Overview
Acacetin is a bioactive flavone compound primarily extracted from plants such as black locust (Robinia pseudoacacia) and Turnera diffusa. As a secondary metabolite, it plays a role in plant defense mechanisms and has attracted significant scientific interest for its pharmacological potential. The compound's chemical structure features a 15-carbon skeleton with hydroxyl and methoxy functional groups that contribute to its biological activity. In traditional medicine systems, acacetin-containing plants have been used for centuries to treat various ailments. Modern research has validated some of these uses while uncovering new therapeutic possibilities. The compound is now studied for its effects on cellular pathways related to inflammation, oxidative stress, and cancer progression.
Physical and Chemical Properties
Acacetin presents as a yellow crystalline powder with a characteristic flavonoid structure. Its melting point ranges between 263-265°C, indicating moderate thermal stability. The compound demonstrates limited solubility in water but dissolves well in organic solvents like dimethyl sulfoxide (DMSO) and methanol, which is typical for flavonoid compounds. The flavone structure of acacetin features conjugated double bonds that absorb UV light, giving it potential as a natural UV-absorbing agent. Its chemical stability is maintained under proper storage conditions, though prolonged exposure to light, heat, or humidity may cause degradation. The methoxy group at the 4' position distinguishes acacetin from similar flavones and influences its biological activity.
Main Applications
In pharmaceutical research, acacetin serves as a lead compound for developing novel therapeutics targeting inflammation, cardiovascular diseases, and certain cancers. Studies suggest it may modulate various cellular signaling pathways, including those involving NF-κB and MAPK. The compound's antioxidant properties make it valuable for investigating oxidative stress-related conditions. The nutraceutical industry incorporates acacetin into dietary supplements, often standardized extracts from traditional medicinal plants. Some cosmetic formulations utilize its potential anti-aging and skin-protective effects. In agricultural applications, researchers explore acacetin's natural pesticidal properties as an alternative to synthetic chemicals.
Safety and Storage
Acacetin is generally considered safe at typical research and supplement doses, though comprehensive toxicological data remains limited. Standard laboratory precautions should be followed, including the use of gloves and protective eyewear when handling the powder form. Inhalation of dust should be avoided, and adequate ventilation is recommended during weighing procedures. For long-term storage, acacetin should be kept in airtight containers with desiccant packs, preferably under refrigeration (2-8°C) and protected from light. Under these conditions, the compound typically maintains stability for several years. Bulk quantities may require nitrogen flushing to prevent oxidation, especially for high-purity research-grade material.
B2B Procurement Guide
When sourcing acacetin, buyers should prioritize suppliers who provide comprehensive analytical certificates, including HPLC purity profiles (typically 95-98% for research use). The extraction method should be specified, as synthetic and plant-derived versions may have different impurity profiles. For pharmaceutical applications, documentation of residual solvents and heavy metals is essential. Price varies significantly based on quantity and purity, with research-grade material commanding premium prices. Consider requesting small test batches to verify quality before large purchases. Ethical sourcing is increasingly important, particularly for plant-derived acacetin, with some buyers preferring sustainably harvested raw materials. Lead times can vary from weeks to months depending on sourcing and purification processes.
