Two glabretal-type triterpenoids from the heartwood of Aglaia ferruginaea

Bisamides, Lignans, Triterpenes, and Insecticidal Cyclopenta[b]benzofurans from Aglaia Species

“…A. ferruginea C. T. White & Francis). 32 In that paper, 13 C NMR data were listed but no assignments given. To support the structures of 12a+b unambiguously, all 2D methods mentioned above were used for clarification.…”

“…Based on the available data, Aglaia species are mainly characterized by cycloartane-type triterpenes. ,− Moreover, dammarane-type triterpenes, ,, tirucallanes, apotirucallanes, and related protolimonoids (glabretals) have also been isolated. The co-occurrence of structurally very similar cycloartanes and apotirucallanes in A. argentea Blume, , as well as dammaranes and a limonoid derivative in A. elaeagnoidea from Java, suggests close biogenetic connections between the different structural types.…”

“…A similar 13,14-cyclopropane derivative has also been isolated from A. tomentosa (syn. A. ferruginea C. T. White & Francis) . In that paper, 13 C NMR data were listed but no assignments given.…”

Silvaglins and related 2,3-secodammarane derivatives – unusual types of triterpenes from Aglaia silvestris

“…In addition, various derivatives of cycloartanes (Inada et al, 1997(Inada et al, , 2001Mohamad et al, 1997;Weber et al, 2000;Joycharat et al, 2008a), tirucallanes (Benosman et al, 1995;Puripattanavong et al, 2000), apotirucallanes (Mohamad et al, 1999a), glabretals (Mulholland and Monkhe, 1993;Su et al, 2006), baccharanes (Hwang et al, 2004a,b), and lupanes (Joycharat et al, 2008a) were also reported for the genus. Recently we established a new series of stereoisomeric 3,4-secodammaranes in A. silvestris (M. Roemer) Merrill, where the tetrahydrofuran (20,24-epoxy) ring linked to the D ring was characterised by the configuration 20R.…”

Molluscicidal activity of Aglaia duperreana and the constituents of its twigs and leaves

“…Various triterpenoids, including apotirucallanes [33], baccharanes [34], cycloartanes [35,36], glabretals [37], lupanes [36], tirucallanes [38], and secodammaranes [32,39], have also been isolated from the genus Aglaia. Dammaranes may be used as chemotaxonomic markers for A. odorata from Guangzhou, China, as reported in our previous study [14].…”
