symphytum/carbohydrate

The crude watery extract of Symphytum officinale and certain proteic and carbohydrate components isolated from it were studied for their effect upon the in vivo and in vitro proliferation of Ehrlich ascites cells, EL-4 cell line and of human T lymphocytes and upon the respiratory burst of human PMN

In root-layers of Symphytum officinale development as well as storage and consumption of carbohydrates is determined by day length, in a manner similar to that in plants developed from seeds. Root-layers differ in the following points: 1. Flowers are always formed after 16-19 leaves, even at a day

The development of the root and shoot system of Symphytum officinale always begins with the formation of a rape with 6-8 leaves on its epicotyl. After this stage development is determined by the length of the day. If the day is shorter than 15 hours, the subterraneous organs grow thicker. Flower

Enantioseparation of the pyrrolizidine alkaloid isomers intermedine and lycopsamine, isolated from Symphytum uplandicum, is discussed. The separatory power of two immobilized carbohydrate-based chiral HPLC columns, Chiralpak IA and IC, in different chromatographic conditions is compared. The study

We found that the total watery extracts obtained from roots of various plants such as Symphytum officinale, Phytolacca americana etc, precipitate human glycoproteins, agglutinate sheep red blood cells (SRBC) and stimulate lymphocyte adherence to nylon fibers. Five out of seven extracts precipitated
