Aerva lanata Extract 3% Polyphenols

Aerva lanata extract is prepared from the dried aerial parts of Aerva lanata, the woolly, pale-flowered herb called polpala or kapok bush in South Asian herbal use, and not from the rhizome of Bergenia ligulata, which carries a similar local name. Ethanol extraction concentrates the phenolic fraction of the herb, and the liquor is dried to a light brown, water-soluble powder.

The grade is 3% polyphenols by UV using the Folin-Ciocalteu reagent. The powder is 80 mesh. It is meant for capsules, tablets, drink mixes and herbal blends in which a measured phenolic content is wanted within the character of a whole-herb extract.

Polyphenol Standardization & Grades

The phenolic content of this herb is a mixed class dominated by flavonol glycosides, mainly of kaempferol and quercetin, accompanied by phenolic acids. The grade sums the class without naming one compound, because the herb has no single dominant marker. The botanical entity is Aerva lanata (L.) Juss. ex Schult., a name that GBIF lists as a synonym of Ouret lanata. The part used is the aerial herb, which the master data groups with leaf and herb.

A 3% polyphenol content is modest, and the powder is best viewed as a whole-herb extract with a defined phenolic floor, not a polyphenol concentrate. The remaining weight is made up of soluble carbohydrates, minerals, small amounts of alkaloids and sterols, and the pale pigments of the herb. The page carries one grade, so there is no ladder of tiers, and the decision concerns dose, color and taste.

No sibling product from the same plant is currently listed in the catalog, and the nearest relatives for a formulator are other herbal extracts graded by total polyphenols. A formulator who needs a much higher phenolic load should consider an extract of a polyphenol-rich botanical, such as tea or apple. One who wants the character of this herb will value the whole-herb profile at a defined level.

Buyers who compare Aerva lanata extract quotes should check the name carefully. The Sanskrit name pashanbheda is applied to several unrelated plants, among them Bergenia ligulata and Aerva lanata, and the two have entirely different chemistry. A botanical name, the part and the method are the items that make a polyphenol figure comparable between suppliers.

Polyphenol Analysis & Purity Risks

The grade is measured by UV with the Folin-Ciocalteu reagent, a colorimetric method in which phenolic hydroxyl groups reduce the reagent to a blue complex read at a fixed wavelength. The result is a measure of reducing capacity, usually expressed as an equivalent of one reference phenol such as gallic acid, and the reference should be named when quotes are compared. An HPLC result for one flavonoid glycoside is a different measurement and cannot be converted into it.

The reagent is not specific. Ascorbic acid, some amino acids and certain proteins also reduce it, so a powder that contains such substances reads higher than its true phenolic content. In a leafy herb extract these interferences are usually small, but a poorly cleaned extract with a high sugar or protein load can shift the reading, and a validated sample cleanup keeps it honest.

The chromatographic fingerprint of the herb shows a group of kaempferol and quercetin glycosides in the middle of the run and phenolic acids earlier. The pattern is characteristic enough to distinguish the herb from the Bergenia rhizome, which is rich in bergenin, a compound that Aerva lanata does not carry in comparable amounts.

Purity risks follow from the botany and the trade names. Aerva javanica and Aerva sanguinolenta are related species with similar looks, and the whole plant, including stems and inflorescences, enters the commercial herb. A species statement, the aerial parts as the stated part and a fingerprint protect identity better than one total polyphenol percentage.

Applications by Grade

3% Grade for Capsule Fills

The single 3% grade is dosed by weight in capsules, so a typical formula needs a generous fill to reach a phenolic target. The light brown powder is fine and hygroscopic, which means a dry filling room and a flow agent are needed, and fill weights should be checked at the start of each run.

Drink Sticks With Herbal Flavors

Because the powder is water soluble, the grade dissolves into a clear to slightly hazy amber solution with a mild, grassy taste. A lemon or ginger flavor system balances the herbal note, and a small amount of acid keeps the polyphenols pale and stable.

Tablet Blends With Herbal Extracts

Tablets suit the grade when it is blended with other herbal extracts at moderate inclusion. The hygroscopic matrix softens compacts in humid rooms, so a dry binder, a moisture-protective film coat and a hardness check after storage are the main controls.

Herbal Tea-Style Mixes

Instant tea-style mixes carry the grade with chamomile, mint or hibiscus. The extract gives a pale gold color and a light herbal body, and its mild taste does not compete with the flavor of the other ingredients, which allows a comparatively high inclusion level.

Dry Compound Premixes

Dry premixes combine the extract with bulking agents and other herbal powders. Pre-mix it with a portion of the carrier so the fine powder spreads evenly, and screen the blend before filling, because the soluble matrix absorbs moisture and forms lumps.

Technical & Quality Considerations

The extract is a light brown powder with a faint grassy odor and a mild, slightly bitter taste. It is water soluble, so it dissolves into a clear to slightly hazy amber solution that deepens in color as the concentration rises. Flavonol glycosides are reasonably stable in dry form and in acidic to neutral solutions, though they darken slowly in light and at high pH.

Polyphenols react with iron to give dark complexes, so use stainless steel equipment. The soluble carbohydrate matrix of the herb draws water from the air, so open drums only briefly and re-seal them with the liner in place. At production scale, screen the Aerva lanata extract before dosing and pre-mix it with a portion of the carrier to avoid lumps.

A retained sample from each lot serves as the reference for color, odor and flow. A darker shade than the retained sample can indicate oxidation or moisture uptake, and a short check of the drum seal and storage conditions usually finds the cause. Clean mixers between this powder and pale products, since the light brown tint carries over visibly at low levels.
