Application of infrared spectral analyses for medicinal plants containing calcium (Ca2+)

A study was performed with the methods of Non-equilibrium energy spectrum (NES), Differential non-equilibrium (DNES), mathematical models and water cluster analysis on changes hydrogen bonds distribution in aqueous solutions due to calcium ions (Ca2+) from medicinal plants: Origanum vulgare L., Thymus vulgaris Mentha longifolia Petroselinum crispum Mill., Sideritis scardica Griseb., Salvia officinalis L. All them are known contain more than 1000 mg/100 g ions. The local maximum at (E = -0.1112 eV) (? 11.15 ?m) 897 cm-1) all investigated associated presence by Student’s t-test P<0,05. In proposed practical approach, had similar clustering patterns E -0.1387 eV, corresponding clusters 16-20 molecules. These findings different plant species further expand evidence about specific influence eV level solutions.
