71 microg mL(-1); root wood, LC50 = 8.94 microg mL(-1)) and Annona glabra (seed, LC50 = 0.06 microg mL(-1)) showing the highest activities. The results obtained should be of value in the search for new natural larvicidal compounds.
已对从51种巴西药用植物中提取的乙醇提取物进行了针对埃及伊蚊的杀幼虫活性测定。在所研究的84种提取物中，有11种对幼虫表现出显著（LC50 < 100微克/毫升）活性，其中番荔枝（根皮，LC50 = 0.71微克/毫升；根木，LC50 = 8.94微克/毫升）和光叶番荔枝（种子，LC50 = 0.06微克/毫升）的提取物活性最高。所获得的结果对于寻找新的天然杀幼虫化合物应具有价值。
