Bioactive phenolic amides from Celtis africana.
Nine compounds have been isolated for the first time from Celtis africana, namely trans-N-coumaroyltyramine (1), trans-N-feruloyltyramine (2), trans-N-caffeoyltyramine (3), lauric acid (4), oleic acid (5), palmitic acid (6), lupeol (7), β-sitosterol (8) and oleanolic acid (9), respectively. Their structures have been elucidated by different spectroscopic techniques. The isolated compounds were ...
متن کاملTwo new phenolic amides from the seeds of Pharbitis nil.
Two new phenolic amides, pharnilatins A (1) and B (2), were isolated from the seeds of Pharbitis nil. These new compounds possess a p-coumaroyl unit with a structurally unique side chain, (2S,3S)-2,3-dihydroxyputrescine. The chemical structures and absolute stereochemistries of the new compounds were determined on the basis of spectroscopic analyses including 1D- and 2D-NMR experiments and chem...
متن کاملPhenolic Amides (Avenanthramides) in Oats – A review
Boz H. (2015): Phenolic amides (avenanthramides) in oats – a review. Czech J. Food Sci., 33: 399–404. Whole grain cereals such as oats are important sources of phenolic compounds. Oats contain phenolic amides, also named avenanthramides (AVAs), which have beneficial health properties because of their antioxidant, anti-inflammatory, and antiproliferative effects. The most common avenanthramides ...
متن کاملAntioxidant Properties of the Methanol Extracts of the Leaves and Stems of Celtis africana
The antioxidant activities of the methanol extracts from the leaves and stems of Celtis africana (Ulmaceae) were assessed in an effort to validate the medicinal potential of the subterranean part of the herb. The antioxidant activity and phenolic contents of the stem as determined by the DPPH, proanthocyanidins, total phenols, the flavonoids, and total flavonols were higher than that of the lea...
متن کاملBioactive phenolic constituents from the seeds of Pharbitis nil.
Two new lignans, termed pharsyringaresinol (1) and pharbilignoside (2), a new phenylethanoid glycoside, termed pharbiniloside (3), and 22 known compounds, were isolated from the ethanol extract of the seeds of Pharbitis nil. The structures of the new compounds (1-3) were determined on the basis of spectroscopic analyses, including 2D-NMR and circular dichroism (CD) spectroscopy studies. Among t...
