Narcissoside

Updated: 2026-09-20

Overview

Narcissin, chemically known as kaempferol-3-O-rutinoside, is a flavonoid glycoside predominantly extracted from plants of the Narcissus genus. It belongs to the flavonol subclass and is recognized for its bioactive properties, including antioxidant and anti-inflammatory effects. The compound is widely studied for its potential therapeutic applications, particularly in chronic disease management and skincare formulations. In industrial contexts, narcissin is sourced as a high-purity powder for use in pharmaceuticals and cosmetics. Its natural origin and multifunctional benefits make it a sought-after ingredient in B2B markets, particularly for manufacturers of nutraceuticals and dermatological products.

Physical and Chemical Properties

Narcissin presents as a yellow crystalline solid with a molecular weight of 594.52 g/mol. Its structure combines kaempferol (a flavonol) with rutinose (a disaccharide), contributing to its moderate solubility in polar organic solvents like methanol and ethanol. The compound exhibits stability under standard storage conditions but degrades under prolonged exposure to UV light or high temperatures. Key spectroscopic identifiers include UV-Vis absorption maxima at 265 nm and 365 nm, which are characteristic of flavonol glycosides. Its melting point ranges between 200-205°C, and it demonstrates negligible volatility. These properties are critical for quality control during extraction and formulation processes.

Main Applications

In the pharmaceutical industry, narcissin is investigated for its role in mitigating oxidative stress and inflammation, with preclinical studies highlighting its potential in cancer chemoprevention and cardiovascular health. It is also incorporated into nutraceuticals targeting metabolic syndrome. The cosmetic sector values narcissin for its antioxidant capacity, which helps neutralize free radicals in anti-aging serums and sunscreens. Additionally, its anti-inflammatory properties make it suitable for sensitive skin formulations. B2B buyers often procure it for R&D or as an active ingredient in finished products.

Safety and Storage

While narcissin is generally regarded as low-toxicity, occupational exposure should be minimized. Lab personnel must use PPE (gloves, goggles) to prevent contact with eyes or skin. Ingestion risks require proper labeling and secure storage in compliance with GHS guidelines. For long-term stability, the compound should be stored in airtight containers at temperatures below 25°C, with desiccants to prevent moisture absorption. Bulk quantities may require refrigeration (2-8°C) to extend shelf life beyond 24 months.

B2B Procurement Guide

When sourcing narcissin, prioritize suppliers who provide third-party purity verification (e.g., HPLC ≥98%) and full documentation (COA, MSDS). Pricing varies by quantity and purity; bulk orders (1 kg+) typically offer 10-20% cost reductions. Key due diligence includes auditing the supplier’s extraction methods (e.g., ethanol vs. supercritical CO2) and ensuring compliance with ISO 9001 or cGMP standards. Sample testing for heavy metals and residual solvents is recommended before large-scale procurement.
