Figure 2.

Isoquinoline alkaloids content in aerial parts with fruits of C. majus collected from different habitat (70, 80, 90% of methanol acidified with 50 mM HCl; A–E—different habitats). Statistically significant differences in the content of each compound between plants harvested from five different habitats are presented as marks of the same shape and color; protopine—white circle, chelidonine—black squares, chelerythrine—white triangles, allocryptopine—white squares, no marks—no statistically significant differences.
