Summary: In recent years, there has been an increased interest in products of natural origin. The extraction procedure of bioactive compounds from plant matrices is a crucial step in the development of useful new bioproducts for everyday life. The utilisation of analyses enabling the rapid identification of the presence of a given group of compounds can be helpful in the early stages of the development of new products in order to save time and reduce costs. Within this article, we have presented a comparison of different, accessible methods for the identification of various bioactive compounds, e.g., saponins, carboxylic acids, oils and fats, proteins and amino acids, steroids, and alkaloids in plant-based extracts. Additionally, the multielemental composition of extracts was also examined. The applied methods allowed for confirmation of the presence of biologically active compounds in bio-products obtained by ultrasound-assisted extraction. At a later stage, these procedures should be supplemented by advanced analytical techniques in order to determine the plant chemicals' content qualitatively and quantitatively.

Summary: A new ultrasound-assisted cold brewing (UAC) method was established to improve the production efficiency of cold coffee brewing. The UAC coffee extracts showed higher levels of total dissolved solids, total lipids, proteins, and titrated acids compared to static cold brews. The volatile compounds in UAC were similar to static cold brews, indicating that ultrasonication compensated for the longer extraction time of static cold brewing. This study demonstrated that ultrasound-assisted cold brew can enhance the flavor and extraction efficiency of coffee, providing an option for accelerating the cold brew coffee process.

Summary: Two different silver(I) complexes with diphenylphosphonic acid as peripheral ligand were synthesized using different solvents. The complexes were characterized by X-ray photoelectron spectroscopy (XPS), infrared spectroscopy (IR), elemental analysis (EA), and thermogravimetric analysis (TG). Single crystal X-ray analysis determined the final structure of both complexes. The interaction modes of the complexes with DNA were studied using fluorescence and electrochemical analysis. The results showed that the complex with methanol solvent had a more stable binding with DNA and protein compared to the complex with DMF molecule.

Summary: We have synthesized two new Co-CPs with different structures by adjusting the concentration of cobalt ions. CP 1 is a three-dimensional pillar-layered network with a 10-connected topology, while CP 2 is a three-dimensional reticular framework with a (4,4,5,5,6)-connected topology. The structural diversity of the two CPs is attributed to the variation of cluster numbers and local coordination geometries of Co(II) ions. The magnetic interactions between cobalt ions in CP 1 and CP 2 are different, with ferromagnetic coupling in CP 1 and antiferromagnetic behavior in CP 2.

Summary: We designed a powerful ClO- probe called ETMC, which exhibited aggregate-induced emission (AIE) characteristic in solid state and water/EtOH binary solvent. The probe ETMC showed colorimetric and ratiometric response to ClO- with high selectivity and sensitivity, and a low detection limit of 3.66 x 10-7 M. Moreover, probe ETMC could be applied to visibly and quantitatively detect different concentrations of ClO- in test paper. Importantly, probe ETMC effectively detected endogenous and exogenous ClO- in living A549 cells through an outstanding ratio signal change. The sensing mechanism of the probe ETMC for ClO- was confirmed by FT-IR, 1H NMR, HRMS, DLS, TEM, and DFT calculation.

Summary: Organic dyes are commonly used in various industries, but their uncontrolled discharge into water bodies has negative impacts on the environment. Metal-organic frameworks (MOFs) are versatile materials that can be used as photocatalysts. In this study, two porphyrin-based MOFs (TCPP-La and Fe-TCPP-La) were investigated for their photocatalytic activity in degrading dyes. The results showed that TCPP-La had better degradation efficiency for both methyl orange (MO) and methylene blue (MB) compared to Fe-TCPP-La, and the addition of hydrogen peroxide further improved their performance.

Summary: In this study, a biocompatible C-21 steroid caudatin (1) was isolated from C. otophyllum and characterized using multinuclear NMR spectroscopy and mass spectrometry. The obtained natural product was used as a photoluminescent sensor for selective and sensitive detection of cupric cation. Theoretical calculations indicated that the selectivity of caudatin towards Cu2+ was due to the better interaction between Cu2+ and caudatin as well as the competitive absorption of UV-Vis spectral overlap.
