Brahucins A and B, new triterpene lactones from Spiraea brahuica

Brahucins A (1) and B (2), the new oleanane-type triterpene lactones, have been isolated from the EtOAc-soluble fraction of Spiraea brahuica Boiss, along with betulinic acid (3), oleanolic acid (4), 3-O-(β-D-glucopyranosyl) oleanolic acid (5), vanillic acid (6) and caffeic acid (7), reported for the...

Description
Summary:Brahucins A (1) and B (2), the new oleanane-type triterpene lactones, have been isolated from the EtOAc-soluble fraction of Spiraea brahuica Boiss, along with betulinic acid (3), oleanolic acid (4), 3-O-(β-D-glucopyranosyl) oleanolic acid (5), vanillic acid (6) and caffeic acid (7), reported for the first time from this species. The structures of these compounds were elucidated by spectroscopic studies including MS, IR, 1D and 2D NMR.
