Abstract:
Two triterpenes, beta-amyrin and 12-oleanene 3beta, 21beta-diol, were isolated as a mixture from the chloroform soluble fraction of an ethanol extract of Duranta repens Linn (Verbenaceae) stem. The structures of the two compounds were confirmed by analysis of their IR, (1)H-NMR, (13)C-NMR and LC-MS spectral data. The mixture of beta-amyrin and 12-oleanene 3beta, 21beta-diol (compound 1) was highly effective against the larvae of the mosquito, Culex quinquefasciatus Say (Diptera: Culicidae), as a mosquitocide.
