Natural ingredients have long been utilized to enhance human health. While Rosa rubiginosa L. has been relatively understudied, it is known for its antioxidant and anti-inflammatory properties. This study explores its diverse bioactivity on human primary keratinocytes and fibroblasts, highlighting its potential as a bio-functional agent in cosmeceuticals or nutraceuticals. The Rosa rubiginosa L. leaf extract demonstrated strong scavenging activity and high phenolic content protection while also preventing DNA breakage. At the molecular level, ATP determination revealed that the Rosa rubiginosa L. leaf confers cell viability even under oxidative stress. Gene expression analysis uncovered its protective effects on human primary keratinocytes and fibroblasts due to its strong antioxidant and anti-inflammatory response under oxidative stress induced by UVA irradiation. These findings suggest that Rosa rubiginosa L. leaf extract provides significant in vitro biological properties in cell-based models, offering new insights into its potential benefits and underscoring its bio-functional role.

Rosehips (Rosa spp., Rosaceae) are wild rose bushes with more than 100 species. Its fruits vary in colour and size, depending on the species, and are recognised for their nutritional characteristics. Ten samples of Rosa canina L. and Rosa rubiginosa L. fruits were collected at different geographical points from Southern Chile. Nutrients such as crude protein and minerals and functional properties such as phenolic compounds, ascorbic acid, and also antioxidant activities were evaluated by HPLC-DAD-ESI-MS/MS. The results revealed a high content of bioactive compounds, primarily ascorbic acid (6.0 to 8.2 mg g−1 fresh weight (FW)), flavonols (427.9 ± 0.4 μg g−1 FW) and antioxidant activity. We established a relationship between the antioxidant activity using Trolox equivalent antioxidant capacity (TEAC), cupric reducing antioxidant capacity (CUPRAC) and 2,2-diphenyl radical (DPPH) methods and the concentration of uncoloured compounds, such as flavonols and catechin. This antioxidant activity was primarily associated with the samples from Gorbea, Lonquimay, Loncoche, and Villarrica localities, and all of them were of the species Rosa rubiginosa L. The results here obtained represent novel information of rosehip fruits. In this sense, the reported information about compounds and antioxidant activities in rosehip fruits allowed us to continue new lines of research in relation to the potential formulation of new functional foods and also in the treatment and/or prevention of some diseases.

The Egyptian narrowly endemic and critically endangered plant species Rosa arabica Crép. was studied employing a taxonomic and molecular approach. Morphological investigations, distance analysis, and phylogenetic reconstruction revealed that R. arabica is a distinct species with great affinity to R. canina and differentiated from R. rubiginosa. Molecular identification based on the sequences of multiple markers single or in combination ITS, matK, rbcL, and trnL-F succeeded in identifying R. arabica at genus and species levels. We evaluated the potential of each marker and a combination of the nuclear ITS -Internal Transcribed Spacer- with one of the plastid markers, matK, rbcL, or trnL-F, to accurately identify Rosa species. All of them were successful in identifying R. arabica. Classification based on DNA sequences shows that R. arabica is placed within section Caninae in a clade comprising R. canina and R. rubiginosa. Moreover, R. arabica is closely related to other European Rosa species. In conclusion, our results indicate that the four DNA markers can provide species resolution in the context of the genus Rosa and relatives, aiming to characterize morphology and genetic diversity in the ecological and economically important genus Rosa.
