“…It can be stated that high antioxidant activity could be attained by adding the bioactive compounds quantified in this study. A plethora of literature showed a positive relationship between specific bioactive compounds and antioxidant activity [ 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. In an earlier study, the antioxidant activity of OB-EO was reported as IC 50 6.68 mg/mL and 62.2 mg ascorbic acid equivalent (AAE)/g in DPPH and FRAP assay, respectively, and was ascribed to the presence of α-pinene, γ-terpinene, 1,8-cineole, limonene, linalool, and linalyl acetate [ 45 ], supporting the findings of the present study.…”

Antioxidant Effect of Ocimum basilicum Essential Oil and Its Effect on Cooking Qualities of Supplemented Chicken Nuggets

et al. 2022

A commonly observed chicken meat issue is its lipid oxidation that leads to deterioration of its organoleptic and nutritional properties and its further-processed products. Basil (Ocimum basilicum L.) is one of the traditional culinary herbs exhibiting food preservation properties. The current study investigated the essential oil composition, antioxidant activity and in vitro cytotoxic capacity of the essential oil of basil indigenous to Pakistan. GC–MS analysis of the essential oil revealed the presence of 59 compounds that constituted 98.6% of the essential oil. O. basilicum essential oil (OB-EO) exhibited excellent antioxidant activity, i.e., IC50 5.92 ± 0.15 µg/mL as assayed by the DPPH assay, 23.4 ± 0.02 µmoL Fe/g by FRAP, and 14.6 ± 0.59% inhibition by H2O2. The brine shrimp lethality assay identified an average mortality of ~18% with OB-EO at 10–1000 µg/mL, while that of the same concentration range of the standard drug (etoposide) was 72%. OB-EO was found to be non-toxic to HeLa and PC-3 cell lines. TBARS contents were significantly decreased with increase of OB-EO in chicken nuggets. The lowest TBARS contents were recorded in nuggets supplemented with 0.3% OB-EO, whereas the highest overall acceptability score was marked to the treatments carrying 0.2% OB-EO. The results suggest OB-EO as a promising carrier of bioactive compounds with a broad range of food preservation properties, and which has a sensory acceptability threshold level for chicken nuggets falling between 0.2-0.3% supplementation. Future research must investigate the antibacterial impact of OB-EO on meat products preserved with natural rather than synthetic preservatives.

“…There were around 30 identified compounds, in which tetracontane showed maximum area % and has already been reported to show antimicrobial and antioxidant properties [17][18][19][20][21]. In the literature, GCMS of Grewia tenax methanol-based fruit extract showed the presence of 82 compounds, predominantly 5,9-undecadien-2-ol, 6,10-dimethyl-as 11.60% whereas in aqueous extract it was 3.18% [10,17]. The green synthesis of AgNPs using GTB extracts showed a change in colour from light yellowish brown to dark brown within 10 min at room temperature and under continuous shaking.…”

Grewia tenax plant possesses many medicinal qualities that can be harnessed for bio-applications via nanotechnology in a cost-effective and environment-friendly manner. The synthesised silver nanoparticles (GTB-AgNPs) from Grewia tenax bark extract were first detected by observing the change in colour from yellowish brown to dark brown and confirmed by UV–vis spectroscopy. UV–vis spectral analysis recorded the surface plasmon resonance at 420 nm. In the current research, several process parameters (time, temperature, concentration of AgNO3 and the ratio of extract to AgNO3) were adjusted by using one variable at a time (OVAT) approach. Spectroscopy accompanied by dynamic light scattering (DLS), x-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersive x-ray (EDX) determines the size, nature, morphological variations and chemical constituents of GTB-AgNPs. The size range was found within 35−45 nm and the image clearly showed that the GTB-AgNPs were spherical in shape and well dispersed in nature. Zeta potential and Fourier-transform infrared spectroscopy (FTIR) were done to analyse GTB-AgNPs stability, dispersion and the biomolecules in aqueous bark extract liable for the bioreduction of silver particles. These GTB-AgNPs showed excellent antibacterial action against Gram-positive (S. aureus and B. subtilis) and Gram-negative bacteria (P. aeruginosa and E. coli) which was observed by disc diffusion assay. Congo red agar plate (CRA) assay effectively unveiled the antibiofilm proficiency of the particles. These studies displayed a reduction in bacterial sustainability and the formation of exopolysaccharides. Disc diffusion assay confirmed the antifungal competency against A. niger and C. albicans. SEM was performed to elucidate the intracellular breakage and morphological transformations in cells of Gram-positive bacteria and fungi after treatment with GTB-AgNPs. The current study, therefore, enlightened applications of GTB-AgNPs as an efficient antimicrobial agent and applicable substitute in the pharmaceutical area.

Background: Paroxysmal Supraventricular Tachycardia is a type of Supraventricular tachycardia (SVT) and is defined as intermittent SVT and typically presents with a ventricular rhythm of 160 bpm. The patient morbidity with paroxysmal supraventricular tachycardia (PSVT) is directly proportional to the frequency of episodes, and it can be life-threatening in patients with atrial fibrillation and ventricular pre-excitation. Its management depends and varies according to severity of the symptoms which includes long-term treatment to surgical procedure like catheter ablation. Case Report: A 26-year Female patient, who was a known case PSVT, approached with complaints of recurrent palpitations, chest discomfort with breathing difficulty, palpitation, lightheadedness and exercise intolerance. Conclusion: the patient was diagnosed as vataja hridaroga and treated with ayurvedic medicine for the duration of 3-4 months. With the help of ayurvedic medicines, patient is free from symptoms and chronic drug therapy.
