Abstract
Antitermitic activity of Taiwania (Taiwania cryptomerioides Hayata) against Coptotermes formosanus Shiraki was demonstrated in laboratory tests. Block s of sapwood and heartwood from T. cryptomerioides exhibited antitermitic a ctivity. Bioassays revealed that heartwood essential oil exhibited the high est antitermitic activity, followed by sapwood essential oil and then the n -C6H14 soluble fraction when tested at 10 mg/g. The order of termite mortal ity of three compounds purified from n-C6H14 soluble extracts of heartwood was cedrol > alpha -cadinol > ferruginol. The termite resistance of T. cryp tomerioides wood can be attributed to the termiticidal activity of cedrol a nd alpha -cadinol.
