Phytochemical composition and biological activities of Orobanche crenata Forssk.: a review

The genus Orobanche includes about 100 different species. Among them, Orobanche crenata Forssk. (Orobanchaceae family), commonly known as broomrape, is a holoparasitic plant, noxious to legume crops that inhabits mainly in the Mediterranean basin. The aim of this review is to evaluate and organise the available reports on O. crenata. Our research revealed that the plant is edible, relatively safe to ingest, historically used for the treatment of skin infections, ulcers and bowel disorders. In addition, it represents a rich source of nutrients, antioxidant, antitumor and antimicrobial compounds. Phytochemical studies revealed the presence of twenty-two molecules, identified from different parts of the plant. The Prediction of Activity Spectra for Substances (PASS) analysis allowed predicting the biological activity of each compound. Furthermore, biological properties of O. crenata extracts were reported. Therefore, here we elucidate the botanic, phytochemical and biological profile of O. crenata, shedding light on a little characterised plant.
