Mogroside V, a cucurbitane-type saponin, is not only the major bioactive constituent of traditional Chinese medicine Siraitiae Fructus, but also a widely used sweetener. To clarify its biotransformation process and identify its effective forms in vivo, we studied its metabolism in a human intestinal bacteria incubation system, a rat hepatic 9000g supernatant (S9) incubation system, and rats. Meanwhile, the distribution of Mogroside V and its metabolites was also reported firstly. Seventy-seven new metabolites, including 52 oxidation products formed by mono- to tetra- hydroxylation/dehydrogenation, were identified with the aid of HPLC in tandem with ESI ion trap (IT) TOF multistage mass spectrometry (HPLC-ESI-IT-TOF-MS(n)). Specifically, 14 metabolites were identified in human intestinal bacteria incubation system, 4 in hepatic S9 incubation system, 58 in faeces, 29 in urine, 14 in plasma, 34 in heart, 33 in liver, 39 in spleen, 39 in lungs, 42 in kidneys, 45 in stomach, and 51 in small intestine. The metabolic pathways of Mogroside V were proposed and the identified metabolic reactions were deglycosylation, hydroxylation, dehydrogenation, isomerization, glucosylation, and methylation. Mogroside V and its metabolites were distributed unevenly in the organs of treated rats. Seven bioactive metabolites of Mogroside V were identified, among which mogroside IIE was abundant in heart, liver, spleen and lung, suggesting that it may contribute to the bioactivities of Mogroside V. Mogroside V was mainly excreted in urine, whereas its metabolites were mainly excreted in faeces. To our knowledge, this is the first report that a plant constituent can be biotransformed into more than 65 metabolites in vivo. These findings will improve understanding of the in vivo metabolism, distribution, and effective forms of Mogroside V and congeneric molecules.

Analysis of Mogroside V in Siraitia grosvenorii with micelle-mediated cloud-point extraction.[Pubmed:23349010]

Phytochem Anal. 2013 Jul-Aug;24(4):381-5.

INTRODUCTION: Mogroside V is the main effective ingredient of Siraitia grosvenorii used as a natural sweet food as well as a traditional Chinese medicine. The sample pre-treatment prior to chromatographic analysis requires large amounts of toxic organic solvents and is time consuming. OBJECTIVE: To develop an effective and simple method for extracting and determining Mogroside V of Siraitia grosvenorii. METHODS: Mogroside V was extracted and preconcentrated by micelle-mediated cloud-point extraction with nonionic surfactant isotridecyl poly (ethylene glycol) ether (Genapol(R) X-080). The obtained solutions containing Mogroside V were analysed by high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection. The chromatographic separation was performed on a C18 -column using gradient elution with acetonitrile and water at 203 nm. RESULTS: The cloud-point extraction yield was 80.7% while the pre-concentration factor was about 10.8. The limit of detection was 0.75 microg/mL and the limit of quantification was 2 microg/mL. The relative standard deviations for intra- and interday precisions of Mogroside V were less than 8.68% and 5.78%, respectively, and the recoveries were between 85.1% and 103.6%. CONCLUSION: The HPLC-UV method based on micelle-mediated cloud-point extraction for determination Mogroside V in Siraitia grosvenorii was environmentally friendly, simple and sensitive.

Protective effects and mechanisms of mogroside V on LPS-induced acute lung injury in mice.[Pubmed:24621273]

Pharm Biol. 2014 Jun;52(6):729-34.

CONTEXT: Mogroside V, a compound isolated from Momordica grosvenori Swingle, which belongs to the Cucurbitaceae, is a traditional Chinese medicine reported to have anti-inflammatory potential in murine macrophages and a murine ear edema model. OBJECTIVE: To investigate the effects and mechanisms of action of this compound in a model of acute lung injury (ALI) induced by lipopolysaccharides (LPS). MATERIALS AND METHODS: Female BALB/c mice were treated with commercial Mogroside V (2.5, 5 and 10 mg/kg) for 1 h prior to intranasal injection of LPS (10 mug in 50 mul). After 12 h, airway inflammation in the ALI model was determined by the wet/dry weight (W/D) ratio, myeloperoxidase (MPO) activity of lung tissue, leukocyte recruitment and cytokine levels in the bronchoalveolar lavage fluid (BALF). Additionally, lung tissue was examined by histology and western blotting to investigate the changes in pathology and the signalling in the presence and absence of Mogroside V. RESULTS: Mogroside V at 5 and 10 mg/kg inhibited airway inflammation induced by LPS as measured by the decrease in the histological changes (44 and 67.3% reduction in lung injury score, respectively), a 28.9 and 55.3% reduction in lung MPO activity, and inflammatory cell counts, interleukin-1beta (IL-1beta, 382 and 280 pg/ml, respectively), IL-6 (378 and 232 pg/ml, respectively) and tumor necrosis factor-alpha (TNF-alpha, 12.5 and 7.8 ng/ml, respectively) levels in the BALF. Additionally, Mogroside V treatment reduced the activation of cyclooxygenase 2 (COX-2), inducible NO synthase (iNOS), and the nuclear factor (NF)-kappaB. DISCUSSIONS AND CONCLUSIONS: Together, these data suggest that Mogroside V has the potential to protect against LPS-induced airway inflammation in a model of ALI.

Mogroside V, a triterpenoid glycoside isolated from the extracts of Luo Han Guo, is a nonsugar sweetener. Mogroside V is nearly 300 times sweeter than sucrose. Mogrosides exhibit antioxidant, antidiabetic and anticancer activities. Mogrosides are sweeter than sucrose.
