Abstract:
OBJECTIVE:To establish a method for the contents determination of 5 coumarins in sulphur-fumigated and no sul-phur-fumigated Glehnia littoralis,and investigate the effect of sulphur fumigation on the coumarins in G. littoralis. METHODS:HPLC was performed on the column of Hypersil ODS C18 with mobile phase of acetonitrile-0.1% phosphoric acid (gradient elu-tion)at a flow rate of 1.0 ml/min,detection wavelength was 295 nm,column temperature was 30 ℃,and the volume was 20 μl. RESULTS:The linear range was 0.121 5-12.15 μg/L for psoralen,0.389-38.9 μg/L for xanthotoxin,0.055-5.5 μg/L for bergapten, 0.070 5-7.05 μg/L for imperatorin and 0.092 5-9.25 μg/L for isoimperatorin(r≥0.999 7);RSD of precision test was lower than 1.0,RSDs of reproducibility and stability tests were lower than 3.0;recovery was 98.01%-101.97%(RSD<3.0%,n=6). CON-CLUSIONS:The content of coumarins in G. littoralis was obviously decreased after sulphur fumigation. the method is simple and accurate,and canbe used for the quality control of sulphur-fumigated and no sulphur-fumigated G. littoralis.
