Naringin Powder

High-Purity Naringin Powder 98% – Premium Citrus Extract for Pharmaceutical & Nutraceutical Applications

Xi'an Jiayuan Bio-tech Co., Ltd., established in April 2002 with a registered capital of RMB 30 million, specializes in manufacturing pharmaceutical-grade Naringin Powder extracted from Citrus grandis. Our product is 98% pure (HPLC) and the yearly manufacturing capacity is more than 20 tonnes. We have 2 GMP certified manufacturing lines and 30 technical personnel. We produce ISO9001, HALAL and KOSHER certified extracts. CAS NO.: 10236-47-2 Molecular Formula: C27H32O14 This flavonoid glycoside is a light yellow to white crystalline powder and provides excellent thermal stability and bioactive consistency to B2B customers in over 50 countries.

What Is Naringin Powder?

This product is a standardised polyphenolic flavanone glycoside from citrus fruit peels, especially grapefruit and pomelo exocarps. It tackles the important obstacle of raw material variability for the pharmaceutical business by delivering uniform bioactive potency. This molecule is naringenin aglycone linked to neohesperidose disaccharide. It provides consistent intensity of bitterness and antioxidant capacity.

Our extraction is solvent-based using Rutaceae plant fruits as botanical sources. The substance obtained corresponds to the USP reference standards with molecular weight 580.53 g/mol. Our product has steady sensory profiles from manufacturing batch to batch, unlike crude citrus extracts, and is important for precision formulation work.

Functions

This bioactive chemical is proven by quality-controlled manufacture and has many pharmacological mechanisms:

Antioxidant & Anti-inflammatory Effect: Neutralises free radicals while suppressing NF-kB and NLRP3 inflammatory pathways. Lab testing shows it is active at all temperature fluctuations throughout processing.

Metabolic Regulation: Boosts adiponectin and AMPK signalling, favouring thermogenic formulas. Is stable when coupled with acid stimulants in metabolic accelerators.

Respiratory Support: Effective to reduce airway mucus production in therapeutic syrups High load pharmaceutical processing without degradation.

Bioavailability Enhancement: Precursor for the synthesis of Naringin Dihydrochalcone, connecting functional flavour chemistry with metabolic health applications.

Purity	98% (HPLC)
Appearance	Light yellow to white powder
Solubility	Soluble in hot water, alcohol
Melting Point	156-158°C
Moisture Content	<12%
Heavy Metals	<10 ppm total

Application Fields

Pharmaceutical Manufacturing: Processed into respiratory health preparations via antitussive characteristics. Reliable performance in capsule and syrup presentations requiring heat processing.

Nutraceutical Supplements: Key element in weight control complexes for metabolic syndrome. Sustains activity in combination with caffeine or synephrine beyond 24 month shelf life.

Functional Beverages: Used as a clean label bittering ingredient in tonic waters and craft sodas. It provides a stable sensory experience and does not fluctuate in the pH range of 2.5-4.0.

Animal Nutrition: It is used as a sensory feed addition and is recognised as safe for consumers under EU animal nutrition rules.
