In chemical aspects, Coumarin is a member of benzopyrone family, all of which are consisting of benzene ring joined with α-pyrone ring. Benzopyrones are further classified into two categories of benzo-α-pyrone to which Coumarins belong and benzo-γ-pyrone of which flavanoids are the principal candidates. The Coumarins are of great interest due to their tremendous pharmacological properties and characteristic conjugated molecular architecture [25]. The basic structure of Coumarin is as given in Figure 2.1.

Coumarin is also known as double divinylene oxide or 1,2-benzopyrone, which has been demonstrated to be the most abundant and bioactive compounds of A. pubescentis Radix, and more than 60 coumarins of A. pubescentis Radix have been isolated and identified.[3–5] Coumarin was originally used as a spice, but later gradually used as a medicine due to the anti-inflammatory, anti-bacterial, anti-oxidation, anti-tumor, anti-human immunodeficiency virus, anti-hypertension, anti-arrhythmia, anti-bone marrow osteoporosis, analgesic, and photosensitive effects.[6–15] According to published reports, osthol, columbianadin, and isoimperatorin are the primary medicinal bioactive components and have been used as the indicators for the quality control of A. pubescentis Radix.
