Clematis, Pointed At Both Ends, And Medicinal Herbs Such As Volatile Oils

This thesis studied the research into the efficacy of the volatile ingredients of Clematis chinensis Osbeck and Anemone raddeana Reg. et al carried out by the writer. In the experiments the writer used the hydrodistillation apparatus to extract the volatile oils from these medicines and, at the same time, the GC-MS method to make a qualitative and quantitative analysis of the volatile oils. Through research of the volatile ingredients of Clematis chinensis Osbeck from different growing areas, the writer finds that their volatile ingredients consist of similar components, namely, organic acid, organic acid ester, terpenoid, phenol, et al. They all contain 4-Cyclopentene-l,3-dione, alpha-Terpineol, Ethanone, l-(2-hydroxy-4-methoxyphe nyl)- et al, but there are some difference in their relative content. The major components of the volatile oil of Anemone raddeana Reg. were Hexadecanoic acid, Ethanone, l-(2-hydroxy-5-methylphenyl)- et al. 2-Furancarboxaldehyde, Ethanone, l-(2-hydroxy-5-methylphenyl)- et al were identified from the volatile oil. Hexadecanoic acid, 9,12-octadecadienoic acid, Isoborneol et al were the major components of the volatile oil from Pulsatilla chinensis Bge. In the meanwhile, the writer also analyses the volatile ingredients of Pogostemon cablin (Blanco) Benth of different origins and finds they possesses similar components, that is, terpenoid, alcohol et al. They all contain Patchouli alcohol, 2H-Pyran-2-one, 3-acetyl-4-hydroxy-6-methyl-3-(4-methyl-l-oxo-pentyl)-, Azulene,l,2,3,5,6,7,8,8A-octahydro -l,4-dimethyl-7-(l-methylethenyl)- et al, but there are some difference in their relative content.In the experiments, the writer made use of the technique of the highly efficient capillary gas chromatographic spectrum to research the gas chromatographic fingerprint spectrum of the volatile oil of Clematis chinensis Osbeck The technique is able to authenticate traditional Chinese medical materials quickly and help control thequality of traditional Chinese medicine. In the meanwhile it also develops new uses for the gas chromatographic spectrum to make a sample analysis of complex components.
