1. Neo-​clerodane diterpenoids from Scutellaria orientalis subsp. pinnatifida
Quick View  Other Sources
By Malakov, Peter Y.; Papanov, Georgi Y.
From Phytochemistry (1996), 43(1), 173-178.  |  Language: English, Database: CAPLUS
Three new neo-​clerodane derivs., scutorientalins A-​C, have been isolated from an acetone ext. of the aerial parts of Scutellaria orientalis subsp. pinnatifida.  The structures of the new diterpenoids, (I-​III)​, were established by chem. and spectroscopic means and by comparison with closely related compds.


1. neo-​Clerodane Diterpenoids from the Aerial Part of Scutellaria barbata
Quick View  Other Sources
By Lee, Hanna; Hee Shim, Sang
From Helvetica Chimica Acta (2011), 94(4), 643-649.  |  Language: English, Database: CAPLUS
Three new neo-​clerodane diterpenoids, barbatellarines C-​E (1-​3)​, were isolated from the CHCl3-​sol. fraction of the aerial part of Scutellaria barbata.  Their chem. structures were elucidated by detailed anal. of NMR and MS data.  Compds. 1 and 2 were C(13) epimers, which was confirmed by an NOE difference expt. and the NOESY spectrum.  The relative configuration was detd. on the basis of the 1H-​NMR J-​value and NOE data, while the abs. configuration of the previously isolated analog, barbatellarine B (4)​, as a representative member of the group, was assigned by CD anal.
