用水蒸气蒸馏法提取挥发油，以气相色谱一质谱(GC-MS)联用方法对湖南红足蒿嫩叶的化学成分进行分 析，以比色法测定其鲜嫩叶的多糖含量，并用高效液相色谱(HPLC)方法分析乙醇提取物的指纹谱。结果表明，(1) GC-MS分析鉴定出湖南产红足蒿嫩叶挥发油中的17个化合物，占挥发油总量的87．76％，主要有樟脑(26．94％)、 桉树脑(15．59％)、石竹烯(13．29％)、大牻牛儿烯D(5．45％)；(2)比色法测定出湖南红足蒿鲜嫩叶的多糖含量达 1．55％；(3)湖南红足蒿鲜嫩叶乙醇提取物的HPLC指纹图谱重现性好，成分保留时间在100 min之内，在280 nm 下5～100 min内有25个面积较大的色谱峰，说明湖南红足蒿嫩叶化学...

The chemical constituents of Artemisia rubripes Nakai leaves were investigated in this paper.The volatile oil was extracted from leaves of A.rubripes by steam distillation and the components of the volatile oil were separated and identified by GC-MS;Polysaccharose was determined by colorimetric analysis and the HPLC-finger print was established.As a result,17 compounds had been identified,accounting 87.76% of total volatile oil.The main components of volatile oil were camphor（26.94%）,eucalyptol（15.59%）,caryophyllene（13.29%）,germacrene D（...
