“…2,9 In the present investigation, an EtOAc extract from a MeOH extract of the stem bark of C. ovata was found to be effective in scavenging ONOO − . Subsequent fractionation was conducted using the EtOAc extract, leading to the isolation of 10 new glycosides, 6,10-O-di-trans-feruloyl catalpol (1), 6,6′-O-di-transferuloyl catalpol (2), 3,4-dihydro-6-O-di-trans-feruloyl catalpol (10), (8R,7′S,8′R)-lariciresinol 9′-O-β-D-(6-O-trans-feruloyl)glucopyranoside (17), and ovatosides A−F (18)(19)(20)(21)(22)24), together with 19 known compounds, 6-O-trans-feruloyl catalpol (3), 3,10 specioside (4), 11 6-O-(4-methoxy-trans-cinnamoyl) catalpol (5), 12 catalposide (6), 3 4′-methoxycatalposide (7), 13 vanilloyl catalpol (8), 14 6-O-veratroyl catalpol (9), 15 3,4-dihydrocatalposide (11), 5 6-O-trans-feruloyl-5,7-bisdeoxycynanchoside (12), 5 6-O-trans-isoferuloyl-5,7-bisdeoxycynanchoside (13), 5 6-O-(4-hydroxybenzoyl)-5,7-bisdeoxycynanchoside (14), 16 6-O-(4-hydroxybenzoyl)ajugol (15), 17 6-O-(4hydroxybenzoyl)phelipaeside ( 16), 5 grayanoside A (23), 18 darendoside A (25), 19 2-(4-hydroxyphenyl)ethyl[5-O-(4-hydroxybenzoyl)]-O-β-D-apiofuranosyl-(1→2)-β-D-glucopyranoside (26), 16 phlomisethanoside (27), 20 darendoside B (28), 19 and 8,5′-diferulic acid (29). 21 All isolates were tested for their ONOO − -scavenging activities.…”
