“…Regarding the group of flavonols studied, quercetin and kaempferol were found mainly in the onion samples. This result was expected as both compounds and their glycosidic derivatives are often found in these vegetables [65,66].…”

Fruits and vegetables are considered a good source of antioxidants, which are beneficial in protecting the human body against damage induced by free radicals and other reactive oxygen (ROS) and nitrogen (RNS) species. In this work, we aimed to evaluate the integral antioxidant activity (AOA) and determine individual polyphenols in fruits and vegetables of frequent consumption. For this purpose, an innovative and high throughput analytical approach based on original QuEChERS assisted by ultrasound extraction (USAE), instead of the manual agitation used in the classical procedure, was optimized and implemented for the isolation of polyphenols. The total phenolic content (TPC), flavonoids, anthocyanins, and betalains were evaluated using different spectrophotometric assays. In addition, free radical scavenging by methods 2,2’-azinobis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) and 2,2′-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) were used to estimate the AOA of the investigated fruit and vegetable extracts. Red onion, tamarillo, and beetroot were the samples with the highest AOA. The quantification and identification of free low molecular weight polyphenols from QuEChERS-USAE extracts was carried out by ultra-high-pressure liquid chromatography equipped with a photodiode array detection system (UHPLC-PDA). Catechin was the most abundant polyphenol, followed by gentisic and ferulic acids, mainly in the watercress sample. In relation to flavonols, quercetin and kaempferol were found mostly in onion samples, and in small quantities in tomato and watercress. The improved analytical approach, QuEChERS-USAE/UHPLC-PDA, offers an attractive alternative for the analysis of polyphenols from fruit and vegetable samples, providing several advantages over traditional extraction techniques, in terms of reproducibility, simplicity, low cost, analysis speed, and analytical performance.

“…For AC‐2, the m/z peak was observed at 301 [M − H] − suggesting the presence of a common aglycone moiety in AC‐1 and AC‐2 (Figure 3B). The literature shows that onion's outer scales are one of the richest sources of flavonoids especially, quercetin (molecular weight 302) and its glycosidic derivatives (Kwak et al., 2017; Sakai et al., 2003). Considering the published reports and m / z peaks observed in LC‐MS analysis in the present study, it was postulated that AC‐1 was quercetin glucoside and AC‐2 was quercetin.…”

The antioxidant‐mediated neuroprotective effect of Allium cepa outer scale extract (ACE) in mice with cerebral ischemia‐reperfusion (I‐R) injury was demonstrated in our earlier work. The current investigation aimed at establishing the bioactive component(s) responsible for this activity. Thus ACE was fractionated into ethyl acetate (EF) and aqueous (AF) fractions. These fractions were evaluated against cerebral I‐R injury in mice. I‐R injury in mice was induced by bilateral common carotid artery occlusion followed by 24 hr reperfusion. Memory, sensorimotor functions, cerebral infarct size, and oxidative stress were measured to address the neuroprotective mechanism of test substances. EF showed marked improvement of memory and sensorimotor functions by reducing brain oxidative stress and infarct size in mice after I‐R injury. The bioactive EF was subjected to chromatographic (HPLC‐PDA, HPLC‐MS, preparative HPLC) and spectroscopic studies to isolate and identify the neuroprotective compounds. This lead to separation of three components, namely quercetin, quercetin 4′‐O‐glucoside, and the remaining fraction, from EF. The separated components were biologically evaluated. These components showed improvement in mice with I‐R injury. But, EF displayed more marked neuroprotective effects as compared to the isolated components. The distinct neuroprotective outcome of EF may be credited to the synergistic action of compounds present in EF. Further studies such as evaluation of neurotoxic effects and other possible neuroprotective mechanisms are required to develop EF as a neuroprotective drug.

In this study, the short information was given about flavonoids giving yellow colour to plants present in nature. In addition to these, flavones, flavonols, flavanones and isoflavonoids as subgroups were also reviewed. Among these subgroups, flavones and flavonols are one of the most important classes of phenolic compounds. The information about the most important dye plants including flavonoids was also given in this study. The investigated plants are weld (Reseda luteola L.), onion (Allium cepa L.), young fustic (Cotinus coggygria SCOP), Anatolian buckthorn (Rhamnus petiolaris Boiss), dyer's greenwood (Genista tinctoria L.) and Spanish broom (Spartium junceum L.). The most important yellow dyestuff and the oldest European dye among these dye sources is known as the luteolin dye. The dye plants were used for yellow color dyeing in ancient and historical textile. Nowadays, flavonoids are reused for sustainable, non-toxic, green textile and environment friendly textile dyeing. In the same time, flavonoids have been used for natural lake organic pigment, cosmetic, pharmaceuitical industries. In recent years, it has been suggested to use flavones in textile dyeing, cosmetic, pharmaceutical, etc. industries by the World Health Organization (WHO). Therefore, we have aimed to contribute to similar studies theoretical and experimental in natural dyeing studies.Keywords: Flavonoid, natural dye, dye plant. ÖzBu çalışmada, doğadaki mevcut bitkilere sarı renk veren flavonoidler hakkında kısa bilgi verilmiş olup, ek olarak da, bu bileşiklerin alt grupları olan flavonlar, flavonollar, flavanonlar ve isoflavonoidler hakkında genel bilgiler sunulmuştur. Bu alt gruplar arasında flavonlar ve flavonollar fenolik bileşiklerin en önemli sınıflarından birisidirler. Flavonoidleri içeren en önemli boya bitkileri hakkında bilgiler de bu çalışmada verilmiştir. İncelenmiş bitkiler muhabbet çiçeği (Reseda luteola L.), soğan (Allium cepa L.), boyacı sumağı (Cotinus coggygria SCOP), cehri (Rhamnus petiolaris Boiss), boyacı katırtırnağı (Genista tinctoria L.) ve katırtırnağı (Spartium junceum L.)'dır. Bu boya kaynakları arasında en önemli sarı boyarmaddesi luteolin'dir. Anadolu ve Avrupa'ya özgü boyarmaddenin en önemlilerinden birisi olarak bilinir. Bir çok boya bitkisi antik ve tarihi tekstillerde sarı renk boyamacılığı için kullanılmıştır. Günümüzde, flavonoidler sürdürülebilir, toksik olmayan, eko tekstil ve çevre dostu tekstil boyamacılığı için yeniden kullanılmaya başlanmıştır. Aynı zamanda, flavonoidlerin doğal lak organik pigment, kozmetik ve ilaç endüstrisi için kullanımı yeniden artmıştır. Son yıllarda, Dünya Sağlık Örgütü (WHO) tarafından tekstil boyamacılığında, kozmetik ve ilaç endüstrileri ve benzeri alanlarda flavonların kullanımı önerilmiştir. Bu nedenle, bu çalışmada doğal boyarmaddelerin teorik ve deneysel benzer çalışmalara katkı sağlaması amaçlanmıştır.Anahtar Kelimeler: Flavonoid, doğal boya, boya bitkisi.
