Biological Activities
Compounds
Conditions
Populus deltoides leaf extract demonstrates significant anti-inflammatory potential by treating lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. The extract specifically treats the LPS-triggered enhanced nuclear translocation of NF-κB p65 to modulate inflammatory signaling. Additionally, Populus deltoides treats proinflammatory tumor necrosis factor alpha (TNF-α) levels by reducing their concentration. It further treats the expression of inducible nitric oxide synthase (iNOS) within the cellular environment. Finally, this plant extract effectively treats nitric oxide (NO) production to limit inflammatory responses.
Preparations
Populus deltoides is prepared as a leaf extract to investigate its potential medicinal properties. This specific extract, referred to as PLE, is utilized to study anti-inflammatory activities in cellular models. Researchers focus on this preparation to observe how it inhibits inducible nitric oxide synthase and nitric oxide production. The preparation allows for the detailed examination of its ability to modulate the NF-κB and p38/JNK signaling pathways. Consequently, the use of the Populus deltoides leaf extract serves as the primary method for uncovering its biochemical mechanisms.
Parts used
Populus deltoides, commonly referred to as the eastern cottonwood, serves as a significant source of medicinal properties through its unique biological components. Specifically, the leaf of this species contains bioactive compounds that exhibit potent anti-inflammatory activities. Recent research indicates that an extract derived from the Populus deltoides leaf can effectively inhibit the production of nitric oxide and inducible nitric oxide synthase. This process is achieved by modulating critical signaling pathways, including NF-κB and the p38/JNK MAPK pathways. Consequently, the leaf extract demonstrates a promising ability to reduce proinflammatory markers within stimulated cellular environments.
