“…It grows naturally from spring until it practically disappears with the beginning of the winter, developing its complete life cycle within this period of time. This oil has wide applications as flavoring and perfume (Vasudevan et al, 1997). In addition, it is well known for its biocide properties (Zygadlo, 1994).…”

“…The two major classes of pigments present in the Tagetes spp. are the flavonoids and carotenoids (Vasudevan et al, 1997). The lutein ester carotenoids, in particular, have been identified as the principal pigment components in marigold flowers (Gong et al, 2012).…”

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.

“…The leaves are employed in kidney troubles and muscular pain, and the roots and seeds are used as purgative (Chadha, 1976). The chemical constituents of T. patula include alkaloid (Faizi & Naz, 2002), benzofuran (Menelaou et al, 1991), flavonoids and their glycosides (Bhardwaj et al, 1980;Ivancheva & Zdravkova, 1993;Koloshina et al, 1980;Mashkovskaja & Dzuba, 2002), helenien (Tarpo & Cucu, 1961), polyacetylene (Kyo et al, 1990;Towers et al, 1984), steroids and terpenes (Kasprzyk & Kozierowska 1996;Vasudevan et al, 1997), and thiophenes (Kagan, 1991;Kyo et al, 1990;Mares et al, 2002;Margl et al, 2002). The two major classes of pigments present in Tagetes are flavonoids and carotenoids.…”

The current study evaluates the antibacterial and antifungal activities of extracts from different parts of Tagetes patula Linn. (Asteraceae), reported for the first time in a single set of experiments. In the preliminary assay, the methanol extract of the flower (JFM) was found to possess antimicrobial activity against a number of bacteria with inhibition zone diameters ranging from 9 to 20 mm, the bioassay-guided fractionation of which led to the isolation of a flavonoid patuletin (3) in high yield as the active antibacterial principle with minimum inhibitory concentration (MIC) value of 12.5 µg/disk against Corynebacterium spp., Staphylococcus spp., Streptococcus spp., and Micrococcus luteus. Its glucoside, patulitrin (4), was found to be weakly active, except against Staphylococcus saprophyticus, Streptococcus fecalis, and Streptococcus pyogenes with inhibition zone diameters of 11, 16, and 12 mm, respectively. The cinnamate derivative (3b) of 3 showed antibacterial activity comparable with the parent flavonoid with a MIC value of 50 µg/disk against Corynebacterium spp., whereas benzoate derivative (3a) was found to be devoid of any activity; both the derivatives are new compounds. Moreover, the longchain alcohol 5, which displayed antibacterial activity in the preliminary testing, was obtained in large quantity directly from the petroleum ether extract of the involucre of the flowers.
