About Botaniex


Banaba Extract, derived from the leaves of Lagerstroemia speciosa, is a widely used botanical ingredient in the global nutraceutical, dietary supplement, and functional food industries. Standardized primarily to corosolic acid, Banaba Extract has become an important plant-based raw material for manufacturers seeking consistent quality, reliable sourcing, and flexible specifications.

As global demand for natural and standardized botanical extracts continues to grow, Banaba Extract is increasingly utilized in formulations designed for metabolic and wellness-focused applications. For B2B buyers, understanding its applications, specifications, and quality control requirements is essential for successful product development and long-term supply stability.


What Is Banaba Extract?

Banaba Extract is produced from carefully selected Banaba leaves using controlled extraction processes such as water extraction or water/grain alcohol extraction. The resulting extract is typically standardized to a specific percentage of corosolic acid, a naturally occurring triterpenoid compound that plays a key role in the functional profile of Banaba.

From an industrial perspective, Banaba Extract is valued for:

· Botanical origin and traceability

· Availability of standardized active content

· Compatibility with various formulations

· Suitability for global B2B supply chains

The extract is commonly supplied as a fine powder with good stability and process adaptability.

Key Specifications of Banaba Leaf Extract (Corosolic Acid)

To meet different formulation and dosage requirements, Banaba Extract is available in multiple standardized specifications. Common commercial grades include:

· 1% Corosolic Acid (Water Extract)

· 2% Corosolic Acid (Water Extract)

· 3% Corosolic Acid (Water or Water/Grain Alcohol Extract)

· 6% Corosolic Acid (Water/Grain Alcohol Extract)

· 10% Corosolic Acid (Water Extract)

· 20% Corosolic Acid (Water/Grain Alcohol Extract)

· 80% Corosolic Acid (Highly Concentrated Extract)

Customized specifications can also be developed based on customer requirements, application type, and regulatory considerations.


Applications of Banaba Extract

1. Dietary Supplements

Banaba Extract is widely used in dietary supplement formulations, including capsules, tablets, and powdered blends. Its standardized active content allows formulators to achieve consistent performance across production batches, which is critical for large-scale manufacturing.

In B2B supply chains, consistent particle size, flowability, and active compound stability are key considerations for supplement manufacturers.

2. Nutraceutical and Functional Food Products

With the growth of plant-based and functional nutrition markets, Banaba Extract is increasingly incorporated into:

· Functional food powders

· Solid beverages and drink mixes

· Nutritional blends

Water-soluble grades are particularly suitable for functional beverage systems, while higher-concentration extracts are often used in compact dosage forms.

3. Botanical and Herbal Formulations

Banaba Extract is frequently included in multi-ingredient botanical formulations due to its compatibility with other plant extracts. Its standardized nature makes it suitable for compound herbal products where consistency and reproducibility are required.

4. Research and Product Development

R&D teams and formulation developers source Banaba Extract for:

· Prototype development

· Stability testing

· Ingredient compatibility studies

For these applications, detailed technical documentation and consistent quality standards are especially important.


Quality Control Key Points for Banaba Extract

For global B2B buyers, quality control is one of the most critical factors when sourcing Banaba Extract. The following aspects should be carefully evaluated.

1. Raw Material Sourcing and Traceability

High-quality Banaba Extract begins with authenticated Lagerstroemia speciosa leaf material. Reliable suppliers implement:

· Botanical identification and verification

· Controlled sourcing and harvesting

· Full traceability from raw material to finished extract

This ensures long-term batch consistency and reduces supply risk.

2. Extraction Process and Standardization

Controlled extraction methods help preserve the integrity of active compounds. Standardization to defined corosolic acid levels ensures that each batch meets agreed specifications.

Quantification of corosolic acid is typically conducted using validated analytical methods such as HPLC, ensuring accurate and reproducible results.

3. Safety and Compliance Testing

Commercial Banaba Extract intended for global markets should be tested for:

· Heavy metals

· Microbiological contamination

· Residual solvents (where applicable)

Compliance with international quality and safety standards is essential for smooth market access.

4. Stability and Shelf Life

Properly manufactured Banaba Extract demonstrates good stability when stored under recommended conditions. Protective packaging and moisture control help maintain product quality during transportation and storage.

5. Documentation and Regulatory Support

A reliable B2B supplier should provide complete technical documentation, including:

· Certificate of Analysis (COA)

· MSDS

· Technical specification sheets

· Country of origin information

These documents support regulatory compliance and facilitate product registration in different regions.


Importance of Supplier Reliability in Global B2B Supply

For manufacturers, inconsistent raw materials can lead to formulation issues, production delays, and quality risks. Partnering with a professional Banaba Extract supplier helps ensure:

· Batch-to-batch consistency

· Stable long-term supply

· Reduced formulation adjustments

· Improved production efficiency

Supplier reliability is therefore a key factor in successful product commercialization.
