[Study on the Fingerprint of Kingkong Zedoary Turmeric Oil]
Objective:
To study the fingerprint of Zedoary Turmeric Oil (ZTO) as the bulk drug of Kingkong Elemene for making it safe, effective, stable, and controllable.
Methods:
Fingerprints were detected by gas chromatography. β-elemene peak was regarded as reference peak (S). The relative peak area of each common peak and the relative retention time were calculated. With a total of modes for reference, the fingerprints of 10 batches of Kingkong ZTO were detected, and their similarity was calculated by traditional Chinese medicine (TCM) fingerprint similarity calculation software.
Results:
The determination method was stable and reliable. Totally 19 common characteristic peaks of Kingkong ZTO was found. The fingerprint similarity of these batches of Kingkong ZTO were not lower than 0.96.
Conclusions:
Gas chromatography for detecting the fingerprint of Kingkong ZTO was reliable and repeatable. The established fingerprint of Kingkong ZTO could guarantee the quality stability and safety of different product batches.
