بررسی برخی از متابولیت‌های ثانویه دارویی و آنتی‌اکسیدانی Dittrichia graveolens L. Greuter

Dittrichia graveolens (Asteraceae) is an aromatic and annual plant. The aim of this study is the evaluation of total phenolic, flavonoid and flavonol content, the antioxidant activities and other important medicinal secondary metabolites of this plant. According to the results, the total amount of phenols and flavonoid in different plant organs of D. graveolens were different in a way that the content of total phenols and flavonoid in the flowers and leaves were significantly more than the stems and roots. The content of flavonol in the flowers, leaves and stems were not significantly different, and the lowest content was observed in the roots. In addition, the linear and significant correlation coefficient was found between the antioxidant activity and the phenolic compounds in the extracts of different organs of the plant. The main components in different extracts were Bornyl acetate and α-Cadinol in flower extract, Borneol, Bornyl acetate, Thymol and Calarene in leaf extract and PMAMOMPE, Safrole, Carvacryl acetate, Vulgarone B and Bornyl acetate in root extract. On the whole, the current results compared with the results of other researchers indicates the remarkable impact of plant habitat on the quality and quantity of pharmaceutical compounds in different organs of the plant
