Abstract BACKGROUND Cannabis ( sativa L.) is one of the most controversial plants. So far, its multiple application in industry for production fabrics, paper and construction materials known. Today, there increasing interest medical purposes, as opposed to opiate activity. In addition well‐known cannabinoids, presence polyphenolic compounds their antioxidant reductive abilities are great importance. Therefore extraction both constituents, polyphenolics cannabinoids (Δ 9 ‐tetrahydrocannabinol...

Abstract Continuous exploration of innovative and sustainable solutions within green chemistry is imperative to tackle challenges inherent in traditional production processes. This study examined three novel methods for obtaining polyphenolic extracts from dill seeds: nonthermal high voltage electric discharge (HVED), subcritical water extraction (SWE), microwave‐assisted (MAE). SWE was conducted at temperatures ranging 100 200°C under 30 bar pressure, while MAE utilized a hydroethanolic...
