Dioscin
IUPAC 名称
2-[(2-{[4,5-dihydroxy-2-(hydroxymethyl)-6-{5,7',9',13'-tetramethyl-5'-oxaspiro[oxane-2,6'-pentacyclo[10.8.0.0²,⁹.0⁴,⁸.0¹³,¹⁸]icosan]-18'-eneoxy}oxan-3-yl]oxy}-4,5-dihydroxy-6-methyloxan-3-yl)oxy]-6-methyloxane-3,4,5-triol
描述
Dioscin is a member of the class of compounds known as steroidal saponins. Steroidal saponins are saponins in which the aglycone moiety is a steroid. The steroidal aglycone is usually a spirostane, furostane, spirosolane, solanidane, or curcubitacin derivative. Dioscin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Dioscin can be found in fenugreek and yam, which makes dioscin a potential biomarker for the consumption of these food products.
