A new phenolic-type compound containing a nitrogenous, heterocyclic-fused ring from the fruit of the argan tree, Argania spinosa (Skeels L.), is described. This and another already known compound also isolated in the course of the work belong to an obscure and rare class of natural products, the amino phenolics.

The title compound, C(14)H(18)O(3), is an important model compound in the synthesis of phenolic ethers. The cyclo-hexane ring adopts a chair conformation. In the crystal structure, adjacent mol-ecules are linked by O-H⋯O hydrogen bonds.

One new phenolic compound, sapnol A (1), and two new aromatic sophorosides, named saposides A (2) and B (3) were isolated from sugar maple sap. In addition, seven known phenolic compounds 4-10 were isolated. These structures were determined on the basis of NMR experiments as well as chemical evidence. Furthermore, all the isolated compounds 1-10 were tested for antioxidative activity by the sup...

A new phenolic amide 8, together with the nine known phenolic compounds 1-7, 9 and 10 were isolated from the MeOH extract of the roots of Paris verticillata. The structure of the new compound 8 was determined to be 1-N-feruloylaminobutyl-4-rho-hydroxybenzamide by spectroscopic methods. The isolated compounds were tested for cytotoxicity against four human tumor cell lines using the SRB assay.

The title compound, C(16)H(25)NO(2), which was synthesized by a Mannich reaction route, is a rare example of an organic compound containing the six-membered oxazine ring. The ring adopts a chair conformation and the N atom is pyramidal. The N atom serves as a hydrogen-bond acceptor to the phenolic OH group.

Objectives: Leaves and flowers ofElaeagnus angustifolia contain phenolic and flavonoid compounds. These compounds have antioxidant properties that protect cells from oxidative damage. The aim of this study was to determine and analyze total phenolic and flavonoid content of leaves and flowers in two E. angustifolia variants using different solvents (ethanol and methanol). Materials and Methods:...

Phenolic resins are important adhesives used by the forest products industry. The phenolic compounds in these resins are derived primarily from petrochemical sources. Alternate sources of phenolic compounds include tannins, lignins, biomass pyrolysis products, and coal gasification products. Because of variations in their chemical structures, the reactivities of these phenolic compounds with fo...
