The purpose of this paper is to give an overview of our intense synthetic efforts that have been expended in the quest for novel fragrance ingredients. Carbon-carbon bond formation is at the heart of organic synthesis. 1 Several examples will be presented, which will highlight the utility of diverse synthetic reactions such as Diels-Alder, Mannich, ene reactions, etc. that have been used to uncover highly desirable aroma chemicals (Iso E Super, Lyral, Triplal [or Aldehyde AA], Isocyclocitral and so forth; F-1).

Lavender oil (ex. Lavandula angustifolia Mill.) is produced commercially by a number of countries: France (the main supplier), Bulgaria, Moldova, Ukraine and Australia. The oils from each of these regions possess distinctive aroma characters, which range from the fine, flowery, fresh notes in the French oils to herbal, woody and camphoraceous with fatty notes in the Australian oils. Herein, it will be shown that these differences in aroma can be translated into a visual form (map) that assists comparisons with chemical analysis data.

Petitgrain or Citrus Leaf Oils In 1993, the composition of the range of petitgrain or the leaf oils of commercially important Citrus species were reviewed (Lawrence 1993). This current review will address the recent published literature and those studies that were not included last time. Each Citrus species will be treated separately.

What is the relationship between the market and fragrance development? Where are new scent concepts coming from? To find some answers we spoke with Givaudan junior perfumer Cecile Krakower about the role of innovation, cross-disciplinary studies, cultural exchanges and trend spotting in fragrance creation.

In part I of this cedarwood series (Perfumer & Flavorist, May/June 2001), we discussed various cedarwood oil types and derivatives. In part II of this cedarwood series (Perfumer & Flavorist, July/August 2002), we discussed the application of cedarwood and its derivatives in various types of fragrances. We have also given examples of the use of cedarwood in imitations of several essential oils, and of the use of cedarwood derivatives in some specialties.

Although up to 10,000 natural and synthetic aroma chemicals exist, the search for new or improved products is ongoing in the flavor and fragrance industry (F-1). The search for new substances starts with the analysis of the possible benefits, the existing knowledge and the routes that can be followed.

Geranium Oil In 1996, Zang et al. analyzed geranium oil of Chinese origin. Although they found that some of the major constituents were citronellol (24.73%), geraniol (8.79%) and linalool (4.16%), the authors misidentified many of the other constituents; however, it is included in this review for completeness. Möllenbeck et al. (1997) analyzed a sample of geranium oil produced in Madagascar. The oil composition was found to be as follows:
