Inhibition activity of extracts from Aster scaber on α amylase

Sample	αAmylase inhibition activity (%)
	Phenolic content (μg/mL)
	50	100	150	200
Water extracts	2.00±0.14a1)	2.86±0.27a	9.71±0.11b	23.81±0.84c
Ethanol extracts	6.67±0.12a	48.57±1.05b	76.00±2.12c	88.57±0.97d
Acarbose	17.42±2.31a	20.33±1.72b	26.64±1.92c	40.03±2.31d

Mean±SD (n=6), means with different superscript letters within level are significantly different at p<0.05 by Duncan's multiple range tests. Acarbose was used for control.
