“…Phenolics in the extract mainly constituted gallic acid and quercetin (Kaisoon et al, 2011), whereas lutein is a major carotenoid present in marigold petals (Rivas, 1989 displayed the highest total phenolic contents of 79.04 and 78.18 mg GA/g dry marigold petal, respectively, followed by 'Sovereign Gold' and 'Rodeo Drange' . 'Columbus Drange' and 'Lunar Drange' showed the lowest total phenolic content.…”

Antioxidant activities and total phenolic content (TPC) were analyzed in ethanol extracts of 11 marigold cultivars grown in Thailand. Antioxidant activity assays performed in this study were the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical cation scavenging activity, ferric ion reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, oxygen radical absorbance activity (DRAC), and superoxide anion radical scavenging activity (SRSA) assays. 'Dptiva Drange' showed the best activity in the DRAC assay and in % SRSA, as well as the highest content of lutein (20.59 mg), gallic acid (25.77 mg), and quercetin (12.61 mg) per gram dry marigold petal among the 11 cultivars. Furthermore, 'Dptiva Drange' showed the highest lutein yield per plant, as compared to other cultivars. In contrast, 'Rodeo Gold' showed the highest activity by ABTS testing (0.92 mmol of trolox/g dry sample), as well as an 89.90% inhibition of DPPH. Lutein content showed a positive correlation with TPC and all antioxidant activity assays. In conclusion, 'Dptiva Drange' and 'Rodeo Gold' could be utilized as a good lutein source for functional food products and cosmetics.Keywords: marigold cultivars; antioxidant activity; phytochemical.Practical Application: Two marigold cultivars grown in Thailand showed high antioxidant activity among 11 cultivars tested.

“…These compounds have been related to the prevention of chronic degenerative diseases, such as diabetes, cognitive decline, and cardiovascular disease, as well as different types of cancer through the inhibition of their initiation and progression by modulating genes involved in key regulation processes (Anantharaju, Gowda, Vimalambike, & Madhunapantula, 2016;Gutiérrez-Grijalva et al, 2016). The flowers may contain a variety of these natural antioxidants such as phenolic acids and flavonoids, being their presence strongly related to their colour either directly (e.g., anthocyanins and other flavonoid pigments) or indirectly through the copigmentation processes (Brouillard, 1988;Kaisoon, Siriamornpun, Weerapreeyakul, & Meeso, 2011).…”

A B S T R A C TThe edible flowers are widely used, but there is still a lot to be done in relation to its bioactive potential and its correlation with the presence of phenolic compounds. The aim of this study was determined the individual phenolic profile in the hydromethanolic extracts and infusion preparations of four different flower samples (Dahlia mignon, Rosa damascena 'Alexandria' and R. gallica 'Francesa' draft in R. canina, Calendula officinalis L., and Centaurea cyanus L.) and their bioactive potential (antioxidant, antiproliferative, and antibacterial capacity). All the studied flowers presented different profiles regarding their phenolic composition and revealed biological potential. The bioactive potential of the studied flowers was moderate, the hydromethanolic extracts of rose petals showed the best results for antioxidant and antibacterial assays, while the antiproliferative properties were only present in some of the tested cell lines, for the hydromethanolic extracts, in which dahlia and rose showed the best results. These results demonstrate that edible flowers can be used as a source of phenolic compounds with bioactive potential, which can be applied in the food sector, as foods and as sources natural ingredients.

“…A capuchinha vermelha destacou-se pela maior quantidade de antocianinas totais (6.120mg/100g), seguida da capuchinha laranja (1.900mg/100g) e do amor-perfeito (940mg/100g). Kaisoon et al (2011) investigaram compostos fenólicos em 12 flores comestíveis da Tailândia. O conteúdo de compostos fenólicos variou de 37 a 89 mg GAE/g, sendo que Cosmos siamea e Cosmos sulphureus tiveram o maior teor de 88,5 e 86,8mg GAE/g, respectivamente, enquanto P. obtusa apresentou o menor teor (37,0mg de GAE/g).…”

“…Vários trabalhos têm demonstrado alta correlação entre grandes quantidades de compostos fenólicos e elevada atividade antioxidante em vegetais. O conteúdo de fenólicos totais também apresentou forte correlação com a atividade antioxidante em extratos de flores (DUBOST et al, 2007;TAI et al, 2011;KAISOON et al, 2011). Além do potencial antioxidante depender da estrutura química dos compostos fenólicos, sabe-se que um efeito antioxidante isolado pode reagir sinergicamente com outros compostos que contribuem para potencializar essa função (GIADA; MANCINI FILHO, 2006 …”

Compostos químicos e atividade antioxidante analisados emHibiscus rosa-sinensis L. (mimo-de-vênus) e Hibiscus syriacus L.(hibisco-da-síria) Chemicals and antioxidant activity analisys in Hibiscus rosa-sinensis L. (mimo-de-venus) and Hibiscus syriacus L. (hibiscus-the-syrian) Resumo O Hibiscus rosa-sinensis L. e o Hibiscus syriacus L., da família Malvaceae, são utilizados na área ornamental e gastronômica internacional, mas, nos últimos anos, vêm ganhando espaço como flores comestíveis não convencionais na alimentação alternativa. Este estudo objetivou quantificar a composição centesimal, pectina e compostos fitoquímicos dessas variedades de hibisco comparados com o potencial antioxidante detectado. As amostras das flores foram coletadas em uma propriedade agroecológica em Porto Alegre/RS no primeiro semestre de 2013. Utilizaram-se os métodos bromatológicos específicos para cada nutriente em base seca e úmida, e as análises fitoquímicas foram elaboradas com as flores frescas em três repetições distintas. No doseamento dos compostos fitoquímicos (polifenóis totais, antocianinas e ácido ascórbico), constatou-se que os hibiscos pesquisados possuem alta correlação no efeito da atividade antioxidante e suas propriedades químicas demonstraram valores significativos do ponto de vista nutricional, podendo ser utilizados como fonte alimentar com potencial para a manutenção da saúde e proteção contra patologias. Palavras-chave: Hibiscos; Propriedades químicas; Compostos fitoquímicos; Potencial antioxidante. SummaryHibiscus rosa-sinensis L. and Hibiscus syriacus L., Malvaceae family, are used ornamentally and in international gastronomy, but in recent years has been gaining ground as non-conventional edible flowers on alternative food consumption. This study aimed to quantify chemical composition, pectin and phytochemical compounds of these hibiscus varieties compared to the detected antioxidant potential. Samples of flowers were collected in an agroecological property in Porto Alegre, RS, in the first half of 2013. Specific bromatological methods were used for each nutrient, in wet and dry basis, and the phytochemical analysis was prepared with fresh flowers in three distinct repetitions. The phytochemical compounds quantification (total polyphenols, anthocyanins and ascorbic acid) showed that the evaluated samples have high correlation in the effect of the antioxidant activity and their chemical properties showed significant nutritional values and may be used as food source with potential for health maintenance and protection from diseases.
