Biotransformation of Ambrisentan by A. niger and P. mineoluteum Monitored by High Performance Liquid Chromatography and Ultra High Performance Liquid Chromatography/Quadrupole Time‐of‐Flight Mass Spectrometry

SEPARATION SCIENCE PLUS, Volume 8, Issue 6, June 2025.
ABSTRACT The focus of the present study was the monitoring of ambrisentan (AMB) in vitro biotransformation by two fungal cultures: Aspegillus niger ATCC 9029 and Penicillium mineoluteum URM 6889. This drug is a selective endothelin Type A, receptor antagonist, used for pulmonary arterial hypertension.

A green separation mode of synephrine from Citrus aurantium L. (Rutaceae) by nanofiltration technology

Food Science &Nutrition, Volume 7, Issue 12, Page 4014-4020, December 2019., 2019
Thermal breakage of alkaloids ingredients was a common problem to which attention should be paid in the application of fruit ingredient separation. In this study, the mathematical models were based on the operating pressure and initial concentration to predict the rejection of synephrine.
