[Photo-assisted Degradation of Sulfamethazine by Ferrocene-catalyzed Heterogeneous Fenton-like System].

Antibiotics are acknowledged micropollutants in wastewaters and surface waters. They are of particular concern because they can trigger an increase in resistant bacteria. Therefore, novel and efficient technology for the removal of antibiotics is urgently needed.

Cytotoxic triterpenesaponins from Ilex pubescens.

Two new triterpenesaponins, ilexsaponins G and H (1 and 2), together with six known triterpenesaponins (3-8), were isolated from the roots of Ilex pubescens. Their structures were elucidated on the basis of spectroscopic evidence and hydrolysis products. Those compounds showed inhibitory activities against two human colorectal cancer cell lines HCT 116 and HT-29.
