Comparison of the antioxidant and phenol content of Scropholaria striata Boiss. In different parts of Ilam province

Scropholaria striata Boiss (.Scropholaria striata Boiss) is the name of the thirsty place of the most important herbs in the family of mummies. In Iran, the plant grows more in cold and mountainous regions of Zagros. Although the chemical composition of this plant has not been identified, the people living in the province of Ilam have been experimenting experimentally for the treatment of various diseases. The present study was carried out to analyze the effect of the region (climate) on the antioxidant activity and phenol content of this plant. For this purpose, three areas of Badreh, Darehshahr and Dehloran in the same direction (northeast) with a distance of 100 meters, the fruit-bearing branch of the plant were collected in June 1395 and coincided with the emergence of fruit. Antioxidant activity of methanolic extract of plant samples was measured by DPPH method and total amount of phenolic compounds was measured by Folin Seokalto method. After statistical analysis, the results indicated that the effect of the region on extract yield, total antioxidant capacity and total phenol was significant at 1% probability level. The highest efficacy (19.37 ± 3.7%), antioxidant activity (126.556 ± 0.96 μg / ml) and total phenol (55.76 ± 3.717 ± 55 μg / ml) In the Valley of Shahr region. So, climate change can cause some secondary compounds to be synthesized.
