Introduction

For centuries, Rosehip (the fruit of Rosa canina) has been valued in traditional medicine for boosting vitality and supporting skin health, and modern scientific research has confirmed that its core active component—Vitamin C (VC)—is the key to its powerful antioxidant, immune-enhancing, and collagen-promoting effects. As a leading plant extract manufacturer, Hangzhou Greensky Biological Tech.Co.,Ltd delivers high-purity Rosehip Extract to global nutraceutical, cosmetic, food & beverage, and animal nutrition industries.

Part 1: What is Rosehip Extract?

Source Plant

Rosehip Extract is derived from Rosa canina (also known as dog rose), a deciduous shrub belonging to the Rosaceae family. Native to Europe, Western Asia, and North Africa, it is now sustainably cultivated in optimal growing regions worldwide, including Yunnan and Xinjiang (China), Chile, Argentina, and parts of North America. These areas’ abundant sunlight and moderate climate foster the synthesis of high levels of Vitamin C and other bioactive compounds.

Extracted From

The extract is primarily obtained from the ripe fruits (rosehips) of the Rosa canina shrub. Harvested in late autumn after the petals have fallen, the fruits are selected for their peak Vitamin C concentration, ensuring maximum potency in the final product.

Active Components

The core indicator component of our Rosehip Extract is Vitamin C (VC), standardized to 5%. Beyond VC, the extract contains synergistic bioactive compounds including polyphenols (gallic acid, catechins), carotenoids (Lycopene, beta-carotene), and flavonoids—all of which enhance the extract’s overall health benefits and stability.

Standardized Specification

Our flagship Rosehip Extract is standardized to 5% Vitamin C (measured via titration or HPLC), the most in-demand specification for commercial applications. We also offer customized concentrations ranging from 3% to 10% VC, as well as water-soluble powder, liquid extract, and oil-dispersible formulations to meet diverse product development needs.

Testing Report

Every batch of our Rosehip Extract is accompanied by a comprehensive Certificate of Analysis (COA). Key test results include VC content, heavy metals (lead, arsenic, mercury, cadmium), pesticide residues, microbial contaminants (total aerobic bacteria, yeast, mold, E. coli), moisture content, and pH value—all fully compliant with international standards (USP, EP, FCC, and FDA regulations).

Part 2: Key Health Benefits and Mechanisms of Action

Rosehip Extract’s 5% VC content underpins its scientifically validated benefits, with each effect supported by credible research:

Potent Antioxidant Protection: Vitamin C acts as a powerful free radical scavenger, neutralizing reactive oxygen species (ROS) that cause cellular damage and accelerate aging. A study published in PubMed demonstrated that Rosehip Extract’s VC and polyphenols work synergistically to reduce oxidative stress by 30% in human cell cultures, protecting against chronic disease development.

Enhanced Immune Function: VC stimulates the activity of immune cells (lymphocytes, macrophages) and enhances the production of cytokines (IL-2, IFN-γ), which regulate immune responses. Research in the Journal of Nutrition confirms that Rosehip Extract supplementation supports immune defense, reducing the duration and severity of seasonal discomfort.

Skin Health & Collagen Synthesis: VC is an essential cofactor for collagen production, a protein that maintains skin elasticity and firmness. A clinical trial cited in the Journal of Cosmetic Dermatology found that topical application of Rosehip Extract (5% VC) improved skin hydration, reduced fine lines, and faded hyperpigmentation by promoting collagen synthesis and inhibiting melanin production.

Anti-Inflammatory Effects: VC and rosehip polyphenols inhibit the expression of pro-inflammatory mediators (TNF-α, IL-6) and COX-2 enzymes, alleviating chronic inflammation. Studies show this makes the extract beneficial for joint comfort and reducing skin redness.

Supports Iron Absorption: Vitamin C enhances the bioavailability of non-heme iron (from plant-based foods), making Rosehip Extract a valuable addition to supplements targeting iron deficiency. Research in the American Journal of Clinical Nutrition validates this synergistic effect.

Part 3: Wide-Ranging Application Industries

Our high-quality Rosehip Extract (5% VC) is a versatile ingredient for diverse sectors:

Dietary Supplements and Nutraceuticals: Used in capsules, tablets, and powdered supplements formulated for immune support, antioxidant defense, collagen promotion, and iron absorption enhancement.

Functional Foods and Beverages: Incorporated into fruit juices, smoothies, herbal teas, energy bars, and fortified cereals to add natural Vitamin C and antioxidant benefits, appealing to health-conscious consumers.

Cosmetics and Personal Care: A premium natural ingredient in anti-aging serums, moisturizers, facial masks, and brightening creams. Its VC content boosts collagen, fades dark spots, and protects skin from environmental stressors.

Animal Nutrition: Used as a feed additive for livestock and companion animals to enhance immune function, improve skin and coat health, and support overall vitality—particularly in poultry, swine, and dogs.

Part 4: How to Choose a High-Quality Rosehip Extract

Selecting a reliable Rosehip Extract supplier requires focusing on these critical quality and safety factors:

Standardization and Purity: Ensure the extract is standardized to a clear VC content (e.g., 5%) and free from synthetic VC additives, fillers, or adulterants. Request a detailed COA to verify potency and natural origin.

Advanced Extraction Technology: Opt for suppliers using gentle, efficient extraction methods—such as our proprietary water-based extraction and low-temperature spray-drying process—to preserve VC integrity and maximize bioavailability (heat-sensitive VC is protected from degradation).

Comprehensive Third-Party Testing: Reputable suppliers provide independent lab reports for heavy metals, pesticides, microbes, and VC content, ensuring product safety and compliance with global regulations.

Sustainable Sourcing and Certifications: Choose manufacturers with ethical sourcing practices (e.g., organic farming partnerships) and certifications like GMP, ISO 9001, Organic, Kosher, or Halal to meet diverse market demands.

Supplier Expertise: Prioritize companies specializing in plant extracts, as they can offer technical support, formulation guidance, and tailored solutions for your specific application (e.g., stabilizing VC in liquid products).
