- Abstract
[Objectives] To explore the influence of different times of steaming and exposing to the sun on the fingerprint of Polygonati Rhizoma by studying the HPLC fingerprint of Polygonati Rhizoma processed products with different times of steaming and exposing to the sun, and to provide a basis for the determination of the best processing technology of Polygonati Rhizoma. [Methods] SETSAIL II AQ-C18 (5 µm x 250 mm x 4.6 mm) was used as the column, the column temperature was 30 °C, pure water (A) and acetonitrile (B) were eluted gradually, 0-10 min, B (5% -10%), 10-30 min, B (10% -35%), 30-40 min, B (35%-60%), 40-45 min, B (60%-100%), flow rate 1 mL/min, absorption wavelength 200 nm. [Results] The relative retained peak area RSDs of the common peaks in the precision, reproduc-ibility and stability tests were all less than 5%. There were 17 common peaks in the fingerprint of nine batches of samples, and the retention time of Peak 2 was basically the same as that of the reference peak of 5-HMF. Peak 4 mainly existed in the chromatogram of Sample 3 to Sample 5, peaks 5 and 11 mainly existed after Sample 3, peaks 9, 14 and 16 mainly existed after Sample 6, and peaks 12 and 17 mainly existed after Sample 4. [Conclusions] A total of 17 common peaks were obtained, and the Peak 2 was the designated peak, and the chemical components of each processed product were different.
