AI Article Synopsis
- The study aimed to measure the amount of imperatorin in tetraploidy radix angelicae dahuricae and compare it with the original diplontic varieties.
- A chromatographic method was employed using a specific column and solutions at set conditions for precise measurement.
- Results showed that tetraploid radix had 0.460% imperatorin, while diplontic species had only 0.225%, indicating that the tetraploid variety contains double the active component.
Article Abstract
Objective: To determine the content of imperatorin in the tetraploidy radix angelicae dahuricae, and compare it with the original diplontic varites.
Method: The chromatographic method was carried out on Nova-pak (4.6 mm x 200 mm, 5 microns) column with acetonitrile-water solution as a mobile phase. The flow rate was 1 ml.min-1. the detection wavelength was at 248 nm, and the column temperature was 25 degrees C.
Result: The eontent of was imperatorin in the tetraploidy radix 0.460% and 0.225% imperatorin in the diplontic species.
Conclusion: The content of the mainly active constituent in the tetraploid is double to what it is in the original diplontic species.
