RANUNCULUS RIONII
LAGGER
Phylum: Magnoliophyta
Class: Magnoliopsida
Order: Ranunculales
Family: Ranunculaceae
Common name: Buttercup
Distribution: China, Afghanistan, Pakistan, South Africa, West Asia, Europe
Habitat: Lakes
Description: This annual herb has a branched, glabrous stem of 20 cm length.
The leaf blade is lagellate in outline, and lowers (1 cm diameter) have
small petals (4 × 2 mm) that are white and ovate.
Compounds and activities: The ethanol extracts of this plant species have
shown antioxidant and anticholinesterase (AChE) properties. The total phe-
nolic content of this species was found to be 66.9 ± 0.01 mg/g extract. With
regard to the antioxidant property of this species, the values of percentage
of inhibition ± SEM against the DPPH radical were 6.3 ± 0.41, 6.4 ± 1.39,
20.3 ± 0.84, 40.4 ±1.27, and 68.3 ± 1.02 for extract concentrations of 0.125,
0.25, 0.5, 1.0, and 2.0 mg/ml, respectively. With regard to the AChE inhi-
bition of the extracts of this species, the values of percentage inhibition ±
SEM against AChE were 7.3 ± 0.06 and 8.1 ± 2.09 for the extract concentra-
tions of 1 and 2 mg/ml, respectively (Kartal et al., 2009).
