Bioaktivitas Biji Kolowe (Chydenanthus excelsus) terhadap Larva Nyamuk Aedes aegypty
Keywords:
Kolowe Seed (Chydenanthus excelsus), Aedes aegypti mosquito larvaeAbstract
Kolowe seed (Chydenanthus excelsus) bioactivity against Aedes aegypti masquito larvae was investegated. Assay of Kolowe seed preparation used fresh seed powder, dry powder, rough extract (methanol extract), n- butanol extract fraction, and aethyl acetate extract fraction. Plant material taken from Kamaru, Buton, Indonesia on March 2007. Fresh powder bioactivity (LC50 = 230.60 ppm); dry powder (LC50 = 225.55 ppm); rough extract/ methanol (LC50 = 245.70 ppm); n- butanol extract fraction (LC50 = 235.75 ppm); aethyl acetate extract fraction (LC50 = 250.55 ppm). The research results illustrated that the bioactivity seed from kolowe strong enough against mosquito larvae A. aegypti and dry powder has a stronger bioactivity than the other.
