Common Names: chestnut rose, Chinquapin rose
Researchers developed an antifungal film using fermented walnut meal to preserve Rosa roxburghii Tratt. Ultrasonic treatment improved film properties and reduced microbial growth, offering a sustainable solution for food packaging.
Scientists found a polysaccharide in Rosa roxburghii that could help fight cancer. It inhibits tumor growth, suppresses angiogenesis, and activates the immune system. Potential for cancer treatment.
Study found solid-state fermentation released more bound polyphenols from fruit pomace dietary fiber compared to alkaline extraction, with higher antioxidant and α-glucosidase inhibitory activities. SSF can be a valuable method for efficient release of bioactive compounds from food waste.
Researchers found that polyphenols from Rosa roxburghii Tratt plant can prevent and treat acute lung injury (ALI) in mice by regulating gut microbiota. This suggests the potential of using functional foods to alleviate ALI and improve gut health.
Scientists sequenced the genomes of Rosa roxburghii and Rosa sterilis to understand their hybrid origin and absence of recent whole-genome duplications. They found that duplicated genes may contribute to flavonoid accumulation and identified key regulatory genes for ascorbate synthesis. Terpene synthase genes may be involved in terpenoid biosynthesis. This study sheds light on genome evolution and the molecular basis of high ascorbate concentration in these Rosa species.
Extracted from Rosa roxburghii Tratt fruit, polysaccharides RP1 and RP3 induce apoptosis of breast cancer cells. Potential for functional foods or pharmaceutical products for breast cancer treatment.
Researchers developed a compound called RC-SeNP which effectively inhibits the growth of pathogens on apples, shows high antioxidant activity, and preserves fruit quality. It also has no toxicity and can potentially be used in sustainable agriculture.
Wild RRT juice from different altitudes improved glucose and lipid metabolism disorders and oxidative damage in type 1 diabetes mellitus (T1DM) mice, possibly due to activation of the PI3K/Akt pathway. The most effective group was medium altitude.
Rosa roxburghii can improve insulin resistance in obese rats by reducing oxidative stress and increasing the expression of certain proteins and genes. This may be related to the PI3K/Akt2/GLUT4 signaling pathway.
