Determination of Characteristic Volatile Component Fingerprint ofPeucedanum PraeruptorumDunn at Different Harvest Periods Based on HS-GC–IMS

We used HS-GC-IMS to determine the characteristic fingerprint of volatile components from PPD across different harvest periods. This approach differs from past studies, which have determined the optimal harvest time of medicinal materials based on only the content of a single active ingredient.
