摘要

水蜈蚣（kyllinga brevifolia）為莎草科（Cyperaceae）植物。將新採集的水蜈蚣葉與根莖，經清洗、風乾與攪碎等步驟後，以水蒸氣蒸餾帶出揮發性精油成分，經溶劑萃取、鹼處理後得一黃褐色之中性精油。
　　將精油先以管柱色層分析粗分成碳氫化合物與含氧化合物兩大部份，分別以氣相色層分析儀及氣相色層質譜儀進行光譜鑑定，初步瞭解精油大致的成分；另再以管柱色層分析進行單離與純化，然後測其IR和NMR光譜進行結構分析，或與已知標準物之Gc-Rt值及文獻光譜核對，以確認其所含精油成分。
　　在碳氫化合物部分共確認了十個成分，分別為α-Pinene, β-Pinene, α-Cubebene, Copaene, γ-Cadinene, α-Humulene, 4,10-Dimethy1-7-isopropy1 bicyclo[4.4.0]-1,4-Decadiene,γ-Muurolene, α-Elemene, Cyperene在含氧化合物部分共確認了五個成分，分別為Terpinene-4-ol, Myrtenol, Geraniol, δ-Cadinol, Phytol。以上十五個成分均是在水蜈蚣植物中首次發現的成分。

The essential oil were obtained from the leaves and rhizomes of kyllinga brevifolia by steam distillation and solvent extraction. It was treated with base to remove the acidic compounds. The neutral essential oil was separated and purified by column chromatography.
Fifteen compounds which were identified by comparison of GC retention times, IR, GC／MS and NMR spectra wereα-Pinene, β-Pinene, α-Cubebene, Copaene, γ-Cadinene, α-Humulene, γ-Muurolene, α-Elemene, Terpinene-4-ol, Myrtenol, Geraniol, 4,10-Dimethy1-7-isopropy1-bicyclo[4.4.0]-1,4-Decadiene, δ-Cadinol, Cyperene and Phytol.
