MACIAS-VILLAMIZAR, Víctor  e  CUCA-SUARE, Luís. Diaryldimethylbutane lignans and other constituents isolated from nectandra turbacensis (kunth) nees (lauraceae). Rev.Colomb.Quim. [online]. 2014, vol.43, n.1, pp.12-16. ISSN 0120-2804.  https://doi.org/10.15446/rev.colomb.quim.v43n1.50542.

Eight known compounds were isolated from the ethanol extract of bark Nectandra turbacensis (Kunth) Nees (Lauraceae); which were identified as meso-dihydroguaiaretic acid 1, threo-dihidroguaiaretic acid 2, sauriol B 3, and threo-austrobailignan-6 4; vitexin (8-C-β-D-glucopyranosyl-5,7,4'-trihydroxyflavone) 5; stigmast-4-en-3-one 6; and sitosterol 7/ stigmasterol 8 mixture. The structures of the compounds were elucidated by spectroscopic methods, techniques involving 1D and 2D NMR, GC/MS and by comparison of spectral data, reported in the literature, of related compounds. This is the first report of the presence of such compounds in the species. The chemotaxonomic implications are also described; related to the frequent presence of lignans in the genus Nectandra.
