摘要：
A series of silicon-accumulating plants [different Equisetum (horse tail) species, Echium ulgare, and Symphytum officinale] were studied by solid-state Si-29 NMR experiments. For this purpose, selected parts of these plants were freeze-dried and then investigated by solid-state Si-29 VACP/MAS NMR spectroscopy. The Si-29 NMR spectra of these plants are quite similar and exhibit the typical pattern characteristic of polysilicic acid (amorphous silica).
