Description

Petasinoside is a bioactive sesquiterpene glycoside, a key marker compound derived from plants of the *Petasites* genus, valued for its potential pharmacological properties. This high-purity standard is essential for research and development, offering a reliable reference for analytical studies and quality control in botanical extract manufacturing. It is primarily sought by the pharmaceutical, nutraceutical, and academic research sectors for applications in phytochemical analysis and the development of standardized herbal products.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity determination of petasin-related compounds in drug development and quality control laboratories.
• Botanical Extract Standardization: Serves as a key marker compound for the standardization and quality assurance of butterbur (*Petasites hybridus*) extracts and related herbal supplements.
• Biochemical Research: Employed in *in vitro* and *in vivo* studies to investigate its biological activities, including potential anti-inflammatory and spasmolytic effects.
• Analytical Method Development: Critical for developing and validating analytical methods such as HPLC, LC-MS, and TLC for the quantification of sesquiterpenes in complex matrices.
• Nutraceutical Product Development: Used in the formulation and quality control of dietary supplements to ensure consistent potency and authenticity of butterbur-based products.

Quality Control

Our Petasinoside is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and MS for structural confirmation, and residual solvent analysis. We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring traceability and compliance with relevant standards for research and development purposes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption. For long-term storage, consider storing under an inert atmosphere.
