“…On the other hand, bre contains the highest amount of CF (28.29%) and ash (12%); EE (%) of the leaf was identical to that of bre except in one genotype Brammonbaria (Table 1) [11]. In ax plants, seeds contain the highest amount of CP (21%) and EE (43.17%), and maximum CF (avg.…”

“…The nutritional aspects of both hemp and ax seeds and different plant parts were reported in different publications [10][11][12][13][14][15]. Although the physical properties of hemp and ax bres are known to us [1], hitherto, no information on the proximate composition of bres Bangladeshi genotypes of these two important bre-yielding crops is available.…”

Along with the apparel or clothing industry, diversified uses of natural lignocellulosic fibre are getting popularity in many fields e.g., composites, automotive, marines, aerospace, electronics, civil construction, nanotechnology, biomedical, etc. The property and uses of textiles are determined by their constituent fibre properties. The proximate composition and thermogravimetric analysis (TGA) data of a total of 9 local hemp and flax genotypes (3 and 6, respectively) were carried out to understand their suitability in different applications. A wide variation was observed in the ash content of hemp and flax fibres varied from 1.7 to 17.7%, Crude protein 3.27 to 9.02%, crude fibre 26.51 to 55.32%, ether extract 2.6 to 20.9% and energy value 284.44 to 383.96 kcal 100− 1 g. In TGA analysis, all the fibres showed a similar trend. The flax genotypes contain lower ash and ether extract and higher DM, crude carbohydrate and crude fibre than hemp genotypes. Therefore, flax could be used in the lightweight composite, textile, pulp and cellulose-based industries. The hemp fibre had higher ash which was reflected by a higher residue at 500 0C in TGA analysis. To understand the viability of these flax fibres, further investigations are needed.

“…Essential amino acids are defined as those that cannot be synthesized in our bodies, but instead have to be obtained through food. A 2014 study by Audu, Ofojekwu, Ujah & Ajima suggest that amino acids might be most concentrated within the leaves of the Cannabis sativa plant [69]. Some amino acids found in the leaf, stem and seeds of Cannabis sativa include lysine, histidine, arginine, aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, cystine, valine, methionine, isoleucine, leucine, norleucine, tyrosine, and phenylalanine [69].…”

The Cannabis plant (Cannabis sativa L.) produces an estimated 545 chemical compounds of different biogenetic classes. In addition to economic value, many of these phytochemicals have medicinal and physiological activity. The plant is most popularly known for its two most prominent and most studied secondary metabolites— Δ9-Tetrahydrocannabinol (Δ9-THC) and Cannabidiol (CBD). Both Δ9-THC and CBD have a wide therapeutic window across many ailments and form part of a class of secondary metabolites called cannabinoids—of which approximately over 104 exist. This review will focus on non-cannabinoid metabolites of Cannabis sativa that also have therapeutic potential, some of which share medicinal properties similar to those of cannabinoids. The most notable of these non-cannabinoid phytochemicals are flavonoids and terpenes. We will also discuss future directions in cannabis research and development of cannabis-based pharmaceuticals. Caflanone, a flavonoid molecule with selective activity against the human viruses including the coronavirus SARS-COV2, and certain cancers, is one of the most promising non-cannabinoid molecules that is being advanced into clinical trials. As validated by thousands of years of the use of cannabis for medicinal purposes, vast anecdotal evidence abounds on the medicinal benefits of the plant. These benefits are attributed to the many phytochemicals in this plant, including non-cannabinoids. The most promising non-cannabinoids with potential to alleviate global disease burdens are discussed.

“…AAs can also reduce environmental stress by scavenging free oxygen radicals, thereby contributing to antioxidant activity ( Calvo et al, 2014 ). The stem and leaves of cannabis, like other plants, contain various concentrations of incorporated AAs ( Audu et al, 2014 ). Plants can absorb and incorporate nitrogen in the form of intact AAs ( Persson and Nasholm, 2001 ; Sauheitl et al, 2009 ), and thus, solutions of protein hydrolysates and AAs can increase plant growth ( El-Ghamry et al, 2009 ; Talukder et al, 2018 ) and the nitrogen content of above-ground biomass ( Matsumoto et al, 1999 ).…”

Amino Acid Supplementation as a Biostimulant in Medical Cannabis (Cannabis sativa L.) Plant Nutrition

et al. 2022

There is growing evidence to support the involvement of nutrients and biostimulants in plant secondary metabolism. Therefore, this study evaluated the potential of amino acid-based supplements that can influence different hydroponic nutrient cycles (systems) to enhance the cannabinoid and terpene profiles of medical cannabis plants. The results demonstrate that amino acid biostimulation significantly affected ion levels in different plant tissues (the “ionome”), increasing nitrogen and sulfur content but reducing calcium and iron content in both nutrient cycles. A significantly higher accumulation of nitrogen and sulfur was observed during the recirculation cycle, but the calcium level was lower in the whole plant. Medical cannabis plants in the drain-to-waste cycle matured 4 weeks earlier, but at the expense of a 196% lower maximum tetrahydrocannabinolic acid yield from flowers and a significantly lower concentration of monoterpene compounds than in the recirculation cycle. The amino acid treatments reduced the cannabinolic acid content in flowers by 44% compared to control in both nutritional cycles and increased the monoterpene content (limonene) up to 81% in the recirculation cycle and up to 123% in the drain-to-waste cycle; β-myrcene content was increased up to 139% in the recirculation cycle and up to 167% in the drain-to-waste cycle. Our results suggest that amino acid biostimulant supplements may help standardize the content of secondary metabolites in medical cannabis. Further experiments are needed to identify the optimal nutrient dosage and method of administration for various cannabis chemotypes grown in different media.
