Import 5-Htp Griffonia Seed Extract — Buy in Bulk from Supplier in China

Naturalin Bio Resources Co.,Ltd offers a 98% 5-HTP Griffonia Seed Extract, a single high-purity grade positioned at the upper end of the standardised range. The material is derived from Griffonia simplicifolia seed and assayed by HPLC, a method that separates 5-hydroxytryptophan from structurally similar indole alkaloids and potential synthetic analogues. At 98% concentration, this extract requires minimal excipient addition and suits applications where label claim accuracy and low variability between batches are essential.

The extraction process described involves advanced techniques, though the specific solvent system, whether supercritical CO2, ethanol-water reflux or another approach, is not detailed. Standard practice for 98% material typically includes multiple recrystallisation steps and possible preparative chromatography to remove tryptophan, serotonin and melanin-related pigments native to the seed coat. Buyers should request the full impurity profile, including specified unidentified impurities and total impurities, as these parameters distinguish pharmaceutical-grade from nutraceutical-grade material even at comparable assay values.

This extract is targeted at dietary supplement manufacturers, wellness brand owners and contract formulators developing mood and sleep support products. The supplier indicates bulk supply options and flexible trade benefits, suggesting capacity for both tonne-scale and smaller pilot batches. Prospective buyers should confirm actual stock levels, retest date or shelf life under recommended storage, and whether Naturalin provides regulatory support documents such as master files or stability data for new product licence applications.

Naturalin Bio Resources Co.,Ltd is headquartered at Lu-Valley Enterprise Square, No.27 Wenxu, Changsha, Hunan Province, 411000, China. Changsha sits within a major Chinese biotechnology and plant extract manufacturing postcode, with access to research institutions and raw material markets. The supplier holds an imported tier classification alongside harbor trust status, suggesting some cross-border trade experience, though the 0.00 percent response rate indicates no recent inquiry activity is recorded.

The listing profile does not state year of establishment, production floor space, number of employees, annual turnover, named domestic or international clients, or specific quality certifications held. Buyers should therefore request a company profile, manufacturing licence and any third-party audit reports directly. The address places Naturalin in a recognised industrial zone, which can facilitate customs verification and on-site inspection logistics for larger contractual agreements.
