Marigolds (Tagetes spp.) are major sources of bioactive compounds. The flowers used to treat a variety illnesses and have both antioxidant antidiabetic effects. However, marigolds exhibit wide range genetic variations. Because this, the compounds biological activities plants differ between cultivars. In present study, nine marigold cultivars grown in Thailand were evaluated for their compound content, as well activities, using spectrophotometric methods. results showed that Sara Orange cultivar possessed highest total carotenoid content (431.63 mg/100 g). Nata 001 (NT1) had amount phenolic (161.17 mg GAE/g), flavonoids (20.05 QE/g), lutein (7.83 mg/g), respectively. NT1 exhibited strong against DPPH radical ABTS cation, FRAP value well. Moreover, demonstrated most significant (p < 0.05) α-amylase α-glucosidase inhibitory effects (IC50 values 2.57 3.12 mg/mL, respectively). reasonable correlations capacity inhibit activities. Hence, may be good source lutein; it also beneficial functional food production medical applications.
