Abstract
The methanol extract of various parts of Achillea wilhelmsii and their fractions were analysed for their antioxidant and antimicrobial activities. The methanol extract and the different fractions of various parts of the Achillea wilhelmsii are found to contain appreciable levels of total flavonoid and total phenolic contents. The DPPH radical scavenging activity and the inhibition linoleic acid peroxidation were also analysed. The plant extract and fractions were assessed against human blood erythrocytes for cytotoxic studies by haemolytic activity. The results of the present study have shown significant variations in the antioxidant activities of various parts of Achillea wilhelmsii and their fractions.
