Personal profile

Paul Bremner has a particular interest in molecular and chemical authentication, including DNA fingerprinting and HPLC profiling of herbal medicinal products in the context of EU Directive 2004/24/EC which came into force in May 2011; and the impact on public health of medicinal herb use and the authentication of material sold.

Paul was also a Member (2008-2011) of both the Expert Group for Medicinal Plant Drugs at the European Pharmacopeia, Group 13B and the British Pharmacopeia on the Expert Advisory Group: Herbal and Complementary Medicines.

  • dc.title: The application of a DNA-based identification technique to over-the-counter herbal medicines dc.contributor.author: Kazi, Tazimuddin; Hussain, Nazreen; Bremner, Paul; Slater, A.; Howard, Caroline dc.description.abstract: Reliable methods to identify medicinal plant material are becoming more important in an increasingly regulated market place. DNA-based methods have been recognised as a valuable tool in this area with benefits such as being unaffected by the age of the plant material, growth conditions and harvesting techniques. It is possible that the methods of production used for medicinal plant products will degrade or remove DNA. So how applicable are these techniques to processed medicinal plant products? A simple PCR-based identification technique has been developed for St. John's Wort, Hypericum perforatum L. Thirteen St. John's Wort products were purchased including capsules, tablets and tinctures.DNA was extracted from each product, and the species specific PCR test conducted. DNA was successfully extracted from all thirteen products, using a fast and efficient modified method for extracting DNA from tinctures. Only four products yielded the full length ITS region (850 bp) due to the quality of the DNA. All of the products tested positive for H. perforatum DNA. DNA-based identification methods can complement existing methods of authentication. This paper shows that these methods are applicable to a wide range of processed products, provided that they are designed to account for the possibility of DNA degradation dc.description: Fitoterapia Available online 13 March 2013 In Press, Uncorrected Proof — Note to users The application of a DNA-based identification technique to over-the-counter herbal medicines Tazimuddin Kazia, Nazreen Hussaina, Paul Bremnera, Adrian Slaterb, Caroline Howardb, , a Leicester School of Pharmacy, Faculty of Health and Life Sciences, ذكذكتسئµ, Leicester, LE1 9BH, United Kingdom b Biomolecular Technology Group, Allied Health Sciences, Faculty of Health and Life Sciences, ذكذكتسئµ, Leicester, LE1 9BH, United Kingdom Corresponding author at: 1.15 Hawthorn Building, The Gateway, ذكذكتسئµ, Leicester, LE1 9BH, United Kingdom.
