ANDRADE, F.M.C.; CASALI, V.W.D.  e  CECON, P.R.C.. Effect of dynamizations of Arnica montana in metabolism of chambá (Justicia pectoralis Jacq.). Rev. bras. plantas med. [online]. 2012, vol.14, n.spe, pp.159-162. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722012000500006.

Were evaluated the responses to dynamizations of Arnica montana in the growth and in the secondary metabolism of Justicia pectoralis expressed as coumarin production.  The studies were carried out at the Universidade Federal de Viçosa. The statistical design was completely randomized, with six replicates and five treatments, 30 experimental plots, one plant per pot. The treatments were dynamizations 3CH, 30CH, 60CH, 100CH and 200CH homeopathic preparation of A. montana. The application the treatments begun are planting seedlings, the aerial part being sprayed, at weekly intervals. After four months of planting, the plants were harvested. The evaluated growth characteristics were: fresh and dry matter of leaves and stems, fresh and dry matter of inflorecenses, and fresh and dry matter total. In the phytochemistry study, the production of the coumarin 1,2-benzopyrone was evaluated. Were no responses of growth characteristics. The dynamizations of A. montana caused changes in secondary metabolism of plants. The coumarin production with A. montana plants 3CH and 30CH were lower, increasing progressively from 60CH, and coming to increased in 100CH, followed by a large reduction in the 200CH. The homeopathic preparation A. montana cause change in secondary metabolism of chambá, and the responses depend on dynamizations.
