Oxidative stress can be the result of normal metabolic activity or environmental factors. Geophytes, especially the Muscari Mill. species arc very important in the plant groups. Many kinds of flavonoids have been identified in Muscari Mill plants. Flavonoids have many functions in the biochemistry, physiology and ecology of plants. In this study we determined that phenolic contents of the ethanolic extracts higher than the methanolic extracts. The phenolic contents of the extracts as follows: Bulb ethanolic extracts (MBE) (52.23 +/- 1.32%) > Bulb methanolic extracts (MBM) (19.47 +/- 2.56%) and leaf ethanolic extracts (MLE) (31.68 +/- 0.92%) > leaf methanolic extracts (MLM) (26.73 +/- 1.08%). The absorbance of the Muscari parviflonun Desf. plant extracts at 470 rim were evaluated using beta -carotene-linoleic acid assay to determine the antioxidant activity. MBE showed the highest antioxidant activity with 76.8 +/- 1.51% and MLM showed the lowest antioxidant activity with 60 1.32% respectively. These values arc higher than the controls (methanol - 48 +/- 1.31%; ethanol - 31 +/- 2.12%). The free radical scavenging activities of the extracts were determined as follows: MLE (61.16 +/- 1. 42%), MLM (29.08 +/- 0.42%), MBE (44.80 +/- 0.81%), MBM (31.50 +/- 0.74%) respectively. Results show that, Muscari parviflorum has the antioxidant activity. |
