Centella Asiatica Extract Powder

Centella Asiatica Extract Powder | Gotu Kola Triterpene Standardized Botanical Extract for Cosmetic & Nutraceutical Use

Shaanxi Hongda Phytochemistry Co., Ltd. produces pharmaceutical grade Centella Asiatica Extract Powder derived from Centella asiatica (L.) Urb., standardised to Asiaticoside 10%–90% by HPLC. Made from the aerial parts of the plant (CAS No. 84696-21-9), this off-white powder provides constant levels of triterpenes, including Asiaticoside, Madecassoside, Asiatic Acid, and Madecassic Acid, batch after batch. Hongda has an annual output capacity of 3,000 tons and 100,000 level purification workshops. It has been certified by KOSHER, HALAL, BRC, ISO9001, ISO22000, and ORGANIC. Hongda is a reliable supply solution for formulators in Europe, North America, and Asia.

Product Specification

Product Introduction

Gotu Kola extract — widely recognized in the phytochemistry industry as a standardized triterpene complex — addresses a persistent formulation challenge: raw Centella asiatica plant material is inconsistent in bioactive concentration and unsuitable for clinical-grade applications.

This standardized Centella Asiatica Extract Powder solves that problem. It provides stable, high-purity concentrations of pentacyclic triterpenes that raw botanical materials simply cannot guarantee. The result is predictable performance in both topical and oral formulations.

Third-Party Test Report

Every batch is tested before shipment. Shaanxi Hongda operates an SGS-standardized in-house laboratory staffed by more than 20 experienced research and testing personnel.

Testing equipment includes HPLC, GC, UV spectrophotometers, atomic absorption spectrophotometers, and automatic titrators. Each batch undergoes:

· Active content verification via HPLC

· Heavy metal testing (Pb, As, Cd, Hg)

· Pesticide residue screening

· Microbiological testing (total plate count, yeast, mold)

· Moisture and ash content analysis

Where needed, Hongda also coordinates with authorized third-party agencies — SGS and Eurofins — for pesticide residue reports, natural product declarations, and nutrition labels.

Certificate of Analysis (COA)

A full COA is provided with every order. The document covers physical parameters (appearance, particle size, bulk density, odor), chemical purity, HPLC chromatogram data, heavy metal results, microbiological counts, and shelf life.

Custom COA formats are available to match your internal quality documentation requirements. Contact the team directly to request a sample COA before placing your order.

Centella Asiatica Extract Powder Application

Cosmetic and dermaceutical formulations. Used in serums, creams, and repair balms for post-procedure skin (post-laser, post-peel). At concentrations of 0.1%–1.0%, high-purity extract has been shown in clinical data to reduce pro-inflammatory cytokines (IL-1β, TNF-α) and support re-epithelialization.

Note on solubility: Free genins (Asiatic Acid, Madecassic Acid) are lipophilic. For clear water-based serums, choose high-glycoside grades or pair with solubilizers such as Propanediol or PEG-40 Hydrogenated Castor Oil.

Oral nutraceuticals. Applied in capsules and tablets targeting chronic venous insufficiency (CVI) and microcirculation. Triterpenes survive gastric acidity and strengthen connective tissue in blood vessel walls.

Functional oral care. Incorporated into therapeutic toothpastes and mouthwashes, where the powder maintains stability in high-surfactant aqueous environments to deliver anti-inflammatory benefits to gingival tissue.

Production Process

Hongda's extraction follows a controlled sequence to protect triterpene integrity throughout:

Raw material intake → Cleaning & sorting → Solvent extraction (ethanol) → Filtration → Concentration → Spray drying → Sieving → Quality testing → Packaging

The 100,000-level purification workshop controls particulate contamination throughout drying and packaging. Steam sterilization is used for microbiological compliance — avoiding irradiation, which can degrade sensitive bioactives like Asiaticoside.

Centella Asiatica Extract Powder Advantages

Consistent active concentration. Standardized to Asiaticoside 10%–90% by HPLC, so your formulation delivers the same results every batch — no guesswork from raw plant variability.

Broad specification range. Whether you need a 10% extract for general soothing claims or a high-purity 95% grade for scar-reduction or collagen synthesis applications, the specification can be matched to your product requirement.

Clean raw material sourcing. Hongda maintains dedicated Chinese medicinal material planting bases monitored by professional agronomists. This upstream control directly reduces pesticide residue risk and supports traceability documentation.

Certified for global markets. KOSHER, HALAL, ORGANIC (EU & NOP), BRC, cGMP, FSSC22000, ISO9001, and ISO22000 Certifications are in place — reducing your regulatory review time when entering US, EU, and Asian markets.

Fast, reliable supply. With 3,000 tons annual output and a 3,000 m² warehouse running six dedicated storage zones, orders ship within 3–7 working days.

FAQ

Q1: What is the difference between standard extract and TECA grade?

A: Standard grades specify a total triterpene percentage (e.g., 10%). TECA (Titrated Extract of Centella Asiatica) meets a pharmaceutical standard requiring ~40% Asiaticoside and ~60% free genins, designed for clinical wound healing applications.

Q2: Does the powder cause solubility problems in water-based serums?

A: Free genins are lipophilic and low in water solubility. For transparent water-based serums, select a high-Madecassoside grade or use compatible solubilizers in your base formula.

Q3: Is the extract compatible with Vitamin C in the same formula?

A: Generally yes. However, at pH below 3.5, glycoside hydrolysis may occur over time. Buffering the formula or using encapsulated Vitamin C reduces this risk.

Q4: What concentration is effective for scar reduction claims?

A: Clinical data supports efficacy at 0.1%–1.0% of high-purity (95%) extract. For general soothing claims, 0.05%–0.5% is typically sufficient.

Q5: Is the powder irradiated for sterilization?

A: No. Hongda uses steam sterilization and controlled ethanol extraction to meet microbiological standards without degrading triterpene content.

Q6: Can I get a sample before placing a bulk order?

A: Yes. Sample quantities of 20–100g are available. Sample packaging uses thickened PE inner bags with an aluminum foil outer bag. Contact the team to arrange shipment.
