This study revealed the optimal conditions for the Ultrasonic-Assisted Enzymatic Extraction (UAEE) of silymarin, and include: the concentration of ethanol, 50 %; enzyme concentration, 30 U/mg; liquid-solid ratio, 6:1; an extraction time of 120 min; and the ultrasonic power at 180 W. The extraction rate was 7.86 %, which is higher, by 74.67 %, than that of the silymarin extract from the Silybum ...

Previously we have shown that peroraly administered silymarin, a mixture of antioxidant flavonolignans from medicinal plant Silybum marianum (L.), prevents both the accumulation of exogenous cholesterol in the liver and the development of diet-induced hypercholesterolemia in rat1, 2. The silymarin-induced decrease of plasma cholesterol has been associated with a decrease in apo B containing lip...

Silymarin is a hepatoprotective mixture of flavonolignans and flavonoids extracted from the seeds of milk thistle (Silybum marianum L. Gaertn). This study investigates the effect of major bioactive constituents from silymarin, silybin A, silybin B, isosilybin A, isosilybin B, silydianin, silychristin, isosilychristin, and taxifolin, on the expression of ABCA1, an important cholesterol efflux tr...

Seeds of Silybum marianum which have been used to treat liver diseases have an active component called silymarin. Hairy root cultures of S. marianum could be able to produce silymarin. There is evidence that the use of elicitors has been an important strategy for improving the production of secondary metabolites. Elicitation is an interesting topic to investigate cell signaling pathway in secon...

Purpose: To develop a nanosuspension drug delivery system to enhance the dissolution rate of Silybum marianum seeds extract.
 Methods: Central composite design was used study effect input variables (stabilizer plant extract ratio, antisolvent solvent stirring time) on dependent (mean particle size, polydispersity index (PDI) and zeta potential). The optimized formulation characterized by S...
