Chemical constituents from Ferula sinkiangensis and their chemotaxonomic significance

Abstract

Phytochemical study of Ferula sinkiangensis led to the isolations of eleven compounds, including a new compound (2) and ten known compounds (1 and 3–11), which consisted of three sesquiterpenes (1 and 3-4), two sesquiterpene coumarins (5–6), and five sesquiterpene phenylpropanoid derivatives (7–11). The 13C NMR data, relative configuration and optical rotation of compound 1 were reported for the first time. Compounds 1 and 5–11 were reported for the first time from Ferula sinkiangensis, and they were found only in the genus Ferula. Herein, we discussed the chemotaxonomic significance of the isolated compounds.
