Enrichment of the flavonoid fraction from leaves by a liquid antisolvent precipitation method and evaluation of antioxidant activities and .

leaves originate from the dry leaves of the plant. Flavonoids are the main functional components of leaves. Some flavonoids such as rutin, kaempferol and quercetin are rich in , and they have outstanding antioxidant efficacy.

Improved hydrogen production from pharmaceutical intermediate wastewater in an anaerobic maifanite-immobilized sludge reactor.

A novel anaerobic maifanite-immobilized sludge reactor (AMSR) was employed to investigate the feasibility and performance of continuous hydrogen production for the treatment of pharmaceutical intermediate wastewater (PIW) at different organic loading rates (OLR) (from 12 to 96 g COD L d) according to changes in the hydraulic retention time (HRT). A reactor without maifanite was also employed as a control. The results indicate that maifanite accelerates granular sludge formation and the AMSR presents more efficient and stable performance than the control in terms of the hydrogen production rate.

Comparison of the performance of magnetic targeting drug carriers prepared using two synthesis methods.

In this paper, two methods were used to prepare the magnetic targeting drug carrier FeO-PVA@SH, the step-by-step method and the one-pot method. The loading and release properties of the compound were measured. The results show that the FeO-PVA@SH prepared using both methods exhibited excellent drug delivery properties in an environment that simulates human body fluid (pH 7.
