Discussion About Application of Thin Layer Chromatography in Current Quality Standard Control
The application of thin layer chromatography(TLC) in
Chinese Pharmacopoeia
experienced from scratch to less to more
but the proportion of thin layer chromatographic scanning used in recent editions of
Chinese Pharmacopoeia
has decreased.With the further improvement of the quality standard system of traditional Chinese medicine(TCM)
the shortcomings of TLC identification methods have been gradually revealed
such as the low penetration rate of instrument
poor repeatability and stability of the results
lower identification speed than high performance liquid chromatography(HPLC) and so on.Thus it gradually became untimely.In the process of formulating quality standard control of TCM
researchers should not be conformist
and TLC identification should not be a necessary choice for the qualitative identification.And HPLC has the possibility to completely replace TLC
but TLC can be used as a supplement to HPLC.In order to fully lower testing cost
shorten testing cycle
improve the efficiency of identification
we suggested quality standard system of TCM should be sharply reduced TLC identification method and increased identification of HPLC characteristic spectrum; and try to do "one condition
one map" . Unless absolutely necessary
national quality standards(such as
Chinese Pharmacopoeia
) should use TLC identification as a recommended method rather than a mandatory standard.
