  • Applications

    Ligustilide (CAS 81944-09-4) is a natural phthalide abundant in Angelica sinensis and Ligusticum chuanxiong, applied as a quality-control marker and reference standard for herbal materials, as a bioactive ingredient in drug discovery and nutraceutical research, and as a fragrance/flavor component; preclinical evidence indicates anti-inflammatory, antioxidant, neurovascular-protective, smooth-muscle–relaxant, analgesic, and circulation-modulating actions, supporting its use as a lead for potential indications such as cerebral ischemia, migraine, dysmenorrhea, and smooth-muscle spasm; in traditional-medicine manufacturing it supports standardization and pharmacopeial quantification of Dong quai/Chuanxiong extracts, while the fragrance sector leverages its warm herbal note for oriental/botanical accords in perfumes and food flavors; product development should account for its volatility and light/heat sensitivity (often requiring stabilization and delivery strategies) and comply with local safety/regulatory requirements, as most data remain in vitro or in animal models and do not substitute medical advice or regulatory approval.
