描述
Officinalisnin i 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. Officinalisnin i is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Officinalisnin i can be found in asparagus, which makes officinalisnin i a potential biomarker for the consumption of this food product.
