Gotu Kola Extract Powder

Excellence in Advanced Manufacturing

Shaanxi Rebecca Biotechnology has state-of-the-art facilities that are equipped with ultra-fine grinding and high-temperature drying technology. Our 100,000-grade sterile setting makes sure that output is free of contamination.

Full Quality Control Systems

We keep our cGMP, ISO9001, ISO22000, FSSC22000, HACCP, HALAL, and KOSHER standards up to date. A third party checks each batch for heavy metals, chemical leftovers, and microbe contamination.

The ability to customise

Our research and development team helps OEM/ODM projects by making Gotu Kola Extract Powder, pills, and capsules, among other dose forms. We change the specs to fit the needs of your recipe.

The Global Supply Chain

Our effective transportation system sends goods safely all over the world. We carefully handle our product to make sure that it is always available for big sales.

Source of Raw Material

We get the best Centella asiatica whole plant from licensed growers in Guangxi and Yunnan, China, as well as from approved sellers in Indonesia and Madagascar. Harvesting happens during the busiest growing seasons, when the amount of asiaticoside is at its highest.

Grade Classification

· Brought in from Southeast Asia under strict rules for heavy metals and pesticides

· Organic Grade: Certified by USDA and ECOCERT, with full paperwork for tracking

· Standard Grade: Low-cost local production that meets international safety standards

There is full proof of ownership for each lot, from the field to the final product.

Characteristics of Solubility

This extract is easy to mix with ethanol (>50%), hot water, and propylene glycol. Solubility is average in cold water; gentle boiling makes spread better. The 200-mesh particle size makes the solution more stable in water-based mixtures.

Stability Parameters

· Temperature: Stays strong up to 80°C; long-term contact above 90°C leads to slow breakdown

· pH Range: Stability is best between 4.0 and 7.2; don't let it get too acidic or alkaline.

· Sensitivity to light: dry Gotu Kola Extract Powder stays stable when kept out of direct sunlight; liquid solutions need to be packaged in a way that keeps them out of light.

· Hygroscopicity: Doesn't absorb much water when kept correctly; use covered containers in places with controlled humidity.

1. Raw material prep: Select and clean raw materials, dry at low temperature (45–60°C) to moisture ≤10%, and perform HPLC pre‑screening.

2. Enzymatic treatment: Add cellulase and incubate at 32–35°C for 24 hours to optimize cell wall breakdown.

3. Extraction: Reflux with 75% ethanol at 75–80°C for 3 cycles to ensure complete dissolution of asiaticoside.

4. Concentration: Evaporate under vacuum at 60°C to prevent thermal degradation of active compounds.

5. Purification: Apply multi‑stage resin chromatography to remove polysaccharides and pigments.

6. Refinement: Use solvent extraction and decolorization to achieve the target purity of 98%.

7. Drying: Dry under vacuum at low temperature (45°C) to preserve bioactive integrity.

8. Milling: Pulverize with airflow to 200 mesh for uniform particle distribution.

There are several levels of proof in our standard system. HPLC research shows the presence of asiaticoside and finds possible contaminants. Heavy metals can be found with ICP-MS tests at a resolution of parts per billion. GC-MS testing makes sure that liquid leftovers meet EU standards. The USP guidelines for total plate count, yeast, mould, and bacteria are used for microbiological tests. We include full Certificates of Analysis with every package and can help with third-party approval through SGS or similar labs if you ask. Full traceability from harvest to delivery makes sure that your whole supply chain is clear.

Packaging as Standard

Each unit has 25 kg of net weight in aluminium foil bags inside fibre drums that are vacuum-sealed. During storage and transport, this two-layer method keeps out wetness, light, and air.

Your Choices

We can meet your specific packaging needs, such as smaller sizes (1 kg and 5 kg), private labelling, and special cases for recipes that are sensitive.

How to Ship Things

Air freight (3–7 days) or ocean freight (cheaper for large orders) are the two ways that international orders are sent. As needed, we organise paperwork like MSDS, COA, and phytosanitary licenses.

Q: What's the difference between various asiaticoside concentrations?

A: Higher amounts, like 98%, go through more steps of processing to get rid of sugars and other impurities. This makes them more stable and less likely to absorb water than 10–20% grades.

Q: Will this powder clump during humid conditions?

A: Our moisture-barrier packaging keeps things from sticking during normal shipping. Keep unused packages below 25°C and below 55% humidity for the longest shelf life.

Q: Can you adjust specifications for specific applications?

A: Yes, we can change the amount of glycosides, the particle size (60–300 mesh), and the package style to fit your specific needs while still providing a steady big number of products.

Q: How does solubility affect formulation?

A: The 200-mesh ultrafine grade mixes well with warm booze and water. For cold water-based mixtures, propylene glycol and other co-solvents can help the ingredients spread out better.

Q: What documentation supports regulatory compliance?

A: Each batch comes with a certificate of analysis (COA) that has full scientific data, allergy labels, non-GMO approval, and proof that it meets EU EC396 and EU 2023/915 standards.
