Substances natural extracted


Are linear long chain aliphatic alcohols, or fatty alcohols, formed by a number of carbon atoms from 24 to 36 with an OH group terminal. Among the most interesting policosanols for the biological activities attributed to them are octacosanol and triacontanol, known as natural regulator of plant growth and active at very low concentrations.

Polyhydroxy aldehyeds, polyhidroxy ketones and their derivatives

These molecules are commonly known as carbohydrates. The main pathways of biosynthesis and carbohydrate degradation are an important component fo metabolism primary, essential for all organism.

Terpenoids and steroids

Terpenoids are a large family of natural substances, structurally different between themselves but all composed of C5 isoprene units coupled in spin mode. The possible rearrangement reaction consists in the loss of some carbon atoms which generates steroids. Saponins belong to this family, so called because plants rich in these substances were used for the washing (among these the Soapwort and the Quillaja saponaria).

Phenylpropanoid and aromatic polyketide derivatives

At the base of the C6 C3 phenylpropane units we find phenylalanine and tyrosine aromatic aminoacids. Among the aromatic polyketides we find flavonoids that are a huge class of metabolites. Flavonoids act as antioxidants and are widely used in the pharmaceutical industry. In plants they play an important biochemical and physiological role being necessary for the plant/environment
interaction, for symbiotic interactions and to react to stressful situations both biotic and abiotic.

Amino acid derivatives

Peptides and proteins are polyamides. Many structures have additional modifications to the system with respect to a polyamide base and this gives the molecule certain biological activities.
Glycine betaine (a glycine derivative) for example, is a molecule which carries out an osmoprotectant action, that is, it protects membranes and proteins from the effects of denaturants determined by high temperatures and saline stress.

These and many other substances synergistically with other amino acids, vitamins and trace elements, form and characterise VIRIDEM®. products.

Thanks to these substances, ILSA has managed to strengthen plant growth mechanisms. This is where our biostimulants come from and what they contain. Our biostimulants improve the physiological processes of plants, making them stronger, more productive and able to respond to situations of environmental stress.

All this was possible through the observation of the plants themselves, studying their metabolism and identifying the substances that they produce under certain conditions to then extract them for making our products to be applied to crops.

Innovative and very specific products capable of increasing the resistance of plants to abiotic stress, or capable of promoting their growth and the development of fruit, or suitable for improving the absorption of nutrients or, again, specific for the improvement of various quality parameters of the crop.

This is VIRIDEM® !
