IUPAC 名称
(2R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-[(1R,12R)-5,7,11,19-tetraoxapentacyclo[10.8.0.0²,¹⁰.0⁴,⁸.0¹³,¹⁸]icosa-2,4(8),9,13(18),14,16-hexaen-16-yloxy]oxane-3,4,5-triol
描述
(-)-maackiain-3-o-glucoside, also known as trifolrhizin, is a member of the class of compounds known as pterocarpans. Pterocarpans are benzo-pyrano-furano-benzene compounds, containing the 6H-[1]benzofuro[3,2-c]chromene skeleton. They are derivatives of isoflavonoids (-)-maackiain-3-o-glucoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). (-)-maackiain-3-o-glucoside can be found in a number of food items such as pepper (c. pubescens), loquat, nopal, and kiwi, which makes (-)-maackiain-3-o-glucoside a potential biomarker for the consumption of these food products.
