What are the two specific triterpenoids isolated that reduced TC in test subjects?

Answer

Lupeol acetate and $eta$-amyrin acetate

The systemic cholesterol-lowering effect observed in animal models, particularly in hamsters consuming high-cholesterol diets, is hypothesized to be driven by specific compounds classified as triterpenoids found within the miracle fruit seeds. Scientific investigation successfully isolated and identified two specific triterpenoids that were confirmed to be responsible for this activity. These two particular compounds are named lupeol acetate and $eta$-amyrin acetate. When these isolated components were added to the diet of test subjects, they successfully demonstrated the capacity to reduce Total Cholesterol (TC) levels significantly, registering a reduction within the measurable range of 15% to 20%.
