Synthesis, biological investigation and catalytic application using the alcoholic extract of Black Cumin (Bunium Persicum) seeds-based silver nanoparticles

Bacterial infections are one of the most serious health problems all over the world, which cause need for the discovery of new drug. Since antibiotic resistance is a major threat to both humans and the environment, there is a need for studies on the antimicrobial properties of different forms of traditionally used plants. Herein, the seeds of coriander were used to isolate essential oil (EO) and to synthesise silver nanoparticles (C-AgNPs). The major oil constituents were characterized by GC-MS as Linalool (79.12%), Camphor (6.16%), γ-Terpinene (2.82%) and α-Pinene (2.67%). The synthesized AgNPs were characterized by UV-Visible spectrophotometry, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), X-ray difraction (XRD) and Fourier Tranmission Infrared (FTIR). The surface plasmon resonance (SPR) of C-AgNPs at 437 nm was recorded on the UV-Vis spectrometer. The spherical and homogenous of AgNPs was presented in SEM images. EDX showed elemental distribution and confirmed AgNPs. A characteristic intense peak was at 3.0 keV. The antibacterial activities of the essential oil and AgNPs form of coriander seed against Staphylococcus aureus ATCC 29213 and Escherichia coli ATCC 25922 bacteria were investigated by broth microdilution test. AgNPs and essential oil of coriander can be expected to provide future opportunities in nanomedicine and materials science. AgNPs can be displayed synergistic antimicrobial effect when used in combination with essential oil.

“…AgNPs were synthesized from methanol extract of R. stricta root with the help of silver nitrate. The AgNPs were found to be 20 nm in size and of spherical shape having potential inhibitory activity against Gram-negative and Gram-positive bacteria [50]. Another study revealed that AgNPs from R. stricta are toxic to dengue and malaria containing mosquitos.…”

“…The presence of secondary metabolites present in aqueous and ethanol extract was carried out by using standard protocols of phytochemical screening [49]. Phytochemical screening of R. stricta ethanol extracts demonstrated the presence of tannins, saponins, flavonoids, terpenoids, steroids, coumarins, and emodines which may act as a major source of reducing agents during the AgNP synthesis [50] (Table 1).…”

Rhazya stricta is a well-known medicinal plant and source of numerous potential secondary metabolites including steroids, alkaloids, and tannins. R. stricta possesses multimedical applications and used for curing of various diseases such as inflammation, diabetes, sore throat, infectious, helminthiasis, arthritis, and cancer. The current investigation deals with synthesizing AgNPs using aqueous and ethanol extracts of R. stricta. The synthesized R. stricta-AgNPs were characterized through UV-visible, Fourier transform infrared (FTIR), and atomic force microscopy (AFM) methods. The UV-visible analysis exhibited a characteristic absorption λ max at 475 nm in R. stricta ethanol AgNPs while this peak was absent in R. stricta aqueous crude extract. The thermal stability of R. stricta-AgNPs demonstrated that by increasing the reduction time and temperature, the absorption of AgNPs also increased, leading to more stable NPs formation. The FTIR spectra showed a broad peak at 450-550 cm-1 that confirmed the occurrence of AgNPs of R. stricta. The AFM study of the synthesized AgNPs revealed the spherical shape and size ranging from 30 nm to 90 nm. In antioxidant and antibacterial study, the R. stricta-AgNPs exhibited good antioxidant activity (87.94% and 88.37%) than the ethanol crude extract (50.00% and 56.81%) at 100 μg/mL using DPPH assay. Maximum antibacterial activity was recorded against Gram-positive bacteria (Staphylococcus aureus), which was 15 and 0 mm, while against Gram-negative bacteria (Klebsiella pneumonia) was found to be 16 and 14 mm, respectively, whereas against Bacillus subtills, a poor activity was recorded as 14 for extract and 0 mm for AgNPs, respectively. In the acetic acid-induced writhing model, the percent effect of extract (100 mg/kg) and AgNPs (15 mg/kg) was 79.98 and 83.23, respectively. The maximum muscle coordination effect of extracts in the inclined plan and traction test was 44% and 38% at higher doses. A mild sedative effect was also recorded against extract and AgNPs. The significant ( p < 0.05 ) effect of extract was noted at 100 mg/kg while AgNPs was more significant ( p < 0.01 ) at the tested dose of 15 mg/kg. These findings have concluded that R. stricta-AgNPs is an effective bioreductant of AgNPs synthesis and exhibit several applications in distinctive biomedical and pharmaceutical industries.

Medicinal or herbal spices are grown in tropical moist evergreen forestland, surrounding most of the tropical and subtropical regions of Eastern Himalayas in India (Sikkim, Darjeeling regions), Bhutan, Nepal, Pakistan, Iran, Afghanistan, a few Central Asian countries, Middle East, USA, Europe, South East Asia, Japan, Malaysia, and Indonesia. According to the cultivation region surrounded, economic value, and vogue, these spices can be classified into major, minor, and colored tropical spices. In total, 24 tropical spices and herbs (cardamom, black jeera, fennel, poppy, coriander, fenugreek, bay leaves, clove, chili, cassia bark, black pepper, nutmeg, black mustard, turmeric, saffron, star anise, onion, dill, asafoetida, celery, allspice, kokum, greater galangal, and sweet flag) are described in this review. These spices show many pharmacological activities like anti-inflammatory, antimicrobial, anti-diabetic, anti-obesity, cardiovascular, gastrointestinal, central nervous system, and antioxidant activities. Numerous bioactive compounds are present in these selected spices, such as 1,8-cineole, monoterpene hydrocarbons, γ-terpinene, cuminaldehyde, trans-anethole, fenchone, estragole, benzylisoquinoline alkaloids, eugenol, cinnamaldehyde, piperine, linalool, malabaricone C, safrole, myristicin, elemicin, sinigrin, curcumin, bidemethoxycurcumin, dimethoxycurcumin, crocin, picrocrocin, quercetin, quercetin 4’-O-β-glucoside, apiol, carvone, limonene, α-phellandrene, galactomannan, rosmarinic acid, limonene, capsaicinoids, eugenol, garcinol, and α-asarone. Other than that, various spices are used to synthesize different types of metal-based and polymer-based nanoparticles like zinc oxide, gold, silver, selenium, silica, and chitosan nanoparticles which provide beneficial health effects such as antioxidant, anti-carcinogenic, anti-diabetic, enzyme retardation effect, and antimicrobial activity. The nanoparticles can also be used in environmental pollution management like dye decolorization and in chemical industries to enhance the rate of reaction by the use of catalytic activity of the nanoparticles. The nutritional value, phytochemical properties, health advantages, and both traditional and modern applications of these spices, along with their functions in food fortification, have been thoroughly discussed in this review
