【摘要】 目的:提取毛老虎叶子挥发油并分析研究其化学成分。方法:采用水蒸气蒸馏法提取,馏出液先用;醚萃取得到挥发油(Ⅰ),再用乙酸乙酯进一步提取得挥发油(Ⅱ),并通过GC/MS技术对其进行分析。结果:共分离鉴定出化学成分78个,其中挥发油(Ⅰ)鉴定出68种化合物,挥发油(Ⅱ)鉴定出25种化合物。结论:挥发油的主要成分为1.8-桉树脑、石竹烯、2,6,6-三甲基二环[3.1.1]庚-2,3-二醇等化合物。更多还原

【Abstract】 AIM: The essential oil was extracted from Hyptis suaveolents(L.) Piot leaves and the chemical components were analyzed. METHODS: The essential oil was extracted by steam distillation.Then the distillate was treated with ether and essential oil was obtained(Ⅰ).Then surplus oil distillate was extracted with ethyl acetate and essential oil was got(Ⅱ).Essential oil was analyzed by GC/MS. RESULTS: 78 compounds were identified in total.68 compounds were identified from essential oil(Ⅰ).25 compounds were detected from essential oil(Ⅱ). CONCLUSION: The principle constituents of the essential oil are 1.8-Cineole、 Caryophyllene、 Bicyclo(3.1.1) heptane-2,3-diol,2,6,6-trimethyl-etc.更多还原
