action | the active ingredient of pokeweed saponin has many pharmacological effects such as anti-inflammatory, immune enhancement, anti-tumor and so on, with pokeweed saponin a having the highest content. |
application | pokeweed saponin a has anti-inflammatory, anti-apoptosis and anti-tumor cell proliferation effects in a variety of acute and chronic models. Pokeweed saponin A can alleviate LPS-induced acute lung injury by inhibiting the production of inflammatory factors, and at the same time can reduce the release of NO caused by LPS. In addition, as an Nrf2 activator, pokeweed saponin A inhibits oxidative stress and thus inhibits allergic airway inflammation, then pokeweed saponin A, as a potential antioxidant, also has a certain alleviating effect on other oxidative stress-related diseases. |
biological activity | Esculentoside A (EsA), a triterpene saponin isolated from the root of pokeweed Phytolacca esculenta. Esculentoside A (EsA) has anti-inflammatory activity and selective inhibitory activity on cyclooxygenase -2 (COX-2). Esculentoside A (EsA) inhibits inflammatory response in LPS-induced acute lung injury (ALI) by inhibiting (NF-KB) and mitogen-activated protein kinase (MAPK) signaling pathways. |
