High-throughput phytochemical characterization of non-cannabinoid compounds of Cannabis plant and seed, from Pakistan.

摘要

The herbs are the natural resources for the infinite phenolic compounds that are used in pharmaceutical industry. These herbs are of significant importance due to their beneficial usage for the human health. Here, we studied a common herbs Cannabis sativa, an important member of the family Cannabaceae for phytochemical characterization. The methanol extract of whole Cannabis plant and seed was analyzed for the identification of non-cannabinoid compounds through High Performance Liquid Chromatography (HPLC) technique, because the non-cannabinoid compounds have not been much studied in C. sativa. These compounds are very useful in different diseases, used in cosmetics and as antioxidant agent. HPLC analysis revealed the presence of a variety of non-cannabinoid compounds including Quercetin, Gallic acid, p-Coumaric acid, m-Coumaric acid, Caffeic acid, Cinnamic acid, Ferulic acid, Benzoic acid and Kampferol. Furthermore, Quercetin was observed with high concentration in whole plant sample, whereas high Gallic acid and absence of m-coumaric acid was noted in the Cannabis seed. It was also observed that plant samples were with higher concentration of cinnamic acid as compared to seed. The Caffeic acid, Benzoic acid and Ferulic acid were in low concentration in both Cannabis plant and seed samples. Kampferol is another important non-cannabinoid compound that was also quantified in both samples. This research will be providing a foundation for further molecular characterization of Cannabis plant and seed for their beneficial usage.
