In addition, two previously unknown compounds were found, namely a terpenoid glucoside lactone (suterolide, 21) and the phenylethanoid glycoside 2′′′′-<i>O</i>-acetyl-angoroside A (19) as well as verbascoside, echinacoside and tubuloside A(15–17, respectively). Two other species, <i>Jamesbrittenia dissecta</i> and <i>Lyperia antirrhinoides</i>, previously considered to belong to the same genus (<i>Sutera</i>) were shown to be members of two different genera, respectively. Significantly, these two species contained iridoids derived from 8-<i>epi</i>-iridodial (and 8-epideoxyloganic acid), namely aucubin (2), melittoside (3) and acetylharpagide (4). In addition we investigated <i>Melanospermum transvaalense, Lyperia tristis</i> and <i>Microdon dubius</i> likewise from Limoselleae and all of these contained iridoid glucosides from the 8-<i>epi</i>-pathway. Thus, secoiridoid distribution confirms the DNA-based circumscription of <i>Sutera</i> and its sister-group relationship with <i>Manulea</i>. In addition, the results show that the clade including these two genera has a biosynthetic pathway to iridoids fundamentally different from the rest of the tribe and from the whole family Scrophulariaceae.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Iridoid glucosides in the genus <i>Sutera</i> (Scrophulariaceae) as chemotaxonomic markers in tribe Limoselleae","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Sutera foetida; Sutera cordata; Melanospermum transvaalense; Scrophulariaceae; Secoiridoid glucosides; Iridoid glucosides; Phenylethanoid glycosides; Chemotaxonomy","OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2019-01-17","DateCreate":"2019-01-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000456755200019","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.phytochem.2018.10.021"},"refs":null,"anarec":{"AnaID":304584,"PubliDate":2019,"Pagination":"149-155","XtraPublOfAnaID":null,"ISBN":null,"Volume":"158","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43668,"SerRR":"Phytochemistry.
