Description

Larrea Divaricata, Ext. is a standardized botanical extract derived from the leaves of the creosote bush, a plant native to arid regions of the Americas. This extract is valued for its complex profile of bioactive compounds, including potent antioxidants and lignans such as nordihydroguaiaretic acid (NDGA). It serves as a critical raw material for industries requiring natural, plant-based actives with specific functional properties. Key sectors utilizing this extract include nutraceuticals, cosmetics, and advanced material science.

Application

• Nutraceutical & Dietary Supplements: Formulated into capsules and tablets for its antioxidant properties and support for metabolic health.
• Cosmetic & Personal Care: Incorporated into anti-aging serums, creams, and lotions as a natural preservative and skin-conditioning agent.
• Functional Foods & Beverages: Used as a natural preservative and functional ingredient in health-focused food and drink products.
• Pharmaceutical Intermediates: Serves as a starting material or active pharmaceutical ingredient (API) intermediate for further chemical synthesis.
• Industrial Preservatives: Applied in non-food industries, such as coatings or lubricants, to inhibit oxidation and extend product shelf life.
• Research & Development: Supplied to academic and industrial laboratories for pharmacological, biochemical, and material science studies.

Quality Control

Our Larrea Divaricata Extract is produced under strict quality management systems. Each batch is tested to verify identity, potency (typically assayed for NDGA content via HPLC), and the absence of specified contaminants such as heavy metals, pesticides, and residual solvents. Certificates of Analysis (COA) documenting these results are provided to ensure traceability and compliance with relevant standards for botanical ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and potency.
