Description

Ciwujianoside E CAS NO 114912-36-6 is a bioactive saponin compound primarily isolated from *Eleutherococcus senticosus* (Siberian ginseng). This high-purity reference standard is critical for analytical research, quality control, and the development of standardized herbal extracts. It is essential for manufacturers and research institutions in the nutraceutical, pharmaceutical, and botanical extract industries requiring precise quantification and biological activity studies.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification and quantification of active components in Siberian ginseng extracts and finished products.
• Nutraceutical Quality Control: Serves as a key marker compound for the standardization and potency verification of dietary supplements containing *Eleutherococcus senticosus*.
• Biomedical Research: Employed in *in vitro* and *in vivo* studies to investigate its pharmacological properties, including potential adaptogenic, neuroprotective, and anti-fatigue effects.
• Herbal Extract Manufacturing: Acts as a target compound for process optimization and quality assurance during the extraction and purification of Siberian ginseng.
• Analytical Method Development: Utilized to develop and validate analytical methods such as HPLC, UPLC, and LC-MS for complex botanical matrices.
