目的:研究丹参不同部位挥发油化学成分并进行比较。方法:采用水蒸气蒸馏法提取丹参根、茎、叶及花挥发油,运用气相色谱-质谱联用(GC-MS)方法对各部位提取挥发油进行分析,用面积归一法分别计算各成分的相对含量。结果:从丹参根、茎、叶及花挥发油中共鉴定45种成分。结论:丹参根与茎、叶及花挥发油中主要化学成分差别很大,而茎、叶、花中主要化学成分大致相同。
Objective: To study the chemical constituents of volatile oil in different parts of Radix Salviae Miltiorrhizae and compare them. Methods: The essential oil of Radix Salviae Miltiorrhizae, stem, leaf and flower was extracted by steam distillation. The volatile oil was extracted from each part by gas chromatography-mass spectrometry (GC-MS) method. The area normalization method was used to calculate the relative content of each component content. Results: 45 components were identified from the essential oil of Radix Salviae Miltiorrhizae, stem, leaf and flower. Conclusion: The main chemical constituents in roots, stems, leaves and flowers of Salvia miltiorrhiza are very different, while the main chemical components in stem, leaves and flowers are almost the same.
