Cannabis cultivation is the growing of Cannabis sativa for fibre, seed, drug or multi-purpose use. Cannabis is a dioecious annual in the family Cannabaceae with a long history of agricultural use across Eurasia and, through later dispersal, every inhabited continent. Cultivation practices vary by use type, latitude, climate and legal context, ranging from rainfed smallholder fields integrated into mixed cropping systems to fully enclosed indoor production.

The crop is grown for several distinct end products, including bast fibre from the stem, seed for food and oil, drug preparations made from female inflorescences (such as ganja, charas, hashish and sinsemilla), and combinations of these. Modern commercial drug cultivation is largely based on F1 hybrid genetics propagated as clones, often grown indoors or in greenhouses, while landrace populations persist in traditional growing regions through ongoing mass selection by farmers. … read more →

Terroir-driven phenolic chemotypes and antioxidant/antimicrobial activities of Beldia (Cannabis sativa L.) seed extracts

Abstract Geographical variation in the phenolic composition and bioactivity of Moroccan Beldia (Cannabis sativa L.) seeds remains insufficiently characterized, limiting their rational valorization as bioactive resources. This study investigated aqueous extracts from defatted seeds collected in Ketama, Taounate, and Ouazzane using HPLC–DAD phenolic profiling, antioxidant and antimicrobial assays, and molecular docking. Data are reported as mean ± SD (n = 3), and regional differences were evaluated by one-way ANOVA followed by Tukey’s test when applicable. Clear regional discrimination was observed. Ouazzane gave the highest extraction yield (8.08 ± 0.24%), total phenolic content (16.13 ± 0.48 mg GAE/100 g DM), total flavonoid content (6.78 ± 0.20 mg QE/100 g DM), and total antioxidant capacity (565.80 ± 5.90 mg AAE/g), whereas Ketama showed the strongest DPPH scavenging activity (IC₅₀ = 10.25 ± 0.03 µg/mL). HPLC–DAD revealed distinct chemotypes dominated by 4-hydroxybenzoic acid (33.26–36.63%), with Taounate enriched in vanillic acid (35.00%) and caffeic acid (20.44%). Antimicrobial assays showed the best MIC values against Micrococcus luteus (0.50 ± 0.01 mg/mL) and Geotrichum candidum (0.12 ± 0.00 mg/mL). Docking highlighted flavonoid-type constituents as the most plausible active contributors, with catechin hydrate and rutin showing the strongest affinity toward CYP51 (-9.6 kcal/mol). Moroccan terroir strongly shapes the functional profile of Beldia seed extracts and supports region-guided sourcing for future bioactive applications.
