Role
Use of mass spectrometry to study plant chemical diversity.
Responsible for the development of mass spectrometry in the Jodrell Laboratory in the analysis of ‘small molecules’ in plants. Techniques utilizing mass spectrometry are fundamental to Kew's research in systematic phytochemistry, natural product discovery and the chemical authentication of plant extracts or products, and also contribute to many studies on the sustainable uses of plants and answering enquiries. Current instrumentation comprises a high resolution liquid chromatograph–hybrid ion trap/orbitrap mass spectrometer, a liquid chromatograph–quadrupole mass spectrometer and a gas chromatograph–quadrupole mass spectrometer with thermal desorption capability. Systematic phytochemical applications are being undertaken in Leguminosae, monocots, Malpighiales, Myrtaceae and Lamiaceae in collaboration with taxonomists and phytochemists at Kew and from other institutions. Chemical authentication of plant extracts or products focuses on issues arising from plants or extracts being traded in the UK, while enquiries are often concerned with poisoning cases.
Also responsible for producing Kew Scientist and the more specialist Science & Conservation News stories on the Kew website.
