Explore our primary certified botanical extracts, biological enzymes, and dietary supplement formulations.
Citrus flavonoids represent a diverse subclass of polyphenolic compounds abundant in citrus fruits such as sweet oranges, lemons, grapefruits, limes, and bitter oranges. Chief among these compounds are Hesperidin, Diosmin, Naringin, Neohesperidin, Eriocitrin, and Polymethoxyflavones (PMFs) like Nobiletin and Tangeretin. In modern pharmacology, nutraceutical sciences, and clinical nutrition, these phytochemicals have emerged as core components for combatting oxidative stress, supporting cardiovascular integrity, regulating glucose metabolism, and fostering balanced immune responses.
As leading citrus flavonoids exporters, Shaanxi ShineHerb Biotech Co., Ltd. applies advanced chromatographic isolation techniques to yield standardizations that meet international pharmaceutical and dietary supplement criteria. By targeting molecular pathways such as NF-κB, AMPK, and Nrf2, our standardized extracts deliver measurable physiological support, answering the global demand for therapeutic, science-backed botanical ingredients.
We supply standardized Citrus Bioflavonoid complexes ranging from 30% to 90% bioflavonoids (HPLC/UV), alongside isolated single-molecule profiles:

Understanding the structural shifts in botanical API procurement, consumer trends, and ingredient selection.
Brands are moving away from synthetic antioxidants in favor of botanical compounds like citrus bioflavonoids. Incorporating natural extracts alongside Vitamin C significantly increases absorption dynamics, offering a clean-label formulation edge for immune support products.
With obesity and metabolic syndrome on the rise worldwide, clinical interest in the cardiovascular benefits of Hesperidin and Diosmin is soaring. Global pharmaceutical and nutraceutical buyers are securing high-purity active ingredients to target venous health and glycemic control.
Traditional raw plant materials often suffer from poor absorption. The market is demanding micro-milled and micronized particle sizing, liposomal complexes, and cyclodextrin carriers to improve bioavailability in functional beverages and quick-release capsules.
How ShineHerb Biotech secures reliable raw materials through vertical testing protocols and global standards.
Quality is the core of a company's survival and development. ShineHerb Biotech has established a strict quality management system, covering raw material inspection, production process control, solvent and excipient management, and final product testing, ensuring rigorous quality control at every stage.
Our raw material testing protocols align strictly with international monographs: United States Pharmacopeia (USP), European Pharmacopoeia (EP), and Chinese Pharmacopoeia (CP). By monitoring critical contamination points, we keep heavy metal limits (Pb, Cd, Hg, As), residual solvents, and pesticide residues well within regulatory thresholds.

Our state-of-the-art facility uses eco-efficient extraction methodologies designed to optimize output purity while keeping environmental impact low.
We utilize hydro-ethanolic solvent mixtures at controlled temperatures to prevent thermal degradation of delicate polyphenol structures during raw material processing.
Advanced macroporous adsorption resins isolate targeted bioflavonoids, removing impurities like plant sugars, lipids, and unwanted pigments to increase final concentration.
Low-temperature concentration paired with rapid spray-drying systems yields a fine powder with excellent flowability, compressibility, and water-dispersion properties.
To help brands reduce time-to-market, ShineHerb Biotech offers a comprehensive contract manufacturing platform. We transform raw botanical powders and chemical compounds into consumer-ready form factors, working under GMP-certified conditions to ensure quality every step of the way.
High-speed tablet pressing and hard-shell encapsulation (gelatin or vegetable HPMC). Ideal for standardized complexes like Hesperidin/Diosmin combinations.
Pectin or gelatin-based delivery forms customized for flavor, shape, and active ingredient stability. Excellent for child-friendly or pill-fatigue conscious consumer lines.
Flavored dry-mix formulations featuring micronized bioflavonoids and enzymes designed for fast reconstitution and pleasant taste profiles.
