"The volatile constituents of Shi Mei (Rosa davurica Pall.) flower concrete have been investigated by a combination of chromatographic and spectroscopic methods. This essential oil possesses a characteristic plum-like and Osmanthus flower-like odour. The main constituents of the essential oil from Shi Mei flower concrete were eugenol (23.8%), benzyl alcohol (24.5%), β-ionone (7.0%), dihydro-β-ionol (3.3%), linalool (6.0%) and benzaldehyde (2.5%)." \\

"With antioxidants protection, consumptions of wild rose hips can reduce the risk of chronic diseases related to oxidative stress, such as aging, fatigue, cardiovascular and cerebrovascular diseases... EA [ethyl acetate] fraction revealed the highest total phenolic content and the strongest antioxidant ability in cyclic voltammograms (CV) and oxygen radical absorbance capacity (ORAC) assays. Moreover, the strongest inhibitory  activity against oleic acid-induced (OA-induced) fatty liver in vitro was also the EA fraction... The most active  fraction (EA-FII) of EA in all assays above, which mainly included catechin, quercetin-sedoheptulose  and quercetin-94, was identified by LC/MS, HPLC and ultraviolet (UV)/V spectrum analysis." \\
