This study purpose is to present data from an experiment realized in the city of Timisoara, during 2022. There were two investigated zones: urban and urban green and the studied species were Acer negundo, Acer platanoides, Liquidambar styraciflua and Cotinus coggygria. In the city of Timisoara, these species are quite commonly met on the boulevards or in parks. The investigated parameter was anthocyanin content. This parameter was analyzed using a non-invasive approach, OPTI-SCICENCES ACM-200 Plus Anthocyanin Content Meter and the results were presented in ACI. Data analysis was realized using Microsoft Office Excel 2016 and statistical processing was realized with PAST software v4.03. A total of 480 anthocyanins content samples were taken from all the species researched. In the end, each of the species researched (Acer negundo, Acer platanoides, Cotinus coggygria and Liquidambar styraciflua) had a total of 120 samples that were collected from both the Urban and Urban green zones. Readings were taken from multiple types of leaves, from both studied areas. The anthocyanin levels are the ones responsible for the red coloration of the plant tissue. Usually, a high level of anthocyanin accumulated in the leaf is a good indicator that the plant is under some environmental stress such as strong light, low temperature, certain herbicides, and pollutants and many more. If the leaves don’t present any kind of red coloration on them then the anthocyanin levels are between normal parameters, and we can say that the plant isn’t under any kind of environmental stress. From the collected data, it was observed that only in the urban green zone the distribution is normal, when compared to the urban zone, where the levels of anthocyanin are below average. In conclusion, it can be said that the anthocyanin content found in the leaves is influenced by the environment where the species is located, having lower levels in the urban area compared to the urban green one.
