Progress in the Study of Chemical Structure and Pharmacological Effects of Total Paeony Glycosides Isolated from <i>Radix Paeoniae Rubra</i>

Abstract

Radix paeoniae rubra, known as red peony root, is derived from the dried roots of Paeonia lactiflora pall or Paeonia veitchii lynch from the Ranunculaceae family. It is recognized for its properties of clearing heat, cooling blood, dispelling stasis, and alleviating pain, making it one of the most commonly used herbs in traditional Chinese medicine. Total paeony glycosides (TPGs) are identified as the principal active constituents of Radix paeoniae rubra, comprising monoterpenoid compounds with a cage-like pinane structure and monoterpenoids with a lactone structure. This review summarizes the chemical constituents and pharmacological effects of TPGs, with the aim of elucidating their relationships.
