台琼海桐蒴果皮油及籽油的主要挥发性化学成分
Main chemical compositions with volatility in peel essential oil and seed oil of Pittosporum pentandrum var.f ormosanum capsule
摘要
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 normali-zation technology. 24 isolate peaks appeared in GCMS spectrogram of the capsule peel oil sample. 17 peaks,94. 70% in total peak areathad been identified. There were limonene(24. 27%) 5y-elemene(8, 30%) ; β-elemene(17.13%) ;α elemene(16.02%)(Longibomeol(15. 52%); crterpinol ( 2. 17%)and crcaryophyllene(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%) joctadeca alkyl acid(l. 88%)and tetradecanoic acid(l. 61%) mainly. These results showed that capsule peels contained largely volatile essential oil and capsule seeds oil contained various fatty-acid.关键词
