Tetrahydrofuran lignans from Viburnum betulifolium.[Pubmed: 27140524]
A phytochemical investigation of the EtOH extract from the aerial parts of Viburnum betulifolium Batal. afforded four new tetrahydrofuran lignans, betulifolium A-D (1, 2, 4, and 5), together with two known compounds vibsanol-9'-al (3) and sarcomeginal (6). This paper deals with the isolation and structure elucidation of the new compounds on the basis of spectroscopic methods, including 1D NMR, 2D NMR analyses and HR-ESI-MS data.
Deep simple epicotyl morphophysiological dormancy in seeds of two Viburnum species, with special reference to shoot growth and development inside the seed.[Pubmed: 21562028]
In seeds with deep simple epicotyl morphophysiological dormancy, warm and cold stratification are required to break dormancy of the radicle and shoot, respectively. Although the shoot remains inside the seed all winter, little is known about its growth and morphological development prior to emergence in spring. The aims of the present study were to determine the temperature requirements for radicle and shoot emergence in seeds of Viburnum betulifolium and V. parvifolium and to monitor growth of the epicotyl, plumule and cotyledons in root-emerged seeds.
Triterpenoids from Viburnum betulifolium.[Pubmed: 21279873]
Two new triterpenoids, ursa-12-sene-3β,11β-diol 3-O-palmitate (1) and ursa-12-sene-1β,3β,11α-triol 3-O-palmitate (2), were isolated from the 70% aqueous acetone extract of the aerial parts of Viburnum betulifolium, together with the artificial diene derivative of 2, ursa-12-dien-1β,3β-diol 3-O-palmitate (2a). Their structures were characterized by various spectroscopic methods, including 1D NMR, 2D NMR, and HR-ESI-MS.
