    Analytical Methods for Atmospheric Carbonyl Compounds: A Review by Xiaoshuai Gao, Xin Zhang, Yan Nie, Jiemeng Bao, Junling Li, Rui Gao, Yunfeng Li, Wei Wei, Xiaoyu Yan, Yongxin Yan, Hong Li

    Published 2025-01-01
    “…For multiple carbonyl compounds, offline detection results were greatly influenced by detectors coupled with chromatography, whereas online monitoring techniques were applicable to all types of volatile organic compounds (VOCs), including some carbonyl compounds, providing higher temporal resolution and improved isomer identification with the development of online mass spectrometry. The combined use of proton transfer reaction-mass spectrometry (PTR-MS) and liquid chromatography-mass spectrometry (GC-MS) was suitable for the detection of carbonyl compounds in atmospheric photochemical smog chamber simulation studies. …”

    Thaliporphine from Berberis lycium Royle by Syed Fazal Hussain

    Published 2024-09-01
    “… Chemical studies on the aerial part of Berberis lycium Royle belonging to the family Berberidaceae resulted in the isolation of the aporphine alkaloid ‘Thaliporphine’, the structure of which was elucidated by using spectroscopic techniques such as 1H NMR, 13C NMR, DEPT-90, DEPT-135 and Mass spectrometry. Although only nine aporphines have been isolated from different Berberis species, this is the first report of the isolation of thaliporphine from Berberis lycium.  …”
