A new 1β-hydroxy-ent-kauren diterpenoid, enanderianin C1, has been isolated from the leaves of Isodon enanderianus, and its structure has been elucidated by spectroscopic evidences.
A new flavone glycoside, 5,8-dihydroxy-4',6,7-trimethoxyflavone 8-O-(-D-glucopyranoside 1, together with three known flavonoids, pedalitin 2, cirsimartin 3 and genkwanin 4, were isolated from the aerial parts of I...A new flavone glycoside, 5,8-dihydroxy-4',6,7-trimethoxyflavone 8-O-(-D-glucopyranoside 1, together with three known flavonoids, pedalitin 2, cirsimartin 3 and genkwanin 4, were isolated from the aerial parts of Isodon enanderianus. Their structures were determined on the basis of spectral data.展开更多
A new spirosecokaurenoid, enanderinanin F 1 and its C-6 epimer, angustifolin were isolated from the aerial parts of Isodon enanderianus.

The structure of the dimer was elucidated by means of spectroscopic methods (including 2D NMR techniques). Enanderinanin J was a dimer of xerophilusin A and probably formed by cycloaddition.展开更多
