B, bulb; R, root; S, seeds. Aerial parts were used for rest of plants.

The extracting solvent is MeOH except when otherwise is indicated. AcOEt, ethylacetate; Aq, aqueous; Hx, hexane; Et₂O, ethyl ether.

Results are expressed as the mean ± S.D. (n = 3).

Data were analyzed by One-Way ANOVA followed by Dunnett test.

^*Significant difference between each treatment and the positive control are shown as p < 0.05.
