Embodiment 1

[0167] Embodiment 1: the preparation of the ferulic acid preparation of dilution

[0168] Formulations containing only ferulic acid in the appropriate working concentration range were prepared as previously described. For this purpose, 3 diluted formulations (referred to as "Formulation A") each with a final volume of 0.5 liters were prepared. The first formulation - Formulation A-I contained ferulic acid at a final concentration of 10 mM, the second formulation - Formulation A-II contained ferulic acid at a final concentration of 20 mM, and the last formulation - Formulation A-III contained ferulic acid at a final concentration of 40 mM acid. The composition of the final diluted formulation is shown in the table below.

[0169] Table 4: Composition of Diluted Formulation A

[0170]

[0171] Formulations A-I, A-II and A-III were prepared as follows. First, appropriate equal amounts of water and absolute ethanol (Merck S.A., Santiago, Chile) were mixed to form a 20% et...

Embodiment 2

[0172] Example 2: Ferulic acid, p-coumaric acid and caffeic acid and the mixing of ferulic acid and p-coumaric acid Preparation of concentrated preparations of substances and mixtures of caffeic acid and p-coumaric acid

[0173] Subsequently, a new set of formulations (referred to as "Formulation B") was prepared comprising a mixture of certain active compounds of the invention. The formulations also contain different concentrations of the active compounds, either alone or as part of a mixture. As a comparative reference against the previous group of formulations (Formulation A), a formulation containing only two different concentrations of ferulic acid was used. Formulation B is initially prepared as a concentrated solution of a compound of the invention in a suitable solvent. In formulation B, dimethylformamide (DMF) is used as solvent in a slight excess relative to that required to dissolve the required amount of active compound without heating. In this way, by suitab...

Embodiment 3

[0179] Example 3: Preparation of ferulic acid, p-coumaric acid and caffeic acid from concentrated solutions And the mixture of ferulic acid and p-coumaric acid and the mixture of caffeic acid and p-coumaric acid Diluents and dilute preparations

[0180] Concentrated Formulation B of Table 5 was diluted in dilutions prepared from the components and ratios shown in Table 6 immediately before administration. Diluents contain humectant-adherents and emulsifiers (Zoom , from ANASAC S.A.C.I., Santiago, Chile) and a volatile pH buffer (ammonium bicarbonate), both dissolved in water.

[0181] Table 6: Recipe for Diluent

[0182]

[0183] The dilution was prepared by dissolving 3.45 g of ammonium bicarbonate in 450 ml of water with stirring. Once the solids are completely dissolved, add 0.25ml of Zoom , and homogenize the solution for another 1 min. Finally, enough water is added to make 500ml.

[0184] Dilution solutions were prepared using this dilution to provide the...

Abstract

The invention is related to compositions and methods that naturally protect plant tissues against ultraviolet radiation and temperature, thus giving protection against sunburn to plants, plant parts, fruits and / or flowers during their development. The invention is also related to compositions and methods to naturally improve the color of plants, plant parts, fruits and / or flowers by inducing the natural synthesis of flavonoids and anthocyanins present in plants. Likewise, the present invention is directed to improving the nutritional value of plants, plant parts, fruits and / or flowers by increasing the normal levels of polyphenolic compounds, especially flavonoids, present therein. Additionally, the present invention is related to compositions and methods that give more resistance to plants, plant parts, fruits and / or flowers against pathogens as bacteria and fungi. Finally, the present invention is related to plants, plant parts, fruits, flowers and / or propagating material treated with the compositions described in the present document.
