摘要
采用水蒸气蒸馏法分别提取阔叶箬竹叶和箬竹叶中的挥发油,用乙醚作溶剂进行多次萃取,利用气相色谱-质谱(GC-M S)联用分析二者的化学成分并进行比较。从阔叶箬竹叶提取的挥发油中共鉴定出37种化合物,主要成分为叶醇、1-己醇、苯甲醇、己醛、2-乙基呋喃、β-紫罗兰酮等。从箬竹叶提取的挥发油中共鉴定出49种化合物,主要成分为叶醇、苯甲醇、β-紫罗兰酮、2-己烯醛、苯乙醇、2-甲氧基-4-乙烯基苯酚、2-乙基呋喃等。两种箬叶挥发油中相对含量最高的成分都为叶醇,都含有酮、醛、醇、酚、酯类化合物,且酮、醛、醇的含量明显高于其他成分。
Indocalamus leaves are the generic name of the leaves of Indocalamus （ Graminales） plants. The essential oils in Indocalamus latifolius leaves and Indocalamus tesseUatus leaves were extracted by steam distillation method. Ether was used as the solvent to extract volatile compounds many times. Both the volatile compounds in Indocalamus latifolius leaves and Indocalamus tesseUatus leaves were analyzed by gas chromatography-mass spectrometry （GC-MS）. The results showed that thirty-seven compounds were identified for the essential oils extracted from Indocalamus latifolius leaves, and its main components were found to be 3- hexen-1-ol, （Z） - ; 1-hexanol; benzyl alcohol; hexanal; furan, 2-ethyl- ; 3-buten-2-one, 4- （2,5, 5-trimethyl-1-cyclohexen-1-yl）, （E）-; etc. Forty-nine components were identified for the essential oils extracted from Indocalamus tesseUatus leaves, and its main components were found to be 3-hexen-1-ol, （ Z）-; benzyl alcohol; 3-buten-2-one, 4-（2,5,5-trimethyl-1-cyclohexen-1-yl） -, （E） - ; 2-hexenal; phenylethyl alcohol, 2-methoxy-4-vinylphenol; furan, 2-ethyl-; etc. 3- Hexen-1-ol, （Z）- was the most abundant compound in the essential oils from both Indocalamus leaves. There were ketone, aldehyde, alcohol, phenol and ester in them. The contents of ketones, aldehydes, and alcohols were found higher than those of other compounds in the two essential oils.
