In this present work, the effect of variation of parts (pulp and peel) on photochemical 

compounds such as phenolics and flavonoids content of the banana flours were 

studied. The results exhibited that different varieties did exhibit significant differences 

on TPC as well as TFC which means that different sample yielded different values of 

TPC and TFC. The TPC was determined in ethanolic extracts of banana peel and pulp 

flour. The TPC was found to be about 0.40 mg/ml in banana peel and about 0.33

mg/ml in banana pulp. Thus, it is clear that the TPC was higher in the peel than in the 

pulp, while the total flavonoids content was determined in methanolic extracts of 

banana peel and pulp flour. The results showed that TFC was higher in banana peel 

(0.37 mg/ml) than in banana pulp (0.20 mg/ml). 

Key words: banana, catechol , quercetin, total flavonoids, total phenolics.

This research endeavor delved deeply into the potential protective efficacy of moringa extract in ameliorating renal impairments instigated by a high-fat dietary regimen in male rat models. The subjects were judiciously classified into six discrete cohorts, each comprising six individuals, with the subsequent allocation: Group 1 serving as the non-intervention control; Group 2 receiving a daily dose of 300 mg/kg body weight moringa extract (ME) spanning 8 weeks; Group 3 subjected to a sustained high-fat diet (HFD) throughout an 8-week interval; Group 4 exposed to a dual-modality involving an HFD and daily administration of 300 mg/kg bw ME for the identical duration; Group 5 subjected to the combined impact of an HFD and a daily 40 mg/kg bw dose of simvastatin (SIM) across 8 weeks; lastly, Group 6 subjected to a concurrent treatment approach involving an HFD, 300 mg/kg bw ME, and 40 mg/kg bw SIM, daily, over an 8-week period. Through an intricately orchestrated sequence of experiments, we embarked upon an expedition to unearth the Reno protective potential of moringa extract against dietary-induced nephrological impairment. Our findings offer an all-encompassing outlook on the synergy between dietary interventions and the innovative agents under scrutiny. This inquiry not only advances our comprehension of potential remedies for diet-associated renal adversities but also accentuates the emergence of moringa extract as a formidable contender in this domain. Our revelations illuminated that the application of a high-fat diet ushered in a substantial surge in malondialdehyde (MDA) levels, emblematic of heightened oxidative stress. This was concomitant with a marked depletion in glutathione (GSH), aggregate antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), and glutathione reductase (GSH-Rd) levels. Conversely, the administration of moringa extract adeptly mitigated these adverse repercussions induced by the high-fat dietary regimen.

AbstractIntroduction

The endemic species Nepeta cyrenaica Quézel & Zaffran, native to northeastern Libya, is valued as an important honey-bearing plant.

Objectives

This study was aimed to examine the micromorphology, phytochemistry, and bioactivity of in vitro-propagated N. cyrenaica for the first time.

Materials and Methods

The leaf indumentum was examined using light and scanning electron microscopy and further characterised for histochemistry. The chemical composition of essential oil (EO) was performed using GC-MS analysis, while dichloromethane (DCM), methanol (ME), ethanol (ET), and aqueous (AQ) extracts were analysed using qualitative and quantitative LC/MS analyses. The antioxidant activities of EO and extracts were assessed using three parallel assays, while enzyme-inhibiting effects were evaluated against four enzymes.

Results

The leaves bear various types of glandular trichomes, with lipophilic secretion predominating. The main EO component of EO was 1,8-cineole. A considerable number of phenolics and iridoids were tentatively identified in the ME extract. Quantitative LC/MS analysis confirmed that ferulic acid, rosmarinic acid, and epigallocatechin gallate were present in the highest amount in the extracts, in which three iridoids were also quantified. Although the ME extract contained the highest amount of polyphenolics and iridoids, the DCM extract showed the best overall biological potential. Additionally, EO exerted the strongest acetylcholinesterase and tyrosinase inhibition.

Conclusion

This study demonstrated that the endemic N. cyrenaica can be efficiently grown under in vitro conditions, where it develops various glandular trichomes that are thought to secrete and/or accumulate bioactive compounds with valuable medicinal potential.

In aquaculture, various natural feed additives are used to achieve farmed fish sustainability and maintaining a good health status, stimulate immunity, and prevent diseases of the cultured fish with better growth and less cost. Plant essential oils attract attention among these natural products as feed additives, as they are considered to be safe for animals, humans, and the environment. Besides that, many plant oils have used as a source partially or completely replace fish oil for reducing the cost of fish meals, yielding improved fish growth, fish health and survival after bacterial infection. The present article gives an idea about the recent studies that utilize plant essential oils as feed additives in many cultured fish species with different initial body weight, dose and duration.

The second stage, in which the star uses nuclear fuel in its interior, represents the helium burning phase. At that stage, three elements are synthesised: carbon, oxygen, and neon. This paper aims to establish a numerical solution for the helium burning system (HBN) fractal-fractional differential equations (FFDEs). The extended operative matrix method (OM) is employed in the solution of a system of differential equations. The product abundances of the four elements (helium, carbon, oxygen and neon) were obtained in a form of divergent series. These divergent series are then accelerated using Euler-Abell transformation (EUAT) and Pade approximation (EUAT-PA) to obtain more reliable results. Nine fractal-fractional (FF) gas models are calculated, and fractal-fractional parameters’ influence on product abundances is discussed. The findings show that modeling nuclear burning networks with the OM fractal-fractional derivative produces excellent results, establishing it as an accurate, resilient, and trustworthy approach, and the fractional HB models can have a considerable impact on stellar model calculations.
