By Hildebert K. M. Wagner (auth.), John T. Arnason, Rachel Mata, John T. Romeo (eds.)

Phytochemicals from medicinal crops are receiving ever larger recognition within the clinical literature, in medication, and on this planet economic climate quite often. for instance, the worldwide price of plant-derived prescribed drugs will achieve $500 billion within the 12 months 2000 within the OECD nations. within the constructing nations, over the counter treatments and "ethical phytomedicines," that are standardized toxicologically and clinically outlined crude medicines, are visible as a promising low­ rate possible choices in fundamental overall healthiness care. the sector additionally has benefited tremendously in recent times from the interplay of the learn of conventional ethnobotanical wisdom and the applying of modem phytochemical research and organic task reviews to medicinal crops. The papers in this subject assembled within the current quantity have been provided on the annual assembly of the Phytochemical Society of North the US, held in Mexico urban, August 15-19, 1994. This assembly situation used to be selected on the time of access of Mexico into the North American loose exchange contract as in a different way to have a good time the nearer ties among Mexico, the USA, and Canada. The assembly web site was once the old Calinda Geneve lodge in Mexico urban, a excellent website to host a bunch of phytochemists, because it was once the handle of Russel Marker. Marker lived on the lodge, and his well-known papers on steroidal saponins from Dioscorea composita, which introduced the contraception tablet, undergo the tackle of the hotel.
