本土樹種食茱萸之抽出物應用於台灣家白蟻防治
Evaluation of Anti-Formosa termite by Extracts of Alianthus Prickly Ash
摘要
本研究探討台灣產芸香科植物－食茱萸（Zanthoxylum ailanthoides, Alianthus Prickly Ash）對台灣家白蟻（Coptotermes formosamus, Formosa termite）之抑制活性，以食茱萸葉部及材部進行萃取，將萃取之抽出物浸漬濾紙及注入木塊進行餵食試驗，逐步篩選出最有效的活性部位。由試驗結果知，經過溶劑萃取後食茱萸葉部及材部之甲醇抽出物對白蟻皆具有致死活性及忌避性，在濾紙及木塊試驗中皆以葉部甲醇抽出物之效果最佳，於濃度10mg/mL之濾紙試驗在第6日時造成試驗白蟻全數死亡；經葉部甲醇抽出物注入之木塊白蟻致死率為51.6％，而葉部乙酸乙酯可溶部注入之木塊白蟻致死率為56.3％。濾紙及木塊之重量損失率隨抽出物濃度呈現反比關係，注入濃度增加則重量損失率降低。本研究結果將有助於天然抗白蟻治劑研發之參考。

The aim of this study is to figure out the plant of Rutaceae produced in Taiwan with inhibitory activity for the formosa termite (Coptotermes formosanus). At first, the experiment select for anti-termite activity with Alianthus Prickly Ash (Zanthoxylum ailanthoide). As the results shown, Zanthoxylum ailanthoides leaves had a better inhibitory effect for Coptotermes formosamus. Both of methanol extraction of leaves and wood from Zanthoxylum ailanthoides had mortality and repellent activities for termites. The extraction of Zanthoxylum ailanthoides leaves had a good inhibitory effect on both of filter paper and wood block tests. The mortality rate was 100% at 10mg/mL of the filter paper test for 6 days The mortality rate of leaves methanol extraction and ethyl acetate soluble fraction was 51.6, 56.3% at soaked blocks test The relationship between that sample soaked concentration and weight loss of filter paper are inversed. The results can provide for anti-termite agents development.
