| Species Name: Chelidonium majus | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Experiment Detail |
Aerial parts from five populations of Chelidonium majus were collected from the wild at the flowering stage (hereafter referred to as 'wild') for chemical analysis and biological activity testing during May 2019. Ten randomly selected plantlets were also collected from the same five populations in 2019 and planted in an organically certified experimental field of IES (57° 19′ 11.7″ N 25° 19′ 18.8″ E, 115 m altitude). The plot size was 0.8 m2, and the plant spacing was 0.2 × 0.5 m. A year later, aerial parts were collected during the flowering stage from the same populations in the experimental field (hereafter referred to as 'cultivated').

| Factor Function |
The total content of alkaloids in aqueous ethanol extracts prepared from cultivated C. majus specimens was higher than that observed in extracts prepared from wild-grown plant material. Chelidonine, sanguinarine, and chelerythrine were the main contributors to the total increase in alkaloid content. The cultivation of C. majus did not significantly affect the total content of flavonol glycosides. The observed differences in the phytochemical compositions of the C. majus extracts resulted in significant increases in the cytotoxic activities of the preparations.

| Species Name: Fusarium proliferatum strain BLH 51 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Factor Name: PDB Medium | [2] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Experiment Detail |
Strain BLH51 used in this study was 1 of 55 endophytic fungi isolated from the leaves of M. cordata from Dabie Mountain, China. The endophytic fungi isolates were inoculated, respectively, into 500 mL Erlenmeyer flasks containing 100 mL of potato dextrose liquid medium and cultured at 28 °C with 200 recycles/minute for 10 days in a rotary shaker.
