摘要:

分别采用水蒸气蒸馏法和同时蒸馏- 萃取法提取白胡椒中的挥发油,得率分别为2.15% 和2.86%;再采用气相色谱- 质谱法从两种方法提取的白胡椒挥发油中共鉴定出32 种化学成分,其中,水蒸气蒸馏法提取的白胡椒挥发油中鉴定出28 种化学成分,从同时蒸馏- 萃取法提取的白胡椒挥发油中鉴定出30 种化学成分。白胡椒挥发油中主要成分有3- 蒈烯、柠檬烯、β- 蒎烯、石竹烯、α- 蒎烯、1- 甲氧基-4-(1- 丙烯基)苯、α- 水芹烯等萜烯类物质。将这两种提取方法相结合,可以更加全面地检测出白胡椒挥发油中的化学成分。

Abstract:

Direct distillation extraction method (DDE) or simultaneous distillation extraction method (SDE) coupled to GSMS was employed to analyze essential oil composition of white pepper. Results demonstrated that DDE and SDE gave essential oil yields of 2.15% and 2.86%, respectively. Added together, 32 chemical components were identified in white pepper essential oils extracted by both methods, of which, 28 were contained in essential oil extracted by DDE and 30 in essential oil extracted by SDE. The major compounds in white pepper essential oil were 3-carene, limonene, β-pinene, caryophyllene, α- pinene, 1-methoxy-4-(1-propenyl)-benzene and α-phellandrene. Besides, all the identified chemical components were quantified. In conclusion, the combination of both extraction methods can help obtain a more comprehensive composition analysis for white pepper essential oil.

Key words: white pepper, volatile oil, direct distillation extraction method, simultaneous distillation on extraction method, GC-MS
