A high-purity botanical powder can look simple on a specification sheet, but small wording differences can change what a buyer receives. For formulators and purchasing teams working with Sophora japonica, the grade, plant part, assay method, and active marker all matter.
Sophora Japonica Fruit Extract Powder 98% Kaempferol should be treated as a clear purchasing specification, not as a loose name for any Sophora japonica extract. A 98% Kaempferol grade is different from a 30% Kaempferol grade, a flower extract rich in luteolin, a ratio extract, or raw botanical powder.
A Clover Nutrition Inc supplies Sophora Japonica Fruit Extract Powder Kaempferol 98%, with 11 years of focus on high-purity ingredients and cosmetic raw materials. The stated specification is based on botanical identity, plant part, offered grade, test method, and assay result.
What this ingredient specification means
The key specification is:
Specification point | Declared detail |
Botanical identity | Sophora japonica L. |
Plant part | Fruit |
Offered grade | Kaempferol 98% by HPLC |
Assay result | 98.07% |
Supplier | A Clover Nutrition Inc |
Focus | 11 years on high-purity ingredients and cosmetic ingredient raw materials |
This level of detail is useful because it reduces ambiguity. “Sophora Japonica Extract” alone is not enough for serious approval work. It could refer to different plant parts, different marker compounds, different assay levels, or different extraction and purification targets.
The active marker here is Kaempferol, a naturally occurring flavonoid found in a range of plants. In this case, the purchasing target is a high-purity Kaempferol powder derived from Sophora japonica fruit, with the grade confirmed by HPLC.
Mentioning HPLC matters. High-performance liquid chromatography is commonly used to identify and quantify active marker compounds in botanical extracts. For a 98% grade, the test method and assay result help separate a defined high-purity ingredient from a more general botanical extract.
For procurement notes, Kaempferol, Sophora Japonica Fruit Extract, A Clover Nutrition Inc should refer to this specific high-purity fruit extract grade, not a broader category of Sophora japonica materials.
Why the plant part must be checked
Sophora japonica is used as a botanical source for several flavonoid ingredients, but different plant parts may be associated with different target compounds. That is why “fruit” and “flower” should never be glossed over.
For this ingredient, the plant part is fruit. That detail supports the identity of the material and helps distinguish it from Sophora japonica flower extract grades, including luteolin-focused materials.
The difference can affect:
The target active compound
The expected assay profile
The specification sheet
The matching of samples with purchase orders
The internal approval file
The naming used in formula records
A buyer requesting Sophora Japonica Fruit Extract Powder Kaempferol 98% should not approve a flower extract simply because it also comes from Sophora japonica L. The botanical species is only one part of the specification. The plant part and active grade complete the picture.
Why Kaempferol 98% is not the same as lower-strength extract
The phrase “98% Kaempferol” describes a high-purity ingredient. It should not be used interchangeably with a 30% Kaempferol extract or a generic ratio extract.
Lower concentration grades can be useful in some product concepts, but they do not serve the same role in purchasing, testing, or formulation records. If a formula is built around a 98% active marker level, replacing it with a 30% grade would change the active input level and the carrier or matrix contribution.
That can create practical issues:
The formula may need a different use level.
The sensory profile may change.
Colour impact may differ.
The ingredient declaration process may need review.
Quality control tests may no longer match the approved standard.
Cost comparisons may become misleading.
A 98% material usually calls for tighter handling and more careful weighing, especially in small-batch development. The benefit is clear specification control. The trade-off is the need for careful documentation and batch verification.
For Clean Beauty Formulations, Cosmetic Ingredients teams often prefer defined botanical actives because they make it easier to check what has been approved, tested, and added to the formula. A clear assay can support more consistent development work than a vague botanical extract name.
Compare related grades before approval
Before confirming a purchase order, compare related Sophora japonica grades side by side. Similar names can cause costly mistakes.
Related material | Main distinction | Approval note |
Sophora Japonica Flower Extract Powder 95% Luteolin | Flower-derived extract with luteolin as the key marker | Not interchangeable with fruit-derived Kaempferol 98% |
Sophora Japonica Fruit Extract Powder 30% Kaempferol | Fruit-derived extract with lower Kaempferol content | Same broad plant source and marker, different concentration |
Sophora Japonica Fruit Extract Powder 98% HPLC Assay | Fruit-derived high-purity Kaempferol grade tested by HPLC | Closest match where 98% Kaempferol is required |
This comparison is especially useful when reviewing supplier quotations. A lower-priced material may look attractive at first, but it may represent a different grade. Price cannot be assessed fairly unless the specification is the same.
The cleanest approval route is to match the following details exactly:
Botanical name
Sophora japonica L.
Plant part
Fruit
Active marker
Kaempferol
Offered grade
98%
Test method
HPLC
Assay result
98.07%, or the agreed batch-specific value within specification
Supplier documentation
Specification sheet, certificate of analysis, and any other required quality records
If one of these points changes, the material deserves a fresh review.
What to request from the supplier
A high-purity ingredient should be backed by clear documentation. For Sophora Japonica Fruit Extract Powder Kaempferol 98%, buyers can request documents that confirm identity, assay, and batch quality.
Useful documents may include:
Specification sheet
Certificate of analysis
HPLC assay information
Botanical identity statement
Plant part confirmation
Batch number and manufacturing date
Shelf-life or retest information
Storage recommendations
Allergen, GMO, residual solvent, heavy metal, and microbiological information where needed
Safety data sheet for handling and transport
The exact documentation set depends on the market, application, and internal quality system. For cosmetic use, the material should also be reviewed against the relevant regulatory and safety requirements in the intended sales region.
A Clover Nutrition Inc presents this ingredient as a high-purity raw material for clean beauty and cosmetic formulation work. The company has 11 years of focus on high-purity ingredients and cosmetic ingredient raw materials, which supports buyers who need defined botanical actives rather than broad extract descriptions.
How to write the purchase specification clearly
Clear purchase wording helps prevent substitutions. A vague purchase line such as “Sophora japonica extract powder” leaves too much room for interpretation.
A stronger line would state:
Sophora Japonica Fruit Extract Powder, botanical identity Sophora japonica L., plant part fruit, Kaempferol 98% by HPLC, target assay 98.07% or batch result within agreed specification.
This wording gives the supplier and internal quality team the same reference point. It also makes it easier to compare offers from different sources.
Avoid using these terms as substitutes unless the supplier confirms they refer to the same material:
Sophora japonica raw powder
Sophora japonica ratio extract
Sophora japonica flower extract
Sophora japonica luteolin extract
Kaempferol 30%
Botanical flavonoid extract
High-purity plant extract without assay details
Some of these may be useful products, but they are not the same purchasing item.
Formulation considerations for clean beauty use
Clean beauty development often favours botanical ingredients with a clear story and traceable quality profile. Still, romance should not replace specification control. A plant-derived material must be evaluated the same way as any other cosmetic raw material.
For Sophora Japonica Fruit Extract Powder Kaempferol 98%, formulation teams should review:
Solubility in the intended system
Colour impact in the finished product
Odour profile
Stability under processing conditions
Compatibility with other actives
pH range of the finished formula
Recommended use level from technical documentation
Regional cosmetic compliance
Safety assessment requirements
No botanical powder should be added to a cosmetic formula only because it sounds natural or premium. The technical fit matters. A high-purity powder may need pre-dispersion, careful mixing, or compatibility testing before scale-up.

Quality questions to settle before final approval
Before approving Sophora Japonica Fruit Extract Powder Kaempferol 98%, make the review practical. The best questions are direct and document-based.
Ask whether the offered batch matches Sophora japonica L. fruit. Confirm that Kaempferol is the target marker and that the offered grade is 98% by HPLC. Check the reported assay result and compare it with the agreed specification.
Next, compare the proposed material against any similar grade already in the purchasing system. If the company has previously used a 30% Kaempferol extract, update the records so the 98% grade is not treated as a simple replacement. If a luteolin flower extract is already approved, keep it separate in the raw material library.
Good internal naming helps. A raw material database entry should include the plant part and marker level in the name, not only the species. That reduces the chance of warehouse, sampling, or purchasing errors later.
The takeaway for buyers and formulators
Sophora Japonica Fruit Extract Powder Kaempferol 98% is best handled as a precise, high-purity botanical ingredient specification. The defining points are clear: Sophora japonica L., fruit, Kaempferol 98% by HPLC, with a stated result of 98.07%.
Do not approve it as a generic Sophora japonica extract. Do not swap it with flower extract 95% luteolin, fruit extract 30% Kaempferol, raw powder, or a ratio extract without a full review.
