Chemical Composition of Rose Water Volatiles

Abstract

A volatile concentrate obtained from rose water (ex. Rosa damascena fl owers) by liquid-liquid extraction with dichloromethane was studied by GC and GC/MS. The volatiles consisted mainly of 2-phenylethanol (69.7-81.6%), linalool (1.5-3.3%), citronellol (1.8-7.2%), nerol (0.2-4.2%), geraniol (0.9-7.0%) along with rose oxides and all other characteristic minor rose compounds.

Hydrosols of orange blossom ( Citrus aurantium ), and rose flower ( Rosa damascena and Rosa centifolia ) support the growth of a heterogeneous spoilage microbiota

“…The major compounds in the samples analyzed in this work, i.e., linalool and α-terpineol in orange blossom hydrosols, 2-phenylethanol, citronellol and geraniol in both rose sp. hydrosols, were also in high amounts in hydrosols analyzed in previous studies, and variations in 6-methyl-5-hepten-2-one, linalool, α-terpineol, citronellol, geraniol, and 2-phenyl ethanol amounts among samples for example were also previously reported (Agarwal et al, 2005;Aslam Khan & Shoaib Ur, 2005;Jeannot et al, 2005;Mahboubifar, Shahabipour, & Javidnia, 2014;Ulusoy et al, 2009; Albert Vieille SAS unpublished data) ( Table 2). The major compounds contained in the EO phase of rose and orange blossom hydrosols are known for their antimicrobial properties.…”

Fast Quantification of Phenylethyl Alcohol in Rose Water and Chemical Profiles of Rose Water and Oil of Rosa damascena and Rosa rugosa from Southeast China

“…It was noted that percentages of phenylethyl alcohol in rose water volatiles investigated were comparable to those from Indian [3,[10][11] , Iranian [12] and Turkish [13][14] rose waters. Rose water is valued for high levels of phenylethyl alcohol, which is responsible for the characteristic aroma of fresh rose flowers [10][11][12] . In contrast, the percentages of phenylethyl alcohol in rose oils were much lower (< 1.6%, Table 1).…”

“…Numerous studies have been carried out on chemical composition of rose oil [2][3][4][5][6][7][8][9] and water [3,[10][11][12][13][14] from different countries. Literature survey revealed that there is no chemical investigation on rose water volatiles of R. damascena and R. rugosa from Southeast China.…”

Volatile Oil Constituents of Rosa canina L.: Quality As Affected by the Distillation Method

“…By using the latter technique (SWE), two years earlier,Özel and Clifford [6] reported that the essential oil of R. canina was mainly dominated by 2-phenethyl alcohol and benzyl alcohol. Volatile oil samples of R. damascena from India [21], France [22], and Iran [13] extracted by using liquidliquid extraction of the aromatic water, head-space, and hydrodistillation methods showed an aromatic profiles dominated by alcohols mainly 2-phenylethyl alcohol, citronellol, nerol, and geraniol, respectively. Another report from India reported that the essential oil obtained by the distillation of fresh flowers of R. damascena was dominated by alcohols (55.25-83.41%) with 2-phenethyl alcohol being the main constituent [18].…”
