The higher aliphatic alcohols, from octyl alcohol upwards, have-recently been introduced as perfume materials with considerable success. Only one or two of them, such as nonyl and undeeylenic alcohols, have so far been detected as natural constituents of essential oils, but other members of the series are prepared artificially, and are employed in minute quantities in the preparation of perfumes with characteristic, fruity bouquets. These alcohols are greatly diminished in perfume value by traces of impurities. According to H. J. Prins, the first interesting member of the series is octyl alcohol it has a very sweet, rose-like odour, and is especially suitable for giving a rose perfume that pecnliar sweet smell which distinguishes a rose from a rose perfume. This feature of the aliphatic alcohols diminishes in the series from Cg to Cjg. 

Palmarosa oil is obtained by steam distillation of wild or cultivated Cymbopogon martinii (Rox.) W. Wats. var. motia, collected when in blossom. It is a pale yellow liquid with a characteristic rose-like odor and a grassy note. 

Phenylethanol has a rose-like odour and makes the chemically produced compound the most used fragrance chemical in perfume and cosmetics, with a world market of about 7,000 t year [107, 108]. 2-Phenylethanol is also found in many foods as a characteristic flavour compound rounding off the overall aroma, especially in foods obtained by fermentation, such as wine, beer, cheese, tea leaves, cocoa, coffee, bread, cider and soy sauce [109]. In food applications, natural 2-phenylethanol is preferred rather than its nature-identical counterpart from chemical synthesis and it has a market volume of 0.5-11 year . This product is sold at market prices of up to US 1,000 per kiklogram and is mainly produced by yeast-based bioprocesses since its isolation from natural sources, e.g. rose oil, would be too costly [109].

Geranyl acetate (trans-3,7-dimethyl-2,6-octadien-1-yl acetate) Found in many essential oils including geranium, citronella, lavender, petitgrain and sweet marjoram. Fruity, floral, fresh, rose-like odour.

Hanseniaspora guilliermondii can produce more ethanol than Hanseniaspora uvarum and has a better balance of volatile and non-volatile compounds, including production of 2-phenylethyl acetate, which elicits a fruity, honey, rose-like aroma (Table 8D.6) (Rojas et al. 2003 Swiegers et al. 2005). Cofermentation with Saccha-romyces cerevisiae has potential for aroma enhancement of wine.

A derivative of fluorescein is important as a dye. It is known as eosine from the Greek word for dawn because its color is a fluorescent rose like the color of the sky at dawn. It is used as a silk dye. It is the tetra-hromine derivative of fluorescein potassium salt. 

Figure 2 depicts the variation of Scanning Electron Micrographs with crystallization time at different temperatures. At the beginning of the crystallization, the texture of obtained solid phase can be described as an agglomeration of fibrous (Fig. 2a, 2b, 2d). The 110 and 200 reflections are not present in the XRD pattern at this moment. When those reflections appear, the morphology characteristic of MCM-41 described by Tanev et al [6] or Elder et al [12] is detected (Fig,2e, 2f, 2h, 2j). Crystals have variable size and form and very porous surface. Finally when the triphasic mixture composed of hexagonal MCM-41, lamellar MCM-50 and amorphous phase is detected (Fig. 2i, 2k, 21), crystals with a sandy-rose like structure and spheric grains are clearly observed. The sandy-rose crystals belong to the MCM-50 lamellar structure [13] and the spheric grains correspond to the amorphous silica phase. The presence of MCM-50 and amorphous silica is proved by XRD patterns.

Group 4 lists compounds with leaf-like notes such as (Z)-3-hexen-l-ol (Flavis 02.056, FEMA 2563) and (Z)-3-hexenal (Flavis 05.075, FEMA 2561) as well as esters such as citronellyl acetate (Flavis 09.012, FEMA 2311) with rose-like, floral profile. 

One of the first researchers to study the aroma formation during the Maillard reaction was Ruckdeschel [21] in 1914. He described the reaction product of glucose with phenylalanine as rose-like, with leucine as bread-like, with valine as fine roasted and with alanine as similar to coloured malt. 

Stringer and McKie mention in their introduction above that our species "rose like a phoenix from a crisis which threatened its very survival," and propose later on in the book the occurrence of a population bottleneck sometime about 100 to ISOKa. The possibility of such a bottleneck has also drawn criticism from defenders of the orthodoxy, yet again the genetic evidence is what has come to the forefront to support the proposal.
