Styryl-lactone derivatives and alkaloids from Goniothalamus borneensis (Annonaceae)

New Constituents from Stems of Goniothalamus amuyon

“…The H-5 and H-6 were also determined to be in the threo configuration as the result of J 5/6 (7.2 Hz) value. 9) In order to determine of the absolute stereochemistry of 1, (R)-and (S)-methoxy fluoromethyl phenylacetic acid (MTPA) esters of 1 (1r, 1s) were prepared. The 1 H-NMR data (see Table 2) of 1r and 1s indicated the absolute configuration of C-3 to be R. Thus, the chiral centers of 1 were evidenced as 2R,3R,4S,5S,6R.…”

Chemical Composition and Antibacterial Activities of Goniothalamus marcanii Flower Essential Oil

“…The seeds of G. amuyon are used to treat scabies, rheumatism and tympanites (Ahmad et al, 1991;Macabeo et al, 2013;Pradupsri et al, 2009). Characterizations of the chemical constituents of Goniothalamus plants resulted in the isolation of bioactive compounds including styryllactones, alkaloids, annonaceous acetogenins, flavonoids, azaanthraquinones and naphthoquinones (Cao et al, 1998). Essential oils from Goniothalamus leaves and stem barks mainly consists of monoterpenoid and sesquiterpenoids (Jantan et al, 2003).…”

Bioactive Goniothalamin from <i>Goniothalamus tapis</i> with Cytotoxic Potential

“…In Thailand, found nine species (Tip-Pyang et al, 2010). Phytochemical studies on some species of Goniothalamus have found several of this genus are discovered throughout the country such as acetogenins (Fujimoto et al, 1988;Gu et al, 1994;Jiang et al, 1997), alkaloids (Cao et al, 1998;Omar et al, 1992;Soonthornchareonnon et al, 1999), flavonoids (Deepralard et al, 2007;Likhitwitayawuid et al, 2006), styryllactone derivatives (Bermejo et al, 1997;Cao et al, 1998;Hisham et al, 2000;2003;Jiang et al, 2008;Lekphrom et al, 2009), furanopyrones (Bermejo et al, 1997;Fang et al, 1990;, arvensin, stigmasterol, (+)-aromadendrene, γ-gurjunene, goniothalamin, liriodenine and oxostaphanine (Ahmad et al, 1991;Hasan et al, 1994;Jiang et al, 1997). Therefore, Goniothalamus family could represent potentials sources of drugs for the treatment of cancers.…”
