Protoeruboside B
IUPAC 名称
2-({2-[(6-{[6,19-dihydroxy-7,9,13-trimethyl-6-(3-methyl-4-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}butyl)-5-oxapentacyclo[10.8.0.0²,⁹.0⁴,⁸.0¹³,¹⁸]icosan-16-yl]oxy}-4,5-dihydroxy-2-(hydroxymethyl)oxan-3-yl)oxy]-5-hydroxy-6-(hydroxymethyl)-3-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}oxan-4-yl}oxy)-6-(hydroxymethyl)oxane-3,4,5-triol
描述
Protoisoeruboside b 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. Protoisoeruboside b is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Protoisoeruboside b can be found in garlic, onion-family vegetables, and soft-necked garlic, which makes protoisoeruboside b a potential biomarker for the consumption of these food products.
