The invention discloses a method for preparing senkyunolide I from extract of Chinese angelica, which comprises the following steps: (1) purifying by using macroporous resin; (2) purifying by extraction; and (3) purifying by chromatography. In the invention, the preparation process of the senkyunolide I is simplified, and the yield is increased to a great extent. In addition, the method prepares the senkyunolide I by using the extract of Chinese angelica which is a traditional Chinese medicine instead of Szechuan lovage rhizome which is an original source plant. Therefore, the method can be used in the industrial preparation of senkyunolide I. |
