Hemp (Cannabis sativa) - An Underexploited but Promising Oilseed with Multifarious Properties and Applications: A Review
Get PDFHemp commonly known as bhang belongs to the Cannabaceae family. Due to the psychoactive effect, it is often stigmatised; however, recently the Government of Uttarakhand has legalised the cultivation of hemp in the state with <0.3 % 9-tetrahydrocannabinol levels. Hence this review provides comprehensive details on how the whole plant of hemp can be potentially used in various industries. Researchers identify hemp as a rich source of nutrients. Specifically, hemp seeds are being celebrated due to the presence of fatty acids, amino acids, and antioxidants. The presence of these nutrients makes hemp seeds a valuable ingredient in functional foods. Additionally, several studies recognised hemp for several health benefits viz., managing neurological disorders, preventing several cancers, easing skin problems and promoting better mental health. Alongside the health benefits, the hemp plant is recognised to have diverse applications in other industries such as cosmetics, textiles and construction. However, due to the legal constraints and local stigma large and nation-wide cultivation of hemp is difficult but extensive research into the cultivation and processing of hemp can help to leverage this plant for the associated benefits
Pathophysiology of Dermatophytes and Potent Phytochemical Sources as Possible Applications against Trichophyton Spp.
Get PDFTrichophyton infections are typically restricted within the epithelial keratinized layer of the skin and therefore grouped among the dermatophytoses. Different species of Trichophyton viz., T. mentagrophytes, T. rubrum and T. violaceum are the important causal agents for the dermatophytic disorders. Azole drugs are extensively employed in the therapeutic practice to treat dermatomycosis. Use of synthetic drugs can cause a number of side effects and may induce drug resistance to the patients. Therefore, plant extracts have been widely investigated as alternative for chemical drugs to solve this problem. Literature data revealed that specific plants showed inhibiting effect against particular species of Trichophyton because of their different phytochemical contents. This study is carried out to document different plant species for their antifungal activity against various species of Trichophyton. Total of 107 plant species belonging to 50 families have been gathered for their antifungal activity against nine species of Trichophyton species viz., T. asahii, T. erinacei, T. inkin, T. ovoides, T. schoenleinii, T. longifusus, T. soudanense, T. tonsurans and T. verrucosum
Eco-Friendly Synthesis of Silver Nanoparticles from Trans-Himalayan Herbs: A Comparative Study of Biological Activities
Get PDFThe current study aims to synthesise silver nanoparticles (AgNPs) using three medicinal plants-Inula racemosa, Rhodiola imbricata, and Ephedra gerardiana-native to the Trans-Himalayan region. These plants were specifically selected due to their well-documented ethnomedicinal uses and rich phytochemical profiles, particularly in phenolic compounds. The study aims to harness their bioactive potential for the development of eco-friendly, cost-effective nanomaterials with therapeutic applications. Synthesised AgNPs were characterised via UV–VIS spectrophotometer, SEM, FTIR, DLS, TEM and EDX analysis. The absorption peaks at 410 nm (I. racemosa), 440 nm (R. imbricata), and 420 nm (E. gerardiana), confirming nanoparticle formation via surface plasmon resonance. Phytochemical analysis highlighted phenolics as key agents in nanoparticle reduction and capping. Although the AgNPs showed lower antioxidant activity than the crude extracts but exhibited superior antibacterial efficacy against multidrug-resistant bacterial strains, outperforming the standard antibiotic Ampicillin. Cytotoxicity evaluation against MCF-7 breast cancer cells revealed that I. racemosa root extract and its AgNPs had the highest anticancer activity, with IC₅₀ values of 64.93 μg/mL and 55.88 μg/mL, respectively. This research proposes a sustainable approach to develop alternative antibacterial and anticancer agents, potentially addressing the rising global challenge of antibiotic resistance and cancer burden through plant-based nanotechnology
Characterisation, Synthesis, and Antimicrobial Activities of Silver Nanoparticles Formed via Green Synthesis Approach using Aqueous Extract derived from the Bark of Mangifera indica: A Sustainable Resource
Get PDFMany research opportunities have arisen as a result of the green synthesis method for nanoparticle creation and the rapid development and breakthroughs in nanotechnology. This study covers the one-step synthesis of silver nanoparticles (SNPs) from Mangifera indica bark aqueous extracts. Bark extract is combined with AgNO3 to perform green synthesis of SNP. The synthesised SNPs were characterised by a color change from light yellow to deep brown, as well as UV-VIS spectrophotometry in the 300-700 nm area. Further characterisations were carried out using Fourier transform infrared spectroscopy (FTIR) and X-Ray Diffraction (XRD) studies, followed by Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray spectroscopy (EDX) analysis. Phytochemical examination of crude bark extract revealed the existence of secondary metabolites alkaloids, flavonoids, phenolics, tannins, and saponins but no glycosides and starch were present. The antimicrobial activity (AMA) of Bark SNP (BSNP) towards gram-positive bacteria [Staphylococcus Aureus (SA) & Streptococcus Pyogenes (SP)], gram-negative bacteria [E. coli (EC) & Pseudomonas aeruginosa (PA)], and Candida species were determined using the disc diffusion technique. A single-factor ANOVA was used for performing the statistical analysis, and p-values < 0.05 designated statistical significance. The green synthesised SNPs were spherical and crystal size ranged between 10 and 12 nm on average. In UV-vis spectroscopy, the absorption spectra peaked at 460 nm. It was discovered that the SNPs’ antibacterial activity was stronger than their antifungal activities. Compared to commercial medicines, the BSNP exhibits a reasonable inhibitory effect. The purpose of the current study was to build a new, affordable, ecologically safe process for a plant-mediated green approach for SNP synthesis and evaluate its antimicrobial activity for sustainable resources
