"An Account of the Plant, call'd Bangue" is a lecture delivered by Robert Hooke (1635–1703) to the Royal Society of London on 18 December 1689. Hooke's notes were found posthumously and published in 1726 by Richard Waller in Philosophical Experiments and Observations of the Late Eminent Dr. Robert Hooke. The lecture describes the effects of cannabis on a human subject (possibly Robert Knox, or Hooke himself) and represents the first detailed English-language scientific description of cannabis and the first recorded attempt to evaluate its therapeutic potential in a European institutional setting.

Hooke received the sample from Knox in September 1689, six weeks before delivering the lecture. Knox had encountered the plant during nineteen years of captivity in the Kingdom of Kandy, where he and a companion had used dried leaf mixed with jaggery to ward off fevers contracted from contaminated water during their escape attempts. … 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.
