Quantitative Determination of Total Flavonoids in Tagetes patula Marigold Flowers
نویسندگان
چکیده
Tagetes patula L. (marigold) is a valuable source of biologically active compounds, including flavonoids. A quantitative determination method for total flavonoids in T. flowers using differential spectrophotometry at analytical wavelength 428 nm and reference standard patulitrin (3,5,7,3?,4?-pentahydroxy-6-methoxyflavone 7-O-?-D-glucopyranoside) was developed during the present work. The error single ± 3.86% with confidence probability 95%. content varied from 6.12 0.07% to 8.30 0.12%.

Effects of Flavonoids from French Marigold (Florets of Tagetes patula L.) on Acute Inflammation Model
The major components patuletin and patulitrin were isolated from French marigold (florets of Tagetes patula). Patuletin and patulitrin were found to inhibit acute inflammation in mice. Oral administration of patuletin and patulitrin significantly suppressed hind-paw edema induced by carrageenin and histamine, while topical application of patuletin and patulitrin significantly inhibited ear edem...
متن کاملConstituents of French Marigold (Tagetes patula L.) Flowers Protect Jurkat T-Cells against Oxidative Stress
The flowers of French marigold (Tagetes patula L.) are widely used in folk medicine, in particular for treating inflammation-related disorders. However, cellular mechanisms of this activity demand further investigation. In the present work, we studied the potential of T. patula compounds to alleviate the oxidative stress in hydrogen peroxide-challenged human lymphoblastoid Jurkat T-cells. Crude...
متن کاملShelf stability of lutein from marigold (Tagetes erecta L.) flowers in vegetable oils
The stability of lutein in sunflower and rice bran oils was investigated in the temperature range 25–40 °C. Experiments were made using a standardized plant extract at 5% by weight of lutein derived from the flowers of Tagetes erecta L. Samples of the pigment in oil were incubated at each temperature for up to 10 days and the time course of degradation was monitored. A kinetic analysis of the d...
متن کاملStudies on the antioxidant and analgesic activities of Aztec marigold (Tagetes erecta) flowers.
Commercially available Aztec marigold (Tagetes erecta) flower extract (Af.Cr) was evaluated for the in vitro antioxidant activity and in vivo analgesic effect on acetic-acid-induced abdominal writhing. The results revealed the presence of pronounced antioxidant potential in Aztec marigold flowers and a dose-dependent (100 and 300 mg/kg) analgesic effect. The antioxidant and analgesic activities...
متن کاملIdentification and quantitative determination of flavonoids in the aerial parts of Teucrium polium by HPLC
Review of literature shows that large varieties of compounds have been found to bear hypoglycemic action. For instance, glycosides afford active principles that lower blood sugar in test animals. Following the I.V. administration of a 4 percent decoction of the dried T. polium herb, a definite reduction of blood sugar level has been exhibited. With reference to PDR for Herbal Medicines for the ...
