Why Herbal Medicine Analysis?
Modernizing the old art of herbal medicine practice requires addressing the three
interrelated issues of ‘quality’, ‘safety’, and ‘efficacy’. The 'pharmaceutical
quality' of plant medicines is critically important as it does also affect the
efficacy and safety of the drugs. Among many other factors, the quality of a
given plant medicine could be variable due to:
-
wrong species/variety of
plant selected
-
wrong/different plant
parts selected
-
potential degradation of
active compounds during harvest, transport and storage
-
inadequate/wrong
extraction procedure
-
wrong/different
time/season of collection resulting in a qualitative and quantitative
differences of active compounds
-
qualitative and
quantitative differences in active constituents based on environmental
differences
-
contamination of plant
medicines with microbes, microbial toxins, environmental pollutants, or heavy
metals
have been the major subjects of concern
in the herbal medicine industry.
Various
preparations of plant medicines including decoctions, infusions, powders, juices
are used in traditional medicine by means of one or multiple routes of
administration. Such crude plant medicine preparations are complex mixture of
different compounds, which may act in an agonistic, antagonistic, synergistic,
complementary or toxic manner. In the first instant, the therapeutic
potential of such medicines need to be VALIDATED through PHARMACOLOGICAL ASSAYS.
Establishing the scientific basis of plant medicines would promote the evidence
based approach in these practices and also gives
confidence among reluctant users of the green medicine.
If the
chemical constituents responsible for the therapeutic activity of
plant medicines are known, STANDARDIZATION OF THE
DRUGS IS POSSIBLE. Alternatively, the active constituents
may be isolated and used by their own. Hence, PHYTOCHEMICAL ANALYSIS of plants is an essential
component of the ‘quality, safety and efficacy’ issues of plant medicines.

our exemplary HPLC-based assay site.
