High impact information on Viburnum

• Furcatin hydrolase from Viburnum furcatum Blume is a novel disaccharide-specific acuminosidase in glycosyl hydrolase family 1 [1].
• Amentoflavone hexaacetate (AmAc) was synthesized from natural amentoflavone (Am), a biflavonoid extracted from Viburnum lantana L [2].
• Sterols, triterpenes and biflavonoids of Viburnum jucundum and cytotoxic activity of ursolic acid [3].
• Cytotoxic iridoid aldehydes from Taiwanese Viburnum luzonicum [4].
• Nine new diterpenes, neovibsanin D (1), 7-epi-neovibsanin D (2), 15-O-methylneovibsanin F (3), 14-epi-15-O-methylneovibsanin F (4), 15-O-methyl-18-oxoneovibsanin F (5), 2-O-methylneovibsanin H (6), 2-O-methylneovibsanin I (7), neovibsanin G (8), and 14-epi-neovibsanin G (9), were isolated from a methanol extract of the leaves of Viburnum awabuki [5].

Associations of Viburnum with chemical compounds

• Bioassay-directed fractionation of the methanolic extract of the leaves and flowers of Viburnum odoratissimum resulted in the isolation of two new diterpenes, vibsanol A (1) and vibsanol B (2), together with two new triterpenoids, 6beta-hydroxylup-20(29)-en-3-oxo-27,28-dioic acid (3) and 6alpha-hydroxylup-20(29)-en-3-oxo-27,28-dioic acid (4) [6].
• In addition to the five known compounds 5-epi-vibsanin H, vibsanins C, H, and G, and aldovibsanin B, four new diterpenes, 5-epi-vibsanin G (1), 18-O-methylvibsanin G (2), vibsanin M (3), and aldovibsanin C (4), were isolated from an acetone extract of the leaves and flowers of Viburnum odoratissimum by bioassay-directed fractionation [7].
• Three triterpenoids, 3-oxo-11,13(18)-oleanadien-28-oic acid, 24-hydroxy-3-oxo-11,13(18)-oleanadien-28-oic acid, 6 beta-hydroxy-3-oxo-11,13(18)-oleanadien-28-oic acid have been isolated together with the previously known virgatic acid, vibsanin B and 3-hydroxyvibsanin E from the leaves of Viburnum suspensum [8].
• The symptomatic species (from most to least sensitive) were Populus nigra, Viburnum lantana, Salix alba, Crataegus monogyna, Viburnum opulus, Tilia platyphyllos, Cornus alba, Prunus avium, Fraxinus excelsior, Ribes alpinum, and Tilia cordata; Clematis spp. did not show foliar symptoms [9].
• Petroleum ether, ethyl acetate and methanolic leaf extracts of Viburnum toronis Killip et Smith were studied [10].

Gene context of Viburnum

• In pollution exclusion experiments on the verge of a widely-used motorway, it has been shown that roadway emissions increase the abundance of the aphid Aphis fabae Scop. on two different host plants, Viburnum opulus L. and Phaseolus vulgaris L [11].
• Antinociceptive and uterine relaxant activities of Viburnum toronis alive (Caprifoliaceae) [10].
• The majority of species exhibiting a high grade of such cross-reactivity belonged to two genera, Viburnum of the Caprifoliaceae and Acer of the Aceraceae [12].
