Alisol A is a protostane-type triterpenoid compound isolated from the rhizomes of Alisma orientalis, a plant used in traditional Chinese medicine (TCM). It is widely recognized for its potential therapeutic applications, particularly in TCM formulations. It is primarily studied for its hepatoprotective effects, making it valuable in supporting liver health and treating liver-related disorders such as hepatitis and liver fibrosis. Research has shown that Alisol A exhibits anti-inflammatory and anti-fibrotic properties. Additionally, it has been investigated for its role in lipid metabolism, where it may aid in reducing cholesterol levels and preventing atherosclerosis. Alisol A also demonstrates anticancer potential by inducing apoptosis in certain cancer cells, including hepatocellular carcinoma, making it a subject of interest in oncology research. Furthermore, its antioxidant properties contribute to its ability to mitigate oxidative stress, which is beneficial in combating various chronic diseases. As a research reagent, Alisol A is used in pharmacological and biochemical studies to explore these bioactivities.
