“…Although many fruits and vegetables contain lutein, the marigold flower is the best commercial source of pure lutein. Khalil et al (2012) have also studied the lutein and lutein ester extracted from the marigold flower (T. erecta) planted in Germany. They found that the T. erecta type 'Drangeprinz' was the richest source of lutein ester (14.4 ± 0.234 mg/g) in comparison with other Tagetes spp.…”

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.

“…Lutein esters are widely applied as food colorant to poultry feed and are recognized as essential human dietary supplements because they can inhibit age-related macular degeneration (AMD), protect against oxidative and bluelight damage in the retina, and are responsible for central and high acuity vision [1][2][3][4]. The lutein esters have higher bioavailability for administration and higher stability for storage than free lutein molecules [5].…”

An enzymatic route to synthesize lutein esters was investigated using a lipase-Pluronic conjugate as the catalyst. For the synthesis of lutein palmitate, the enzymatic process gave a conversion of 85 % for lutein and a product purity of 96 % at 50°C within 12 h, whereas the free lipase catalyzed process achieved a conversion below 10 %. To demonstrate the generality of this enzymatic process, lutein laurate, lutein myristate and lutein stearate were also synthesized achieving conversions of 73.8, 88.5, 84.4 % respectively. Moreover, the lipase-Pluronic conjugate can be reused for batches in the synthesis of lutein esters. As demonstrated by this study, the enzyme-Pluronic conjugate holds great promise for practical applications in industrial biocatalysis. Graphical Abstract An enzymatic approach to synthesize lutein esters was investigated using a lipase-Pluronic conjugate as the catalyst.

“…In literature, the lutein content of marigold flowers is usually reported for dry weight, and it varies widely depending on the variety. Examples of reported lutein contents (per dry matter) for different varieties of Tagetes erecta are 0.77-14.4 mg/g (Khalil et al 2012), 1.61-6.11 mg/g (Li et al 2007), 0.18-3.0 mg/g (Piccaglia et al 1998), and 10.3-17.0 mg/g (Deineka et al 2007). Deineka et al (2007) also measured the lutein content for fresh weight, and it was 2.10-2.97 mg/g with approximately 5-6 fold difference to content per dry weight.…”

“…Also the physico-chemical properties, such as solubility characteristics, of the encapsulated material can differ from those of the material without encapsulation. Different microencapsulation techniques, such as emulsification and spray drying, have been used to enhance the stability of carotenoids (Rodriguez-Huezo et al 2004, Khalil et al 2012. As carotenoids are mostly oil-soluble, simple oil-in-water (o/w) emulsions can be used to incorporate carotenoids into aqueous foods.…”

Marigold (Tagetes erecta) flowers are a rich source of organic solvents. In this study, lutein was extracted from marigold flowers with enzyme extraction without using organic solvents. Extraction produced oil that contained 0.36 mg/ml lutein (present as lutein esters but calculated as free lutein), and the yield was comparable to solvent extraction. The oil containing lutein was used to produce oil mixtures as stabilizers and some emulsions were also s containing lutein were stored in the dark at 20 monitored during storage. Stability of lutein was good in oil (85 emulsions (77-91%) but slightly worse in spray extraction of lutein from marigold flowers is a potential alternative to solvent extraction with comparable efficiency. In addition, there are no solvent residues in showed good stability of lutein in oil or in emulsions stored in the dark at room temperature, and these preparations could be used in different food products.
