Shelf 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 کاملFatty Acid Composition of Egg Yolk from Chickens Fed a Diet including Marigold (Tagetes erecta L.)
The objective of this study was to determine the effects of diet supplemented with marigold on egg yolk fatty acid composition and egg quality parameters. Sixty hens were assigned into three groups and fed diets supplemented with 0 (control), 10 g kg(-1), or 20 g kg(-1) marigold for 42 days. Eggs collected at the 6th week of the study were analyzed for fatty acid analysis. Laying performance, e...
متن کاملPETAL SENESCENCE IN CUT Tagetes erecta L. FLOWERS: ROLE OF PHENOLICS
Petals are an excellent model system for the study of fundamental aspects of senescence. The need of present study was felt with the aim to study the changes taking place during petal senescence in cut flowers of Tagetes erecta L. Estimation of total phenols was studied from first stage to senescent stage of Tagetes erecta L. The amount of total phenols had a decreasing trend with progressing s...
متن کاملIn vitro studies on the cytotoxicity, and elastase and tyrosinase inhibitory activities of marigold (Tagetes erecta L.) flower extracts
Marigold (Tagetes erecta L.) has long been used as a medicinal herb for a number of therapeutic activities. In the present study, the cytotoxicities of ethanol and ethyl acetate extracts of marigold flowers and their inhibitory effects on elastase and tyrosinase enzymes were investigated. An MTT assay was performed to measure the cytotoxicity of these two extracts on the H460 lung cancer and th...
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...
