摘要:
采用GCMS技术,对台琼海桐蒴果皮的水蒸气蒸馏油样,以及蒴果籽的索氏提取油样的甲酯化样品进行分析。样品中各化学成分的相对含量用面积归一化法确定。在实验条件下,果皮油样共分离出24个峰,鉴定了17个,占总峰面积的94.70%。其主要成分为柠檬烯(24.27%)、γ榄香烯(8.30%)、β榄香烯(1713%)、α榄香烯(16.02%)、长叶龙脑(15.52%)和α松油醇(2.17%),α石竹烯(1.88%)。果籽油的甲酯化样品共分离出16个峰,鉴定了12个,占总峰面积的96.69%,其主要成分为棕榈油酸(3483%)、反油酸(26.63%)、14甲基十五烷酸(17.08%),十八烷酸(1.88%),十四烷酸(1.61%)。分析结果说明台琼海桐蒴果皮富含挥发性芳香油,而蒴果籽油含有多种脂肪酸。
Abstract:
The oil of capsule peel was obtained by steam distillation,and oil of capsule seeds by Soxhlet extraction from Pittosporum pentandrum var.formosanum. At first,the main chemical compositions and their relative contents were identified and determined in peel oil and methylesterificated seed oil sample by using GCMS and area normalization technology. 24 isolate peaks appeared in GCMS spectrogram of the capsule peel oil sample. 17 peaks,9470% in total peak area,had been identified. There were limonene(24.27%);γelemene(8.30%);βelemene(1713%);αelemene(16.02%);Longiborneol(15.52%);αterpinol(2.17%)and αcaryophyllene(1.88%)mainly. 16 isolate peaks appeared in GCMS spectrogram of the methylesterificated seed oil sample. 12 peaks,96.69% in total peak area,had been identified. There were palmitoleic acid(34.83%);elaidic acid(26.63%);14methylpentadecanoic acid(17.08%);octadeca alkyl acid(1.88%)and tetradecanoic acid(1.61%) mainly. These results showed that capsule peels contained largely volatile essential oil and capsule seeds oil contained various fattyacid.
