An acylated allose-containing 8-hydroxyflavone glycoside from Veronica filiformis

Iridoid content and biological activities ofVeronica cuneifoliasubsp.cuneifoliaandV. cymbalaria

“…cuneifolia and V. cymbalaria hemoptysis, laryngopharyngitis, hernia, cough, and respiratory diseases, and are also used as an expectorant and antiscorbutic (Tomassini et al, 1995;Su et al, 1999;Grahamet et al, 2000). Earlier investigations performed on Veronica species resulted in the isolation mainly of iridoid glucosides, especially benzoic and cinnamic acid esters of catalpol, some phenylethanoid, and flavonoid glycosides (Chari et al, 1981;Taskova et al, 1998;Harput et al, 2002aHarput et al, , 2002bSaracoglu et al, 2002;Jensen et al, 2005). In this study, Veronica cuneifolia subsp.…”

Composition and taxonomic distribution of leaf flavonoids inHebeandLeonohebe(Plantaginaceae) in New Zealand — 1. “Buxifoliatae”, “Flagriformes”, andLeonohebe

“…The range of flavonoid glycosides found in Hebe and Leonohebe bears a striking resemblance to that identified in the related genera Veronica and Parahebe (Grayer-Barkmeijer 1978, 1979Chari et al 1993;Ozipek et al 2002). Within these genera, commonly, apigenin and luteolin and their 6-and 8-oxygenated derivatives occur, and are found variously as glucosides, glucuronides, xylosides, xyloglucosides, rhamnoglucosides, glucoglucosides, etc., just as in Hebe and Leonohebe (Table 2).…”

New Bisabolane-Type Sesquiterpenes from the Aerial Parts of Lippia dulcis

“…The present paper describes the isolation and structure elucidation of two new bisabolane-type sesquiterpenes (3, 4) along with five known flavonoids (5-9), three known phenylethanoid glycosides (10)(11)(12) and two known iridoid glucosides (13,14), as well as the anioxidative activity of eight phenolic compounds (5)(6)(7)(8)(9)(10)(11)(12).…”

“…The MeOH extract of the aerial parts of L. dulcis was successively subjected to Diaion HP20, silica gel, Sephadex LH20 and Chromatorex ODS column chromatographies as well as HPLC on ODS to afford twelve compounds (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14).…”

“…Compounds 5-14 were identified as cirsimaritin (5), 5) salvigenin (6), 6) eupatorin (7), 7) 5-hydroxy-6,7,3Ј,4Ј-tetramethoxyflavone (8), 8) 5,3Ј-dihydroxy-6,7,4Ј,5Ј-tetramethoxyflavone (9), 9) decaffeoylverbascoside (10), 10) acteoside (11), 11) isoacteoside (12), 12) 8-epiloganin (13) 13) and lamiide (14), 14) respectively, based on their physical and spectral data. Compounds 3 and 4 were obtained as a colorless oil.…”
