A Scientific Deep Dive into Fructus Mori's Health Benefits
The unassuming mulberry, a fruit often overshadowed by its flashier counterparts, is quietly emerging as a powerhouse of health benefits, backed by cutting-edge science.
Imagine a fruit so potent it can enhance your memory, protect your liver, and combat oxidative stress, all while being a delicious and natural food. This isn't a futuristic superfood; it's the mulberry, known in scientific circles as Fructus Mori.
For centuries, it has been a staple in traditional Oriental medicine, revered for its ability to "tonify kidneys and consolidate essence," believed to make "hair black and eyes bright" 1 4 . Today, modern research is uncovering the remarkable phytonutrients behind these ancient claims, revealing a complex profile of polysaccharides, flavonoids, and alkaloids that offer a plethora of health benefits 1 5 .
Mulberries come in several varieties including white, red, and black, each with slightly different nutritional profiles and health benefits.
Cognitive Health
Antioxidant
Liver Protection
The health benefits of Fructus Mori are not due to a single "magic bullet" but rather a synergistic combination of numerous active compounds. A comprehensive review of its phytonutrients reveals a rich and diverse chemical landscape 1 .
This is the most abundant group of phytonutrients in mulberry, with a wide range of reported biological activities 1 .
These compounds are known for their potent antioxidant effects, helping to neutralize harmful free radicals in the body 1 5 .
Another class of antioxidants that contribute to the fruit's anti-inflammatory and anti-aging properties 1 .
Recent research has particularly spotlighted Mori Fructus polysaccharides (MFPs). These are not just simple sugars; they are complex pectin-type structures that have shown incredible versatility in promoting health.
Prebiotic Effects
Liver Protection
From acting as prebiotics for gut flora to protecting liver cells from damage caused by a high-fat diet 2 3 9 .
While many studies focus on metabolic health, one particularly fascinating area of research explores the impact of mulberry on the brain. A groundbreaking study published in the British Journal of Nutrition set out to investigate the memory-enhancing effect of Mori Fructus, with a specific focus on how it influences Nerve Growth Factor (NGF) 4 6 .
Nerve Growth Factor (NGF) is a critical protein for the survival, development, and function of cholinergic neurons in the brain, which are essential for learning and memory processes 4 .
The researchers designed a meticulous experiment using mice to unravel the connection between mulberry extract and brain function 4 :
Dried mulberry fruit was extracted with 70% ethanol, filtered, evaporated, and freeze-dried into a powder (abbreviated as ME) 4 .
Mice were randomly divided into groups and orally administered different doses of ME (20, 100, and 500 mg per kg of body weight) daily for seven days. A control group received no extract 4 .
The findings from this experiment were striking and provided strong evidence for mulberry's brain-boosting potential.
| Investigation Area | Key Finding |
|---|---|
| NGF Induction | ME dose-dependently promoted NGF release in the hippocampus 4 . |
| Synapse Formation | ME significantly increased both pre- and post-synapse markers 4 . |
| Neurogenesis | Increased neuronal cell differentiation, neurite outgrowth, and cell proliferation were observed 4 . |
| Behavioral Tests | ME significantly increased latency time in the passive avoidance task and improved recognition of novel objects 4 6 . |
Conclusion: The memory-enhancing effect was likely due to the up-regulation of NGF by the mulberry extract. The flavonoids and other phenolic compounds in ME are small enough to cross the blood-brain barrier, where they can trigger a cascade of events that ultimately lead to increased NGF production, improved brain plasticity, and better cognitive function 4 .

Synapse Formation
To achieve these fascinating results, scientists rely on a suite of specialized reagents and methods. The table below outlines some of the essential tools used in the field of Fructus Mori research, particularly in studies focusing on bioactivity.
| Reagent / Tool | Function in Research | Example from the Studies |
|---|---|---|
| DPPH & ABTS | Chemicals used to measure the antioxidant activity of extracts by assessing their ability to scavenge free radicals. | Used to show that mulberry polysaccharides have good free radical scavenging ability 3 7 . |
| α-amylase & α-glucosidase | Enzymes targeted in diabetes research. Inhibiting them can slow carbohydrate digestion and lower blood sugar. | Used in assays to demonstrate the hypoglycemic potential of mulberry polysaccharides 7 . |
| Cell Lines (HepG2, RAW264.7) | In vitro models for studying liver function and immune/inflammatory responses, respectively. | HepG2 cells were used to show hepatoprotective effects 9 ; RAW264.7 cells were used to study anti-inflammatory activity 5 9 . |
| ELISA Kits | Tools to precisely measure specific proteins (like NGF or cytokines) in a sample. | A chemokine NGF sandwich ELISA kit was used to measure NGF levels in the mouse brain 4 . |
| Monosaccharide Standards | Reference compounds used to analyze the sugar composition of polysaccharides. | Used with HPLC to determine that a key mulberry polysaccharide (PFM-3) is composed of Glucose, Mannose, and Fucose 7 9 . |
The compelling scientific evidence is being translated into real-world products. As a "dual-purpose resource for medicine and food," Fructus Mori has already found its way into various applications, including vinegar, wine, yogurt, drinks, jelly, and sweetmeats 1 .
| Extraction Method | Impact on Polysaccharides |
|---|---|
| Hot Water | Yields polysaccharides with stronger antioxidant and α-amylase inhibitory activities . |
| Ultrasonic | Can degrade molecular weight, which may reduce some activities . |
| Temperature Variation | Lower temperatures (30°C) can preserve antioxidant activity, while higher temperatures (90°C) can increase bile acid-binding capacity 7 . |
Future research is poised to dive even deeper. Scientists are now working to:
As you enjoy the sweet taste of a mulberry, remember that you are partaking in a fruit that nourishes both the body and the mind, a true testament to the wisdom of nature and the power of science.
