摘要

The leaf latex of Aloe yavellana Reynolds is traditionally used for the treatment of various illnesses of humans and domestic animals in Ethiopia. In the present study, the latex and two major compounds isolated from it, namely, aloin A/B and microdontin A/B were assessed for their larvicidal activity against Amblyomma variegatum tick larvae using a larval packet test (LPT). The LC50 and LC99 of the latex were found to be 35.82 +/- 2.27 and 83.48 +/- 3.95 mg/ml, respectively. Although microdontin A/B showed better larvicidal activity (LC50 = 89.40 +/- 4.45 mg/ml) than aloin A/B (LC50 = 257.69 +/- 6.31 mg/ml), neither of the isolated compounds was as active as the latex suggesting that the compounds acted synergistically or minor compounds with potent larvicidal activity may exist in the latex. The results confirmed that the leaf latex of A. yavellana and its isolated compounds could have the potential to be used as larvicidal against A. variegatum ticks.
