Overview
Andrographolide is a bioactive diterpenoid lactone primarily extracted from Andrographis paniculata, a herb commonly used in traditional Asian medicine. It is known for its bitter taste and potent pharmacological properties, including anti-inflammatory, antiviral, and immune-boosting effects. The compound has gained attention in modern medicine for its potential therapeutic applications, particularly in treating respiratory infections and inflammatory conditions. Research indicates that andrographolide modulates several cellular pathways, making it a promising candidate for drug development. Its mechanism of action includes inhibiting NF-κB signaling, which plays a key role in inflammation. Due to these properties, it is increasingly used in pharmaceuticals and dietary supplements.
Physical and Chemical Properties
Andrographolide is a white to off-white crystalline powder with a molecular weight of 350.45 g/mol. It has a melting point range of 230-234°C and is soluble in organic solvents like ethanol and methanol but only slightly soluble in water. The compound is stable under normal storage conditions but should be protected from light and moisture to prevent degradation. The molecular structure of andrographolide includes a lactone ring and multiple hydroxyl groups, which contribute to its bioactive properties. Its low water solubility can be a limitation in formulation, but this is often addressed using solubilization techniques or derivatives with improved bioavailability.
Main Applications
Andrographolide is primarily used in the pharmaceutical industry for its anti-inflammatory and immunomodulatory effects. It is a key ingredient in traditional remedies for colds, flu, and upper respiratory infections. Modern applications include its use in dietary supplements aimed at boosting immune function and reducing inflammation. In addition to its medicinal uses, andrographolide is studied for its potential in treating chronic diseases such as cancer and diabetes. Preclinical studies suggest it may inhibit tumor growth and improve insulin sensitivity, though further clinical research is needed to confirm these effects.
Safety and Storage
Andrographolide is generally regarded as safe when used in recommended doses. However, high doses may cause mild side effects such as stomach upset or dizziness. It is important to follow dosage guidelines, especially in supplement formulations. For storage, andrographolide should be kept in a cool, dry place, ideally in airtight containers to protect it from moisture and light. Proper handling includes wearing gloves and masks to avoid inhalation or skin contact, particularly in industrial settings.
B2B Procurement Guide
When procuring andrographolide, buyers should prioritize suppliers with verified credentials and quality certifications. Key factors to consider include purity levels (typically 98% or higher), solvent residues, and heavy metal content. Reputable suppliers often provide certificates of analysis (CoA) for each batch. Price varies based on purity and quantity, with bulk purchases generally offering cost savings. Buyers should also consider logistics, such as shipping conditions and lead times, to ensure the product arrives in optimal condition. Establishing long-term relationships with reliable suppliers can help secure consistent quality and pricing.
