Overview
Corydalis Extract is derived from the roots of Corydalis yanhusuo, a plant native to China and widely used in traditional Chinese medicine (TCM). The extract is rich in bioactive alkaloids, including tetrahydropalmatine (THP), which is known for its pain-relieving and calming effects. It has been used for centuries to treat conditions like headaches, menstrual pain, and insomnia. In modern applications, Corydalis Extract is incorporated into pharmaceutical formulations and dietary supplements. Its natural origin and therapeutic properties make it a popular choice for companies seeking plant-based active ingredients. The extract is typically available in liquid or powder form, with varying concentrations of key alkaloids.
Physical and Chemical Properties
Corydalis Extract is a complex mixture of alkaloids, flavonoids, and other phytochemicals. The primary active compound, tetrahydropalmatine (THP), is a benzylisoquinoline alkaloid responsible for its analgesic effects. The extract appears as a brown to yellowish-brown liquid or powder, depending on the formulation. It is soluble in water and alcohol, making it versatile for use in various delivery systems, including capsules, tablets, and tinctures. The density of the liquid form typically ranges from 1.0 to 1.2 g/cm³. Stability is maintained when stored in cool, dry conditions, away from direct sunlight and moisture.
Main Applications
Corydalis Extract is primarily used in the pharmaceutical and nutraceutical industries. Its analgesic properties make it a key ingredient in pain relief formulations, often as an alternative to synthetic drugs. It is also used in dietary supplements aimed at reducing stress and improving sleep quality. In traditional medicine, the extract is employed to alleviate menstrual cramps, abdominal pain, and other discomforts. Some cosmetic formulations include Corydalis Extract for its anti-inflammatory benefits, particularly in skincare products targeting redness and irritation.
Safety and Storage
Corydalis Extract is generally considered safe when used as directed, though excessive consumption may lead to drowsiness or dizziness. It is advisable to consult a healthcare provider for proper dosage, especially for individuals with pre-existing conditions or those taking other medications. Storage recommendations include keeping the extract in a cool, dry place, ideally at temperatures below 25°C (77°F). Liquid forms should be tightly sealed to prevent evaporation or contamination, while powdered extracts should be protected from moisture to maintain potency.
B2B Procurement Guide
When sourcing Corydalis Extract, B2B buyers should prioritize suppliers with certifications such as GMP (Good Manufacturing Practice) or ISO standards. Key factors to evaluate include the concentration of active alkaloids (e.g., THP), extraction method (e.g., water or ethanol extraction), and batch consistency. Pricing varies based on purity and supplier reliability, with reference prices ranging from $50 to $200 per kilogram. Buyers should request lab test reports to verify alkaloid content and ensure the product meets regulatory requirements for their intended market (e.g., FDA, EU regulations).
