Bulgarian rose oil

CnHigO, Mr 190.28, is a constituent of Bulgarian rose oil, to the flavor of which it contributes an important role although it is only present at a concentration of 0.05%. 

Two major species are used for oil production Rosa damascena, which yields rose otto, Bulgarian rose oil and Turkish rose oil and Rosa centifolia, which yields French rose oil or Moroccan rose oil. There are also many different subspecies. 

The rose ketones 11, first discovered ini970 [gl] in Bulgarian rose oil, and named damas-cones, show unique organoleptic properties. Because of this they have elicited great interest, also as target molecules for new synthetic methods. a-Damascone 12 possesses a quite unique fruity odor, and its utilization aliows the creation of perfumistic notes otherwise difficult to achieve. 

Another new aldehyde was recently isolated from the oil of Rosa damascena (Bulgarian rose oil), and shown to be menth-l-en-9-al, a mixture of both diastereo-isomers (152) and (153) being present in the natural product. By oxidation of the hydroboration products of (+)-limonene (111) (see also ref. 109), both... 

Vomifoliol (97) isolated from Rauwolfia vomitoria appears to be a degradation product of abscisic acid and possibly a precursor of theaspirone. Damas-cenone, a minor component of Bulgarian rose oil, was shown to be the cross-conjugated isomer (98) of dehydroionone. A tetrahydro-damascenone was prepared by treating a-ionone-7,8-oxide with hydrazine. ...

CnH.gO, Mr 190.29, oil, bp. (1.7 kPa) 116-118°C. Component of Bulgarian rose oil, obtained from Rosa damascena. /3-D. is only present to 0.05% in this oil but is mainly responsible for the rose-like fragrance. j8-D. is an essential component of perfumes and gives them fresh and brilliant notes. 

The Damask rose (Rosa damascena) is also known as the "Rose of Kazan lak" (a town in Bulgaria), and since the 17th cen Wry it has been the source of Bulgarian rose oil.

One of the most important discoveries recently made in the field of carotenoid aroma compounds relates to the class of damascones. Seven naturally occurring members (266) to (272) of this class are known today. The discovery of these new compounds started with the isolation of damascenone (268) from Bulgarian rose oil in 1970 120). Later, the same compound was detected in various tobacco brands 5, 110, 306), tea 491), raspberry oil 708), cooked apples 442), various grape and wine varieties 546, 549), beer 598), coffee oil 179), buchu leaf oil 283) and Roman camomile 638). 3-Hydroxy-(3-damascone (269) was shown to be an important aroma component of tobacco 108, 169, 285) in which it develops a green, rose-floral and sweet Burley-like note (556). (3-Damascone (267) was found in Burley tobacco 110) and rose oil 108), whereas a-damascone (266), accompanied by (3-compound (267) and damascenone (268), was exclusively observed in tea oil 491). Among the known cyclization products (270) to (272), the last two compounds were found in tobacco (779), while ketone (270) was detected in tea 491). 

P-Damascenone (343) is present in Bulgarian rose oil at a level of only 0.05%, but is a major contributor to the overall odor of the oil. Not surprisingly, it is used in reconstitutions of rose oil. It is also found in rose, apricot, beer, grape, mango, tomato, wine, rum, raspberries, passionfruit, and blackberries. Its detection threshold is one-tenth those of a- or p-damascone.

Rose oil when added to the food has been reported to have choleretic effects on cats. Bulgarian rose oil has been reported to decrease urinary corticosteroids and serum ceruloplasmin, as well as elicit other effects on laboratory animals when administered intraperitoneally or intravenously. ...
