Osthole synthesis

10synthesis methods

Osthole is a class of natural coumarin compound which had been initially extracted from Umbelliferae plants. The dried ripe fruit of Fructus Cnidii in the Umbelliferae plant, Cnidium monnieri has a relative high content, hence obtaining the name. Related research has shown that Osthole is also presented in other kinds of plants, including Umbelliferae including Angelica, Archangelica Hoffm and Cnidium as well as rutaceous plant such as citrus, clausena, Limonia acidissima and Haplophyllum A. Juss.
