Overview
Quisqualis Indica Extract Powder is a concentrated form of bioactive compounds derived from the fruit of Quisqualis indica, a climbing shrub native to Southeast Asia. Traditionally used in Chinese and Ayurvedic medicine, this extract is valued for its anthelmintic (parasite-expelling) properties. Modern applications extend to pharmaceuticals and nutraceuticals, where it serves as a natural alternative to synthetic anthelmintics. The extraction process typically involves ethanol or water-based methods to preserve thermolabile compounds like quercetin and tannins. As a B2B product, it is commonly available in bulk quantities with varying purity levels (10:1 to 20:1 concentrates), catering to formulation needs in capsule, tablet, or liquid dosage forms.
Physical and Chemical Properties
The powder exhibits hygroscopic tendencies, requiring careful moisture control during storage. Its characteristic bitter taste and faint herbal aroma are attributed to terpenoids and alkaloids present in the source material. Analytical profiles typically show 2-5% total flavonoids (as quercetin equivalents) and 1-3% tannins, though these values vary by extraction methodology. Key stability challenges include sensitivity to UV light and oxidation. Most commercial grades incorporate silica gel desiccants in packaging to extend shelf life. When tested for flowability, the powder generally falls within the 'fair' category (Hausner ratio ~1.3), often necessitating glidants for automated capsule filling processes.
Main Applications
In human medicine, the extract is formulated into intestinal parasite treatments, often combined with other botanicals like pumpkin seed extract. Recent research explores its potential as an immune modulator in veterinary applications, particularly for poultry and livestock worm control where chemical residue concerns exist. The nutraceutical industry utilizes it in digestive health supplements, frequently marketed as 'natural cleanse' products. Some cosmetic manufacturers incorporate low concentrations (<1%) into anti-inflammatory skincare formulations, capitalizing on its flavonoid content. Emerging applications include aquaculture feed additives to reduce nematode infections in farmed fish.
Safety and Storage
While classified as generally recognized as safe (GRAS) in appropriate doses, overdose may lead to gastrointestinal discomfort. Industry safety protocols recommend personal protective equipment (PPE) during handling to prevent respiratory irritation from fine particles. Optimal storage requires double-layer aluminum foil bags with oxygen absorbers, maintaining relative humidity below 45%. Under these conditions, the powder maintains 90%+ potency for 24 months. Refrigeration (4°C) is advised for long-term storage of high-value pharmaceutical-grade material. Batch testing for aflatoxins and heavy metals is essential, especially for export markets with stringent regulatory requirements.
B2B Procurement Guide
Reputable suppliers should provide Certificate of Analysis (CoA) documents specifying active compound concentrations, pesticide residues, and microbial limits. For pharmaceutical applications, look for GMP-certified producers capable of supplying DMF (Drug Master File) documentation. Sample evaluation should include solubility tests in your intended solvent system and accelerated stability studies (40°C/75% RH for 3 months). Price negotiation typically improves at 100kg+ quantities, though MOQs vary by supplier. Consider toll processing options if requiring custom extract ratios or excipient blends. Payment terms for new vendors often start at 30% advance with LC (Letter of Credit) arrangements common for international transactions.
