Analysis & Evaluation of Medicinal Herbs
A Challenging Task For Analytical Chemists
Herbs are a complicated HPLC
system of mixtures.
Chromatography is the GC
method of choice for
identification of such 30
complicated mixtures.
Chromatographic techniques
are intended to obtain a
characteristic fingerprint of a
herbal drug.
Fingerprint: It relates a particular quality with definite
chemical constituents. This will help to provide batch-
to-batch reproducibility.
