2D NMR spectroscopic analyses of archangelicin from the seeds of Angelica archangelica.

Inhibition of acetylcholinesterase by extracts and constituents from Angelica archangelica and Geranium sylvaticum.

The aim of this study was to explore the acetylcholinesterase (AChE) inhibition of several Icelandic medicinal herbs. Ethanolic extracts of Angelica archangelica seeds and the aerial parts of Geranium sylvaticum proved effective, with IC50 values of 2.20 mg/ml and 3.56 mg/ml, respectively. The activity of imperatorin and xanthotoxin from A. archangelica was measured. Xanthotoxin proved much mor...

Accumulation of essential oils in relation to root differentiation in Angelica archangelica L.

The accumulation of essential oils in Angelica archangelica subsp. archangelica roots at different developmental stages was investigated through histochemical and chemical analyses. Roots less than 1 mm in diameter showed a primary diarch structure and two primary secretory ducts in the pericycle. These ducts were ephemeral and probably became dysfunctional early on. Oil accumulation was observ...

Metabonomic analysis of water extracts from different angelica roots by ¹H-nuclear magnetic resonance spectroscopy.

Angelica Radix, the roots of the genus Angelica, has been used for more than 2,000 years as a traditional medicine in Eastern Asia. The Chinese Pharmacopoeia records more than 100 herbal formulae containing Angelica roots. There are two common sources of Angelica roots, Angelica sinensis from China and A. gigas from Korea. The two species of Angelica roots differ in their chemical compositions,...

Evaluation of Antiseizure Activity of Essential Oil from Roots of Angelica archangelica Linn. in Mice

In the present study, the effect of essential oil of the root of Angelica archangelica Linn. was evaluated against electrically and chemically induced seizures. The seizures were induced in mice by maximal electroshock and pentylenetetrazol. The effect of essential oil of the root of Angelica archangelica on seizures was compared with standard anticonvulsant agents, phenytoin and diazepam. The ...
