چکیده
BACKGROUND The purpose of this study was to examine the effect of a leaf extract from A. archangelica on the growth of Crl mouse breast cancer cells in vitro and in vivo. MATERIALS AND METHODS The antiproliferative activity of the extract was measured by 3H-thymidine uptake in the Crl cells in vitro. Twenty mice were injected with the Crl cells, and 11 of them were fed A. archangelica leaf extract, and the progress of the tumours was followed. RESULTS The leaf extract was mildly antiproliferative on the Crl cells with an EC50 of 87.6 microg/ml The antitumour activity of the extract was expressed in the mice by marked reduction in tumour growth. In the experimental animals, 9 out of 11 mice developed no or very small tumours, whereas control animals, not receiving the extract, developed significantly larger tumours (p<0.01), as estimated by Mann-Whitney U-test. The antitumour activity of the leaf extract could not be explained by the antiproliferative activity of furanocoumarins present in the extract. CONCLUSION The results demonstrate the antiproliferative activity in vitro and antitumour activity in vivo of a leaf extract from A. archangelica

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...
