Abstract:
Twelve types of gingko flavonoids were separated with SDS/n -C4 HgOH/n- C7 Hls/H2O microernlusion as developer on polyamide film. The polarity of the microemulsion was regulated through adding or reducing water. Compared with general mobile phase, the sensitivity of detection was improved markedly and the test results were satisfied. By means of HPTLC, fingerprint was argued on gingko flavonoids. It can meet the needs of simple and convenient, reasonable standard quality control methods.
