Mogroside
A mogroside is a triterpene glycoside of cucurbitane derivatives found in certain plants, such as the fruit of the gourd vine Siraitia grosvenorii (known as monkfruit or luohan guo).[1][2] Mogrosides are extracted from S. grosvenorii and used in the manufacture of sugar substitutes.[1][2]

The total content of mogrosides in Siraitia grosvenorii fruit is 3.8% with Mogroside V having the highest content (0.8% to 1.3% w/w).[3]
Biosynthesis
One analysis of 200 candidate genes of Siraitia grosvenorii revealed five enzyme families involved in the synthesis of mogroside V: squalene epoxidases, triterpenoid synthases, epoxide hydrolases, cytochrome P450s, and UDP-glucosyltransferases.[1] The metabolic pathway for mogroside biosynthesis involves an initial stage of fruit development when squalene is metabolized to di-glucosylated, tetra-hydroxycucurbitadienols, then during fruit maturation, branched glucosyl groups are added and catalyzed, leading to the sweet M4, M5, and M6 mogrosides.[1]
Stability
Mogroside V appears to be heat stable in the range of 100 to 150 degrees Celsius for 4 hours and up to 8 hours in boiling water. It is stable at a pH of between 3 and 12 when stored from 2 to 8 degrees Celsius.[4]
Uses
Some mogrosides are used in traditional Chinese medicine[2] and some are extracted for manufacturing as sweeteners.[1] Mogroside V extract from S. grosvenorii fruit is 250 times sweeter than sucrose,[1] sold commercially in Norbu (sweetener).
