Overview
Picrasidine is a bioactive quassinoid compound extracted from Picrasma quassioides, a tree native to East Asia. It is traditionally used in Chinese herbal medicine for its antipyretic and detoxifying effects. Modern research highlights its potential as an anticancer and anti-inflammatory agent, driving interest in pharmaceutical applications. Chemically, it belongs to the terpenoid family and is structurally similar to other quassinoids like bruceine. Its bitter taste and low water solubility are characteristic of this class. Current studies focus on isolating its active isomers and optimizing extraction methods for industrial-scale production.
Physical and Chemical Properties
Picrasidine typically presents as a white crystalline powder with a melting point range that varies by isomer. Its solubility profile favors polar organic solvents, making ethanol a common medium for extraction. The compound is stable under dry conditions but may degrade when exposed to prolonged humidity or UV light. Spectroscopic methods (e.g., NMR, MS) are used to confirm its structure, which includes multiple oxygenated functional groups contributing to its bioactivity. Analytical standards for picrasidine are limited, requiring customized protocols for purity assessment in B2B transactions.
Main Applications
In traditional medicine, picrasidine is valued for treating fevers, dysentery, and parasitic infections. Contemporary research explores its mechanisms in apoptosis induction and NF-κB pathway inhibition, suggesting utility in oncology. It is also studied for antimicrobial effects against drug-resistant pathogens. Pharmaceutical companies investigate its derivatives to enhance bioavailability. Pilot-scale trials are underway, though clinical applications remain experimental. Herbal supplement manufacturers occasionally include trace amounts in formulations, pending regulatory approvals.
Safety and Storage
Picrasidine exhibits toxicity at high doses, necessitating controlled handling in lab or industrial settings. Personal protective equipment (PPE) such as nitrile gloves and goggles is mandatory. Acute exposure may cause gastrointestinal distress or dermatitis. Storage requires airtight containers with desiccants, ideally at 2–8°C for long-term stability. Transport under ambient conditions is acceptable for small quantities, but bulk shipments may require temperature-controlled logistics to prevent degradation.
B2B Procurement Guide
Buyers should prioritize suppliers who provide third-party purity verification (e.g., ≥98% by HPLC). Batch-specific COAs are essential, as adulteration with related quassinoids is common. Pricing correlates with purity; research-grade quantities (1–10g) often command premiums. Lead times vary due to limited commercial availability. MOQs (Minimum Order Quantities) typically start at 5g. Consider pre-shipment samples for large orders. Regional regulations may restrict import/export, so confirm compliance with local agencies like the FDA or EMA.
