Description

Parishin B is a bioactive phenolic glucoside compound isolated from *Gastrodia elata* (Tian Ma). This high-purity reference standard is essential for research and development in the pharmaceutical and nutraceutical sectors, providing a reliable benchmark for quality control and bioactivity studies. It is primarily sought by manufacturers and research institutions focused on neuroscience, traditional medicine modernization, and analytical method development.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and quality control of Gastrodia elata extracts and related herbal preparations.
• Neuroscience Research: Investigated for its potential neuroprotective, sedative, and anticonvulsant properties in preclinical studies.
• Nutraceutical Formulation: Serves as a key marker compound for standardizing dietary supplements and functional foods derived from Gastrodia elata.
• Analytical Chemistry: Employed as an external standard for HPLC, LC-MS, and other chromatographic methods to quantify Parishin B and related compounds in complex matrices.
• Traditional Medicine Research: Used in pharmacological studies to validate the efficacy and understand the mechanism of action of Gastrodia elata in traditional applications.
