U W has one of largest _ herb gardens on earth . There is an herb garden on the University of Wa- terloo campus that may have a greater variety of mint, marjoram, savory, basil, thyme and other aromatic herbs than any otherinCanada. Dr. Morton can talk al- ‘most endlessly, and most fascinatingly. about the subject, about the many kinds of wild mints that Moreover, the green- houses on the north cam- pus where the herb garden is also located contain ad- ditional specimens of La- biatae . . . those from the tropics. Further, the UW herbarium in the biology 2 building has the largest collection of mint speci- means in Canada . . . un- doubted ly one of the larg- est in the world as well. Why the stress on mints? One reason is that mint has for many years been a particular interest of Dr. J.K. Morton. botanist and chairman of the depart- ment of biology. He's been into the mints since his undergraduate days at King's College. Newcastle upon Tyne. Some 800 members of the Labiatae family are to be found there. They have been introduced from all over the world - from North and South America, many parts pf Europe, Israel, Morocco, Kenya, West or Central Africa, Australia, India, Siberia, and elsewhere. More than 100 specimens of the mints - genus Mentha - are grown. Waterloo's Newest Industrial Mull " 564-576 Weber M.

F Lately he's been work- ing with Brian Lawrence, director of research for Stange Canada Ltd., a Toronto-based spice com- pany. Dr. Morton's acti- vities have been funded by the National Research Countil. Plants of the Labiatae family are most widely used in flavorings - in food, in candy, in tooth- paste, in liqueurs, and so forth. Many of them are also used in the manufac- ture of perfumes and medi- cines. "It may not generally be realized but the Produc- tion of Spearmint and pep- permint as cash crops runs into the millions of dollars annually, in the United States alone," he says. "and that country isn't the world's largest pro- ducer. though it is a major Some of the distilled oils from plants of the La- biatae family fetch more than $100 an ounce in the marketplace. While Dr. Mortdn con- cedes there are "economic implications" with respect to the research. his main concerns are "pure' l "We are primarily in- terested in classifying all the members of the Labia, "Our, function on this campus includes growing the ’herbs and collecting material for distillation of the oils. The analyzing is done by Mr. Lawrence and his ceworkers, using gas chromatography. Mr. Law- fence has specialized in this field and has develop- ed techniques which per- mit the analyses to be made using very small amounts of plant material." Dr. Morton says analys- ing these essences is a complex process. For in- stance, there are more than 60 different components in' distilled essence of pep- permint; there are more than 40 components, in the essence of one of the wild mints that grows in Canada. In the process of an- alysing these essences the researchers are finding substances never known before. Dr. Morton says that even though they are find- ing out more about the es- sences, this does not neces- sarily mean it will become economic to synthesize them. Nonetheless, know- ledge is being gained that may make it theoretically possible to do so. In the process, new flavorings, and potentially, new per- fumes and medicines are also being discovered. Dr. Morton and Mr. Lawrence have completed the survey of all the Cana- dian mints. tae family," he says. "This includes finding out how the family has evolved.
