Introduction/Overview
Fructo oligosaccharides DP10 (FOS DP10 or GF9, CAS number 118150-64-4) is a type of oligofructose formed by the connection of fructose units through β - (2 → 1) glycosidic bonds, and belongs to the natural product of oligosaccharides. As a typical prebiotic, cane sugar has received widespread attention in the fields of gut microbiota regulation, immune regulation, and prevention and treatment of metabolic diseases in recent years due to its unique structure and biological activity. Its molecular weight is approximately 1639.4 Da, and it has good water solubility and low fat solubility (LogP-5.4185), making it exhibit excellent bioavailability and safety in the intestinal environment.
As an important regulatory factor for human health, the balance of gut microbiota directly affects the occurrence and development of various chronic diseases. Sugar from sugarcane fruit selectively promotes the growth of beneficial bacteria such as bifidobacteria and lactobacilli, regulates the intestinal microbiota environment, and thus affects the host's immune response and metabolic function. In recent years, relevant studies have revealed that cane sugar can participate in regulating intestinal barrier function, inflammatory response, and metabolic homeostasis through various molecular targets such as AMPK, TLR4, TLR2, NOD2, NFKB1, IL10, MYD88, DEFB1, MUC2, and PPAR γ, demonstrating its potential value in the prevention and treatment of intestinal related diseases.
This article will provide a systematic review of the chemical structure and physicochemical properties, plant sources, and extraction methods of cane fruit sugar, with a focus on its pharmacological activity and mechanism of action. Combined with drug evaluation and pharmacokinetic characteristics, it will explore its clinical application prospects and future research directions, aiming to provide theoretical basis and reference for the development and utilization of this natural product.
Chemical structure and physicochemical properties
Sucrose belongs to the fructooligosaccharides (FOS) family, consisting mainly of 9 to 10 fructose residues linearly connected by β - (2 → 1) glycosidic bonds, typically ending with a glucose residue. Its chemical formula is C60H-102O51, with a molecular weight of approximately 1639.4250 Da. Structurally, the high degree of polymerization of cane fruit decaose endows it with a large molecular weight and complex three-dimensional conformation, which affects its stability and functional performance in vivo.
In terms of physical and chemical properties, cane fruit ten sugar exhibits strong hydrophilicity, with a TPSA (topological polar surface area) of up to 822.73 Å ², indicating the presence of a large number of polar groups on its molecular surface, which is conducive to water solubility and interaction with biomolecules. Its LogP value is -5.4185, indicating extremely low lipid solubility, which limits its passive diffusion through lipid membranes, consistent with its main functional localization in the intestinal lumen. The water solubility is 28.8734 mg/mL, suitable for preparation as a water-soluble formulation. The blood-brain barrier has extremely low permeability, indicating that it is difficult to enter the central nervous system and reduces the risk of central toxicity.
In terms of safety, cane fruit ten sugar did not show hERG channel inhibitory activity, indicating a low risk of cardiac toxicity. The Ames test result is 0.9, indicating that it has no significant mutagenicity and meets the good safety characteristics of natural products.
Plant sources and extraction methods
Sucrose is mainly found in various plants, especially in the roots, stems, and fruits of sugarcane (Saccharum officinarum), onion (Allium cepa), chicory (Cichorium intybus), and other plants. Sugarcane juice is rich in a variety of fructooligosaccharides, which is the main source of raw materials for industrial production of cane fructose.
Traditional extraction methods include water extraction, alcohol precipitation, ion exchange, and membrane separation techniques. The specific process is usually as follows: first, plant raw materials are extracted by hot water or warm water, and pectin is dissolved out using the advantage of water solubility; Subsequently, alcohol (such as ethanol) precipitation is used to remove high molecular impurities and proteins; Removing charged impurities and pigments through ion exchange resin; Finally, ultrafiltration membrane technology was used to separate fructooligosaccharides with different degrees of polymerization, obtaining high-purity cane fruit decasaccharides.
In recent years, the introduction of ultrasound assisted extraction and enzymatic hydrolysis has significantly improved extraction efficiency and purity. Enzymatic hydrolysis utilizes specific fructosyltransferases to catalyze the synthesis or modification of oligofructose, which can accurately control the degree of polymerization and obtain structurally uniform cane sugar products.
Pharmacological activity research
As a prebiotic, the most significant pharmacological activity of cane fruit sugar is reflected in the regulation of gut microbiota and improvement of immune function. Numerous in vitro and in vivo studies have shown that cane sugar can selectively promote the proliferation of beneficial bacteria such as bifidobacteria and lactobacilli, inhibit the growth of pathogenic bacteria, optimize the intestinal microbiota structure, and enhance intestinal barrier function.
In animal models, the intake of cane sugar significantly reduces intestinal inflammation indicators, alleviates intestinal mucosal damage, and improves intestinal permeability. It promotes energy metabolism and repair of intestinal epithelial cells by regulating the levels of metabolites such as short chain fatty acids (SCFAs) in the gut microbiota. Cane fructose also has the effects of regulating lipid metabolism, antioxidation and anti-inflammatory, which is helpful to prevent obesity, diabetes and metabolic syndrome.
Preliminary clinical studies have confirmed that cane fruit sugar, as a dietary supplement, can improve symptoms of intestinal dysfunction such as constipation and diarrhea, enhance immune tolerance, and reduce the risk of infection. Its good safety and tolerability make it an important ingredient in functional foods and intestinal health products.
Mechanism of action and molecular targets
The biological effects of cane sugar are mainly achieved by regulating the gut microbiota and its metabolites, thereby affecting host immunity and metabolic signaling pathways. Its key molecular targets include:
-
AMPK(5' AMP-activated protein kinase)Sugar from sugarcane fruit promotes the production of short chain fatty acids, activates the AMPK signaling pathway in intestinal epithelial cells, regulates energy metabolism, promotes cell repair and anti-inflammatory response.
-
TLR4 and TLR2 (Toll like receptors 4 and 2)Sugar from sugarcane fruit regulates the composition of intestinal microbiota, reduces the activation of TLR4/2 by pathogen associated molecular patterns (PAMPs), alleviates inflammatory responses, and maintains intestinal immune homeostasis.

Evaluation of drug properties and pharmacokinetics
As a natural oligosaccharide, the evaluation of the medicinal properties of cane fruit ten sugar shows multiple advantages. Firstly, its large molecular weight and extremely high polarity (TPSA 822.73 Å ²) result in its oral action being mainly limited to the intestine, avoiding systemic exposure and potential toxic side effects. Low fat solubility (LogP-5.4185) and low blood-brain barrier permeability reduce the risk of central nervous system toxicity.
In terms of safety, cane fruit ten sugar has no hERG channel inhibition and a negative Ames test, indicating extremely low risk of cardiac toxicity and mutagenicity, making it suitable for long-term dietary supplementation.
Pharmacokinetic studies have shown that cane fruit sugar is not broken down by human digestive enzymes after oral administration, but is mainly fermented and utilized by gut microbiota, producing metabolic products such as short chain fatty acids and exerting physiological functions. Its bioavailability is mainly reflected in the intestinal lumen, with minimal systemic absorption, consistent with the characteristics of prebiotics.
In terms of formulation development, cane fruit sugar has good water solubility and is suitable for preparation as oral liquids, powders, and functional food additives. It has high stability and is easy to industrialize production and storage.
