Toralactone 9-O-β-D-gentiobioside

Toralactone 9-O-β-D-gentiobioside, also known as Cassiaside C or Toralactone-9-O-gentiobioside (CAS 119170-52-4, molecular formula C27H32O15), is a naturally occurring naphtho-alpha-pyrone glycoside isolated primarily from Cassia obtusifolia seeds. It carries no assigned E-code and is classified within the vitamins and nutrients category.

In food and nutrition applications, the compound functions as an antioxidant by scavenging free radicals and inhibiting lipid peroxidation, helping to extend oxidative stability in formulated products. In pharmaceutical and healthcare contexts, it is under investigation as a bioactive reference standard and functional ingredient, where its glycosidic structure influences bioavailability and cellular uptake mechanisms.

Toralactone 9-O-β-D-gentiobioside is supplied as a solid and is available in research and commercial grades suited to analytical and formulation use. Procurement should confirm REACH registration status and supplier documentation prior to import into the EU. Buyers are advised to request certificates of analysis specifying purity and botanical source.
