Monk fruit is the fruit of the plant *Siraitia grosvenorii*, a perennial vine native to southern China. It is best known for its intensely sweet mogrosides, which are used to produce a calorie-free sweetener. The fruit has also been used in traditional Chinese medicine and culinary applications.

Description

Monk fruit refers to the fruit of *Siraitia grosvenorii*, a vine in the gourd family. The plant is native to humid, subtropical regions of southern China and is cultivated for its fruit extract.

Uses

The fruit is used to make a sweetener that is much sweeter than sugar but contains little to no calories. It is also used in traditional Chinese medicine and in some foods and beverages.

Chemical composition

Monk fruit’s sweetness comes mainly from mogrosides, a group of natural compounds concentrated in the fruit. These compounds are responsible for the sweet taste used in commercial extracts.

Distribution and cultivation

The plant is found mainly in southern Chinese provinces such as Guangxi, Hunan, Jiangxi, Guangdong, and Guizhou. It is cultivated because the fresh fruit is not typically consumed widely on its own.
