QUERCETIN DIHYDRATE EXTRACT 95% (SOPHORA JAPONICA)(WHOLE FLOWER BUD)

Quercetin dihydrate 95% extract, derived from Sophora japonica (Japanese Pagoda Tree) whole flower bud, is a highly concentrated form of this ubiquitous plant flavonoid. Sophora japonica has been a traditional source for quercetin and rutin in Eastern medicine for centuries, prized for its purported health-supporting properties. This specific extract is standardized to 95% quercetin dihydrate, ensuring a potent and consistent profile of the active compound. Quercetin is a naturally occurring polyphenol found in various fruits, vegetables, and grains, known for its vibrant yellow pigment and significant biological activity. The dihydrate form refers to its stable crystalline structure, which influences its solubility and bioavailability. Its extensive presence in the plant kingdom, including in apples, onions, berries, and tea, underscores its evolutionary importance and widespread dietary intake, making it a well-researched ingredient in the nutraceutical industry. This high-purity extract provides a reliable and concentrated source for targeted supplementation.

The primary health benefits of quercetin are largely attributed to its potent antioxidant and anti-inflammatory properties. As a powerful free radical scavenger, quercetin effectively neutralizes reactive oxygen species, thereby mitigating oxidative stress, a key contributor to cellular damage and various chronic conditions. Research indicates that quercetin modulates cellular signaling pathways involved in inflammation, suchating effects on cyclooxygenase (COX) and lipoxygenase (LOX) enzymes, as well as inhibiting histamine release from mast cells. This dual action contributes to its potential in supporting immune function and managing inflammatory responses. Furthermore, quercetin has been shown to support cardiovascular health by improving endothelial function, reducing blood pressure in hypertensive individuals, and inhibiting LDL oxidation, as demonstrated in various in vitro and in vivo studies. Its comprehensive physiological impact stems from its unique flavonoid structure, which allows it to interact with multiple biochemical targets.

Quercetin dihydrate 95% extract is widely utilized in dietary supplement formulations targeting immune support, cardiovascular health, and anti-aging applications. It is commonly incorporated into capsules, tablets, and powders, often alongside synergistic ingredients like vitamin C or bromelain to enhance absorption and efficacy. Quality considerations for this extract include rigorous testing for purity, potency, and absence of contaminants such as heavy metals and pesticides. Modern scientific research, including randomized controlled trials, has further elucidated quercetin's role. For instance, a meta-analysis published in the "Journal of Nutrition" highlighted quercetin's efficacy in reducing C-reactive protein (CRP), a marker of inflammation. Another study in "Hypertension" showed significant reductions in systolic blood pressure with quercetin supplementation. These findings, combined with extensive mechanistic studies, provide a robust evidence base for its inclusion in health-promoting products, emphasizing its potential beyond traditional uses.
