Products Description

Kudzu root extract. Kudzu root powder is a premium botanical ingredient widely recognized in the health and wellness industry for its powerful phytoestrogen properties, supporting women's health, cardiovascular health, and antioxidant defense. "The extract is obtained from the root of Pueraria lobata (wild kudzu) and is standardized to be rich in puerarin, the most significant bioactive isoflavone in the root. Known for its potential benefits in improving blood circulation, balancing hormones and protecting nerve function, puerarin has become a popular choice in supplement, functional food and skin care formulations.
As global demand for natural plant hormone support ingredients continues to grow, especially in markets such as Southeast Asia, Europe and North America, high-purity puerarin extracts are becoming increasingly popular among nutraceutical brands and OEM formulators. However, sourcing consistent, standardized, highly bioavailable extracts remains a challenge.
At Botanical Cube, we offer custom specifications of puerarin powders ranging from 10% to 98% purity, using advanced HPLC detection and cryogenic extraction technology to maximize the retention of active ingredients. We also support customers with small batch customization, allowing them to more easily formulate high-performance products that meet clean label requirements.

Why choose our Pueraria extract (Purarin powder)?

1. High purity, HPLC verified, purity ≥98%
We provide Puerarin with HPLC confirmed purity ≥98%. Our batch-to-batch variation is kept within ±1%, ensuring consistent efficacy, especially suitable for formulations that require stability in functional foods or supplements.
2. Non-GMO and solvent-free extraction
We use an ethanol-water extraction method that does not contain any toxic residues (no chloroform or ethyl acetate), making our products safer for pharmaceutical and cosmetic applications.
3. Shelf life stability testing
We conducted accelerated stability testing (40°C / 75% RH for 6 months), and the results showed that the degradation rate of Puerarin content was less than 2%, which means that our products can maintain their efficacy during long-distance transportation and storage.
