Allgemeine Beschreibung

Withanolide A is classified under the steroidal lactone group of bioactive compounds that are majorly found in Withania somnifera (L.).

Anwendung

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Withanolide A may be used as an analytical standard for the determination of withanolide A in:
  • Mentat tablet, an Indian herbal medicine by UHPLC coupled to tandem mass spectrometry (MS/MS) operating with ESI, along with multivariate analysis.
  • Withania somnifera by ultra-high performance liquid chromatography-hybrid triple quadrupole linear ion trap mass spectrometer (UHPLC-QqQ LIT-MS) equipped with electrospray ionization (ESI) source and MRM detection, along with multivariate analysis as well as HPLC combined with diode array detector (DAD).
  • Withania coagulans by LC-QqQ-ESI-MS/MS.

Biochem./physiol. Wirkung

C28-steroidal lactone that can induce nerve development and improve nervous system function. Potential therapeutic for neurologic disorders like Alzheimer′s and Parkinson′s disease. In primary rat cortical neurons, withanolide A significantly up-regulated IDE levels, a prominent enzyme involved in degrading amyloid β protein, which may help to clear excess amyloid β protein from an Alzheimer′s-inflicted brain.

Verpackung
