从China供应商批量进口5-Hydroxytryptophan

5-hydroxytryptophan (5-HTP, C11H12N2O3) is a naturally occurring amino acid derivative extracted from the seeds of Griffonia simplicifolia, supplied by Shaanxi Sciphar Biotechnology Co., Ltd. from Xi'an, Shaanxi Province, China. The compound functions as a direct metabolic precursor to serotonin, bypassing the rate-limiting tryptophan hydroxylase step. The supplier's source material specifies a purity of 98% or higher, though buyers should verify whether this figure represents HPLC assay or titration, and request batch-specific certificates of analysis. Available formats include capsule and powder forms, with the latter being more common for bulk nutraceutical manufacturing and private-label formulation.

Griffonia simplicifolia seed extract standardisation typically centres on 5-HTP content, with reputable suppliers controlling for peak X (a related compound associated with eosinophilia-myalgia syndrome risk), residual solvents from extraction, and microbial limits. The powder form suitable for tablet compression or capsule filling typically requires particle size control, flowability, and moisture specification below a defined threshold. Shaanxi Sciphar Biotechnology's listing mentions ISO and SGS certification without specifying scope or certificate numbers, so importers should request documentary evidence. The compound's stability is pH and light dependent, with standard storage in tightly closed containers protected from moisture and direct sunlight.

The primary import market for this material comprises dietary supplement manufacturers, contract packagers, and health product distributors serving formulations targeting mood support, sleep regulation, and appetite management. Bulk powder 5-HTP is also used in functional food development and clinical research supply. The supplier indicates flexible MOQ and FOB or CIF shipping terms, though exact quantities and port details are not stated. Buyers should negotiate specification sheets, confirm extract ratio or pure isolate status, and determine whether the supplier offers granular or micronised variants to match their formulation equipment requirements.

Shaanxi Sciphar Biotechnology Co., Ltd. is headquartered at No.11, Tangxing Road, Xi'an, 710075, Shaanxi Province, China. The company operates within the Xi'an biotechnology cluster, a region known for botanical extraction, traditional Chinese medicine modernisation, and nutraceutical ingredient production. The supplier holds an imported tier and harbor trust tier on the platform, with a 0.00% response rate and zero average response hours recorded. This communication profile indicates that platform-mediated messaging may not be monitored actively, so direct outreach to the company's business development or export department is advisable for reliable engagement.

The listing does not provide the company's founding date, number of employees, annual turnover, factory floor space, or specific ISO standards to which they are certified. No client list, export destinations, or R and D capabilities are disclosed. The mention of SGS certification lacks a certificate number or scope description, so buyers must request verification documents. For importers evaluating supplier capability, it is worth asking about in-house extraction capacity versus toll processing, quality control laboratory accreditation, and whether the company holds export licences for botanical APIs or dietary supplement ingredients. A facility audit, even remote, would help confirm GMP-adjacent operating conditions.
