Cannabis botany is the study of the biology, morphology, physiology, ecology and classification of plants in the genus Cannabis. As one of the oldest cultivated plants, cannabis has been shaped by natural selection and millennia of human management across diverse environments, producing a wide range of forms adapted to local conditions.

Cannabis is a wind-pollinated, predominantly dioecious annual herb of temperate Eurasian origin. Glandular trichomes on its female inflorescences produce cannabinoids and terpenes; the plant displays high phenotypic plasticity and has co-evolved with human cultivation over millennia.

Whether the genus contains one highly variable species or several remains contested; major botanical databases generally treat it as a single species (Cannabis sativa L.) with internal subspecies and biotypes, while several cannabis-specific treatments recognise additional species. Cannabis is generally taken to be native to Central Asia. … 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.
