Abstract:
Objective To study the FT-IR fingerprint characteristics of Hedysari Radix from 8 producing counties in Gansu Province; To provide references for identification and application of Hedysari Radix in different producing counties. Methods FT-IR fingerprints of 110 batches of Hedysari Radix from 8 producing counties in Gansu Province were collected in the wave number range of 4000–400 cm-1. The common pattern of the fingerprints were analyzed, and the similarity analysis were used to analyze the FT-IR fingerprints of Hedysari Radix from 8 producing counties. The FT-IR fingerprint characteristics of Hedysari Radix from 8 producing counties in Gansu Province were compared. Results The rank of average similarity of FT-IR fingerprints of Hedysari Radix from 8 producing counties was Tanchang County > Li County > Xihe County > Wudu District > Zhang County > Min County > Longxi County >Weiyuan County, and Hedysari Radix from Longxi County and Weiyuan County were very different from other producing counties. The FT-IR fingerprints of Hedysari Radix from Longnan City (Tanchang County, Li County, Xihe County and Wudu District) were similar, and the average similarity was relatively high; while that from Dingxi City (Zhang County, Min County, Longxi County and Weiyuan County) were similar, and the average similarity was relatively low. Hedysari Radix from every producing county had a significant and unique FT-IR fingerprint characteristic. Conclusion The identification and application of Hedysari Radix from 8 producing counties in Gansu Province can be realized according to FT-IR fingerprint characteristics.
