Viscum, auf Eichen

Cytotoxic constituents of Viscum coloratum.

Phytochemical studies on Viscum coloratum have resulted in the isolation of nineteen compounds. The structures of the isolated compounds were identified on the basis of 1D, 2D NMR and HR-ESI-Q-TOF-MS. Pachypodol (4) and ombuine (6) were characterized in the family Loranthaceae for the first time. 1,7-Bis(4-hydroxyphenyl)-1,4-heptadien-3-one (8) and 5-hydroxy-3,7,3'-trimethoxyflavone-4'-O-beta-D...

Two new phenolic glycosides from Viscum articulatum.

Two new phenolic glycosides, 1-O-benzyl-[5-O-benzoyl-beta-D-apiofuranosyl (1-->2)]-beta-D-glucopyranoside (1), and 4;-hydroxy-7,3;-dimethoxyflavan-5-O- beta-D-gluco-pyranoside (2), together with nine known flavanones 3 - 11, have been isolated from the dried whole plants of Viscum articulatum.Their structures were identified by extensive spectral analysis, especially 2D NMR techniques. Compound...

Soil Water, Temperature Regime and Growth of Young Oak Stands Grown in Lysimeters Subjected to Drought Stress and Air Warming

In a 3-year lysimeter experiment we investigated how young trees of Quercus robur, Q. petraea and Q. pubescens, growing either on acidic loamy sand or calcareous sandy loam, responded to an elevation in air temperature by 1-2°C and drought periods lasting several weeks. As intended, the water potentials were clearly lower in drought-treated soil than in the control treatment. Decreased evapotra...
