“…were observed between H-7 0 /C-7 and H-8 0 /C-8, which has been considered the main evidence that these carbons are directly involved in the bridge with the phenylpropane moiety [11,13,14]. Some of the assignments could be confirmed by NOESY correlations: H-4 with C-5 methoxyl protons, C-3 0 methoxyl protons with H-2 0 , and H-7 0 with H-6 0 .…”

The novel coumarinolignoid 5-methoxypropacin was isolated from the ethereal extract of the wood of the Amazonian species Protium unifoliolatum. Its structure was elucidated by spectroscopic methods as IR, 1D and 2D (1)H, (13)C-NMR and mass spectrometry. The regioisomer and the position of coumarin and arylpropanoid coupling were determined by long-distance C-H correlation (HMBC) and NOE experiments. Scopoletin and beta-sitosterol were also isolated and identified by the same physical methods.

“…The fruits, leaves, and roots of this plant have been used as a Korean traditional medicine for treating sore throat, respiratory illness, constipation, and dieresis [2,3]. Phytochemical investigations of A. fordii reported coumarins, diterpenoid esters, triterpenoids, and tannins [4][5][6][7]. Some phorbol diterpenoids isolated from A. fordii have shown Epstein-Barr virus activation effects and an enhancement of HTLV-I-induced colony formation of lymphocytes [8].…”

Three new neolignan glycosides (1–3), a new phenolic glycoside (15), and a new cyanoglycoside (16) were isolated and characterized from the twigs of Aleurites fordii together with 14 known analogues (4–14 and 17–19). The structural elucidation of the new compounds was performed through the analysis of their NMR, HRMS, and ECD spectra and by chemical methods. All isolated compounds were tested for their antineuroinflammatory and neuroprotective activities.

“…The families Celastraceae, Fabaceae, Euphorbiaceae, and Verbenaceae have a wide variety of tree species with a number of biological activities. Several species within these families are distributed in Cuba, and these include Tectona grandis (Verbenaceae), Aleurites fordii (Euphorbiaceae) (Fozdar et al 1989), Gliricidia sepium (Fabaceae) (Herath et al 1997), and Maytenus buxifolia (Celastraceae) (González et al 1997). These species are economically important and have been used in agroforestry systems or for various ethnobotanical applications.…”

Isolation and Phytotoxicity of Terpenes from Tectona grandis

et al. 2010

A study was carried out on the allelopathic potential of four forest species, Tectona grandis, Aleurites fordii, Gliricidia sepium, and Maytenus buxifolia. The most active species, T. grandis, was selected to perform a phytochemical study. A new compound, abeograndinoic acid, was isolated, and elucidation of its structure showed that this compound has an unusual carbon skeleton. A further 21 known terpenoids-including 4 sesquiterpenoids, 8 diterpenes and 9 triterpenes-also were isolated. A biosynthetic scheme for the presence of the new compound is proposed. Bioactivity profiles that used etiolated wheat coleoptiles and phytotoxicity bioassays on the isolated compounds were conducted. The compounds that presented the highest phytotoxic activity are the diterpenes 9 (2-oxokovalenic acid) and 12 (19-hydroxyferruginol).
