“…By using a ferrous ion chelating assay, a nitric oxide radical scavenging assay, and a DPPH test, the antioxidant content of P. dioica leaf extract was determined. The occurrence of carboxylic acid, alkyl halides alkanes, and miscellaneous functional groups in P. dioica leaves have been reported by Murali et al [27]. Kharey et al [28] obtain green synthesized gold nanoparticles (AuNPs) using aqueous leaf extract of Pimenta dioica.…”

Green synthesis of gold nanoparticles (AuNPs) is of particular interest due to their catalytic, antioxidant, and antibacterial properties. In this study, the aqueous extract of Pimenta dioica leaves was used to synthesize AuNPs and the effective parameters were investigated. The prepared AuNPs were characterized by various techniques including UV–Vis absorption spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, Transmission Electron Microscopy (TEM), and X-ray diffractometer (XRD). The reduction and stabilization effect of the plant extract to fabricate AuNPs were explained by FTIR analysis. TEM imaging confirmed the formation of spherical-shaped AuNPs. The catalytic activity of synthesized nanoparticles was evaluated in the degradation of a Methylene Blue dye in the presence of NaBH4 as reducing agent and achieved after only two minutes. The AuNPs provided high antioxidant ability. In addition, the synthesized AuNPs showed a significant inhibitory effect against both gram-positive and gram-negative bacteria, where the zone of inhibition of 4 and 9 mm were obtained for synthesized AuNPs against S. aureus and E. coli, respectively.

“…The essential oil of allspice is a significant source of phytochemicals in medicine. Phytochemicals are a large group of plant-derived bioactive that may have diseasefighting properties [53]. Plants are one of the most important natural sources of secondary metabolites for medical purposes, due to their biological capacity to combat lethal or endemic diseases, as well as disorders that impact living beings.…”

Pimenta dioica L. Merrill. Myrtaceae family, known for its berries called pimenta or allspice, is one of the oldest spices in the world, widely used for its culinary and medicinal qualities. The main commercial product obtained from this spice is its essential oil, the reason for the interest in essential oil is based on the versatility of its use in different industrial areas (food, cosmetics, perfumery, and pharmaceuticals) due to its harmless and beneficial effects for health. In addition, it contains compounds that have shown broad biological activity, which turns out to be useful in the treatment of diseases related to the excessive formation of oxygen radicals. As a result, the extraction process and operating conditions have a significant impact on the bioactivity of these molecules. As a consequence, selecting the correct mix of variables to improve oil extraction and functionality is essential. The most of study on this essential oil is being focused on resolving these issues, as well as purification and identification. This chapter will cover the methods for obtaining P. dioica essential oil, as well as the chemical profile of the oil and its biological properties, which include its effects on humans, plants, animals, insects, and microorganisms.

An extensive range of lignocellulosic waste is used in mushroom growing, which is recognized as a very successful way to recycle agricultural waste and make food. Primary and secondary metabolites analysis is fundamental for further pharmaceutical studies. In this present study, physico-chemical analysis viz., moisture content, ash value, crude fat, crude fibre content, carbohydrates and protein content were evaluated in Pleurotus florida. Phytochemical analysis of inPleurotusflorida was done using four different solvents like hexane, chloroform, methanol and aqueous, using a standard protocol. The result of the present study showed moisture content (7.22±0.03mg/g), ash value (3.20±0.00 mg/g), crude fat (4.50±0.00 mg/g), crude fibre content (2.81±0.08 mg/g), carbohydrates (0.18±0.06 mg/g) and protein (0.36±0.11 mg/g). Qualitative analysis of P. florida showed the presence of alkaloids, anthraquinone, flavonoid, glycosides, phenol, saponin, steroid, tannin and terpenoid. The above compound is further estimated quantitatively. Aqueous extract of P.florida showed alkaloid (0.42±0.02 mg/g), anthraquinone (0.65±0.00 mg/g), flavonoid (9.19±0.00 mg/g), glycosides (3.40±0.04 mg/g), phenol (4.74±0.00 mg/g), saponin (12.1±0.03 mg/g), tannin (26.1±0.00 mg/g) and terpenoid (0.73±0.01 mg/g). Methanolic extract showed alkaloid (2.91±7.85 mg/g), anthraquinone (3.48±0.06 mg/g), steroid (2.34±0.01 mg/g), tannin (21.5±0.00 mg/g) and terpenoid (0.45±0.03 mg/g). The other compounds like alkaloid (0.78±0.00 mg/g), anthraquinone (1.79±0.01 mg/g), flavonoid (10.9±0.04 mg/g), glycosides (12.8±0.05 mg/g), phenol (39.3±0.00 mg/g), saponin (35.8±0.00 mg/g), steroid (3.47±0.00 mg/g) and terpenoid (0.34±0.02 mg/g) were showed in chloroform extract of P.florida. In hexane extract, an alkaloid (0.59±0.03 mg/g), saponin (2.58±0.00 mg/g), tannin (426±0.00 mg/g) and terpenoid (0.38±0.01 mg/g) were estimated. Finally, the secondary metabolites were employed as an ontology tool (Protégé), and the outcomes were displayed in diagrammatic form. Protégé tool is one alternative technology for using smart art diagrams like bar and pie diagrams in future quantitative analysis response compounds for further immune system development studies.
