“…Furthermore, the nanosponge morphology of the macroscopic aggregate ( Fig. 5) is similar to that of Ag nanosponges prepared by reduction of silver nitrate in a multicomponent system and by a subsequent thermal fusion during shaking at 60°C [26] as well as to Ag-quantum dots sponge-like nanocomposites. [27] Concerning the employment of the nanostructures for the purposes of SERS spectroscopy, the major difference between the last mentioned Ag nanosponges, [26,27] as well as the other types of recently prepared Ag nanostructures, [28,29] and the macroscopic nanosponge Ag aggregates reported in this paper is that the analyte has been already incorporated into their fractal building blocks.…”

Adsorbate‐containing, nanosponge Ag aggregates overlayed by a thin (~1.5 mm) liquid layer are reported as a new type of sample for Surface‐enhanced Raman scattering (SERS) microRaman spectral measurements and adsorbate (analyte) detection. Macroscopic Ag aggregates (of about 1.5 × 1.0 × 0.025 mm size) with the nanosponge internal morphology (revealed by Scanning electron microscopy (SEM)) were prepared by 3D assembling of fused fractal aggregates (D = 1.84 ± 0.04) formed in Ag nanoparticle hydrosol/HCl/adsorbate systems with 2,2’‐bipyridine (bpy) and/or a cationic free‐base tetrakis(2‐methyl‐4‐pyridiniumyl) porphine (H2TMPyP) as the testing adsorbates. For SERS microRaman measurements, the macroscopic aggregate was overlayed by a thin (~1.5 mm) layer of the residual liquid. Preparation procedure, nanoscale imaging, and SERS spectral probing including the determination of the detection limits of the adsorbates revealed the following advantages of the adsorbate‐containing, liquid‐overlayed 3D nanosponge aggregate as a sample for SERS microRaman spectral measurements: (1) localization of adsorbate (analyte) into hot spots and, simultaneously, prevention of the analyte decomposition during the spectral measurement (carried out without an immersion objective), (2) fast and simple sample preparation, and (3) minimization of sample volume and an efficient concentration of hot spots into the focus of the laser beam. The advantages of the nanosponge Ag aggregates are further demonstrated by the 40 fmol limit of detection of bpy as Ag(0)‐bpy surface complex, as well as by preservation of the native structure of the cationic free‐base porphyrin H2TMPyP.

“…The chemical structures of the known compounds were determined by comparing their spectroscopic data (ESI-MS and NMR) with data already reported in the literature. These compounds were determined to be luteolin (2) [8], 7,3 0 ,4 0 -trihydroxyflavanone (= butin) (3) [9], cassiaoccidentalin B (4), cassiaoccidentalin A (5) [10], tetrastigma B (6) [11], butin-7-O-b-D-glucoside (7) [9], luteolin 7-O-b-D-glucoside (8) [12], butein (9) [13], butein-4 0 -O-b-D-glucopyranoside (10) [9], p-coumaric acid (11), and ferulic acid (12) [14]. Among these known compounds, 7 and 9 were first identified from the genus Cassia, and 4 -6 and 10 -12 were initially isolated from C. nomame.…”

A new C‐glycosyl flavone containing a 3‐keto sugar, isocassiaoccidentalin B (1), was isolated from whole Cassia nomame (Sieber) Honda plants, along with eleven known compounds, including two flavonoids (2 and 3), five flavonoid glycosides (4 – 8), two chalcones (9 and 10), and two phenylpropanoids (11 and 12). The chemical structures of all compounds were determined via 1D‐ and 2D‐NMR, and ESI‐MS. Among these, compounds 2, 3, 7, and 8 were found to be the most potent in inhibiting nitric oxide release. Compounds 1, 2, 4, 8, 9, and 10 showed significant free‐radical scavenging activity.
