Dandelion (Taraxacum officinale) is becoming an industry valuable crop due to the increase in its
utilization in the food and phytopharmaceutical industry. Nonetheless, its application is still limited
especially considering its extracts. Therefore, this study was aimed at exploring dandelion seeds as
a source of bioactive compounds. For this purpose, an environmentally friendly supercritical CO2
extraction technique was employed and extracts were separated at pressures of 10-45 MPa and a
temperature of 313 K. Obtained extracts were characterized using a gas chromatograph equipped
with mass spectroscopy (GC-MS), a gas chromatograph equipped with flame ionization detector (CGFID),
as well as by Folin–Ciocalteu and DPPH assays using a UV/VIS spectrophotometer. It was shown
that the selection of process pressure determined both extract yield and extract composition. An
increase in pressure increased extraction yield from 7.4 to 25.2% and the content of dominant linoleic
and olei...c fatty acids (from 536.3 to 658.3 mg/g and 125.8 to 161.7 mg/g, respectively). Total phenolic
and flavonoid content in obtained extracts ranged from 5.5 to 9.0 mg GAE/g and from 208.6 to 497.5
mg QE/g, respectively. The strongest DPPH radical scavenging activity with inhibition of 64.4% was
recorded for extract obtained at 10 MPa for extract solution concentration of 20 mg/mL. Obtained
results confirmed that extracts obtained from dandelion seeds are a valuable source of bioactive
compounds.
