A description of the experience
Trop Biomed. 2004 Dec;21(2):61-7. Adulticidal activity of some Malaysian plant extracts against Aedes aegypti Linnaeus. Hidayatulfathi O1, Sallehuddin S, Ibrahim J. 1Faculty of Allied Health Sciences, Universiti Kebangsaan Malaysia, Jalan Raja Muda A. Aziz, 50300 Kuala Lumpur, Malaysia.
The adulticidal activity of methanol extracts from three Malaysian plants namely
- Acorus calamus Linn.,
- Litsea elliptica Blume and
- Piper aduncum Linn.
against adult of Aedes aegypti (L.) were studied. Standard WHO bioassay tests were used to evaluate the effectiveness of these plant extracts.
The hexane fraction from methanol extract of Acorus calamus rhizome was the most effective, exhibiting LC50 and LC90 values of 0.04 mgcm(-2) and 0.09 mgcm(-2) respectively. For L. elliptica, the methanol fraction also displayed good adulticidal property with the LC50 and LC90 values of 0.11 mgcm(-2) and 6.08 mgcm(-2) respectively. It is found that hexane fraction of the P. aduncum crude extract was the least effective among the three plants showing LC50 and LC90 values of 0.20 mgcm(-2) and 5.32 mgcm(-2), respectively.
However, although A. calamus showed lowest LC values, the LT50 results indicated that the methanol fraction of L. elliptica was most potent extract among the extracts tested.
