Aucubin Specification

The Aucubin, with the CAS registry number 479-98-1, is also known as β-D-Glucopyranoside,(1S,4aR,5S,7aS)-1,4a,5,7a-tetrahydro-5-hydroxy-7-(hydroxymethyl)cyclopenta[c]pyran-1-yl. It belongs to the product categories of Iridoids; Natural Terpene Standards Chemical Class; Other Chemical Class; Oxygen containing Chemical Class; Alcohols; Alphabetic; AR to AZ Chromatography; Heterocyclics; Life Sciences Standards; Natural Compounds; Natural Compounds Chemical Class; Cytokine signaling. Its EINECS number is 207-540-8. This chemical's molecular formula is C15H22O9and molecular weight is 346.33. What's more, its IUPAC name is (2S,3R,4S,5S,6R)-2-[-(1S,4aR,5S,7aS-5-hydroxy-7-(hydroxymethyl-1,4a,5,7a-tetrahydrocyclopenta-[c]-pyran-1-yl]-oxy]-6-(hydroxymethyl)-oxane-3,4,5-triol. It should be sealed and stored in a ventilated and dry place. Moreover, it should be protected from oxides. Aucubin is an iridoid glycoside. It is found in plants used in traditional Chinese and folk medicine. It was found to protect against liver damage induced by carbon tetrachloride or alpha-amanitin in mice and rats when 80 mg/kg was dosed intraperitoneally. This chemical is used in biochemical research.
