Ganoderma Triterpene1-6%
Ganoderma triterpene 1-6% is a reishi mushroom extract sold on a declared content of lanostane-type triterpenoids, standardised anywhere between one and six percent depending on the grade ordered. The triterpenoid fraction is a large family of oxygenated lanostane skeletons, of which the best characterised are ganoderic acids A, B, C and D and the related ganoderenic and lucidenic acids. It is the fraction responsible for the pronounced bitterness of reishi.
Unlike the beta-glucan polysaccharides of a water extract, triterpenoids are poorly soluble in water and are recovered with ethanol, which sets the manufacturing route. The finished ingredient is a fine powder, mid to dark brown and noticeably darker than a plain water extract, with a strong bitter taste and an earthy mushroom aroma. Assay is determined by HPLC against ganoderic acid A or, in older specifications, by a spectrophotometric method calibrated to oleanolic acid, and the two methods do not give the same number for the same material.
The powder is hygroscopic and cakes if exposed to humid air. It disperses rather than dissolves in cold water and goes into solution readily in ethanol and hydroalcoholic systems. The triterpenoid fraction is reasonably heat stable in acid to neutral conditions but degrades under prolonged alkaline heating.
We source bulk Ganoderma Triterpene1-6% from top China manufacturers for our partners. The manufacturer is in Shaanxi. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
The commercial ladder runs in steps. One and two percent grades are the volume products, usually made from fruiting body and blended with a small carrier load. Four percent is the common mid grade for capsule and tablet supplements. Six percent, and occasionally higher, is a concentrated grade that needs a more selective ethanol fraction and a higher raw material input, and is priced accordingly. Buyers should confirm which assay method a stated percentage refers to, since HPLC and colourimetric figures are not interchangeable.
Alongside the triterpene number, grades differ in whether the polysaccharide fraction is also declared. Dual extracted products carry both figures, for example 30 percent polysaccharide with 4 percent triterpene. Raw material origin is a further split, with fruiting body, mycelium and shell-broken spore lines traded separately. Physical options are 80 mesh standard powder and 100 to 200 mesh fine powder for tablet blends, with organic certified lots run separately.
Applications
- Capsules and tablets in the supplement trade, where the triterpene figure is the label claim the product is sold on
- Dual extract reishi supplements, blended with a water extract so both polysaccharide and triterpene claims can be made
- Tinctures and liquid supplements, where the ethanol base keeps the triterpenoid fraction in true solution
- Mushroom blend powders combined with chaga, cordyceps and lion's mane for stacked positioning
- Soft gel and liquid capsule fills, dispersed in oil or glycerine carriers
- Gummies and chewables, dosed low and paired with strong fruit acids and flavours to cover the bitterness
- Traditional Chinese herbal formulations and tonic preparations, where the bitter reishi character is expected rather than masked
- Bitter tonic and amaro style beverages, used at trace levels as a botanical bittering agent
- Cosmetic and topical serums, where triterpenoid-rich fractions are used in anti-ageing positioning

Regulatory Status
In the United States reishi triterpene extracts are used as dietary ingredients under DSHEA. Reishi itself is treated as a botanical present in the food supply before 1994, so a conventional hydroalcoholic extract is not normally the subject of a new dietary ingredient notification, though a highly concentrated or unusually processed fraction can raise that question. Use in conventional foods rather than supplements depends on a GRAS conclusion covering the specific preparation and use level. Structure and function claims are permitted with the required disclaimer, and disease claims are not.
In the European Union the extract is a food ingredient, not a food additive, so it carries no E number. An ethanol extract of the fruiting body is generally regarded as having a history of significant consumption in the EU before May 1997, but a highly enriched triterpenoid fraction is more likely to be assessed as a novel food and to need authorisation under the Novel Food Regulation before it can be placed on the market. Health claims are confined to the authorised list, which does not include reishi. Residual ethanol has to be controlled to the limits set for extraction solvents in food. Codex has no commodity standard for this material, so specifications are set by contract.
Manufacturing Process
Dried Ganoderma fruiting bodies are milled to a coarse powder and loaded into percolation or reflux extractors charged with 70 to 95 percent ethanol. A higher ethanol strength favours the triterpenoid fraction and leaves most of the polysaccharide behind in the marc, which is why the target assay largely sets the solvent strength and the number of extraction passes. The extract is drawn off, the marc is washed, and the combined liquor is filtered to remove fines.
Ethanol is stripped in a vacuum evaporator and recovered for reuse, leaving an aqueous-organic residue. Where a higher assay is required this residue is polished further, typically by macroporous resin adsorption in which the resin retains the triterpenoids while sugars and salts pass through, followed by an ethanol elution. The purified liquor is concentrated, blended with a small quantity of carrier such as maltodextrin or dextrin to control hygroscopicity, and spray dried or vacuum belt dried. The powder is milled, sieved, assayed by HPLC and blended down to the exact declared percentage before packing under a foil laminate liner.
