Tetradium Ruticarpum Extract Powder

Tetradium ruticarpum extract starts from the fruit of a small deciduous tree of the citrus family, known in Chinese materia medica as wu zhu yu. Water extraction concentrates the soluble fruit fraction, and the liquor is dried to a light brown powder.

The extract is supplied at a 10:1 ratio with no marker percentage and is milled to 80 mesh. No other form of this fruit is listed, so this ratio extract is the single entry for buyers who need Tetradium ruticarpum fruit in a water-dispersible powder.

Tetradium ruticarpum Identity & Plant Part

The botanical entity is Tetradium ruticarpum (A.Juss.) T.G.Hartley, a small tree of the Rutaceae, formerly filed as Evodia rutaecarpa. The part used is the fruit, a small, rounded, five-lobed capsule collected before it opens. Leaves, bark and roots are not part of this ingredient. Fruit size and maturity vary between lots and affect the chemistry.

The best-known constituents are indoloquinazoline alkaloids such as evodiamine and rutaecarpine, together with limonoid bitter principles and a volatile oil, named here as families only. Those alkaloids dissolve poorly in water, so a Tetradium ruticarpum water extract is not an alkaloid concentrate, and no alkaloid percentage is stated on this entry.

What 10:1 Means for Tetradium

The 10:1 ratio describes how much dried Tetradium ruticarpum fruit is concentrated into the extract. It is not an evodiamine or rutaecarpine figure, because the water-soluble fraction carries mostly other material such as bitter limonoids, sugars and phenolic compounds. With no powder or graded sibling listed, the ratio extract is the only way to specify the fruit here, and the Latin name should appear in every specification line. Because the fruit is small and bitter, the extract is usually blended at low inclusion and masked with strong flavors. Searches for the older Evodia rutaecarpa name lead to the same plant, which is why both names appear in supplier lists.

Application Areas

Capsule Fills for Evodia Fruit

Tetradium ruticarpum extract fills two-piece capsules as a free-flowing light brown powder after a small flow aid. Its bitter, aromatic taste stays inside the shell, which makes capsules the main format. Each finished capsule lot is checked for weight uniformity and disintegration.

Coated Fruit Extract Tablets

Tablets compress the extract with cellulose filler and a disintegrant, then take a film coat to cover the bitter taste and the faint citrus-resin smell. Dry granulation keeps heat off the powder, and hardness is tested on the coated tablet before packing.

Spiced Tea-Style Instant Mixes

Instant mixes combine the Tetradium ruticarpum extract with ginger, cinnamon and jujube flavors that stand up to its bitterness. The cup is a hazy tan liquid. A small sweetener share improves acceptance, and the dry premix is sealed quickly after filling.

Botanical Stick-Pack Blends

Stick packs pair the extract with other plant extracts, a sweetener and a carrier. The bitter edge calls for strong flavors, so trial blends are tasted before scale-up. A sieve step removes lumps ahead of filling, and mixing time is fixed to protect dose evenness.

Dark Bar Premixes

Bars take the Tetradium ruticarpum extract in the dry blend with cocoa, nuts and dates, which hide most of the bitterness. The powder is premixed with dry ingredients before any syrup is added, and finished bars are checked for moisture, shade and taste.

Formulation Notes

Tetradium ruticarpum extract is a light brown powder with a faint aromatic, citrus-peel aroma and a bitter, lingering taste. In water it disperses to a hazy tan liquid, and a little fine sediment forms on standing and re-suspends with a brief stir. The bitterness is the practical limit on inclusion in flavored formats.

The powder picks up moisture at a moderate rate, so weigh it in a dry room and reseal the pack after each draw. A flow agent smooths capsule filling. Opened packs keep their shade best when stored in a closed container, away from direct light and heat.
