Studies for Component Analysis, Antioxidative Activity and α-glucosidase Inhibitory Activity from Equisetum arvense

This study was carried out to investigate the chemical components, and antioxidative and activities of Equisetum arvense extracts. In Equisetum arvense extracts were composed of 53.20% of crude fiber, 20.42% of crude ash, 15.32% of crude protein and 2.21% of crude fat. Potassium was the most predominant mineral and followed by phosphorus, calcium, magnesium, and sodium. The contents of the unsaturated fatty acids, such as linolenic acid, linoleic acid, and palmitic acid, were higher than those of saturated fatty acids. Seventy percent ethanol extract exhibited antioxidative activity with of . The Seventy percent methanol extract showed higher inhibitory activity than other solvent extracts.
