It is well known that furostanol glycosides representing natural substances belonging to the class of saponines .Tomatoside – one of them – to be met in Lycopersicum esculentum seeds, were obtained through alcoholic extraction from tomato seeds and constitute bioactive substance of vegetal origin, having a wide variety of biological activities, especially antiviral and antifungical property. The chemical structure of such compound may be viewed as consisting of two distinct regions, namely the polysaccharidic chain and the genine part, having a rigid steroidal skeleton.The objective of the present paper is to promote this bioactive compound and evaluation of its biological activity. The influence of the vegetal compound with steroidal glycoside structure was studied on the apple tree plantation. The treatments consist of the spraing with aqueous solution of Tomatoside, in different doses and ways of using.The results of the experiments have emphasized the positive effects of the glycoside steroidal influence on the growth and quality development of the apple tree.
