“…With respect to neem leaf extract prepared with water, for this plant, the water extract is more stable than other forms of extract [ 78 , 79 , 80 ]. The biological activity of neem extract can be attributed to the polyphenols it contains, as a recent study (2021) showed that rutin is the major phenolic component in neem extract [ 81 ].…”

Healthy, weaned, coccidial-free male rabbits from two breeds (New Zealand white (NZ) and V-line (VL)) were divided into 10 equal groups (5 groups each for NZ and VL) (3 replicates/group, 6 rabbits/replicate, 18 rabbits/group). All rabbits were inoculated with 5 × 104 Eimeria spp. oocysts (E. intestinalis (67%), E. magna (22%), and E. media (11%)) except for the rabbits in the first group (G1), which were inoculated with a sterile solution and served as a negative control. The remaining four groups were treated as follows: G2, no treatment/positive control, G3, treated with neem leaf extract, G4, treated with pomegranate peel extract (PPE), and G5, treated with a combination of neem leaf extract and PPE. For both breeds, our results showed that the use of neem leaf and/or pomegranate peel extract resulted in improved growth performance, with a significant improvement in relative feed conversion ratio (FCR) compared to the positive control groups, which recorded the worst values, as well as a significant (p ≤ 0.05) reduction in mean oocyst count compared to the positive control groups. We also observed downregulation of mRNA levels of IL-1βα, IL6, and TNF-α in the herbal treatment groups compared with the mRNA levels of these genes in the positive control groups. Herbal treatment with neem leaf and/or pomegranate peel extracts had positive effects on the NZ and VL rabbits experimentally infected with mixed Eimeria species, as evidenced by their healthy appearance, good appetite, no mortalities, an anticoccidial index > 120, and a significantly higher total return and net profit when compared to the positive control groups of both breeds. In NZ rabbits, the treatment with neem leaf extract alone (G3) or in combination with PPE (G5) recorded the most efficient economic anticoccidial activity.

“…Corn silk, an important TCM comprising the dried yellowish stigma and silk of corn fruit, has been widely applied for disorders such as diabetes , cancer , obesity , hypertension , inflammation , fatigue , and others . Modern studies elucidated that corn silk consists of numerous constituents such as polysaccharides , flavonoids , diterpenoids , alkaloids , steroids , and more . However, until now, the overall constituents of corn silk aqueous extract, especially the bioactive constituents, still remain unclear.…”

Corn silk is a well‐known traditional Chinese medicine that has been widely used for its antidiabetic, antioxidant, antihyperlipidemic, and other effects in China for thousands of years. Numerous studies have revealed that corn silk contains multiple bioactive constituents that are beneficial for human health. However, the constituents of corn silk in vivo remain ambiguous. In this study, high‐throughput ultra‐high‐performance liquid chromatography combined with quadrupole time‐of‐flight mass spectrometry technology using multivariate statistical analysis was established to systematically investigate the constituents migrating into blood from corn silk aqueous extract. As a result, 76 compounds were identified, including caffeic acid and ten of its derivatives, (E)‐p‐coumaric acid and two of its derivatives, ferulic acid and four of its derivatives, and five flavones. Among the identified constituents, 21 constituents, including nine prototype components and 12 metabolites derived from eight components, were characterized in sequence. Based on the significance of the results, the applied approach was powerful for the accurate determination and rapid screening of bioactive components from corn silk aqueous extract. The obtained results are valuable for the in‐depth understanding and further pharmacological study of corn silk aqueous extract.

“…PV of coffee oil samples increased significantly ( p < 0.05) during the storage process with increasing the storage period [Figure 1(b)]. These increases in peroxide values could be attributed to the formation of lipid hydroperoxides (Ali and El-Anany, 2017). These hydroperoxides are the primary oxidation products produced during the lipid oxidation process.…”

“…At the end of the storage period, AVs of coffee oils supplemented with DLGL powder were significantly lower compared to the FFAs value of the plain coffee sample [Figure 1(a)]. Lipid oxidation products can be formed through the oxidation and hydrolysis reactions during the storage process (Ali and El-Anany, 2017). Incorporation of DLGL powder into roasted coffee led to significant ( p < 0.05) decreases in AVs during the storage process.…”

Purpose The purpose of this study is to evaluate the effect of the addition of dried lemongrass leaves (DLGL) powder, at different levels, on phenolics content, antioxidant activities, consumer acceptance and the inhibition of lipid peroxidation of roasted coffee (RC). Design/methodology/approach DLGL powder was incorporated at the levels of 0%, 2.5%, 5.0%, 7.5% and 10% of RC weight. The total flavonoids (TF), total phenolics (TP) and antioxidant activity measured using a 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and reducing power assay of RC, DLGL and binary mixture of them determined. The oxidative indices of coffee oil samples during storage were investigated. In addition, the sensory characteristics of RC fortified with different levels of DLGL powder were evaluated. Findings The TP content of DLGL powder was 1,100.32 mg/100 g DWb, nearly 1.2 times higher than found in RC beans. The TF content of RC enriched with 2.5%, 5.0%, 7.5% and 10% DLGL were found to be around 1.05, 1.10, 1.15 and 1.20 times higher than that in the control coffee samples. RC supplemented with various levels of DLGL powder showed higher DPPH radical scavenging and reducing power activities. At the end of the storage period (six months), the acid, peroxide, P-Anisidine and total oxidation value values of RC supplemented with 10% DLGL powder were about 1.94, 2.52, 2.60 and 2.59 times as low as in the control sample without any addition of DLGL powder, respectively. RC containing 2.5% and 5.0% DLGL powder had significantly (p < 0.05) the highest sensory scores. Consequently, the addition of DLGL in coffee at up to a 5% ratio may have potential health benefits. Practical implications RC containing 2.5% and 5.0% DLGL powder had significantly (p = 0.05) the highest sensory scores. Originality/value Consequently, the addition of DLGL in coffee at up to a 5% ratio may have potential health benefits.
