Abstract

Armatenols A–C (1–3), new isoflavan-4-ols, have been isolated from the CHCl3-soluble sub-fraction of Colutea armata Hemsl. & Lace, along with two known compounds namely 8-methoxyvestitol (4) and colutequinone (5), reported for the first time from this species. Their structures have been elucidated through spectroscopic techniques including MS, IR, UV, CD, 1 D and 2 D NMR. Compounds 1–2 invariably showed significant antioxidant activity using the methods of 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity (DPPH), Fe3+ reducing antioxidant power (FRAP) assay and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonate) radical scavenging activity (ABTS).

Abstract

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. [ABSTRACT FROM AUTHOR]
