Oleanlic Acid and Ursonic Acid Analysis of Chaenomelis Fructus by LC-UV


Chaenomeles, the fruit of the Chinese flowering quince, is utilized in Traditional Chinese Medicine (TCM) for its analgesic, anti-inflammatory, antispasmodic and astringent properties, and has also been shown to aid in digestion. For implementation of quality control processes, Chinese Pharmacopoeia has released the assay of oleanolic acid and ursonic acid of the herbal plant. In this work, the analysis of these two compounds, following Chinese Pharmacopoeia 2020 standards, is presented utilizing a PerkinElmer LC 300 system with SimplicityChrom software, PerkinElmer Epic C18 column and additional chromatography consumables.
