Banaba Dry Extract is a botanical ingredient prepared from the dried leaves of Lagerstroemia speciosa (L.) Pers., a member of the Lythraceae family. The plant is commonly known as Banaba and is also associated with regional names such as Jarul and Tamhan in India.
Commercial Banaba Leaf Extract is available in different grades, with corosolic acid commonly used as a standardization marker. Extract characteristics depend on the botanical raw material, extraction process, concentration method and finished-product specification. Buyers should confirm the marker percentage and analytical method for the exact grade they intend to purchase.
The botanical name for Banaba is Lagerstroemia speciosa (L.) Pers. The plant belongs to the Lythraceae family, and dried leaves are the specified plant part for Banaba Leaf Dry Extract.
Correct plant-part identification is important because a leaf extract is not interchangeable with extracts or materials derived from other plant parts. The botanical name, plant part and product grade should be stated in the manufacturer's technical documentation and supported by appropriate identification and traceability procedures.
Banaba Dry Extract is generally produced by extracting identified dried leaves with a suitable solvent, separating insoluble plant material, concentrating the extract and drying it into a powder. Hydroalcoholic extraction is used in the USP definition of Banaba Leaf Dry Extract, although commercial methods can differ by grade.
The extraction solvent, native extract ratio and any added carriers should be documented. Ratios such as 10:1 or 20:1 and assay values such as 1% or 2% corosolic acid are examples of commercial grades, not universal requirements for every Banaba extract.
Corosolic acid is a triterpenoid constituent used as a quantitative marker for standardized Banaba leaf extracts. Commercial products may be offered with different labelled concentrations, and the analytical method should be clearly specified. HPLC is used in commercial specifications to measure corosolic acid.
The actual assay value must be verified from the current certificate of analysis (COA). Corosolic acid as an isolated compound should not be confused with the complete botanical extract: the marker's chemical formula and CAS number do not identify the full multi-component extract.
Quality control for Banaba Dry Extract may include botanical identification, appearance, moisture or loss on drying, ash, particle size, bulk density, assay, residual solvents, heavy metals and microbiological quality. The exact parameters and acceptance limits depend on the commercial grade and applicable specification.
The USP monograph provides a defined identity and labelled corosolic-acid assay framework for Banaba Leaf Dry Extract. Other supplier specifications may use different moisture, ash, particle-size and contaminant limits. Buyers should use the approved specification for the grade being purchased rather than combining limits from different sources.
Banaba Leaf Extract is a botanical ingredient used in commercial botanical and formulation supply chains. Its suitability for a particular food, wellness, cosmetic or other application must be assessed separately from its botanical identity. Product descriptions should not imply that a particular grade is approved for every use.
Before procurement, confirm the plant part, extraction solvent, standardization, intended-use requirements and relevant safety documentation. Any regulatory or quality claim should be supported by the applicable documentation for the actual product.
Banaba Dry Extract should be packed in suitable sealed packaging that protects the material from moisture and contamination. Storage conditions, packaging type, shelf life and retest period should follow the manufacturer's approved technical data sheet and supporting stability documentation.
For bulk procurement, buyers should confirm available pack sizes, minimum order quantity, batch traceability and delivery terms directly with the supplier.
Buyers evaluating Banaba Dry Extract should request the current COA, technical data sheet (TDS), botanical identification, confirmation of dried leaves as the plant part, extraction solvent, extract ratio and corosolic-acid assay where applicable. Relevant residual-solvent, contaminant and microbiological test results should also be reviewed.
Accurate documentation allows buyers to compare grades and verify batch consistency. Product descriptions should reflect the material actually supplied, and all assay, certification, manufacturing and supply claims should be traceable to approved records.
