Exploring the phytochemical profile of Cytinus hypocistis (L.) L. as a source of health-promoting biomolecules behind its in vitro bioactive and enzyme inhibitory properties
Cytinus hypocistis whole plant and its three different parts (petals, stalks, and nectar) were chemically characterised and their biological properties evaluated. A total of 17 phenolic compounds were identified, being galloyl-bis-HHDP-glucose the most abundant. All the tested extracts showed high a...

| Sumario: | Cytinus hypocistis whole plant and its three different parts (petals, stalks, and nectar) were chemically characterised and their biological properties evaluated. A total of 17 phenolic compounds were identified, being galloyl-bis-HHDP-glucose the most abundant. All the tested extracts showed high antioxidant capacity, with the petals exhibiting the most promising results both in the OxHLIA (IC50 = 0.279 ng/mL) and TBARS (IC50 = 0.342 ng/mL) assays. For the antidiabetic and anti-tyrosinase enzyme inhibitory assays, the stalk extract presented the lowest IC50 values, 0.039 mg/mL and 0.09 mg/mL, respectively. Regarding antibacterial activity, all tested extracts displayed broad-spectrum microbial inhibition against both Gram-positive and Gram-negative bacteria. Similarly, all extracts displayed effective anti-proliferation activity against four tested tumour cell lines (NCI–H460, HeLa, HepG2, and MCF-7), with no toxicity observed for a non-tumour cell line. Considering the anti-inflammatory activity, the petals showed the highest nitric oxide inhibition (IC50 = 127 μg/mL). These results point C. hypocistis as a promising source of health-promoting biomolecules. |
