Abstract

Feverfew (Tanacetum parthenium (L) Schultz Bip) is a medicinal plant that has come to prominence recently as a prophylaxis for migraine. The intent of this thesis was to develop standards for the proper identification and production of high quality feverfew products for the herbal industry. A comprehensive botanical standard has been developed based on: the floral morphology of five varieties, and trichome characterization, chromosome number, and microscopical analysis of dried leaf samples of wild-type feverfew. Parthenolide levels in leaf tissue remained constant after freeze-drying or oven-drying at three temperatures (30\sp∘, 35\sp∘, 40\sp∘C) and these levels fluctuated seasonally. Micropropagation of axillary shoots is a viable method for propagating and maintaining clonal populations. Rooting response was improved when macro-salts were reduced to half-strength and if agar was used as a gelling agent. However no improvement was shown if synthetic auxin was added to the medium, indicating that endogenous auxin was not limiting.
