Role: 

Project Manager, Chinese Medicinal Plants Authentication and Conservation Centre (CMPACC)

Main activity is to build, research and manage Kew’s Chinese medicinal plants authentication and conservation resource (CMPACC). Aims are 1. to create and provide a medicinal plants authentication and plant names service to help improve the safe and efficacious use of Chinese medicinal plants in the West and promote their sustainable supply; 2. to research and support related natural product and regulatory needs appropriate to emerging international standards.

CMPACC’s work includes extensive fieldwork in China, creation of provenanced reference medicines at Kew, development of analytical identification methods (mostly chemical) and the provision of an authentication service to a wide audience in the UK and abroad, notably government regulators (health and conservation), hospitals, herbal medicine traders, practitioners, manufacturers, training colleges and academia. Main external collaborators are the Chinese Academy of Medical Science and the British Pharmacopoeia Commission. Activities are dependent upon close inter-departmental collaboration at Kew, such as the verification of voucher specimens by Herbarium taxonomists, chemical finger-printing by Jodrell Laboratory staff, managing science delegations from China often with the support of CLCE staff and more recently, plant names research with Kew’s recently funded Medicinal Plant Names Services (MPNS). Additional advice is provided to staff in the Conventions & Policies Section of HLAA regarding the status and identification of CITES-listed Chinese medicinal species in UK trade. Externally the work is represented in Kew’s official involvement in various international initiatives notably the EU Framework 7 project: ‘Good Practice in Traditional Chinese Medicine Research in the Post-Genomic Era’ and the ‘Consortium for the Globalisation Chinese Medicine’.

Staff management: 2 part-time. Their activities focus on economic botany enquiries and related research specialising in the identification and toxicology of UK plants and fungi.
