Volatile ester formation in roses. Identification of an acetyl-coenzyme A. Geraniol/Citronellol acetyltransferase in developing rose petals.
The aroma of roses (Rosa hybrida) is due to more than 400 volatile compounds including terpenes, esters, and phenolic derivatives. 2-Phenylethyl acetate, cis-3-hexenyl acetate, geranyl acetate, and citronellyl acetate were identified as the main volatile esters emitted by the flowers of the scented rose var. "Fragrant Cloud." Cell-free extracts of petals acetylated several alcohols, utilizing a...
متن کاملEffects of dried Rose Petals (Rosa damascena) on the antioxidant capacity of Green and Black Tea
The health benefits of green and black tea are mainly associated with their antioxidant potential and phenolic compounds. The present study aimed to evaluate the effects of dried rose petals (Rosa damascena) on the antioxidant capacity of green and black tea. Antioxidant capacities of tea and rose infusions were assessed using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2-azinobis-3-<...
متن کاملChanges in the Physical State of Membrane Lipids during Senescence of Rose Petals.
Changes in the physical state of microsomal membrane lipids during senescence of rose flower petals (Rosa hyb. L. cv Mercedes) were measured by x-ray diffraction analysis. During senescence of cut flowers held at 22 degrees C, lipid in the ordered, gel phase appeared in the otherwise disordered, liquid-crystalline phase lipids of the membranes. This was due to an increase in the phase transitio...
متن کاملAntibacterial and Antifungal Activity of Rosa damascena MILL. Essential Oil, Different Extracts of Rose Petals
Rosa damascena petals were extracted by water, hexane and ethanol. The latter was further fractionated with chloroform, ethyl acetate and butanol. Rose oil and different petal extracts were evaluated against three fungi and eleven Gram-positive, Gram-negative and acid-fast bacteria. Rose oil and all extracts exerted broad spectrum antimicrobial activities against the tested organisms. The desce...
متن کاملGenome-Wide Association Analysis of the Anthocyanin and Carotenoid Contents of Rose Petals
Petal color is one of the key characteristics determining the attractiveness and therefore the commercial value of an ornamental crop. Here, we present the first genome-wide association study for the important ornamental crop rose, focusing on the anthocyanin and carotenoid contents in petals of 96 diverse tetraploid garden rose genotypes. Cultivated roses display a vast phenotypic and genetic ...
