Cannabis indica Lam. is a historical botanical name originally published by Lamarck in 1785 for Indian drug-type cannabis specimens collected by Pierre Sonnerat. Its taxonomic status remains disputed. Major plant-name databases such as Plants of the World Online and World Flora Online currently treat C. indica Lam. as a synonym of Cannabis sativa L., while cannabis-specific taxonomic literature commonly retains indica-type plants at subspecies or variety rank within a monotypic C. sativa.

In the cannabis-specific literature, three positions persist. Monotypic treatments recognise only Cannabis sativa L. and place indica-type plants at infraspecific rank or treat them as synonyms. Polytypic treatments after Schultes et al. (1974) recognise C. indica as a distinct species, sometimes alongside Cannabis ruderalis. Intermediate treatments reduce indica-type plants to subspecific rank within C. sativa. A widely cited formal treatment in this last group, Small and Cronquist (1976), places drug-type plants as C. sativa subsp. indica (Lam.) E. Small & Cronquist. … 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.
