Rosaceae family

Citronellol Manufacture. Citronellol is found widely in nature and in both optically isomeric forms. Prior to the development of synthetic citronellol, this alcohol was obtained from certain oils of the Rosaceae family or by hydrogenation of citronellal isolated from citronella oil. Citronellol has a floral odor resembling that of roses. 

Cassava, lima beans, linseed, bamboo sprout, macadamia nuts, hydrangea, Rosaceae family (plum, peach, pear, apple, bitter almond, cherry). Sorghum species (Johnson grass, sorghum, Sudan grass, arrow grass), Linum species (flax, yellow pine flax)... 

Where trees infested with tent caterpillars are available, they can be studied as they follow odor trails along branches or twigs of trees. Their odor trails along branches can be experimentally manipulated by interrupting, reversing, or covering them with other odors (Travis 2003). Look for apple trees or other members of the Rosaceae family in spring. 

Rose, Rosa canina L., also known as dogberry or hop fruit, is in the Rosaceae family. The fruit of this particular species of rose is generally used to prepare a stew. The seeds from Rosa canina L. were investigated for their chemical composition and nutritional values for medicinal purposes. Seed oils were prepared from fruits grown at three locations in Turkey and evaluated for their fatty acid composition (31). Linoleic acid was the primary fatty acid detected, which ranged from 48.6-54.4% of total fatty acids, followed by a-linolenic acid (16.4-18.4%) and oleic acid (14.7-18.4%) (Table 4). The seed oil contained approximately 85% total unsaturated fatty acids, indicating that Rosa canina L. seed oil may be an excellent source for unsaturated and essential fatty acids. 

The cherry tree Prunus avium L.) is a member of the Rosaceae family. Cherry seed contains about 18% oil on a dry weight basis (48). Significant levels of oleic acid were detected in the cherry seed oils prepared by hexane extraction using a Soxhlet apparatus. Oleic acid comprised 24—38% of the total fatty acids from three different varieties of cherry fruits (Table 7) (48). Linoleic acid was the major fatty acid in the cherry seed oil, and ranged 40 9% in the seed oil, along with ot-eleostearic (18 n-5), palmitic, stearic, arachidonic, and ot-linolenic acids (Table 7). alpha-eleostearic acid comprising 10-13% of cherry seed oil, is a conjugated... 

Compound 15 was first identified in Osmanthus asiaticus, a plant of Oleaceae family [15]. Compound 16 was isolated in Primus grayana, a plant of rosaceae family [16] and in Ricciocarpus natans, Ricciaceae [17]. Compound 17 was assumed to be present in O. europaea [18,19], on the basis of chromatographic considerations and was identified [14], together with 15 and 16[14], in carolea cultivar. 

Specific enzymes are obtained predominantly from the Rosacea family (almond, plum, cherry, apricot) and they have been thoroughly investigated [1537-1540]. They contain FAD in its oxidized form as a prosthetic group located near (but not in) the active site, but this moiety does not participate in catalysis and seems to be an evolutionary relict. 

Cyanogenic Glycosides Commonly present in plants of the Rosaceae family, and they are also present in sorghum and in cassava root, which are major sources of carbohydrates in Africa. 

The aucuparins appear to be significant constituents of only a limited number of genera and families and are therefore useful taxonomic markers. So far they have only been found in species belonging to the Rosaceae family. They are part of the defense system and are formed in response to infections or as a consequence of heartwood formation. Further members of this class of plant phenolics will certainly be found in the future. 

The bitter taste sometimes occurring in stewed sour cherries, plums and other stone fruits of the Rosaceae family is caused by the presence of cyanogenic glycosides, especially prunasin (see Section 10.3.2.3.1). Rowan berries, the fruit of rowan Sorbus aucuparia), which are used to make jam or jelly with a distinctive bitter taste, contain 3-hydroxy-5-hexanolide -D-glucoside (8-224). Enzymatic...
