Botanical Adulterants Program Introduces "Lab Guidance Documents" Series to Help Industry Detect Potential Herb AdulterationQuality Consortium's First Lab Guidance Document Reviews 23 Laboratory
Methods for Skullcap
Detailed reports from independent initiative will help quality control personnel identify appropriate analytical methods to authenticate botanical products and detect potential adulteration
(AUSTIN, Texas, Jan. 8, 2015) The
ABC-AHP-NCNPR Botanical Adulterants Program announces the inaugural publication
of its Laboratory
Guidance Document (LGD) series for
botanical ingredients. The LGD
on skullcap (Scutellaria lateriflora) is
the first in the Program’s new series of comprehensive, extensively
peer-reviewed, and up-to-date analytical assessments of methods for
authentication of the identity of ingredients and detection of adulterants. These
free documents – available at no cost thanks to the Program’s underwriters and
supporters – are intended for use by quality control personnel and lab
technicians in the herbal medicine, botanical ingredient, and dietary
supplement sectors to help them choose the most appropriate techniques and
methods for their specific analytical needs.
The American Botanical Council (ABC)-American Herbal Pharmacopoeia
(AHP)-National Center for Natural Products Research (NCNPR) Botanical
Adulterants Program
(BAP) is an international consortium of nonprofit organizations, analytical
laboratories, industry members, professional scientists, and others that
advises industry, researchers, health professionals, and the public about the
various challenges related to adulterated herb and botanical ingredients sold
in commerce. To date, more than 130 American and international parties
financially support or otherwise endorse the Program.
“For the first several years of our Program we published articles alerting
members of the herb industry about adulteration of specific herbs,” said Mark
Blumenthal, founder and executive director of the American Botanical Council
and director of the BAP. “Now, in addition to our continuing series of
publications on adulterated herbs, we are offering technical resources to
assist industry and third-party laboratories to detect adulteration and help
prevent adulterated botanical ingredients and extracts from being processed
into finished consumer products.”
Official compendial methods (e.g., those published in the United
States Pharmacopeia or the European Pharmacopoeia) exist for the
authentication of many botanical materials, but such methods can be outdated
for materials that may be adulterated in ways not conceived at the time of the
development of officially recognized analytical methods, or may not be
applicable to ingredients made using a specific manufacturing process.
Additionally, unscrupulous ingredient suppliers driven by short-term financial
gains have become more creative in finding ways to deceive a potential buyer’s
analysts, making the proper detection of adulterants a potentially daunting,
time-consuming, and increasingly challenging task.
The ABC-AHP-NCNPR Laboratory Guidance Documents are intended to provide
reliable expert guidance on suitable methods to comply with the mandated
requirements of testing for identity, purity, strength, and composition outlined
in the United States Food and Drug Administration’s current
Good Manufacturing Practices (cGMPs) for
dietary supplements. Per the cGMPs, it is the responsibility of the dietary
supplement manufacturers to “conduct at least one appropriate test or
examination to verify the identity of any component that is a dietary
ingredient.”1
The Program’s LGDs provide information about the most suitable analytical
methods for detection of certain adulterants and authentication of specific
botanical materials in the form of whole, cut, or powdered raw materials,
extracts, and essential oils. Recommendations are based on a thorough review of
available analytical methods (e.g., from official and unofficial compendia as
well as the peer-reviewed literature) and input from up to 20 peer reviewers
from academia, government, and industry in multiple countries. The primary
assessment of each method is based on its performance characteristics (i.e.,
suitability in detecting known adulterants); labor and analysis time comprise
the secondary evaluation criteria.
Stefan Gafner, PhD, ABC chief science officer and BAP technical director,
shared his appreciation for everyone who participated in the extensive
peer-review process: “I am grateful for the many analytical experts who spent
the time to peer-review the Skullcap Laboratory Guidance Document. This process
has led to numerous improvements in the paper and has ultimately resulted in a
document that is helpful for those whose job it is to determine the
authenticity of skullcap and the absence of adulterants.”
The BAP’s LGDs begin with a statement of purpose and scope in regard to the
particular species covered, followed by a short overview of the botanical
nomenclature of the species and its known adulterants. Also included are
sections on analytical techniques (generally including macroscopic,
microscopic, chemical, and genetic assays) and a phytochemical composition
overview of the species and known adulterants. The LGDs conclude with a concise
table of strengths and limitations of the various assays. Complete references
are provided with links to original source documents.
The ABC-AHP-NCNPR Botanical Adulterants Program plans to release additional
LGDs in 2015.
For
the skullcap and forthcoming bilberry (Vaccinium myrtillus) extract and black
cohosh (Actaea racemosa) LGDs, 23, 38, and 31 analytical methods
were evaluated, respectively, including the following methods: macroscopic
analysis, botanical microscopy, genetic analysis, HPTLC, HPLC/UHPLC,
flow-injection MS, NMR, and NIR hyperspectral imaging.
“We recently added a skullcap-based product to our line and the conclusions of
the [Skullcap LGD] mirror our own,” commented Katie Huggins, vice president of
Technical Services at Traditional Medicinals, Inc., after reviewing the
skullcap LGD. “I can say from experience that having such a document when evaluating
a new ingredient for inclusion in a product and when writing specifications
would be invaluable.”
To date, the ABC-AHP-NCNPR Botanical Adulterants Program has published five
extensively peer-reviewed and referenced articles on the history of adulteration,
the adulteration of the herbs black cohosh and skullcap, adulteration of
bilberry fruit extract, and so-called “grapefruit seed extract.” These
open-access articles are available on the Program’s webpage here.
The Program also publishes a quarterly e-newsletter, the "Botanical
Adulterants Monitor," that
highlights new scientific publications related to botanical authenticity and
analysis to detect possible adulteration, recent regulatory actions, and
Program news.

About the
ABC-AHP-NCNPR Botanical Adulterants Program
The ABC-AHP-NCNPR
Botanical Adulterants Program is a
consortium of independent nonprofit organizations whose mission relates to
education, scientific research, and quality of botanical dietary ingredients
and related plant-derived materials. The consortium is headed by three
nonprofit groups dealing with education and research on medicinal herbs and
other beneficial plants: the American Botanical Council, the American Herbal
Pharmacopoeia, and the National Center for Natural Products Research at the University
of Mississippi. The program is underwritten or endorsed by more than 130
natural products industry companies, independent analytical laboratories,
contract research organizations, nonprofit and professional organizations,
trade associations, accredited institutions of education in natural medicine,
law firms, and media companies — which are involved in the production, supply,
manufacture, distribution, marketing, analysis, research, and/or education of
herbal dietary ingredients and supplements, in the United States and
internationally. All publications of the Program are available free-access on
its homepage including
the "Botanical
Adulterants Monitor," an
e-newsletter that conveys Program news, regulatory updates, and recent
scientific publications related to adulteration, contamination, identity, and
authenticity of botanical raw materials, extracts, and essential oils.
Companies, organizations, foundations, and/or individuals interested in
supporting this program are invited to contact Ms. Denise Meikel, ABC
Development Director, at (512) 926-4900, ext. 120, or by
