“…Other phenolic compounds (Gallic acid, dihydroxybenzoic acid, catechin, vanillic acid, epicatechin, p-coumaric acid, transferulic acid, quercitin, and trans-cinnamic acid) were present in small amounts. Caffeic acid was also reported the main phenolic acid compound present in lemongrass infusion (Coelho et al, 2016). Other phenolic acids (chlorogenic acid, p-coumaric acid, ferulic acid, quercitin, rosmarinic acid) that can arouse the antioxidant activities of lemongrass extract were also present in small amounts.…”

“…In this group, geraniol (16.67 AE 2.83%) was the main component, followed by citronellol (2.38 AE 0.45%) and 2,6,10-trimethyl-dodecane (0.69 AE 0.09%), respectively. Coelho et al (2016) also stated that citral and geraniol were the major volatile compounds of lemongrass extract. Through biological activities and flavouring properties of lemongrass, it has been used in beverages like yoghurt (Fattah et al, 2010), soy ice cream (Natisri et al, 2014), and ice cream (Chamchan et al, 2017).…”

Decoction extraction procedure was implemented to regain phenolic compounds from C. citratus leaves. The extraction variables, solid/liquid ratio (2-5 g/100 mL), temperature (85-95 C), and time (5-10 min) were assessed by central composite design for process optimization. Antioxidant activity (DPPH) and total polyphenol content (TPC) were monitored as responses. The TPC and DPPH were 71.98 AE 0.33 mg GAE/100 mL extract and 80.63 AE 0.49 mg TE/100mL extract respectively under optimal conditions (solid/liquid ratio ¼ 5, temperature ¼ 93.8 C and time 11.3 min). The evaluation of phenolic compounds and volatile compounds of C. citratus extract at conditions for optimum extraction revealed that caffeic (20.81 AE 0.003 mg/100mL) and syringic acids (18.63 AE 7.390 mg/100mL) were the main phenolic compounds while citral and geraniol were the primary volatile compounds. The results achieved herein suits the potential use of C. citratus extract as natural source of antioxidant and aroma compounds that can be employed in different industrial sectors. Practical application: Lemongrass obtained at the optimal extraction conditions is a good source of antioxidants and the extract has organic acids and a lemon scent due to the presence of citral. This extract can thereby be incorporated in the production of beverages which can help aromatize the beverage and also contribute in the addition of the antioxidant property of the beverage. It is also rich in organic acids, the main being propionic acid, which is known to have antimicrobial activity primarily against bacteria and mold. The lemongrass extract can therefore, extend the shelf life of the beverage they are incorporated in and also the citral present in lemongrass has antimicrobial properties.

“…The high weight gain in T4 and T5 could be attributed to the presence of phytochemicals in LGO. Scientific studies have shown that phytochemicals contains bioactive chemicals which are capable of performing antimicrobial [36], antiinflammatory [37,38], hepatoprotective [39][40][41][42], cytotoxic [43,44], antithrombotic [45], antidiabetic [46], miracicidal and cercaricidal [47], antioxidant [48,49], neuroprotective [50] antiplasmodial [51], antifungal [52,53], cardiovascular [29] and antiviral activities [33,54]. They also have the ability to reduce the invasion of pathogenic bacteria in the gastro intestinal tracts, thus preventing dysbiosis [15,55] scavenging free radicals [56][57][58] and growth improvement in animals [59][60][61].…”

This study was carried out to determine the effect of dietary supplementation of Cymbopogon citratus oil (LGO) on the performance and carcass characteristics of broiler chicks. A total of 250 one-day-old chicks of Ross 308 strain were divided into 5 treatments with 5 replicate per treatment of 10 birds in a completely randomized design. The dietary treatments include a control diet (T1) with no Cymbopogon citratus oil (LGO). LGO was supplemented at 0.1%, 0.2 %, 0.3 % and 0.4 % in diets 2, 3, 4 and 5 respectively. The experiment lasted for 56 days; feed and water were administered ad libitum. Results obtained revealed that average daily weight gain (ADWG), average daily feed intake (ADFI), average daily water consumption (ADWC) and feed:gain were significantly influenced by LGO (P˂0.05). Highest mortality was recorded in T1 (4.15 %) followed by T2 (1.71 %), T3 (0.50 %), none was recorded in T4 and T5 (P˂0.05). dressing percentage, carcass and relative organ weight were significantly different among the treatments (P˂0.05).There was no noticeable inflammation was observed on the liver, kidney spleen and other internal organs. It was concluded that LGO is rich in phytochemical constituents and can be safely included in the diets of broiler chicks up to 0.4 % level without causing any detrimental effect on the growth performance and carcass of birds.

“…Since herbal native infusions are receiving increasing attention for the number of physiological benefits they can bring to human health (Coelho et al, 2016) and as part of our continuing research of medicinal plants from Atacama Desert (Echiburu-Chau et al, 2017;Ardiles et al, 2018;Areche et al, 2020;Rodriguez et al, 2020) and native plants with potentiality as cholinesterase inhibitors (Barrientos et al, 2020a;Barrientos et al, 2020b), we investigated the infusions of the medicinal plant A. copa using screening tests to evaluate their antioxidant, antiprotozoal and enzyme inhibitory properties against cholinesterase and high-resolution UHPLC-MS/MS for the chemical profiling for the first time. Additionally, molecular docking of the major compounds was investigated.…”

Artemisia copa Phil. (Asteraceae) (known as copa-copa) is a native species of Chile used as an infusion in traditional medicine by Atacameños people in the Altiplano, highlands of northern Chile. In this research, we have investigated for the first time the cholinesterase inhibition potential against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), and the chemical profiling of the infusions prepared from the aerial parts of A. copa by high resolution spectrometry. In addition, total phenolic, total flavonoid content, antioxidant (DPPH, FRAP, and ORAC) and antiprozoal activity were tested. Artemisia copa showed good inhibitory activity against AChE and BChE (3.92 ± 0.08 µg/ml and 44.13 ± 0.10 µg/ml). The infusion displayed a total phenolics content of 155.6 ± 2.9 mg of gallic acid equivalents/g and total flavonoid content of 5.5 ± 0.2 mg quercetin equivalents/g. Additionally, trypanocidal activity against Trypanosoma cruzi was found (LD50 of 131.8 µg/ml). Forty-seven metabolites were detected in the infusion of A. copa including several phenolic acids and flavonoids which were rapidly identified using ultrahigh performance liquid chromatography orbitrap mass spectrometry analysis (UHPLC-Orbitrap-MS) for chemical profiling. The major compounds identified in the infusions were studied by molecular docking against AChE and BChE. The UHPLC-MS fingerprints generated can be also used for the authentication of these endemic species. These findings reveal that A. copa infusions can be used as beverages with protective effects.
