Key Application Fields
FAQ ：Ginkgo Biloba Extract
Q: What are the core active components of your Ginkgo Biloba Extract?
A: The core active components are total flavonoid glycosides and total terpenoid lactones. We adopt the internationally recognized "24/6" gold standard ratio, i.e., total flavonoid glycosides ≥24% (calculated as quercetin, kaempferol, and isorhamnetin glycosides) and total terpenoid lactones ≥6% (including ginkgolides A, B, C and bilobalide). We also provide customizable specifications (10%-98% active ingredients) to meet different formulation needs.
Q: How do you control ginkgolic acid content, and what is the safety limit?
A: Ginkgolic acid is a potential sensitizing substance, so we strictly remove it throughout the production process. The safety limit is controlled to ≤5 ppm, which complies with global pharmacopoeial standards and ensures product safety for end-use applications.
Q: How do you ensure batch-to-batch consistency of the extract?
A: We establish a full-chain traceable quality control system. Raw materials are sourced from GAP-certified Ginkgo biloba plantations, and advanced extraction technologies (water extraction, alcohol extraction, column chromatography) are adopted. Each batch undergoes strict quality testing before delivery, and we provide a Certificate of Analysis (COA) to ensure consistent quality across batches.
Q: What industries is your Ginkgo Biloba Extract suitable for?
A: It is widely used in dietary supplements, pharmaceuticals, food & beverages, and cosmetics. Specifically, it is applied in cognitive health supplements, cardiovascular support formulations, eye health products, and anti-aging skincare, catering to the functional needs of different end products.
Q: Do you provide samples for testing?
A: Yes. We offer small trial samples for customers to conduct quality and formulation testing. The sample specifications are consistent with bulk orders to ensure the reliability of your test results.
