“This study investigates the phytochemical composition and biological activities of hemp (Cannabis sativa L.) leaves, flowers’ methanolic extracts from the Sofia variety, and its sprouts cultivated under different light conditions (natural light, darkness, blue, and white LED light for 5, 7, and 9 days).
Phytochemical analysis using HPLC identified four key polyphenolic compounds in sprouts’ extracts: chlorogenic, caffeic, and gallic acids, and myricetin, with a predomination of the chlorogenic acid. In contrast, leaves and flowers’ extracts contained cannflavins A and B and chlorogenic, p-coumaric, and ferulic acids, with a significant presence of isochlorogenic acid. Antioxidant capacity, assessed by FRAP method, revealed higher antioxidant potential in leaves compared to flowers and sprouts, with sprouts grown under blue and white LED lights exhibiting the highest activity.
Cytotoxic activity was evaluated on human colon cancer cell lines (HT29, HCT116, DLD-1) and normal colon epithelial cells (CCD 841 CoN).
Results demonstrated significant and selective cytotoxicity against cancer cell lines, with leaves showing more pronounced effects than flowers, and sprouts only moderate activity. All samples revealed an anti-inflammatory effect in vitro.
To conclude, sprouts, leaves, and flowers of the Sofia hemp may be considered promising products for chemoprevention in the future.”

“Cannabis sativa L. is a species of Asian origin that has been cultivated since ancient times for commercial, nutritional, and medicinal purposes.
The results indicate the interesting chemopreventive potential of sprouts, leaves, and flowers from Sofia hemp variety, manifested as cytotoxic, antioxidant, and anti-inflammatory activity.”
