Abstract

[automatically translated] The request of Hypericum perforatum by the pharmaceutical industry and cosmetics, and as a crude drug as that derived by the first processor, in these last years is increasing while its commercial availability still seems rather limited. The possibility of introducing in the Mediterranean cropping systems of the different species of Hypericum has become therefore potentially very interesting, but still requires the definition of many aspects of the response of the species for cultivation, both in open field and in pots, especially when it is conducted in environments different from those of natural vegetation. The deepening of these technical aspects would allow to optimize the yields both in terms of quantity and quality, respecting at the same time, the criterion of maximum efficiency in the use of productive resources. To this end, H. perforatum accessions from seeds from three different Italian regions, the North, respectively (Trento), center (Siena) and south (Agrigento), in autumn 2012 have been placed either in the open field and in pots , in order to compare the bio-agronomic response and productive. The plants were grown in two distinct environments: at the corporate headquarters of the CRA-SFM, in the town of Bagheria (PA, approximately 55 m above sea level), where potted test has taken place, and the experimental farm "Sparacia" University of Palermo, in the municipality of Cammarata (AG; about 450 m above sea level), where the plants were placed in the ground. For the entire length of the cultivation, in both environments, the plants were constantly monitored to assess the growth and phytosanitary conditions. The collection of flowering tops was performed at maximum flowering, which took place in the period between June and July of the year following that of sowing. At the same time, on a representative sample of 5 plants for each accession and environment, the following parameters were measured: plant height, number of stems with and without flowers, fresh weight of the whole plant, fresh weight of the flowering tops, herbal weight (after drying air and shade) and dry weight (after drying in a stove at 105 ° C for 24 hh). representative samples of dried flowering tops for each treatment were subjected to extraction in ethanol, and on the obtained extracts they were determined the yields of hypericin, hyperforin and pseudohypericin. Among the different sources we have been highlighted interesting differences in the periods of flowering, in the amount of commercial product and collected in the content of active principles, with a particularly satisfactory productive response from dell'accessione Sicilian. H. perforatum is confirmed as a sort potentially very interesting in view of its introduction in the Mediterranean cropping systems, where it could play a significant role in the increase of the company's multi-functionality level. in quantity of commercial product and collected in the content of active principles, with a particularly satisfactory productive response from dell'accessione Sicilian.
