Chemistry and Biological Activities
Over 262 compounds have been obtained so far from the plants of Paeoniaceae. These include monoterpenoid glucosides, flavonoids, tannins, stilbenoids, triterpenoids and steroids, paeonols, and phenols.
Biological activities include antioxidant, antitumor, antipathogenic, immune-system-modulation activities, cardiovascular-system-protective activities and central-nervous-system activities.
The herb known as Paeonia (Bai Shao, Radix Paeoniae Lactiflorae), in particular the root of Paeonia lactiflora has been used frequently in traditional medicines of Korea, China and Japan. Research suggests that constituents in Paeonia lactiflora - paeoniflorin and paeonol - can modulate IgE-induced scratching behaviors and mast cell degranulation.

Famous quotes containing the words chemistry, biological and/or activities:
“If thought makes free, so does the moral sentiment. The mixtures of spiritual chemistry refuse to be analyzed.”
—Ralph Waldo Emerson (1803–1882)
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
“Both gossip and joking are intrinsically valuable activities. Both are essentially social activities that strengthen interpersonal bonds—we do not tell jokes and gossip to ourselves. As popular activities that evade social restrictions, they often refer to topics that are inaccessible to serious public discussion. Gossip and joking often appear together: when we gossip we usually tell jokes and when we are joking we often gossip as well.”
—Aaron Ben-Ze’Ev, Israeli philosopher. “The Vindication of Gossip,” Good Gossip, University Press of Kansas (1994)
