Tenuifoliside D3

Updated: 2026-07-22

Overview

Polygalasaponin D3 is a triterpenoid saponin extracted from the roots of Polygala tenuifolia, a herb widely used in traditional Chinese medicine. It is one of the key bioactive components responsible for the herb's therapeutic effects, particularly in supporting cognitive function and neurological health. Research has shown that Polygalasaponin D3 can cross the blood-brain barrier, making it effective in neuroprotection and memory enhancement. Its use in modern medicine is expanding, with studies exploring its potential in treating neurodegenerative diseases like Alzheimer's.

Physical and Chemical Properties

Polygalasaponin D3 is a white to off-white crystalline powder with a molecular weight of 1221.38 g/mol. It is highly soluble in water and methanol, which facilitates its incorporation into various pharmaceutical formulations. The compound is stable under normal storage conditions but may degrade when exposed to excessive heat, light, or moisture. Its solubility profile and stability are critical factors for formulators developing oral or injectable products containing this active ingredient.

Main Applications

The primary application of Polygalasaponin D3 is in the pharmaceutical and nutraceutical industries, where it is used as an active ingredient in cognitive-enhancing supplements and neuroprotective drugs. In traditional Chinese medicine, it is valued for its ability to calm the mind and improve memory. Modern formulations often combine it with other nootropics or herbal extracts to create synergistic effects for brain health products.

Safety and Storage

Polygalasaponin D3 is considered safe for use in approved applications, with no significant toxicity reported at therapeutic doses. However, standard laboratory precautions should be followed when handling the pure compound. Proper storage is essential to maintain its efficacy. The powder should be kept in airtight containers, protected from light and moisture, at temperatures below 25°C. Long-term stability is best ensured by storing it in a desiccated environment.

B2B Procurement Guide

When sourcing Polygalasaponin D3, B2B buyers should prioritize suppliers with verified quality control processes and transparent sourcing practices. Key considerations include the purity level (typically ≥98% by HPLC), absence of heavy metals, and microbiological safety. Buyers should request certificates of analysis (CoA) for each batch and consider suppliers who can provide documentation of Good Manufacturing Practices (GMP) compliance. Pricing varies based on purity, quantity, and supplier reputation, with bulk purchases often attracting discounts.
