Description
5-Hydroxytryptophan (5-HTP) is a natural ingredient extracted from the seeds of the West African plant Griffonia simplicifolia. The product is a brown, odorless powder with a slightly salty taste. It is standardized for 5-HTP content at various concentrations: 20%, 40%, 60%, and 98%. 5-HTP is soluble in hot alcohol, dilute alkaline solutions, and dilute hydrochloric acid, sparingly soluble in water, and insoluble in chloroform. Testing is performed using HPLC, ensuring accurate determination of the active compound. For purchasers, the specification of 5-HTP concentration is crucial, as it dictates its application and dosage in final products. The product has a shelf life of 24 months.
