Studies in the Egyptian Medical Texts (1932–1935)

Studies in the Egyptian Medical Texts is a series of five philological articles by the English

Egyptologist Warren R. Dawson, published in The Journal of Egyptian Archaeology between 1932 and 1935. The five parts carry twenty-four numbered entries, each taking a word from the Egyptian medical papyri whose sense was disputed and arguing for an identification. The subjects are plants, animals, minerals, contested words and named afflictions. Entry 11, in the third instalment, concerns cannabis: there Dawson argues that

the plant name he transliterates šmšmt denotes hemp.

Whether cannabis is attested in pharaonic Egypt turns on that reading, which Dawson draws from the distribution of the prescriptions and from later Arabic medicine rather than from any statement the Egyptian texts make. … 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.
