Centella asiatica extract

Centella asiatica extract suppliers and sourcing guide

Centella asiatica extract is made from the leaves and aerial parts of Centella asiatica, a low creeping plant in the carrot family grown in South and Southeast Asia and Madagascar. Suppliers extract the dried herb with water, glycols or ethanol and sell either broad extracts in a carrier or purified fractions standardized to triterpenes such as asiaticoside, madecassoside, asiatic acid and madecassic acid. Brands buy liquid extracts for general formulas and standardized powders where a set triterpene content matters.

Forms and grades of centella asiatica extract

Suppliers sell different products under the same name. Specify the one you need.

  • Glycol or glycerin extract

    Liquid extract in butylene glycol, propylene glycol or glycerin and water, sold at a stated plant-to-extract ratio. Carrier and preservatives belong on the INCI list.

  • Standardized triterpene powder

    Purified extract standardized to total triterpenes or to named compounds, often sold as titrated extract of Centella asiatica (TECA).

  • Leaf water

    Centella leaf water or hydrosol, used as a water-phase replacement at low active content.

  • Organic

    Extracts from certified organic herb, usually in glycerin or water carriers.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Triterpene assay
Asiaticoside, madecassoside, asiatic acid and madecassic acid by HPLC, reported individually or as a total.
Identity
HPTLC fingerprint against a reference, plus Latin name and plant part on the COA.
Solids, pH and appearance
Dry residue, pH and color for liquid extracts, which show extract strength and stability.
Heavy metals
Lead, arsenic, cadmium and mercury by ICP-MS; this plant grows in wet ground and can take up metals.
Pesticide and solvent residues
Pesticide residue screen, and residual ethanol or other solvents for powders made by solvent extraction.
Microbiology
Total aerobic count, yeast and mold, and pathogens, important for water-based extracts.

Storage, lots and expiry

Storage and shelf life

Store liquid extracts closed, cool and out of light, and powders sealed and dry; standardized powders are hygroscopic. Avoid repeated warming of liquid extracts, which can darken or precipitate. Shelf life comes from the supplier's specification, with retest of triterpene assay and micro for older stock.

Lots and expiry dates

Triterpene content varies with harvest, origin and extraction, so record the actual assay for each lot and the carrier ratio for liquids. Expect color and odor to differ between lots of liquid extract.

Regulatory status

Facts from regulators and standards bodies, each linked to its source.

  • The EU Novel Food Catalogue entry for Centella asiatica records that an extract standardized to 40% triterpenes was considered a novel food after a consultation request to the Czech competent authority.
