Rosa davurica Pall., Rosa rugosa Thumb., and Rosa acicularis Lindl. Originating from Far Eastern Russia: Screening of 146 Chemical Constituents in Three Species of the Genus Rosa

Abstract

Rosa rugosa Thumb., Rosa davurica Pall., and Rosa acicularis Lindl. contain a large number of target analytes which are bioactive compounds. High performance liquid chromatography (HPLC), in combination with the ion trap (tandem mass spectrometry), was used to identify target analytes in MeOH extracts of R. rugosa, R. davurica, and R. acicularis, originating from the Russian Far East, Trans-Baikal Region, and Western Siberia. The results of initial studies revealed the presence of 146 compounds, of which 115 were identified for the first time in the genus Rosa (family Rosaceae). The newly identified metabolites belonged to 18 classes, including 14 phenolic acids and their conjugates, 18 flavones, 7 flavonols, 2 flavan-3-ols, 2 flavanones, 3 stilbenes, 2 coumarins, 2 lignans, 9 anthocyanins, 3 tannins, 8 terpenoids, 3 sceletium alkaloids, 4 fatty acids, 2 sterols, 2 carotenoids, 3 oxylipins, 3 amino acids, 5 carboxylic acids, etc. The proven richness of the bioactive components of targeted extracts of R. rugosa, R. davurica, and R. acicularis invites extensive biotechnological and pharmaceutical research, which can make a significant contribution both in the field of functional and enriched nutrition, and in the field of cosmetology and pharmacy.
