Mineral element content of greater celandine (Chelidonium majus L.)

Chelidonii herba has long been known in herbal medicine for its choleretic, cholagogue, spasmolytic and antiviral activities. It is important to monitor the amount of mineral elements in Chelidonii herba preparations consumed mainly for their phytotherapeutical effects. In addition to organic compounds, dissoluble mineral elements in the teas and tinctures of herbs may also have a role in therapy. The concentration of 24 elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Ph, S, Ti, V, Zn) in crude drugs (herb and root), in their aqueous solutions (infusion, decoction) and alcoholic extracts were studied by ICP-OES. The difference between the concentration of elements in extracts - except for copper, manganese and sodium - was highly significant. It has been found that the root contains higher concentrations of mineral elements except for boron, copper, phosphorus and sulphur. The infusion contained most elements in the highest concentration and proved to be the best source for obtaining minerals. The same tendency was observed in the case of dissolutions. In aqueous extracts, the dissolution of mineral elements was between 10% and 65% for most elements, especially for potassium (65%) and phosphorus (54%). The dissolution of mineral elements in the case of tinctures decreased with increasing alcohol concentration. It may be stated that the presence of macro- and microelements in extracts greatly contribute to their therapeutical value.
