Measurement of the Inhibition of Amyloid-β Aggregation using the Thioflavin T (ThT) Assay and the Inhibition of Amyloid-β Oligomerization using the Multimer Detection System (MDS) Assay.

	ThT Assay a (% Inhibition) c	MDS Assay b (Optical Density) c
Crude Alcoholic Extract	73.67 ± 3.54	2.559 ± 0.19 ^
Crude Base Extract	89.53 ± 5.21 *	2.027 ± 0.080 ^
Phenol Red (Positive Control)	70.06 ± 2.87
BPL-1 (Positive Control)		1.509 ± 0.18 ^
Negative Control		2.203 ± 0.068

^a The extracts and positive control were measured at 50 μg/mL and 50 μM, respectively. ^b The extracts and positive control were measured at 100 μg/mL and 100 μM, respectively. ^c The % inhibition and optical density are expressed as mean ± SD of triplicate experiments. * Significant difference at p < 0.05 versus the positive control (phenol red). ^ Significant difference at p < 0.05 versus the negative control.
