The carotenoids are not only amongst the most widespread of the naturally occurring groups of pigments, but probably also have the most varied functions; witness their known roles in photokinetic responses of plants, in phototropic responses of fish and as vitamin A precursors in mammals and birds. Pigments with such wide distribution and such diverse functions are obviously of great interest to biological scientists with very different specializa tions, especially as it is unlikely that the study of the functions of carotenoids is anywhere near complete. The primary aim of the present work is to discuss the distribution, bio genesis and function of the carotenoids throughout the plant and animal kingdoms in such a way that, because of, rather than in spite of its bio chemical bias, it will be of value to workers interested in all the biological aspects of these pigments. The biochemical approach is considered the most effective because, generally speaking, most progress in the study of carotenoids in living material has been achieved using biochemical techniques, be they applied by zoologists, botanists, entomologists, microbiologists or other specialists; what is even more important is that a consideration of the present position makes it certain that further fundamental progress will also be made along biochemical lines.

In the mid-1960's, scientists working on carotenoids throughout the World agreed to have periodic meetings for the purpose of discussing and disseminating scientific research results concerning all aspects of carotenoids. The meetings were also organized to act as teaching forums for students, and the major scientific results from each meeting were to result in a publication. Each meeting was planned to be International in scope, being held in different locations in the World, and organized by local, recognized carotenoid scientists. The first of the Carotenoid meetings was held in Trondheim, Norway in 1966. Meetings then followed in Las Cuces, New Mexico (1969); Cluj, Roumania (1972); Berne, Switzerland (1975); Madison, Wisconsin (1978); Liverpool; England (1981); and Munich, Federal Republic of Germany (1984). In all of these meetings, the original purposes which stimulated the first meeting were accomplished: scientific discussion, student education and resulting scientific publication.The meetings and the i~formation resulting from them have led to significant advances in carotenoid biochemistry, biology, and chemisty. This publication represents the contributions from a distinguished list of participants. We look forward to the future meetings in this series.

Since the hypothesis of Peto et al. (1981) that beta-carotene might reduce the incidence of cancer, especially lung cancer, evidence has accumulated from observational studies that people who eat more fruit and vegetables, which are rich in carotenoids, and people having higher serum beta-carotene concentrations had lower rates of lung cancer. However, initial findings from two major clinical trials, ATBC (in Finland) and CARET (in USA), unexpectedly showed that supplemental beta-carotene alone or in combination with retinol appeared to increase the risk of lung cancer, especially among current or former smokers and/or in asbestos-exposed men. In December, 1997, a working group of international experts met in Lyon to evaluate the existing evidence on the cancer preventive activity of carotenoids. [IARC]

George Britton, Synnl/Jve Liaaen-Jensen and Hanspeter Pfander This book, Volume 2 in the series Carotenoids, is the first book to be published that is devoted entirely to the total synthesis of carotenoids, but it is timely in view of the rapid development and the growing diversification of the carotenoid field. The 1971 Carotenoids book contained a major chapter of 250 pages on total synthesis by H. Mayer and O. Isler. That comprehensive and authoritative review described systematically the construction of many synthons and the synthesis of many natural and unnatural carotenoids and related compounds. Twenty five years on, that chapter remains an essential reference work and source of information, with its extensive collection of tabulated data and lists of references to the original literature. Surveys of progress since 1971 have been presented at the IUPAC International Symposia on Carotenoids and are included in the published proceedings of these symposia. The history of major publications in the carotenoid field, leading to the development of this series, was outlined in the preface to the series published in Vol. IA. The general philo sophy outlined in that preface, with emphasis on practical guidance and the inclusion of worked examples of some of the most useful procedures, is maintained in Vol. 2. In kceping with this philosophy, Vol. 2 is not intended to be an exhaustive review of the literature, but is planned as a practical book, as well as a source of information.
