Glossary of Botanical Microscopy Terminology References and Bibliography Index Reviews "This volume identifies plants by the classical method of light microscopy. Most earlier texts only listed plants used as drugs and never as extensively as the economically valuable plants covered in this book. With a forward by our past DEB Norman Farnsworth, this text does an excellent job of offering adequate background on plant anatomy, diagnostic techniques, and tools of the trade. The drawings and images are very good and it is now no longer necessary to use analytical tools if one has good references such as this to identify plant powders and parts when manufacturing herbal products. This microscopy text is invaluable to the natural products industry as it raises the scientific standards.
For example, a type of tea adulterant containing Adenostyles alliariae caused serious liver disease after long-term use 11 , Adulterant tea mixed with Illicium anisatum which contains neurotoxic substances 13 and cases of toxicity caused by Aconitum 14 and Datura metel 15 have also been reported.
All of these life- threatening poisoning cases threaten the safe use of TCM. As a result, the detection of adulterant drugs is becoming a growing challenge 8. Traditional identification methods recognize materials by their morphological characteristics, and these methods primarily depend on human expertise. However, in some cases, it is extremely difficult for taxonomists to definitively identify plant genera, such as Crataegus and Salix.
Chemical analyses, such as high-performance liquid chromatographic- mass spectrometric HPLC—MS 21 , near-infrared spectroscopy NIRS 22 and liquid chromatography-mass spectrometry LC—MS assays 23 , can be used to detect chemical compositions to identify adulterant products.
However, none of these methods alone can definitively identify closely related species that share remarkably similar morphological characteristics and chemical profiles.
These techniques produce only indirect evidence of fraud and cannot definitively determine the identity of the given species. Therefore, there is an urgent need for rapid and simple identification procedures for the rapid inspection of raw herbal materials. DNA barcoding is a new molecular diagnostic technology that was first proposed by Canadian zoologist Paul Hebert in , and it identifies species by using a recognized standard, short genomic sequence DNA barcoding provides consistent and reliable results regardless of the age, plant part, or environmental factors of the sample Researchers can evaluate species information accurately by analysing DNA sequences.
This approach has been repeatedly reported in academic journals e.
Chen et al. These investigators suggested that the internal transcribed spacer ITS fails to be amplified and sequenced in most samples and that ITS2 is the most suitable locus for DNA barcoding research, followed by psbA-trnH as a complementary region There are more than three samples per species in this database The TCMD also contains the DNA barcoding standard operating procedure SOP and provides bioinformatics tools to assist in data analysis for researchers in the herbal identification industry.
In this study, we investigated the proportions and varieties of adulterant medicine in herb markets with the aim of protecting consumers from health risks associated with herbal product substitution and contamination by using a standard DNA barcoding method.
A total of raw herbal samples representing medicinal species were collected from the 7 primary markets in China. WordPress Shortcode. Published in: Full Name Comment goes here. Are you sure you want to Yes No. Be the first to like this.
