Guava Leaf Extract

Guava leaf extract is a concentrated natural active ingredient extracted from the leaves of the guava (Psidium guajava), a plant in the Myrtaceae family. It is widely used in the food, health product, and pharmaceutical industries. Its main active ingredients include:

• Polyphenols (such as ellagic acid and tannins)
• Flavones (such as quercetin, kaempferol, guavaside, and eugenol)
• Triterpenoids (such as ursolic acid and crataegolic acid)
• Volatile oils (containing eugenol, cis-3-hexen-1-ol, etc.)

• Lowering Blood Sugar: Flavonoids and triterpenoids in guava leaf extract can improve insulin sensitivity, inhibit α-glucosidase activity, and slow down carbohydrate digestion and absorption, thereby helping to regulate blood sugar levels and providing some adjunctive treatment for diabetic patients.
• Anti-inflammatory and Antibacterial: Quercetin and tannins in the extract have anti-inflammatory and antibacterial activities, inhibiting the growth of bacteria such as Escherichia coli, Staphylococcus aureus, and Shigella dysenteriae, and reducing inflammatory responses, providing some relief for skin inflammation, oral inflammation, and intestinal infections.
• Antioxidant: Rich in vitamin C, flavonoids, polyphenols, and other antioxidants, it can scavenge free radicals, reduce oxidative stress damage to cells, and help delay aging and prevent chronic diseases.
• Antispasmodic and Antidiarrheal: Quercetin and other components can inhibit intestinal smooth muscle contraction, reduce intestinal peristalsis, relieve diarrhea and abdominal pain symptoms, and have a certain regulatory effect on intestinal dysfunction.
• Cardiovascular protection: Some studies suggest that guava leaf extract may help lower blood pressure, regulate blood lipids, and reduce the risk of cardiovascular disease, but the specific mechanisms require further investigation.

Pharmaceutical and Healthcare Fields

• Blood Sugar Lowering and Diabetes Management: Inhibits protein tyrosine phosphatase 1b (PTP1B), improves insulin sensitivity, slows carbohydrate absorption, helps regulate blood sugar levels, and assists in the treatment of type 2 diabetes. 
• Anti-inflammatory and Immune Modulation: Inhibits phosphodiesterase 4 (PDE4), reduces inflammatory responses, and has a relieving effect on inflammatory diseases such as arthritis, gastritis, and enteritis.
• Antibacterial and Antiviral: Inhibits bacteria such as Escherichia coli, Shigella, and Staphylococcus aureus, as well as rotavirus and norovirus-like viruses, and can be used to treat infectious diseases.
• Cardiovascular Protection: Synergistically activates the SIRT1/NRF2 signaling pathway, reduces oxidative stress and inflammation, prevents high-fructose-induced cardiac damage, regulates blood lipids, and reduces the risk of atherosclerosis.

Food and Health Products Fields

• Functional Food Additives: As a natural antioxidant, added to beverages, pastries, dairy products, etc., to extend shelf life and enhance nutritional value.
• Health Teas and Beverages: Made into guava leaf tea or extract drinks, it helps regulate blood sugar and promotes digestion, suitable for diabetics or health-conscious individuals.

Agriculture and Aquaculture

• Aquatic Disease Control: Used to prevent aquatic diseases such as white spot syndrome virus in shrimp, reducing the risk of virus transmission and decreasing antibiotic use.
• Plant Protection: As a natural antibacterial agent, used to control crop pests and diseases, reducing reliance on chemical pesticides.
