Eight new vibsane-type diterpenoids, vibsanins P-W (1-8), were isolated from the methanol extracts of the leaves and twigs of Viburnum awabuki. The structures were elucidated by 1D and 2D NMR spectral analysis, and their cytotoxicity against selected cancer cells was measured in vitro.
Two new lignans, 3,4,4'-trihydroxy-3',9-dimethoxy-9,9'-epoxylignan (1), 3,4'-dihydroxy-3',4, 9-trimethoxy-9,9'-epoxylignan (2), together with one known compound, 4,4'-dihydroxy-3,3',9-trimethoxy-9,9'-epoxylignan (3), were isolated from the 95 % EtOH extract of Viburnum foetidum. The structures of
Four new iridoid aldehydes bearing (E)- or (Z)-p-coumaroyl group, luzonial A (1), luzonial B (2), luzonidial A (3), and luzonidial B (4), were isolated from a methanol extract of the dried leaves of Viburnum luzonicum collected in Kaoshiung, Taiwan and their structures were elucidated by analysis of
A new diterpenoid, dehydrovibsanin G (1), a new lignan, (+)-9'-O-senecioyllariciresinol (2), and six known compounds (3-8) were isolated from the branches and leaves of Viburnum odoratissimum var. odoratissimum. The structures of these compounds were elucidated by analysis of spectroscopic data.
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
Four new dammarane-type triterpenoids (1-4) and twelve known compounds (5-16) were isolated from the leaves of Viburnum sambucinum Reinw. ex Blume. Their structures were determined by spectral data analysis, including MS and 2D NMR. Cytotoxic activity evaluation in vitro against four cancer cell
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
Five new nor-dammarane triterpenes, 12β-O-acetyl-17β-hydoxy-3,15-dioxo-20,21,22,23,24,25,26,27-octanordammanran (1), 12β-hydoxy-17β-methoxy-3,15-dioxo-20,21,22,23,24,25,26,27-octanordammanran (2), 12β-O-acetyl-3,15-dioxo-17-en-20,21,22,23,24,25,26,27-octanordammanran (3),
The ethanol extract of the whole plants of Viburnum mongolicum afforded six new nor-dammarane triterpenoids: 3β,12β-dihydroxy-25,26,27-trinordammara-22-en -24,20-olide (1), 3β,12β-dihydroxy-24α-methoxy-25,26,27-trinordammara-20,24-epoxy (2),
BACKGROUND Lung cancer is one of the leading causes of mortality and morbidity. Viburnum grandiflorum is a medicinal herb known for its wide spectrum of pharmacological activities, but its anti-cancer properties against lung cancer cells have not been previously investigated. The present study
Vibsane-type diterpenes, the characteristic compounds of Viburnum odoratissimum, exhibited significant cytotoxicity in many cancer cells. To search for the potential target of vibsane-type diterpenes on lung cancer, we combined methods of network pharmacology prediction and experimental
In this study, the effects of gilaburu (Viburnum opulus) juice on colon tumorogenesis were investigated. Eight weeks old Balb-C male mice received subcutaneous injections of 1,2-dimethylhydrazine (DMH) (20 mg/kg body weight) once a week for 12 weeks. Both the sham control (group 1) and the DMH
Four new iridoids glucosides (1-4) and seven new iridoid aglycons (5-11) bearing (E)- or (Z)-p-coumaroyl groups were isolated from a methanol extract of the dried leaves of Viburnum luzonicum collected in Kaoshiung, Taiwan. The structures of the new compounds, named luzonoside A (1), luzonoside B
The triterpenes ursolic acid (1), 27-p-Z-coumaroyloxyursolic acid (2), 27-p-E-coumaroyloxyursolic acid, alpha-amyrine-3-palmitate and lupeol-3-palmitate were isolated through a bioactivity-guided fractionation from the acetonic extract of the aerial parts of Viburnum jucundum Morton in addition to
