| 中文摘要 | 本試驗採取新店華林場及陽明山鄒梅農場之土肉桂造林木葉試材,抽 取其揮發性油,計算鮮重試材中之收率,並以毛細管氣相層析加質譜分析鑑定其 主成分。由結果得知,精收率最高達2.1%(華林之H7號樣品),最低為0.43%(鄒 梅之T2樣品);平均收率則華林為1.1%,鄒梅為0.77%。成分分析方,中部種源 樣品之桂皮醛多高於50%,南部種源僅在面15%∼25%左右,與母樹之含量變異 相符。然而,香豆素含量普遍偏低,此與中部種源性質符合,但與南部者有所出 入。採自中部蓮華池及南部扇平之天然生土肉桂,其葉部、幹皮及根皮之精油收 率和主成分也分別測定和鑑定。結果顯示,各部位之收率順序為根皮> 葉>幹皮, 最高者為扇平之根皮2.4%。成分,方面,葉部主要為伽羅木醇 (蓮華池54%, 扇平24%),而桂皮醛為蓮華池19%,扇平13%,香豆素則蓮華池7.2%,扇平 21%,幹皮所含桂皮醛較葉部為高,分別為蓮華池51%,扇平 31%。香豆素在 扇平幹皮中達35%,而蓮華池者僅5.8%。至於根皮中,桂皮醛含量更高,蓮華 池者平均82%,扇平者平均38%,香豆素在扇平根皮中有 20%,蓮華池1.6%。 |
| 英文摘要 | The leaf samples of planting Cinnamomum osmophloeum Kaneh. from Farm Hwa-Lin at Hsin-tien and Farm Tsou-mei at Yamg-ming San were collected and extracted to get the volatile oils. The yields of oil from each fresh sample was calculated, and the main components were analyzed and identified with CGC/ MS. It was shown that the highest oil-yield was 2.1% from sample H7 of Hwa-Lin, while the lowest was 0.43% from T2 of Tsou-mei. The average yields from samples of Hwa-Lin and Tsou-mei were 1.1% and 0.77% respectively. From the composition analyses of essential oils, it was found that the samples of Central Taiwan's Provenances contained high concentration of Cinnamic aldehyde (>50%) and low amount of Coumarin, consistent with their mother trees' properties. But, the contents of southern Taiwan's provenances were mot consistent with the characters of their mother trees, especially the unexpected low concentration of Coumarin. The samples of leaf, stem bark, and root bark of natural standing C. Osmophloeum were collected from Lien-Hwa-Che (denoted as L) and Shan-pin (denoted as S), sited at Nan-Tou and Kao-Hsiung respectively. The yields of essential oils were determined to be in the sequency of root bark>leaf>stem bark, with the highest of 2.4% from Shan-pin's root bark. The compositions of individual parts may be shown as the following: Leaf-Linalool(L. 54%, S. 24%) Coumarin (L. 7.2%, S. 21%) Cinnamic aldehyde (L. 19%, S. 13%) Stem bark-Cinnamic aldehyde (L. 51%, S. 31%); Coumarin (L. 6%, S. 35%) Root bark-Cinnamic aldehyde (L. 82%, S. 38%) Coumarin (L. 1.6% S. 20%) |
