| Description | Torvoside B belongs to the class of organic compounds known as steroidal saponins. These are saponins in which the aglycone moiety is a steroid. The steroidal aglycone is usually a spirostane, furostane, spirosolane, solanidane, or curcubitacin derivative. Torvoside B is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, torvoside b has been detected, but not quantified in, fruits. 2-{4-[19-({3,5-dihydroxy-6-methyl-4-[(3,4,5-trihydroxyoxan-2-yl)oxy]oxan-2-yl}oxy)-16-hydroxy-6-methoxy-7,9,13-trimethyl-5-oxapentacyclo[10.8.0.0²,⁹.0⁴,⁸.0¹³,¹⁸]icosan-6-yl]-2-methylbutoxy}-6-(hydroxymethyl)oxane-3,4,5-triol is found in Solanum torvum. This could make torvoside b a potential biomarker for the consumption of these foods. |
