Memory-enhancing activity of plant extract.

Group	(TL) 8^th day (s)	(TL) 9^th day (s)	IR
Vehicle control (saline)	35.05 ± 3.17	30.96 ± 2.64	0.132 ± 0.288
Scopolamine (0.4 mg/kg)	60.74 ± 2.27	66.67 ± 0.76	0.88 ± 0.028
MBPL (200 mg/kg) + Scopolamine	55.36 ± 1.37	50.3 ± 0.99	0.1 ± 0.073
MBPL (400 mg/kg) + Scopolamine	50.5 ± 1.34	43.67 ± 1.69	0.156 ± 0.10
MGPB (200 mg/kg) + Scopolamine	53.12 ± 1.3	45.67 ± 1.85	0.163 ± 0.061
MGPB (400 mg/kg) + Scopolamine	39.16 ± 2.69	32.75 ± 1.89	0.194 ± 0.2147
Shankhpushpi + Scopolamine	36.16 ± 2.51	27.83 ± 2.1	0.299 ± 0.141
Piracetam (100 mg/kg) + Scopolamine	26.12 ± 2.6	21.78 ± 1.19	0.19 ± 0.611

MBPL and MGBP at both tested doses significantly reversed memory impairments induced by Scopolamine and are comparable to that of both controls. MGPD (400 mg/kg) exhibited the best memory-enhancing activity among all test samples, with minimum transfer latency time. All the data are calculated as average ± SD; n = 6. Data are statistically effective at and highly effective at in comparison to Scopolamine.
