Potato glycoalkaloids and their effect on soil ecosystem

abstract

English

This paper focuses on potato glycoalkaloids and their impact on the soil environment and organisms that are commonly found in close proximity such as mice, Wistar albino rats, Syrian golden hamster, Helix aspersa snails, Colorado potato beetle and filamentous fungi (Ascobolus crenulatus P. Karst, Alternaria brassicicola, Phoma medicaginis var. Pinodella and Rhizoctonia solan). Several extensive studies of potato glycoalkaloids have been conducted over the last decades. From the very beginning - from determining the presence of solanine and chaconin in potato tubers, hulls and roots, researchers have shifted to monitoring their toxicity (as early as 1933), the limit dose, and especially the impact on human helath. In recent years, they have been paying close attention as a potential therapeutic aid in the treatment of cancer, especially esophagus and stomach. The aim of this paper is to point out the need to study the fate of glycoalkaloids from an environment point of view, namely how their presence and subsequent degradation affect the soil environment and organisms living in the soil environment and its surroundings as relatively little information is available, especially on their mechanism degradation and decomposition intermediates. In the future, it is therefore essential to focus on how soil type of various physicochemical properties affects the degradation of potato glycoalkaloids-solanine, chaconin and the formation of their metabolites. So far, the effect of these pesticide-related toxins and their metabolites on commonly used compost worms such as the scented earthworm (Eisenia fetida), which are commonly found in soil and artificial composters, has not been reported. Planned studies for the future should contribute to a comprehensive understanding of the relationship between potato glycoalkaloids present in soil and the soil ecosystem.
