What are the pharmacological activities of Rosa laevigata?
This plant has anti-inflammatory, anti-tumor, antioxidant, hepatoprotective, and immunomodulatory pharmacological activities. Its rich concentration of bioactive compounds helps neutralize free radicals to prevent cellular damage. These properties work together to suppress excessive immune responses and reduce systemic inflammation. Furthermore, the plant exhibits significant potential in protecting liver cells from chemical toxicity. Researchers are also investigating its ability to inhibit the growth of malignant cells during tumor progression.
According to a study published by "Nutrients", total flavonoids (TF) from Rosa laevigatata Michx fruit demonstrate potent effects against hepatic ischemia/reperfusion (I/R) injury in a 70% partial hepatic warm ischemia rat model. These flavonoids decreased serum activities of aspartate transaminase (AST), alanine aminotransferase (ALT), myeloperoxidase (MPO), and lactate dehydrogenase (LDH). The treatment significantly decreased malondialdehyde (MDA) while increasing levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) to alleviate oxidative stress. Furthermore, TF downregulated the gene levels of inflammatory factors including interleukin-1 beta (IL-1β), interleukin-1 (IL-6), and tumor necrosis factor alpha (TNF-α). This hepatoprotection was achieved through the inhibition of the TLR4/MyD88 pathway and the activation of the Sirt1/Nrf2 signaling pathway.
The primary pharmacological activities of this plant are shown in the list below.
- anti-inflammatoy effect
- anti-tumor activity
- antioxidant activity
- cardiovascular protective
- hepatoprotective
What medicinal compounds this plant contains?
