Novel aminoalkaloids from European mistletoe (Viscum album L.)

Antioxidant Activity of European Mistletoe (Viscum album)

(E,E)-alpha-farnesene the main substance of the volatiles of the flowers from European mistletoe (Viscum album L.).

(E,E)-alpha-Farnesene was extracted as the main component of the volatile fraction of male Viscum album L. Male and female flowers of V. album L. growing on different host trees were analysed by solid phase microextraction and by lipophilic extraction.

Inhibition of protein synthesis by a toxic lectin from Viscum album L. (mistletoe).

1. The haemagglutinating and toxic lectin from Viscum album L. (mistletoe) inhibits protein synthesis in a lysate of rabbit reticulocytes, with an ID50 (concentration giving 50% inhibition) of 2.6 microgram/ml. This effect is enhanced (ID50 0.21 microgram/ml) if the lectin is reduced with 2-mercaptoethanol. 2. The lectin inhibits protein synthesis also in BL8L cells in culture. Inhibition occur...

Isolation and properties of three lectins from mistletoe (Viscum album L.).

Three lectins have been isolated from an extract of mistletoe (Viscum album) by affinity chromatography on partially hydrolysed Sepharose and human immunoglobulin- Sepharose. The lectins differ in molecular weight and sugar specificity (lectin I, mol.wt. 11500, D-galactose-specific; lectin II, mol.wt. 60000, both D-galactose- and N-acetyl-D-galactosamine-specific; lectin III, mol. wt. 50000, N-...

Paediatric medulloblastoma cells are susceptible to Viscum album (Mistletoe) preparations.

BACKGROUND Medulloblastoma constitute more than 20% of all paediatric brain tumours and are the most common malignant brain tumours in children. Adjuvant chemotherapy has seen a strong increase in the use of complementary medicine for cancer treatment. Evidence for cytotoxic and apoptotic effects of Viscum album (Mistletoe) in vitro is available, however, no data concerning paediatric tumours, ...
