Introduction/Overview
With the global prevalence of metabolic diseases, especially the high incidence of diabetes, the development of safe and effective anti diabetes natural products has become an important direction of drug research and development. Siraitia grosvenorii, as the representative of traditional Chinese medicine and natural sweeteners, its main active ingredients Arhat fruit glycosides have attracted much attention due to their low calorie, high sweetness and multiple biological activities. 11 deoxymogroside IIIE (11 deoxymogroside IIIE) is an important triterpene glycoside in Arhat grosvenorii, which has shown significant pharmacological potential in the field of anti diabetes in recent years. In this paper, the chemical structure, extraction method, pharmacological activity, mechanism of action, and evaluation of drug performance of 11 deoxygenated Arhat fruit glycoside IIIE are systematically reviewed, in order to provide scientific basis for its clinical transformation and new drug development.
Chemical structure and physicochemical properties
11 deoxygenated Arhat fruit glycoside IIIE is a high molecular weight triterpene sweet glycoside with a molecular weight of 947.1660, a complex molecular formula, and a steroid skeleton connected by multiple glycosides. Its LogP value is 2.5042, indicating moderate hydrophobicity that facilitates cell membrane penetration but is not prone to excessive accumulation. The TPSA (topological polar surface area) is 298.14, indicating its high polarity and number of hydrogen bond donors/acceptors, which may affect its oral absorption and bioavailability. Low water solubility (0.0952) suggests limited solubility in aqueous media and may require appropriate formulation techniques to improve its bioavailability. Low blood-brain barrier penetration ability reduces the risk of central nervous system side effects. The negative result of hERG inhibition experiment indicates a low risk of cardiac toxicity. The Ames test was 0.0, indicating no significant genotoxicity.
The chemical structure core of 11 deoxygenated Arhat fruit glycoside IIIE is a pentacyclic triterpene skeleton, and the characteristics of 11 anoxic groups make it distinct from other Arhat fruit glycosides. Its polysaccharide glycosylation modification endows it with strong water solubility and biological activity, and the type and connection mode of sugar chains have a significant impact on its pharmacological effects.
Plant sources and extraction methods
11 deoxygenated Arhat IIIE is mainly obtained from siraitia grosvenorii fruit. Momordica grosvenorii is a cucurbitaceae plant native to southern China, and its fruit contains rich sweet glycosides. Traditional extraction processes often use water extraction combined with alcohol precipitation. In recent years, the application of ultrasound assisted extraction, microwave-assisted extraction, and membrane separation technology has significantly improved extraction efficiency and purity.
The specific extraction process generally includes: fresh or dried siraitia grosvenorii fruit is crushed, and then extracted with hot water or 70% ethanol. After the extraction solution is filtered and concentrated, the impurities are separated with organic solvents, and then purified by column chromatography (such as silica gel column, reverse phase C18 column). Finally, 11 deoxygenated Arhat glycoside IIIE is identified and separated by high performance liquid chromatography (HPLC). In recent years, the introduction of supercritical CO2 extraction and membrane separation technology has further optimized the extraction process, ensuring the stability and biological activity of active ingredients.

SGLT2 inhibition
Sodium glucose cotransporter 2 (SGLT2) is a key target for renal glucose reabsorption. 11 deoxygenated Arhat fruit glycoside IIIE has a certain inhibitory effect on SGLT2, promotes urine glucose excretion, and reduces blood sugar level.
GCK and PPARG regulation
Glucokinase (GCK) is the key enzyme of glucose metabolism. 11 deoxygenated Arhat glycoside IIIE can enhance its activity and promote glucose metabolism. Peroxisome proliferator activated receptor γ (PPARG) regulates lipid metabolism and insulin sensitivity, and 11 deoxygenated Arhat fruit glycoside IIIE improves lipid metabolism abnormalities by regulating PPARG expression.
