采用同时蒸馏萃取法(SDE)分别提取6月份采摘的黄兰叶、花和果实的挥发油,运用毛细管气相色谱-质谱联用法结合计算机检索对其挥发油进行了化学成分分析。分别从黄兰叶、花和果实的挥发油中鉴定出了17、35和38种化合物。用面积归一化法测定了3种挥发油中各种成分的相对质量分数,各占总峰面积的92.18%、99.23%和99.24%。3种挥发油化学组成各有异同,主要成分有β-芳樟醇、大牻牛儿烯B、石竹烯、桉叶醇、β-榄香烯等。黄兰挥发油中富含大量在香料和医药行业有重要用途的高生物活性化合物。
The volatile oil of the leaves, flowers and fruits harvested from June was extracted by simultaneous distillation extraction (SDE). The chemical constituents of the volatile oil were analyzed by capillary gas chromatography-mass spectrometry and computer search. A total of 17,35 and 38 compounds were identified from the volatile oils of the leaves, flowers and fruits, respectively. The relative mass fractions of various components in the three volatile oils were determined by area normalization, accounting for 92.18%, 99.23% and 99.24% of the total peak area respectively. The chemical constituents of the three kinds of volatile oil are similar and different. The main components are β-linalool, Daphniletium B, Caryophyllene, Eucalyptol and β-Elemene. Huanglan volatile oil is rich in a large number of spices and the pharmaceutical industry has important uses of high bio-active compounds.
