Quality Control and Standardization of A
Manufactured Herbal Product
-
In general, quality control is based on three
important pharmacopoeial definitions:
1. Identity : is the herb the one it should be?
2. Purity : are there contaminants, e.g., in the form of
other herbs which should not be there?
3. Content or assay: is the content of active constituents
within the defined limits?
-
4. Plant materials are chemically and naturally variable.
5. The source and quality of the raw material are variable.
6. The methods of harvesting, drying, storage, transportation,
and processing (for example, mode of extraction and polarity
of the extracting solvent, instability of constituents, etc.)
have an effect.
Several problems not applicable to synthetic drugs
influence the quality of herbal medicine:
1. Herbal medicines are usually mixtures of many
constituents.
2. The active principle(s) is (are), in most cases unknown.
3. Selective analytical methods or reference compounds may
not be available commercially.

1. Macroscopic examination
Organoleptic evaluation of refers to the evaluation of a herbal by colour, odour, size, shape, taste and special features
including touch, texture etc.
-
Pieces: Mild, crumbly, brownish orange
yellow color; almost circular shape to
elliptical, sometimes branched; width of
0.5 cm to 3 cm long, 2 cm to 6 cm,
thickness 1mm to 5mm; generally curved
irregular, sometimes there is a base (upih
leaves and roots). Limit cortex and central
cylinder is sometimes unclear.
File fault: rather flat, dusty, yellow orange
to reddish-brown

-
2. Microscopic examination
Today microscopic evaluation is indispensable in the initial
identification of herbs, as well as in identifying small fragments
of crude or powdered herbs, and detection of foreign matter
and adulterants.
At other times, microscopic analysis is needed to determine
the correct species and/or that the correct part of the species
is present.
-
The epidermis: a single layer of cells, flat polygonal shape,
cell wall into the cork. Hair coverings: conical, straight
or slightly curved; length of 250 m to 890 m, thick
walls.
Hypodermis: consists of several layers of cells stretched
tangentially, menggabus cell wall.
Periderm: consists of 6 layers up to 9 layers of cell shaped
rectangular, cell wall into the cork.
Cortex and central silibder: parenchimatic, composed of large
cells, filled with starch.
Starch grains: single, oval or ovoid shape with one end having a
round bulge or until almost triangle with one side rounded;
lamella is less clear; less clear hilum contained in the bulge
at the end point; length of 10 m and 60 m, generally 20
m to 40 m, 10 m wide and 28 m, generally 14 m to
20 m. Cell secretion: ................ ect.

Herbal medicine should be made from the stated part of the plant and be devoid of other parts of the same plant or other plants.
They should be entirely free from harmful foreign matters such as fungus, insects, sand, stones, poisonus, chemical residues, microbial contaminants, ect.
3. Determination of Foreign Matter
For chemical residues: TLC, HPTLC, HPLC is often used to
detect the contaminants.
-
To determine ash content the plant material is burnt and the
residual ash is measured as total and acid-insoluble ash.
Total ash is the measure of the total amount of material left
after burning and includes ash derived from the part of the
plant itself and acid-insoluble ash.
4. Determination of Ash
-
Contamination by heavy metals such as mercury, lead, copper, cadmium, and arsenic in herbal drugs can be
attributed to environmental pollution, and clinically relevant
dangers for the health and should therefore be limited.
5. Determination of Heavy Metals
The main methods commonly used are atomic absorption spectrophotometry (AAS), inductively coupled plasma (ICP)
and neutron activation analysis (NAA).
-
6. Determination of microbial contaminants &
aflatoxins
Medicinal plants may be associated with a broad variety of microbial contaminants, represented by bacteria, fungi, and
viruses.
Herbal medicine normally carry a number of bacteria and
molds, often originating in the soil. Poor methods of
harvesting, cleaning, drying, handling, and storage may also
cause additional contamination.
While a large range of bacteria and fungi are from naturally
occurring microflora, aerobic spore-forming bacteria
frequently predominate.
-
The European Pharmacopoeia also specifies that E. coli and Salmonella spp. should be absent from herbal
preparations.
However it is not always these two pathogenic bacteria that cause clinical problems. For example, a fatal case of
listeriosis was caused by contamination of alfalfa tablets
with the Gram positive bacillus Listeria monocytogenes.
Aflatoxin-producing fungi sometimes build up during storage. Procedures for the determination of aflatoxin
contamination in herbal drugs are published by the WHO.
After a thorough clean-up procedure, TLC is used for
confirmation.
-
7. Determination of pesticide residues
Many pesticides contain chlorine in the molecule, which, for example, can be measured by analysis of total organic
chlorine. In an analogous way, insecticides containing
phosphate can be detected by measuring total organic
phosphorus.
Herbal medicine are liable to contain pesticide residues, which accumulate from agricultural practices, such as
spraying, treatment of soils during cultivation, and
administering of fumigants during storage.
.
-
8. Determination of radioactive contaminations
There are many sources of ionization radiation, including radionuclides, occurring in the environment. Hence a certain
degree of exposure is inevitable. Dangerous contamination,
however, may be the consequence of a nuclear accident.
The WHO, in close cooperation with several other international organizations, has developed guidelines in the
event of a widespread contamination by radionuclides
resulting from major nuclear accidents.
-
9. Analytical methods
The quantitative determination of constituents has been made easy by recent developments in analytical instrumentation. Recent advances in the isolation, purification, and structure elucidation of naturally occurring metabolites have made it possible to establish appropriate strategies for the determination and analysis of quality and the process of standardization of herbal preparations.
Classification of plants and organisms by their chemical constituents is referred to as chemotaxonomy.
-
TLC, HPLC, GC, quantitative TLC (QTLC), and high-performance TLC (HPTLC) can determine the
homogeneity of a plant extract. Over-pressured layer
chromatography (OPLC), infrared and UV-VIS spectrometry,
MS, GC, liquid chromatography (LC) used alone, or in
combinations such as GC/MS, LC/MS, and MS/MS, and
nuclear magnetic resonance (NMR), are powerful tools,
often used for standardization and to control the quality of
both the raw material and the finished product.

2. Parameter Spesifik
-
New standardization of herbal medicine
True standardization, a definite phytochemical or group of constituents
is known to have activity.
Ginkgo with its 26% ginkgo flavones and 6% terpenes is a classic
example. These products are highly concentrated and no longer
represent the whole herb, and are now considered as
phytopharmaceuticals. In many cases they are vastly more effective
than the whole herb.
Not true standardization is based on manufacturers guaranteeing the
presence of a certain percentage of marker compounds; these are not
indicators of therapeutic activity or quality of the herb.
