BIOAKTIVITAS ZAT EKSTRAKTIF KULIT Acacia auriculiformis A. Cunn. ex Benth. TERHADAP RAYAP TANAH (Coptotermes curvignathus Holmgren)
Abstract: This research was
undertaken mainly to isolate and identify antitermitic substances that may be
prospective as wood natural preservative from the bark of Acacia auriculiformis
A. Cunn. ex Benth. The woodmeal of the samples were extracted with acetone. The
acetone extract was then fractionated into n-hexane soluble fraction, ethyl
ether soluble fraction, ethyl acetate soluble fraction, and insoluble fraction.The
antifeedant bioassay test was carried out by treating paper discs with extracts
at six level of concentration i.e. 0%, 2%, 4%, 6%, 8%, and 10% (w/w). The
bioassay test revealed that ethyl ether soluble fraction exhibited high
toxicity to subterranean termite Coptotermes curvignathus Holmgren
(concentration of 4% has been indicated very strong activity).
