Black Rice Extract (C3G & Anthocyanins) | USP/EP Grade

What is USP/EP Grade Black Rice Extract?

USP/EP Grade Black Rice Extract is a pharmaceutical-grade, highly bioavailable botanical ingredient derived from the seed coat (pericarp(1(1(1(1) of black rice (Ориза сатива L.). It is systematically manufactured to strictly satisfy the chemical identity, assay potency, and purity specifications outlined in the United States Pharmacopeia (USP) and the European Pharmacopeia (EP). Standardized to high concentrations of Цианидин -3- о-глюкозид (C3G) and total anthocyanins, this ingredient features a 100% clean-label molecular profile completely free from synthetic fortifications or artificial color adulteration.

Технология "зеленый источник" manufactures this pharmacopoeia-grade extract using a validated, eco-friendly water-ethanol extraction technology designed for highly sensitive healthcare formulations. To guarantee compliance with USP/EP monographs, our production process enforces ultra-low heavy metal limits (Pb ≤ 2.0 ppm, As ≤ 1.0 ppm) and rigorous microbiological controls. Every supply batch delivers zero toxicity risk and organic solvent-free purity, rendering it a certified active nutrient optimized for global pharmaceutical, capsule, and dietary supplement manufacturing.

Technical FAQ

Q1: How does Green Spring Technology verify the chemical identity of the anthocyanins to prove zero synthetic dye adulteration for compliance with USP/EP standards?

A1: We confirm botanical authenticity by matching the signature Cyanidin-3-O-glucoside (C3G) peak with the official USP/EP Standard Reference via HPLC-DAD fingerprinting. This rigorous chromatographic mapping systematically detects and eliminates any risk of synthetic color fortification, ensuring an uncompromised, 100% clean-label active pharmaceutical profile.

Q2: Given that anthocyanins are highly sensitive to processing, how do you guarantee that your USP/EP Grade powder achieves optimal bioabsorption and stability?

A2: We deploy low-temperature vacuum isolation to strictly control the molecular polymerization range, keeping the anthocyanins primarily in their highly active, low-molecular-weight monomeric form. This precise structural preservation yields a 100% instantly water-soluble powder with zero precipitation and delivers a 30% higher stability rate against thermal color fading.

Q3: For sensitive cardiovascular and neural formulations, how does your quality control framework address the strict USP <561> and heavy metal thresholds?

A3: Our laboratory utilizes advanced ICP-MS technology to restrict elemental impurities to pharmaceutical-grade levels of Pb ≤ 1.0 ppm, As ≤ 0.5 ppm, and Cd ≤ 0.2 ppm. Additionally, every batch undergoes multi-residue screening to guarantee 100% compliance with USP <561> and EU EC 396/2005 (MRLs ≤ 0.01 mg/kg).
