Three New Phenolic Compounds from the Roots of Sophora leachiana.

By further investigation of the root constituents of Sophora leachiana, eight phenolic compounds, including two new flavanones 1 and 2 and a new chromone 3, were isolated. The structures were established by means of spectroscopic analysis

New Neolignan and Phenylpropanoid Glycosides in Juniperus communis var. depressa

Two new neolignan glucosides (junipercomnosides C and D) and two new phenypropanoid glycosides (junipercomnosides E and F) were isolated from aerial parts of Juniperus communis var. depressa along with seven known phenylpropanoid glycosides. The structures of the isolated compounds were determined by spectral analysis, in particular by the detailed analysis of 2D NMR and CD spectra.

New glycosides of acetophenone derivatives and phenylpropanoids from Juniperus occidentalis

New glycosides of seven acetophenone derivatives (1–7) and two phenylpropanoids (8, 9), named juniperosides III–XI, have been isolated from the MeOH extract of the leaves and stems of Juniperus occidentalis Hook. (Cupressaceae), together with eleven other known compounds. The structures of these compounds have been successfully elucidated using a variety of spectroscopic techniques.
