THE ESSENTIAL OILS Vol. II

---

In the course of the last century, hundreds of organic compounds have been identified among the natural compounds of essential oils. Some of these compounds are extremely rare, having been found in only one oil; others are common, and have been observed in a number of oils.

The task of the scientist in the field, whether he be a research worker or a laboratory analyst, has naturally increased in difficulty as the number of such compounds has mounted and information about them has swelled the literature on the subject. More and more of the chemist's time must now be spent on preliminary searches of such literature before he can undertake his own creative work.

The present volume, the second in a series on THE ESSENTIAL OILS, repre- sents an attempt to eliminate at least some of the tedious "spade-work" necessarily performed by the essential oil chemist. To this end, data on several hundred of the most important natural constituents of essential oils have been assembled into one volume, in the form of monographs, and brought as nearly up-to-date as possible. The structural formulas, occurrence, methods of isolation and identification, and physico-chemical properties of these compounds have been described. Succeeding volumes of this series will deal with individual essential oils and their chemical composition, and frequent reference will be made to the monographs contained in this volume.

A secondary aim of the present work is to stimulate further research in the field, particularly on essential oils of which the chemical composition is, so far, either only partially elucidated or entirely unknown.

The task of writing this book has been a complicated one, requiring years of work-a result, among other things, of the confusion existing in older literature, particularly in regard to stereoisomeric compounds. The diffi- culties of compiling material for the volume compounds. The diffi- culties of compiling material for the volume were further increased by the fact that during the Second World War scientific literature from continental Europe, the U.S.S.R., Japan and other parts of the world was not available. Even today much of it is accessible only in abstract form-through "Chemical Abstracts," for example.

For some of the older data presented in this work, the authors are indebted to Gildemeister and Hoffmann's classical work, "Die Ätherischen Öle," Third Edition, as a point of departure. Even where this is so, however, original references quoted in their work have been verified, and the material has been carried up-to-date
