Corosolic acid 18% cas 4547-24-4
product introduction
18% Corosolic acid is a standardized, enriched monomer powder, distinct from conventional *Lagerstroemia speciosa* (Banaba) extracts. While standard extracts consist of a mixture of all leaf components—including significant amounts of tannins and polyphenols—this product undergoes chromatographic enrichment and purification to specifically boost the corosolic acid monomer content (CAS: 4547-24-4; a pentacyclic ursane-type triterpene) to 18%. Quantified via HPLC, it offers consistent active ingredient purity and minimal batch-to-batch variation, making it ideal for precision formulation development.
This product is a fine powder ranging from light yellow to pale brown; slight characteristic botanical odor.
product benefits
Disclaimer: Statements have not been evaluated by FDA. This ingredient is not intended to diagnose, treat, cure or prevent any disease. For dietary supplement formulation only.
1. Supports healthy glucose metabolism. Corosolic acid promotes GLUT4 translocation on cell membrane, accelerating glucose uptake in muscle and adipose tissue, helping maintain normal postprandial blood glucose level.
2. Inhibits alpha-glucosidase activity, slows carbohydrate hydrolysis, reduces blood sugar spike after meals.
3. Antioxidant & anti-inflammatory activity, helps relieve chronic low-grade inflammation related to metabolic imbalance.
4. Supports healthy lipid profile, assists with metabolic syndrome formulation design.
5. Formulation advantage vs crude Banaba extract: Purified 18% monomer fraction reduces tannin interference, less bitter taste, better compatibility with capsule, tablet and softgel delivery systems; consistent active content, easier dosage calculation for R&D teams.
product application
Blood Sugar Support Supplements
Glycemic management supplements are a mature global category where brands differentiate on clinical-grade actives and accurate labeling rather than raw herb powders.
Corosolic acid 18% is tableted or encapsulated, typically paired with chromium picolinate, cinnamon, or fenugreek; the water-insoluble powder handles well with standard excipients.
Weight Management & Metabolic Formulas
Consumers managing weight look for ingredients that support carbohydrate utilization and metabolic rate alongside diet and exercise.
Blends of the extract with green coffee and L-carnitine suit capsule and stick-pack formats.
Sports Nutrition & Energy Products
Glucose-utilization ingredients are entering pre-workout and intra-workout nutrition as athletes seek better nutrient partitioning.
Corosolic acid powder disperses in flavored drink premixes, with masking flavors covering the mild herbal note.
Functional Teas & Traditional-Style Products
Banaba has a centuries-old use as a leaf tea in the Philippines, giving functional beverage brands an authentic heritage angle.
Solubilized or encapsulated banaba extract formats, plus dried granule sachets, carry the tea tradition into modern stick-packs.
customer case
Case 1: North America dietary supplement brand
Customer requirement: Launch blood sugar support capsule, strict active content consistency requirement. Previously used ordinary banaba leaf crude extract, facing unstable HPLC reading and high tannin content. Switched to our 18% Corosolic Acid monomer powder. We supplied 300kg bulk order, provided full COA + heavy metal report. Final product passed US third-party finished product testing.
Case 2: European contract manufacturer
Customer developed metabolic health multi-ingredient tablet. Need low tannin botanical raw material to avoid tablet discoloration. Our 18% corosolic acid monomer powder reduced color interference, passed EU heavy metal and pesticide residue audit, recurring quarterly bulk purchase.

Q:What is the difference between corosolic acid and ursolic acid?
A:Corosolic acid and ursolic acid are positional isomers, meaning they share the same molecular formula C30H48O4 but differ in hydroxyl group position. Corosolic acid dominates in banaba leaves, while ursolic acid is common in rosemary, apple peel, and other botanicals. HPLC methods separate and quantify each compound accurately.
Q:How does corosolic acid support healthy blood sugar?
A:Research indicates corosolic acid promotes GLUT4 translocation to the cell membrane, increasing glucose uptake in muscle and fat tissue. It may also inhibit alpha-glucosidase, slowing carbohydrate digestion. These mechanisms help maintain already-healthy blood glucose levels, which is why the compound is popular in metabolic wellness supplements.
Q:How do you verify corosolic acid 18% specification?
A:Each batch is assayed by HPLC against a reference standard of the pure compound. Certificate of analysis values include assay, loss on drying, heavy metals, residual solvents, and microbial counts. Stability studies confirm the extract maintains at least 95 percent of labeled corosolic acid content through twenty-four months.
Q:Can this ingredient be used for softgel formulation?
A:Yes, low tannin feature reduces discoloration risk, compatible for softgel, capsule and tablet formulations.
