Title: Extraction and Determination of Antisepsis and Germicidal Components in Fennel Seed
Abstract: Selecting the ethanol and water as the solvent extraction of fennel aldehyde,the influence of various external factors on the extraction efficiency. The experimental results showed that the reaction medium was 6 mol / L HCl, chromogenic agent dosage was 2 mL,and response time was 20 min. When the reaction temperature was room temperature,the determination of anisaldehyde was the best. At room temperature,best for anhydrous ethanol solvent extraction of anisaldehyde; extraction temperature was 32 ℃ and extraction time was 30 days,fennel aldehyde extraction efficiency can reach the highest value of 2. 45%,while water extract fennel aldehyde content was lower. The extraction temperature of 55 ℃,the extraction efficiency of anisaldehyde was only 0. 27%. Results showed that the ethanol extraction efficiency was higher than the extraction efficiency of distilled water,both differ as much as 20 times or so.
