Description

Bupleurotoxin is a bioactive natural product and a key chemical marker derived from the roots of *Bupleurum* species, a genus of plants widely used in traditional medicine. This compound is of significant interest for its role in quality control and pharmacological research related to herbal extracts and phytopharmaceuticals. It serves as an essential reference standard for analytical laboratories, research institutions, and manufacturers in the pharmaceutical, nutraceutical, and botanical extract industries.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and quality control of *Bupleurum*-based herbal medicines and finished products.
• Analytical Research: Serves as a critical standard in method development and validation for analytical techniques such as HPLC, LC-MS, and TLC in phytochemical analysis.
• Bioactivity Studies: Employed in pharmacological and biochemical research to investigate potential biological activities, mechanisms of action, and structure-activity relationships.
• Nutraceutical & Dietary Supplement Manufacturing: Used to standardize and authenticate botanical extracts, ensuring product consistency, potency, and label claim verification.
• Academic & Institutional Research: A vital tool for universities and research centers studying natural product chemistry, pharmacognosy, and traditional medicine modernization.

Quality Control

Our Bupleurotoxin is produced and handled under strict quality management protocols to ensure the highest standards of purity and identity for research and analytical use. Each batch is characterized using advanced spectroscopic and chromatographic methods, including NMR, MS, and HPLC. A comprehensive Certificate of Analysis (COA) detailing purity, identification tests, and chromatographic data is provided with every shipment to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). For long-term stability, consider storage at 2-8°C. The container should be kept in a desiccated environment to prevent moisture uptake.
