【Main ingredients】: Black rice is rich in nutrients such as protein, carbohydrates, B vitamins, vitamin E, calcium, phosphorus, potassium, magnesium, iron, and zinc. It contains higher levels of inorganic salts like manganese, zinc, and copper—1 to 3 times more than white rice. Additionally, black rice is unique in its content of vitamin C, chlorophyll, anthocyanins, carotene, and cardiac glycosides, which are lacking in white rice. As a result, black rice is more nutritious than ordinary white rice. ‌

Summary of Modern Pharmacological Research on Black Rice Extract

Black rice (Oryza sativa L. indica), often termed “forbidden rice,” is gaining significant scientific attention due to its dense concentration of bioactive compounds, primarily anthocyanins (like cyanidin-3-O-glucoside), along with flavonoids, phenolic acids, and vitamin E. Modern pharmacological research highlights its potential in several therapeutic areas.

1. Antioxidant and Anti-inflammatory Activity
   The most well-established property is its potent antioxidant capacity. Black rice extract (BRE) effectively scavenges free radicals (e.g., DPPH, ABTS radicals) and reduces oxidative stress markers in vitroand in animal models. This activity is directly linked to its anthocyanin content. Concurrently, BRE demonstrates anti-inflammatory effects by inhibiting the production of pro-inflammatory mediators like nitric oxide (NO), prostaglandin E2 (PGE2), and cytokines (TNF-α, IL-6), often through the suppression of the NF-κB signaling pathway.
2. Cardioprotective and Anti-atherosclerotic Effects
   Research indicates BRE can improve lipid profiles by reducing serum triglycerides, LDL-cholesterol, and total cholesterol while increasing HDL-cholesterol in diet-induced hyperlipidemic animals. It protects vascular endothelial function, reduces atherosclerotic plaque formation, and exhibits anti-hypertensive potential, contributing to overall cardiovascular health.
3. Anti-diabetic and Anti-obesity Effects
   BRE shows promise in managing metabolic disorders. It can inhibit digestive enzymes (α-amylase, α-glucosidase), potentially slowing carbohydrate absorption. Studies in diabetic models report improved insulin sensitivity, reduced blood glucose levels, and protection of pancreatic β-cells. Its anti-obesity effects are linked to the inhibition of adipogenesis (fat cell formation) and reduction of lipid accumulation in tissues.
4. Hepatoprotective and Neuroprotective Effects
   BRE protects the liver from damage induced by toxins, alcohol, or high-fat diets by mitigating oxidative stress and inflammation, thereby reducing serum markers of liver injury (ALT, AST). Emerging neuropharmacological studies suggest BRE can cross the blood-brain barrier, attenuate oxidative stress in neuronal cells, inhibit acetylcholinesterase, and reduce neuroinflammation, showing potential in models of cognitive impairment and Alzheimer’s disease.
5. Anti-cancer Potential
   In vitrostudies report that BRE and its anthocyanins exhibit anti-proliferative and pro-apoptotic effects against various cancer cell lines, including breast, colon, gastric, and leukemia cells. Proposed mechanisms include cell cycle arrest, induction of apoptosis via mitochondrial pathways, and inhibition of cancer cell metastasis and angiogenesis. However, robust in vivoclinical evidence is still needed.
6. Skin Protection
   Topical application or oral intake of BRE has been shown in studies to protect skin from ultraviolet B (UVB)-induced damage, wrinkle formation, and hyperpigmentation by scavenging free radicals and inhibiting melanin synthesis.

Conclusion
Modern pharmacological research substantiates the broad health potential of black rice extract, primarily attributed to its anthocyanins. Its activities span antioxidant, anti-inflammatory, cardiometabolic, hepatoprotective, and neuroprotective effects. Most evidence is derived from in vitro and animal studies; therefore, further well-designed human clinical trials are essential to validate these therapeutic benefits and establish effective dosing for human health applications.
