Biflavanones, diterpenes, and coumarins from the roots of Stellera chamaejasme L.
نویسندگان
چکیده
A new biflavanone (1) with a C-3/C-3" linkage, a new daphnane-type diterpene (2) acylated by an unsaturated fatty acid, and a new coumarin glycoside (3), along with six lignans, two phenylpropanoids, five flavonoids, two diterpenes, and three coumarins were isolated from the roots of Stellera chamaejasme L. (Thymelaeaceae). Elucidation of these secondary metabolites of S. chamaejasme L. supplied strong chemical verification of the close taxonomic relationships among the genera Stellera, Daphne, and Wikstroemia, all of which belong to the family Thymelaeaceae.

ETHNOPHARMACOLOGICAL RELEVANCE Stellera chamaejasme L. (Thymelaeaceae) was a toxic perennial herb and widely used as pesticide and dermatological agents in China. Chamaechromone was a major component in the dried roots of Stellera chamaejasme with anti-HBV and insecticidal activity. Analysis of metabolic profile in vivo and in vitro plays a pivotal role to unravel how TCM works. And the metabol...
متن کاملStellera chamaejasme Roots as Raw Material for Pulp Production
Cellulosic pulps were prepared from Stellera chamaejasme roots using soda, soda-anthraquinone (soda-AQ), and kraft pulping processes. S. chamaejasme is composed of 73.5% holocellulose, 39.7% α-cellulose, and 17.6% lignin, similar to wheat straw and other non-wood plant materials. The ethanol–benzene extractives content of 9.2% is higher than other non-woods. The conditions used for all pulping ...
