Abstract

Humans have used medicinal plants to treat various diseases for thousands of years. Cistus species are also widely used in traditional medicine and have various medicinal applications; therefore, they deserve more in-depth research. The present study evaluated the chemical profile, antioxidant, enzyme inhibition, and cytotoxic properties of the twigs and leaves of C. creticus L., C. laurifolius L., and C. salviifolius L. grown in Türkiye. Methanolic extracts of the three species were rich in phenolics, mainly flavonoids, and exerted potent antioxidant activity with methanolic extract from the leaves of C. salviifolius displayed the highest total phenolic (97.08 mg GAE (gallic acid equivalent)/g) and flavonoids (49.60 mg RE (rutin equivalent)/g) contents as well as antiradical (DPPH (2,2-diphenyl-1-picrylhydrazyl) assay = 612.11 mg TE (trolox equivalent)/g; ABTS ((2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) = 804.66 mg TE/g), reducing ions (CUPRAC (Cupric reducing antioxidant capacity) = 690.54 mg TE/g; FRAP (Ferric reducing antioxidant power) = 459.34 mg TE/g) and chelating (15.58 mg EDTAE/g) properties. It also revealed the best amylase and glucosidase inhibitory activity. Extracts from the twigs of the three Cistus species, besides the leaves of C. salviifolius and C. laurifolius displayed comparable acetylcholinesterase inhibitory activity (2.48 – 2.57 mg GALAE (galanthamine equivalent)/g). The twig of C. laurifolius also exerted the best antibutyrylcholinesterase (10.50 mg GALAE/g) and antityrosinase (73.15 mg KAE (kojic acid equivalent)/g) activities. C. creticus leaves revealed toxicity towards the RAW cell line (cell viability reduced to 68.8%) and were not toxic to normal cells (S17). In conclusion, these three Cistus species were shown to be a rich source of bioactive compounds with the potential for future applications in the food, pharmaceutical, and cosmetic industries.
