Six limonoids, trijugins D–H (1–5) and methyl 8α-hydroxy-8,30-dihydroangolensate (6), two degraded limonoids, trichiconnarins A and B (7–8), and a pregnane steroid, 3β,4α-dihydroxypregnan-21-one (9), along with the known trijugin C (10) and 3β,4α-dihydroxypregnan-16-one (11) were isolated from twigs and leaves of Trichilia connaroides. Their structures were established on the basis of extensive spectroscopic...
Baseline drift is one of the important factors that affect the detection signals. At present it is very difficult to obtain ideal effect using many methods which filter baseline drift in the signal of brain blood stream in the process of measurement. In this paper a new method to remove baseline drift in the signal of brain blood stream was presented based on the cubic spline interpolation theory...
The effect of different oils on the absorption of carotenoids was investigated in mesenteric lymph duct cannulated rats. Sixteen treatment emulsions containing increasing concentrations of either lycopene (LYC) or astaxanthin (AST) (5, 10, 15, 20 μmol/L) were prepared with olive oil or corn oil and continuously infused into the duodenum of the rat. Absorption of carotenoids into the mesenteric lymph...
The recent attention given to the possible role of α-tocopherol (α-Toc) and carotenoids in the prevention and treatment of a variety of illnesses resulted in segments of the population increasing their consumption of these nutrient/antioxidants. Once consumed’ α-Toc and carotenoids are thought to follow the same absorptive pathway and may influence each other's absorption’ particularly when taken...
The purpose of this study was to validate the use of the mesenteric lymph duct cannulated rat to study the absorption of carotenoids which do not have provitamin Activity. The absorption of two carotenoids, a hydrocarbon carotenoid (lycopene) and a xanthophyll carotenoid (canthaxanthin), were investigated. In the first experiment, lipid emulsions containing lycopene (LYC) or canthaxanthin (CTX) were...
