    Background and Aims: Cuscuta sp. (Dodder), known as Ik & scedil;ut, is a parasitic herbaceous plant that negatively affects the yield and quality of cultivated crops; however, it has been used as an ancient medicinal plant for curing liver problems for centuries in the southeastern part of Turkey. The aim of this study was to investigate the total phenolic and flavonoid contents and mineral compositions of Cuscuta monogyna Vahl. subsp. monogyna Vahl. (CMM) grown on different host plants, along with their antioxidant activity, and to compare the host plant parts and their collected dodders. Methods: In this study, dodders were collected from host plants, including vineyardolive, pomegranate, green pepper, and liquorice in Turkey. The dodders were removed from their hosts before the drying process. Mineral contents were determined by Inductively Coupled Plasma Atomic Optical Spectroscopy (ICP-OES), and phytochemical contents were identified by chromatography. The total polyphenolic compositions and antioxidant activities were determined spectrophotometrically. Results: Because of the phenolic contents in the host plants and dodders, a significant variation was observed, with values ranging from 5.175% to 35.238%.. Different plant extracts and their varied dilutions had radical scavenging activity on 2.2-diphenyl-1picrylhydrazyl in the ranges of 57.78- 95.87%. Variations in mineral compositions were also determined in the dodders and their host plants. Conclusion: Mutualist or semi-parasitic plant communities share many phytochemical compounds and thus have the potential to exhibit similar activities. With regard to the obtained results, the chemical composition and pharmacological activities of dodder plants are closely related to their host plants.
