Orthosiphon Stamineus Extract Powder

Orthosiphon stamineus extract starts from the leaves of Orthosiphon stamineus, the cat’s whiskers or Java tea plant, with the stem and flower spike excluded. Water extraction concentrates the soluble leaf fraction, and the liquor is dried into a light brown powder that disperses in water.

The extract is supplied at a 10:1 ratio with no marker percentage and is milled to 80 mesh. It is the whole-leaf ratio extract and is kept apart from the sinensetin-defined grade of the same leaf. Tea made from the leaf is a beverage tradition and not a regulated grade.

Orthosiphon stamineus Leaf Source & Identity

The botanical entity is Orthosiphon stamineus Benth., the Java tea of the Lamiaceae, a Southeast Asian herb with square stems, toothed leaves and spikes of pale flowers whose long stamens give the name cat’s whiskers. Some floras treat the plant as Orthosiphon aristatus. The part used is the leaf. Stem and flower spike are not part of this Orthosiphon stamineus extract.

Leaf is the standard material, and the trade names java tea and misai kucing refer to it. The leaf holds polymethoxylated flavones such as sinensetin, caffeic acid derivatives including rosmarinic acid, and potassium salts, named here only as families. Most of the flavones are poorly water-soluble.

Orthosiphon Extract vs Sinensetin Grade

Form	What It Is	Choose It When
10:1 Leaf Extract	Water-extracted, concentrated Orthosiphon stamineus leaf	The whole-leaf ratio extract is wanted
Orthosiphon Stamineus Extract 0.1–1% Sinensetin	Leaf extract defined by a sinensetin range	A stated sinensetin range is required

Both entries come from the same leaf. A water-based 10:1 extract carries the polar side of the leaf, mainly phenolic acids and potassium, while the lipophilic flavone sinensetin is only partly recovered, so the ratio extract is not a sinensetin product. A buyer who must declare sinensetin should choose the defined grade. A buyer who needs the whole-leaf polar profile at a fixed ratio can use the Orthosiphon stamineus extract and rely on the species and ratio. In short, Orthosiphon stamineus extract is the polar, whole-leaf choice, and the Orthosiphon stamineus name on a form keeps it apart from other herbal teas.

Application Areas

Capsules for Polar Leaf Extracts

Orthosiphon stamineus extract is filled into capsules as a light brown powder. Potassium salts and phenolic acids make the particles hygroscopic, so a dry filling room and a flow aid are essential, and fill weights are tracked through each run.

Java Tea-Style Instant Mixes

Instant tea-style blends build on the traditional use of the leaf as a drink. The extract dissolves to a hazy amber liquid with a mild, hay-like, slightly salty note. Lemon, ginger and honey flavors suit it, and a carrier keeps the dose even between sachets.

Tablets with Salt-Bearing Extract

Tablets carry the extract with microcrystalline cellulose and a disintegrant. The potassium content makes the granule tend to pull in water, so compression is run in a controlled room and hardness is rechecked after storage.

Fruit-Flavored Powder Sticks

Sticks pair the extract with apple or citrus flavors in barrier laminate. A salty edge from the potassium salts is covered by sweetener, and the premix is dried before filling so the powder does not clump at the seal.

Cooked Gummies with Plant Salts

Gummies take the extract late in the cooked base. Potassium salts and phenolics lend an astringent finish, so fruit flavors with some acidity cover it, and a storage trial confirms that color and texture hold.

Formulation Notes

Orthosiphon stamineus extract is a light brown powder with a faint, hay-like, tea-like aroma and a mildly bitter, slightly salty taste. In water it forms a hazy amber liquid, and fine leaf fragments settle slowly. The salty note is a distinctive sensory trait of the leaf.

Leaf extracts with soluble salts pull in water from the air and cake. Weigh the leaf powder in a dry area and close the liner after every draw, because its potassium salts draw water from the air. Surface clumping and darkening are the first signs of moisture pickup in an opened pack.

Premix the extract with a flow aid and a carrier and screen it into the bulk blend in one stage. In beverages, the poorly soluble flavone fraction can leave a slight haze or a fine sediment, so clear bottled formats are trialed before commitment, and cloudy formats are preferred.
