Biflavanones, diterpenes, and coumarins from the roots of Stellera chamaejasme L.
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. supplie...
متن کاملA New C-3/C-3"-Biflavanone from the Roots of Stellera chamaejasme L.
A new 3, 3"-biflavanone, neochamaejasmin C (1), was isolated from the roots of Stellera chamaejasme L., together with four known compounds. Their structures and configurations were elucidated by spectroscopic methods, including 2D-NMR techniques.
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 ...
متن کاملHepatic glucuronidation of isoneochamaejasmin a from the traditional Chinese medicine Stellera chamaejasme L. Root.
Isoneochamaejasmin A (INCA), a biflavonoid, is one of main active ingredients in the dried root of Stellera chamaejasme L., a widely used traditional Chinese medicine. In the present study, we identified the glucuronidation metabolite of INCA and characterized the UDP glucuronosyltransferases (UGTs) responsible for INCA glucuronidation. 7-O-glucuronide (M1) and 4'-O-glucuronide (M2) were identi...
متن کاملA new dicoumarinyl ether from the roots of Stellera chamaejasme L.
A new dicoumarinyl ether, 3-hydroxy-6-methoxy-7,7'-dicoumarinyl ether (1), was isolated from the roots of Stellera chamaejasme L, together with the known compound umbelliferone (2). Their structures were determined on the basis of spectroscopic techniques, including IR, NMR, and HR-ESI-MS.
