Brief Introduction Synonyms--- Arhat fruit, Monk’s fruit, Luo Han Guo (Chinese:罗汉果), Longevity Fruit Mogroside V (Esgoside) Chemical Name: mogrol-3-O-(beta-D-glucopyranosyl (1-6)-beta-D-glucopyranoside)-24-O- ((beta-D-glucopyranosyl (1-2))-(beta-D-glucopyranosyl(1-6))-beta-D-glucopyranoside) Molecular Formula: C60H102O29 Mol. Wt.: 1287.43 Molecular Structure: Siraitia grosvenorii (Momordica grosvenori) is an herbaceous perennial vine and best known for its fruit, the luo han guo (Chinese: 罗汉果). The vine grows to 3 to 5 m long, climbing over other plants by means of tendrils which twine round anything they touch. The narrow, heart-shaped leaves are 10–20 cm long. The fruit is globose, 5–7 cm in diameter, and contains a sweet, fleshy, edible pulp and numerous seeds. The fruit is one of several that have been called longevity fruit. Luo Han Guo is native to southern China, primarily grown in the southwestern China (mostly in the mountains of Guilin, Guangxi province).These mountains lend the plants shadows and often are surrounded by mists (protect the plant from the sun), which together with the warm climate in this southern province of China provide the special conditions for Luo Han Guo growing. The fruit extract is nearly 300 times sweeter than sugar and has been used as a natural sweetener in China for nearly a millennium due to its flavor and lack of food energy, only 2.3 kcal/g (9.6 kJ/g). It has also been used in traditional Chinese medicine.
