Neolignans of Virola carinata bark

Phytochemistry, 1982
Abstract Four neolignans, dehydrodieugenol, its monomethylether, carinatone and carinatin have been isolated from the hexane fraction of the bark of Virola carinata. Three new neolignans were separated from the chloroform fraction and examined by spectroscopy and chemical reactions.

Lignans from Virola aff. pavonis leaves

Phytochemistry, 1997
Abstract The petrol fraction of an ethanolic extract from leaves of Virola aff. pavonis yielded, beside five known lignans of the aryltetralin, arylnaphthalene and benzoylbenzylbutan types, the four new lignans:, rel-(7S,8S,8′R)-3′, 4′-dimethoxy-3,4-methylenedioxylignan-7-ol, 4-hydroxy-5-methoxy-3′4′-methylenedioxy-2,7′-cyclolignan-7-one, 4-hydroxy-5-

Neolignans from fruits of Virola elongata

Phytochemistry, 1985
Abstract Fruits of Virola elongata contain, besides the furofuranoid lignans eudesmin, epieudesmin and fargesin, the aryl-benzyl-methyl tetrahydrofuran neolignans magnostellins A and C. The absolute configuration of the magnostellins was detennined.

Neolignans from fruits of Virola pavonis

Phytochemistry, 1992
Abstract Virola pavonis was found to contain in the arils of its fruits 8.O.4′,7.O.3′-neolignans (eusiderins A, C and K) and a 8.O.4′-neolignan (of the β-propenylaryloxy-arylpropane type) and in the seed coats of its fruits 8.5′-neolignans (carinatone, carinatol) and 8.5′,7.O.4′-neolignans (dihydrocarinatin, carinatin).
