Rosa laevigata fruit has been known as a functional foodstuff for a long time. Recently, increasing attention has been given to polysaccharides from R. laevigata fruit due to their numerous medicinal and nutritional properties. In this study, a rapid and effective approach for the extraction and
BACKGROUND
Rosa laevigata Michx. (Rosaceae), widespread in China, contains many valuable nutrients and has long been used as food and medicine in Chinese folklore. Nowadays, due to its favorable property of coloring, the brown pigment of R. laevigata has an attractive potential as an available
Wines made from 3 spine grape (Vitis davidii Foex) genotypes-Junzi 1# (JZ 1#), Junzi 2# (JZ 2#), and Liantang (LT)-and Cherokee rose (Rosa laevigata Michx., CR) were evaluated for their phenolics composition and antioxidant activities by several assays, including
The total flavonoids (TFs) from Rosa laevigata Michx fruit showed hepatoprotective and antioxidant activities. However, the safety of this natural product has not been investigated. In the present paper, a 90-day subchronic toxicity study was conducted, and the tested TFs was orally administered to
The effect of the total saponins from Rosa laevigata Michx fruit (RLTS) against acetaminophen (APAP)-induced liver damage in mice was evaluated in the present paper. The results showed that RLTS markedly improved the levels of liver SOD, CAT, GSH, GSH-Px, MDA, NO and iNOS, and the activities of
We investigated the effects of an extract of Radix Rosa laevigata (R. R. laevigata) on Propionibacterium acnes (P. acnes) and lipopolysaccharide (LPS)-induced acute liver injury. The plasma alanine aminotransferase (ALT) activity was significantly elevated by an intravenous injection of heat-killed
Diabetic nephropathy (DN) is a long-term complication of diabetic mellitus. Numerous reports have suggested that oxidative stress is defined as the excessive production of reactive oxygen species (ROS) surpassing existing anti-oxidative defense mechanisms, and plays a critical role in the
Protective effect of the total flavonoids (TFs) from Rosa laevigata Michx fruit against carbon tetrachloride (CCl4)-induced hepatotoxicity in mice was investigated. Pretreatment with TFs significantly decreased CCl4-induced elevation of serum aspartate transaminase (AST) and alanine transaminase
The neuroprotective effect and mechanism of the flavonoid-rich extract (FRE) from Rosa laevigata Michx fruit on cerebral ischemia-reperfusion (I/R) injury were investigated. The contents of flavonoids, saponins and tannin were determined, and ten chemicals including chlorogenic acid,
