The book on Essential Oils By Ernest Guenther, comes in six volumes. The first volume deals with the chemistry, history, biological origin and other functions of the essential oils along with its methods and analysis. The second volume describes the chemical components of this product and the rest of the volumes deal with individual oils, their origin, methods of production and their other properties.

Terpenoids play an important part in all our lives, from Vitamin A and hormones to perfumes and pharmaceuticals. This book provides an introduction to terpenoid chemistry.
Terpenoids play an important part in all our lives, from Vitamin A and hormones to perfumes and pharmaceuticals. This book provides an introduction to terpenoid chemistry, concentrating on the lower terpenoids, but the basic principles taught are also the foundation for the chemistry of the higher terpenoids. Coverage includes: the biogenesis of terpenoids; some of the history of the field; the principles of structural determination; and the importance of stereochemistry and stereoselective synthesis. Carbocation chemistry is introduced, as are the principles of total and partial synthesis. Finally, industrial chemistry (both discovery chemistry and chemical process development) is discussed, using the volatile terpenoids of perfumery to illustrate basic concepts. Ideal as both an introduction to terpenoid chemistry and as a refresher course, A Fragrant Introduction to Terpenoid Chemistry, with its real-life problems and appreciation of the relevance of chemistry to everyday life, will prove invaluable to students, lecturers and industrialists alike.

Solution to Problems
Lipids are insoluble in water; hence, they are a part of the main structural elements of protoplasm. Lipids and lipid–protein complexes provide the building of superficial membranes of cells and cell organs: nucleus, mitochondria, ribosomes et al. Being in the composition of membranes, lipids take part in the process of active transportation of ions and molecules through membranes. Also, neutral lipids are sources of energy.
Characteristic components of essential oils are terpenes, which differ from fatty oils, becouse they do not contain glycerides of fatty acids. Some of the essential oils contain saturated and unsaturated aliphatic, aromatic, terpene, sesquiterpene, monoand bicyclic hydrocarbons, and their oxygen derivatives – alcohols, aldehydes, ketones, esters, ethers of acids, lactones, and oxides – and also heterocyclic compounds. Fatty and essential oils have been known for a long time. In ancient Egypt, plant oils were used not only in food but in medicine, cosmetics and essential oils in perfumery.
Many scientists have taken part in research of lipids and essential oils: Claude-Joseph Geoffroy, C.W. Scheele, M.E. Chevreul, J.J.E. Poutet, A.M. Zaitsev, S.A. Fokin, A. M. Goldovskii, G.V. Pigulevskii, K. P. Kardishev, S. L. Ivanov, Gildich, Kaufmann, Coleman, Alen, Karta, Datton, Hofman, Brokenhoff, Yakobashvili, Voitsechovich, Shlyapnikov, Basher, Wulfson, and others. Moreover, studies on the composition and structure of lipids, lipophilic components and essential oils have been carried out by scientists of the Yunusov Institute of Plant Substances of the Academy of Sciences of the Republic of Uzbekistan since 1961. They studied lipids and the lipophilic components of vegetative and generative organs of more than 1.500 plants.
Essential oils are located in the flowers and leaves of plants and citrus fruits. More generally in plants, lipids are most often concentrated in the seeds and fruits.
Quantities and composition of lipids, lipophilic components and essential oils vary widely and depend on the region where the plant grows, type of plant, environmental conditions, level of salt in soil, etc. In animals and fishes fat concentrates in and under the skin and in fatty tissues or in tissues surrounding internal organs, and participates extremely actively in the vital functioning of the organism (heart, kidney, intestines, etc.). Glycerides of fatty acids and phospholipids are in the brain and nervous tissues.
Lipids, lipophilic components and essential oils are widely used in the food industry, pharmacy, engineering, perfumery and cosmetics, for the production of lacquers and pigments, etc.
In this work, lipids, lipophilic components and essential oils are characterized based on the plant families where they were found. In creating this handbook, special attention was paid to Russian literature that is often not readily available to international scientists.
This reference work is aimed at wide use by researchers and specialists workingwith lipids and essential oils in bioorganic chemistry, medicine, the food industry,pharmacy, fragrances, cosmetics, agriculture, and other industries.
