Application of Supercritical Fluid Extraction in the Bioactive Principles of Chinese Herbs- The Fruits of Cnidium monnieri
碩士 === 中原大學 === 化學系 === 88 === A supercritical fluid extraction (SFE) method was used for the extraction of coumarins (osthole, imperatorin, xanthotoxin, and isopimpinelline) in the fruits of Cnidium monnieri (L.) Cusson . In this study, the extraction conditions used were 40 and 50℃, at 3000, 4000...

Cusson . In this study, the extraction conditions used were 40 and 50℃, at 3000, 4000, and 5000 psi, respectively. Meantime, entrainers such as n-hexane, acetone, and ethanol were also added in the extraction. All residues and extracts were assayed with HPLC. The results showed that the four coumarins had the highest yield at 40℃, 5000psi, the extraction yield for osthole, imperatorin, xanthotoxin, and isopimpinelline were 52%, 49%, 35%, and 29%, respectively. When the entrainer was n-hexane, we got the highest extraction yield for osthole, imperatorin, xanthotoxin, the extraction yield were 75%, 76%, 61%, and 62%. 謝博進 2000 學位論文 ; thesis 0 zh-TW |
