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. ~5 |
