Phytochemical study of mineral elements of the medicinal plant (Tragopogon collinus) collected from the vegetation areas of northwest Iran

Therefore, the populations of a medicinal species that have grown in different ecological conditions form different and diverse types in terms of the quantity and quality of effective substances, which, of course, leads to differences in the range of medicinal and biological activity. to be For this purpose, to investigate the mineral elements of the medicinal plant Sheng from the Asteraceae family from three different habitats: Janvar Daghi from the slopes of the southern mountains at an altitude of 3800 meters, Qashka Balag in the southeast at an altitude of 2400 meters, Yilaq Kara Yatagh in the southwest in 1600 meters high, in Sablan area of ​​Meshkin Shahr city, located in the northwest of Iran and the soil where they grow. Mineral elements nitrogen, phosphorus, potassium, calcium, magnesium, sodium, iron, zinc, manganese, copper and cadmium were measured by flame photometer and atomic absorption spectrometer and compared with each other. Statistical analysis and averages by Duncan's test and drawing a graph showed that apart from magnesium, zinc, copper and cadmium elements, other elements under the influence of vegetation area have significant differences. Observations showed that Sheng medicinal plant has the highest amount of nitrogen, calcium and iron in Jenwar Daghi area and phosphorus and potassium in Gara Yatag summer cottage area. Also, the lowest amount of manganese was observed in Janwar Daghi region compared to the two regions of Qarayatagh and Qashqablag.
