Non-alkaloidal constituents of Virola elongata bark
Phytochemistry, 1985Abstract Eleven of the major non-polar constituents of the dried bark of Virola elongata were isolated. A new neolignan, virolongin, two new lignans, dihydrosesartemin and β-dihydroyangambin, as well as the neolignan, eusiderin, the lignans, epi-sesartemin, epi-yangambin and yangambin, the cis and trans isomers of 3,5,4′-trimethoxystilbene and ...

Long chain esters of Virola species
Phytochemistry, 1987Abstract The esters of n -fatty acids and ω-hydroxy n -fatty acids of β-sitosterol, D -glucose and ferulic acid ( trans and cis ) as well as β-sitosterol, fatty acids and β-sitosteryl-β- D -glucoside were isolated from three Virola species and identified by optical data and chemical reactions. A novel series of acidic esters derived from C 22

Virola: A Promising Genus for Enthnopharmacological Investigation
Journal of Psychoactive Drugs, 1990Data are now available on the antifungal use of Virola from four countries and some 14 different tribes of Indians in these countries who employ the Virola exudate for the same or similar purposes. Three of the five methods of ethnobotanical investigation proposed by Schultes and Swain in 1976 have been employed in this ethnobotanical research ...

Aryltetralone and arylindanone neolignans from Virola sebifera
Phytochemistry, 1984Abstract The fruits of Virola sebifera contain several tetralone neolignans, including 2,4-dihydroxy-6,7-methylenedioxy-2,3-dimethyl-4-veratryltetralin-1-one. The 3-hydroxylated derivative of this compound may undergo a biosynthetic pinacol-pinacolone rearrangement to give 2-acetyl-3-hydroxy-2-methyl-5,6-methylenedioxy-3-veratrylindan-1-one which ...
