This volume is #525 in the American Chemical Society Symposium Series -- a collection of papers presented at a symposium sponsored by the ACS Division of Agricultural and Food Chemistry at the 203rd National Meeting of the ACS in San Francisco, California, April 1992. With the increased industry, consumer, and professional interest in essential oils and "aromatherapy," this volume will have particular application to those who have a technical interest in essential oils and other volatile compounds from plants. The presentations are decidedly chemical and technical in nature and not appropriate for general readership. The book is divided into three sections: Biogenesis and Biochemistry, Essential Oils, and Flowers. Included in the first section are several presentations on flavor and fragrance molecules that affect various insect species as well as the formation of some components of green tea against Streptococcus mutans. The essential oil section includes papers on Eucalyptus oils, Citrus oils, Spearmint oils, and a general paper on therapeutic properties of essential oils and fragrances. The final part on flowers deals with chemical analysis of numerous floral derived compounds, including the fragrant compounds from traditional medicinal plants such as German chamomile, Roman chamomile, valerian, and meadowsweet.
