Estimation of the Controlled Release of Antioxidants from β-Cyclodextrin/Chamomile ( L.) or Milk Thistle ( L.), Asteraceae, Hydrophilic Extract Complexes through the Fast and Cheap Spectrophotometric Technique.

This is the first study on the modeling of the controlled release of the estimated antioxidants (flavonoids or flavonolignans) from β-cyclodextrin (β-CD)/hydrophilic vegetable extract complexes and the modeling of transdermal pharmaceutical formulations based on these complexes using an overall estimation by the spectrophotometric method. The Korsmeyer-Peppas model was chosen for evaluating the release mechanisms. β-CD/chamomile ( L.

Quercetin Beneficial Role in the Homeostatic Variation of Certain Trace Elements in Dyslipidemic Mice.

Background: Quercetin's role in the homeostasis of certain trace elements in dyslipidemia induced in mice was assessed.

Methods: Forty BALB/ mice were allocated into 4 groups as follows: control; HFD, received fat diet; HFD +  group, received HFD +500 mg/L quercetin; and blank control ()-normal food + 500 mg/L quercetin in drinking water.

Results: By analyzing the values of total proteins, albumins, cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, and the levels of several trace elements in blood and organs, we perceived a statistically significant increase ( , < 0.
